šŸ‘‹ Hi all, Jonathan from Golioth (https://golioth.io,) and IoT platform that already works great with Adafruit boards. Any ESP32/ESP-IDF users out there? We just made it easier to add a couple of cloud functions without having to become an AWS or Azure expert. We're also going to continue building out training for ESP-IDF https://blog.golioth.io/announcing-the-golioth-esp-idf-sdk/.

Hey, do you know great low-power mcu+ gsm/gps modules that work in europe and can be woken up with movement/accelerometer, sms, call or data?

#

Suitable for battery-powered setups.

#

@carmine trail I saw you did some work on the The BLE friend firmware. After reading around some, is it correct that it is uploaded to the device presuming the device has the nrf supplied bootloader?

#

If you don't the question šŸ˜…

Probably counts at IOT. Just automated my iPhone to send battery level to adafruit.io automatically when plugged in. Completely native using iOS shortcuts. Works like a champ. Which also means I could send events if a HomeKit bulb is flipped on as an example. If any interest I can post clean screenshots of the shortcuts involved.

# severe socket interested!!

Cool. Iā€™ll post it later tonight. Pretty simple once youā€™ve seen it. I have my iPhone and iPad posting battery level each time I plug them in.

mighty mountain
#

First I made one shortcut to send whatever payload. Just put in your token. It will expect the webhook url be in payload which will be shown in second shortcut

#

Yeah I have extra fields io we hook will ignore. But i have them there in case I wanted to use a raw endpoint

#

Put appropriate feed url in webhook dictionary spot for what youā€™re sending to.

I am wanting to assemble some IoT monitoring devices to sit around the house. I am trying to run the following sensors: BH1750 (I2C), AHT20 (I2C), AM312 PIR, KY-037 Sound Sensor, 4x Reed Switches to monitor doors. Therefore, I need 8 pins - 2 for SCL/SDA, 6 digital inputs (4x with pullups).
I am planning to use Home Assistant with ESPHome
I was hoping to use NodeMCU v3 but I don't think there are enough pins without giving me a headache.
Can someone recommend another board that will give me enough pins - preferably without breaking the bank (as I need 4 of them and the NodeMCUs I can get for Ā£3)

vestal rover
#

Presumably an ESP-WROOM-32D or the ESP-WROOM-32 (the 38pin version) would work?

vestal rover
#

Solved it by adding a PCF8574 - I2C so not using any pins and gives me 8 extra pins šŸ˜„

Anyone using AT Commands over a cellular module? Trying to find a resource to help handle At cmd errors.

#

Does anyone use the ESP-IDF? I have a brand new esp32s2 Feather (w/ bme280) and I consistently get errors when flashing (OSError: [Errno 71] Protocol error) with idf.py. I've tried everything I can think but was hoping someone might have an idea before ruling out faulty hardware.

urban spruce
#

actually let me step back

#

are you compiling the bme280 example in the idf?

#

or are you trying to put circuitpython/arduino onto the feather?

silent canopy
#

I'm not even touching the sensor - just trying to flash a hello world.

#

I've checked permissions, OS packages, IDF and those tools, USB cable...

urban spruce
#

Press and hold boot, then press reset and release boot after that

silent canopy
#

I did. The flashing process wouldn't start otherwise

urban spruce
#

Gotcha. Very interesting

silent canopy
#

Is it possible that the Feather needs to have specific pin held high or low? Besides the BOOT one?

urban spruce
#

I suspect there might be something else going on. Unfortunately I donā€™t have a Linus box to validate against.

#

Are you able to load circuitpython onto the feather at all?

silent canopy
urban spruce
#

Okay, try erasing first and then programming if you arenā€™t already

#

There is a weird issue Iā€™ve seen where if you donā€™t erase the chip before loading new firmware, it has issues.

silent canopy
#

It's very weird. I've erased it several times now.

urban spruce
#

Are you using the tip of their main branch? Or are you on like 4.4?

#

It might be worth trying to switch to one of the release branches

# icy hazel I'm in UK and we still have 3G and 2G for a while

2G is not for long in this country, but strangely will be supported longer than 3G as mentioned in this doc it will be switched off After networks have decommisioned 3g. Even 3G already has a switch off date on some networks (vodafone 2023) https://www.ofcom.org.uk/phones-telecoms-and-internet/advice-for-consumers/advice/3g-switch-off

#

To Adafruit moderators, are there plans to have CP boards compatible with Matter, the new IoT standard?.

willow spear
#

Ohhh that would be sweet

wicked elbow
#

it's IP-based and would probably need changes in the core, and SDK changes (espressif has a Matter SDK, but it's separate from the esp-idf that we use afaict; I couldn't find anything for raspberrypi Pico W)

#

those wifi devices should be fine hardware-wise though

#

less likely to see it on Airlift or Ethernet, I suspect

urban spruce
#

Youā€™d probably still send data to/from the airlift over SPI.

wicked elbow
#

that would probably be easier to implement than conjoining Matter protocol to the existing NINA firmware, but might mean no co-existence of Matter and the present TCP/UDP protocols

#

on espressif, for example, I'd want Matter and all of the existing IP functionality, which comes naturally when adding Matter to the core with a helper Python library

urban spruce
#

It would probably be easier to use matter and TCP/UDP together on an Espressif airlift than the new NRF7002

wicked elbow
#

right, but either Matter has to get shoehorned into the existing NINA, or the Matter firmware needs to support the full range of protocols (essentially re-implementing NINA)

#

NINA is currently based on espressif's Arduino core (a mash-up of Arduino and esp-idf)

urban spruce
#

Yeah, Iā€™m optimistic that we could get beta Matter support on CP9

royal falcon
#

A natural follow on from Matter support in CP would be a Thread featherwing.

pine furnace
#

I think its a bit early because commercial Matter products aren't really out though

#

I saw an article about diy matter devices and can't find it now

urban spruce
void solstice
#

Shouldn't have to wait for commercial products to become available in order to figure out how to get the functionality out of programmable devices.

Sort of in the airlift manner

#

Since using zephyr with circuitpython is in limbo which would make it difficult to deploy natively in circuitpython.

Cross posting from #help-with-wippersnapper-and-adafruitio
Hi everyone - finally got around to playing with my Adafruit Fun House and I'm interested to understand how I output the temperature AND humidity AND barometric pressure to shoot out to a Feed. I tried to mod the Temperature example (https://learn.adafruit.com/creating-funhouse-projects-with-circuitpython/temperature-logger-example)

Questions

  1. Can an Adafruit IO feed have multiple data points coming from the Funhouse?
  2. Is there an example of pushing out multiple pieces of data from the Fun House out to Adafruit IO?

Anybody know if thereā€™s an open source SDK like rp2040 pico for the teensy 4.1?

#

And for stm32f7?

pine furnace

#

I think Teensy's aim is to work with Arduino? But yeah, stm32 has a very vibrant community

#

for teensy you might look at the chip? NXP's imx.rt.something I think for the 4.x?

median pilot
#

i think ST has relicensed their "open source" firmware libraries/SDKs to have restrictions that are no longer compatible with some (many?) open source licenses, probably because of the emergence of clones of their MCUs

urban spruce

#

ya, I only mean "open source" as-in you can read it

#

many vendor hals have clauses that you can only use the code on their micros

#

The startup I briefly worked for over the summer used a CEL module that used a Realtek WiFi/BLE module and a majority of the documentation and macros was behind NDA due to restrictions Realtek placed on the chip users

anyone have experience hooking up feather32's to Home Assistant via the ESPHome tools? I have multiple boards (S3 from UM, Huzzah32, Feather S2) and all of them give me grief in getting the esphome environment loaded. I have tried from Mac and Linux computers, now I am going to try the Borg variant and see if I can find a work around. I keep seeing hints about holding the boot button down, but that doesn't seem to work either. TIA for any hints.

#

I was able to get the UM feather to take the code. It worked as expected where I held the boot button just as one would to flash a new version of circuitpython. However, doing the same for the adafruit feather would stop at the boot partition, but the esphome flashing tool would never succeed from the chrome web serial tool, it failed when hooked directly to usb cable on PI (homeassistant server) and it failed the same way from both Windows10 and MacOS. I think I may have to dig in and get down to a cli tool. The cables are known good, the issue above would be something I may encounter a few steps deeper into the process (appreciate that tip). I have had great luck with D1 minis (esp8266) and with some other brands of esp32, but I really, really wanted one with stemma connectors so I could simplify the prototyping while sorting out quick ways to focus on the HA/ESPHome automation and scripting elements, not spend so much time tripping over my shoelaces with things like a bootloader being in the way. Alas tools like WLED also reject a lot of new products as not supported yet. ah the fun of bleeding edge toys. šŸ™‚

#

My chief concern was that perhaps serial port drivers were getting in the way, and in modern linux kernels have not had to monkey with drivers like on windows and to a lesser extent on macos. I think that is less likely the issue ATM.

#

but my linux box refuses to let me run chrome (needed for web serial stuff) due to rolling release grief unrelated to this topic.

#

I found the esphome discord, so I may try some probes over in that space.

i need help with esp mesh network

#

Just trying to Build a simple mesh network Using three devices, 2 esp8266 and 1 esp32, they are all abe to communicate to each other but i want the esp32 to be able to send requests to servers on the internet

#

I am using the following code in arduino ide

# 
#include <HTTPClient.h>
#include <WiFi.h>

#define   MESH_PREFIX     "Things_Mesh_Network"
#define   MESH_PASSWORD   "thingsmesh"
#define   MESH_PORT       5555

// Replace the following with your home WiFi name and password
const char* WIFI_SSID = "Wifi_02";
const char* WIFI_PASSWORD = "wifi_optix";

Scheduler userScheduler;
painlessMesh  mesh;

HTTPClient http; // Create an HTTPClient object to make HTTP requests
WiFiClient wifiClient; // Create a WiFiClient object to use for the HTTPClient object

void sendMessage();

Task taskSendMessage( TASK_SECOND * 1 , TASK_FOREVER, &sendMessage );

void sendMessage() {
  Serial.println("sendMessage()");
  String msg = "hello from node 3\n";
  msg += mesh.getNodeId();
  mesh.sendBroadcast( msg );
  taskSendMessage.setInterval(1000);
}```
# 
  Serial.println("receivedCallback()");
  Serial.printf("startHere: Received from %u msg=%s  \n", from, msg.c_str());
  
  // Make the GET request to Google
  http.begin(wifiClient, "http://www.google.com");
  int httpCode = http.GET();
  String payload = http.getString();
  Serial.printf("HTTP response code: %d\n", httpCode);
  Serial.printf("HTTP response payload: %s\n", payload.c_str());
  
  // Close the HTTP connection
  http.end();
}

void newConnectionCallback(uint32_t nodeId) {
  Serial.println("newConnectionCallback()");
  Serial.printf("--> startHere: New Connection, nodeId = %u\n", nodeId);
}

void changedConnectionCallback() {
  Serial.println("changedConnectionCallback()");
  Serial.printf("Changed connections\n");
}

void nodeTimeAdjustedCallback(int32_t offset) {
  Serial.println("nodeTimeAdjustedCallback()");
  Serial.printf("Adjusted time %u. Offset = %d\n", mesh.getNodeTime(),offset);
}```
# 
  Serial.begin(115200);
  pinMode(LED_BUILTIN, OUTPUT);
  digitalWrite(LED_BUILTIN, LOW);

  // Connect to your home WiFi
  WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }
  Serial.println("Connected to WiFi");

  mesh.setDebugMsgTypes(ERROR | STARTUP); // set before init() so that you can see startup messages

  mesh.init(MESH_PREFIX, MESH_PASSWORD, &userScheduler, MESH_PORT);
  mesh.onReceive(&receivedCallback);
  mesh.onNewConnection(&newConnectionCallback);
  mesh.onChangedConnections(&changedConnectionCallback);
  mesh.onNodeTimeAdjusted(&nodeTimeAdjustedCallback);

  userScheduler.addTask(taskSendMessage);
  taskSendMessage.enable();
}

void loop() {
  mesh.update();
}
#

I get this output in serial console

Screenshot_2023-03-27_at_3.03.09_AM.png
#

HTTP response code: -1
My internet is working
Esp32 does connects to my wifi successfully before making the request

#

Can't figure out why is that happening, just wanted to confirm if this is even possible for esp32 to connect to a Wifi access point while being in Mesh Network?

#

Any Help would be very appreciated

blissful perch
#

@uneven spindle I'm not sure how ESP's mesh works, but it's unlikely that you can connect to both at the same time.

#

All the nodes in the ESP Mesh network can get IP connectivity and communicate both with each other and the external world. The internet access of these nodes is provided by a root node acting either as a NAT or a bridge.

#

The question then would be if painlessMesh supports it -- it looks like maybe not?

uneven spindle
blissful perch
#

painlessMesh doesn't appear to do that; instead they are just addressed by their chipId, not an IP, and it's not a TCP layer; you just send JSON objects back and forth

uneven spindle
blissful perch
#

so it's a bit of a simple & easy solution to get going quickly exchanging messages over mesh, but perhaps not suitable for bigger tasks

blissful perch
#

(i.e. one node would connect to the internet, and other nodes could connect to the internet routed through that one)

uneven spindle
#

Also it looks like that official "ESP-Wifi-Mesh" is only available for ESP IDF

blissful perch
#

aha, right.

#

in that case, if I were in your position, depending on what you're trying to achieve, I'd likely have one ESP that's dedicated to connecting to the internet, and then it connects directly to one of the mesh nodes (via UART/I2C/whatever), and that node is the designated 'connected to the internet' one which can service requests by funnelling them over to the wifi-connected one

uneven spindle
#

so now i am trying to setup ESP-IDF on my mac

#

But getting this error now

Screenshot_2023-03-28_at_5.59.19_AM.png
#

even though all environment variables are set

blissful perch
#

I'm afraid this isn't really something I can assist with; good luck!

uneven spindle
#

ok thanks anyways

#

ok found the solution, I need to run get_idf every time i restart the terminal

spring otter
#

nRF52840 can use it (Nordic dev kit avail)

tough gorge
#

I mean yes, if you build a microcontroller that has the appropriate firmware to compromise the CAN network and supports Ethernet, then plug said controller into your headlight and the Internet, then sure, it's IoT

urban spruce
#

IoT is a pretty broad definition though. I still tend to think the hack as being IoT hack because of the nature of electrical systems within vehicles

#

Physical access or not.

tough gorge
#

So is hotwiring a car an IoT attack?

urban spruce
#

Depends on the ignition system

celest pebble
#

The 1990s serial device I have on my desk is now iot because the python script that controls it communicates over mqtt. on the internet. if the attack came from the internet, I could see it being called an iot hack. If I connect directly to the serial device, with no internet, it's just a serial hack

urban spruce
#

IoT is just a term for a network dependent system. Being wireless isnā€™t a guaranteed feature.

#

Plus many of the systems in a car can be accessed/diagnosed over the internet.

celest pebble
#

so, and air gapped lan, is attacked by physical access, is still an iot hack?

urban spruce
#

Subaru vehicles for instance collate data and send it to their MySubaru app for end users to conveniently see

#

Could be, the definition of IoT doesnā€™t preclude air gapped networks nor does it preclude computers as far as I am aware.

#

But itā€™s generally applied to network dependent peripherals

#

Computers arenā€™t inherently network dependent, though you might say they are today because of how updates are administered

celest pebble
#

"Internet" kind of defines the network though

urban spruce
#

We can define internet at different levels though. Locally, regionally, globally..

#

Anyway

#

Iā€™m just saying IoT is a loaded term

#

It depends heavily on context and the developer

brisk marlin
#

word erosion, I'd assume it was at least an internet adjacent thing, but in a few hundred years it'll probably mean just about anything

midnight cove
spice palm
#

IoT was most likely used because itā€™s a ā€œhotā€ term to use in a headline

#

But I would argue that if a device on the CAN network also has some wireless protocol on it that can be exploited, then sure i guess it can be considered an IoT attack

Hello all,
Iā€™m work on one IoT project and that include NodeMCU as a programming module and here I programmed this module on Arduino IDE software. My program uploads in NodeMCU but garbage value is shown in serial monitor. Which message I have pre-defined in Serial.print or Serial.println function, these garbage values are showing instead and my real data is not showing. I can't find any solution to this problem. I did a lot of research but did not find a solution that could solve the problem. I am requesting here for the solution of my problem. if anyone has a solution to this problem then please let me know how to fix it . So, that I can come out of this problem.
Thank you.
NOTE: The program that I use and the garbage value that comes in the serial monitor is in the word file that I have given above. Please open that file to see the output of the program and serial monitor.

# idle hare Hello all, Iā€™m work on one IoT project and that include NodeMCU as a programmin...

The garbage data looks like itā€™s part of the esp8266 boot code, which for whatever reason runs at a baud rate of 74880. I think the design is intended to separate the boot loader output from the application output, but it does create an ugly mess before your code even begins its serial output.

If you look at the end of the garbage data, you do see your serial print outputs like ā€œBootingā€¦ā€ and ā€œWiFi connected.ā€ The garbage is part of the esp8266 startup, so if you can ignore it, perhaps just add some new lines before your first println() to separate it from your own code output. Your data looks fine, youā€™re just hitting the watchdog reset because your MQTT is unreachable for some reasonā€¦

wind olive
#

On the ESP8266 I usually go with just setting serial output speed to 74880 so that I can easily read whatever CPU exceptions may be happening as well as my code's output.

#

Yeah, the ā€œgarbageā€ is now proper readable output from the boot loader. Canā€™t suppress it unless you use a different serial port for your application output, and Iā€™m not immediately familiar with your alternatives.

Sorry, I probably can't really help. But is the garbage Serial output actually a part of the problem? Or is only the "can't connect to the MQTT stuff" the problem?

meager elm
# idle hare Okay, now you can say me what can I do to solve problem?

Ah, thatā€™s what you meant by garbage. Yeah thereā€™s something wrong with your MQTT credentials. Either your AIO key/user/port isnā€™t working right, or your device connected to Wi-Fi isnā€™t connected to the internet properly. Iā€™d recommend double checking your credentials.

On that note, you probably donā€™t want to share your AIO key or username, or your Wi-Fi credentials, in a public server. Iā€™d strongly recommend you reissue a new key and redact those values in future inquiries.

it is visible in the serial terminal and reviewing your code that it never connected to wifi

idle hare

Those have been repeatedly explained

#

There are no garbage values in your output. Only boot output from the esp itself that you captured at the wrong baud rate, then a memory dump when your application crashes, presumably trying to communicate with an mqtt server without a valid connection

Also if your WiFi password is legitimately 123456789, please change it

You have an unset IP address. This means WiFi set up failed

But,
When I try to connect the NodeMCU to WiFi, it connects but disconnects within a few minutes after connecting. And this process repeats when NodeMCU tries to connect to WiFi.
Please say me, what can I do at this moment?

If you were getting started on an IoT platform today, what would you use? How would you choose differently based on household vs commercial vs industrial use?

meager elm
# open blade If you were getting started on an IoT platform today, what would you use? How wo...

For a household, something thatā€™s widely available and easy to integrate is ideal, so something like an esp32 is perfect. Itā€™s not particularly expensive, and ties into your existing network without too much extra effort.

For commercial or industrial use, wide adoption is far less critical compared to security. While the esp32 does have some features that helps in that department, itā€™s so well known that itā€™s not nearly as hard to target as a vulnerability compared to some of the more sophisticated security solutions other more expensive platforms offer.

Canā€™t say I do a lot of iot work, so thatā€™s about the extent of my opinions based on my hobbyist experience and knowledge.

open blade
#

I've seen some platforms? that have cryptography chips built in, but I'm not sure what they do beyond calculate crypto algos quickly(if even that)

meager elm
#

No names come to the top of my mind. Cryptography chips are great, but technically even the ESP32 has them, so it comes down to firmware and software implementation in most cases.

open blade
#

That makes sense

#

Do you know if the ESP32 is considered open and free? I noticed it has secure boot but is optional

meager elm
#

Cryptography chips can be thought of as dedicated encoding/decoding hardware, something that takes the load off the main processor and hides the private key from anyone who could otherwise extract them from a firmware image dump.

open blade
#

Oh yeah hiding the private key is nice

meager elm
#

Open source is usually used in the context of circuit design and software. You would be very hard-pressed to find an open-source IC designā€¦

cunning dust
meager elm
#

Technically RISC-V is an open source core, but the ESP32 family of chips are not that.

#

Even if some variants do use a RISC-V core, the chip itself, as all commercially available chips I know of, are not of themselves open-source.

cunning dust
meager elm
#

Ah, thanks for the correction.

cunning dust
#

A number of vendors claim their architectures are "open" without really specifying what that means. Intel for example loves to blast Apple by saying that x86 is an open architecture, but in practice that really only means that they are willing to sell you their chips if you give them enough money. Keep in mind that you would have to sign multiple NDAs in order to access the necessary documentation required to design and build an x86 platform.

meager elm
#

Oh, @open blade when you ask regarding platforms, are you asking about hardware or software platforms? I know almost nothing about the latter šŸ˜‚

open blade
open blade
cunning dust
#

Well, that's definitely not true on x86.

#

Or most other platforms capable of running a full OS.

open blade

It's far more achievable on RISC

But the Librem 14 uses a core i7 so idk šŸ˜…

jaunty sun
#

but its x86 compatible, so isnt it just another implementation of x86?

#

and yeah, getting it to 5ghz is the real challenge, the same one every cpu vendor spends decades trying to solve

RISC makes such implementations simpler

but, is there any legal trouble, with creating a clone of x86 like that?

or any other ISA

I need to get several reed switches hooked up in a way that is 'converted' to i2c. Does such a board already exist?

wicked elbow

@wintry current a reed switch closes a connection, so you can use it to toggle the value of a GPIO. To convert GPIO to I2C, there are a number of boards available. For example: MCP23008, PCF857x (light internal pull-up), AW9523 (requires external pulls), or Seesaw https://www.adafruit.com/search?q=seesaw

Using an RP2040 to Cellular modem over UART I normally can send and receive messages. After an episode of occassional byte dropping on GET/READ AT Commands, I tried using Xflow with CTS and RTS connected and supplied. We also tried increasing the buffer size from the default 64 to 512. Things are much better but not 100%. Any advice to further reduce or eliminate byte dropping wuld be helpful.

wicked elbow
#

other levers: adding a parity bit, adding a second stop bit, checking for sources of interference, reducing baud rate if performance requirements allow

#

if RAM allows, increase buffer size more

#

depends on what you think likely causes are for dropping bytes

Are there implementations of Matter for pi picos or zeros or CircuitPython

loud belfry

wind olive
# loud belfry The only one I'm aware of is by Sparkfun: <https://www.sparkfun.com/products/202...

That Sparkfun product name is really misleading. The special thing about it is that it has a Thread radio, not that it supports Matter - lots of CPUs run Matter. The reference implementation of Matter also runs on virtually any ESP32, including any Sparkfun or Adafruit ESP32 board. Their choice of names just adds to the general confusion many people have about Thread and Matter.

good to know

wind olive
# graceful gate Are there implementations of Matter for pi picos or zeros or CircuitPython

The reference implementation of Matter includes Linux support, so it should be possible to run it on a Pi Zero W under Raspberry Pi OS. I'm a little surprised that no one has ported it to the Pico W yet, though it's possible that either a Pico port would be too memory-constrained or that the Pico may not be able to do crypto fast enough to make it work well. It definitely runs well on ESP32 CPUs though.

The size and complexity of Matter may make CircuitPython support challenging as CircuitPython also adds a lot of overhead and between it and Matter even ESP32s may feel resource-constrained. But I expect someone will take a shot at it eventually. I wouldn't expect it to be feasible before CircuitPython 9.0 is out and the ESP32 port is based on ESP-IDF 5.0 or later as the Matter SDK requires more a recent ESP-IDF version than CircuitPython 8 uses. 5.0 had some major breaking changes from the older versions.

I'm wondering if adafruit sells a board that has a combined BLE and Wifi Module with UART Pairing/Bonding support?

wicked elbow
#

right now: the best BLE is on the nRF52840 boards... you can add an Airlift board to that (uses ESP32 as a wifi co-processor over SPI)

#

possible futures (not guaranteed): development of BLE on Pico [W], further development of BLE on espressif boards

tardy seal
#

What are the current problems with BLE on ESP?

stuck eagle
#

And they're still in development for full support

wicked elbow
#

There's also Airlift (ESP32 as SPI co-processor) as a partial BLE implementation:

#

On most other boards with adequate firmware space, BLE is available for use with AirLift or other NINA-FW-based co-processors. Some boards have this coprocessor on board, such as the PyPortal. Currently, this implementation only supports acting as a BLE peripheral. Scanning and connecting as a central are not yet implemented. Bonding and pairing are not supported.

Hello again... Ok, setting up my QT PY ESP32 S3 with the required code (https://learn.adafruit.com/temperature-and-humidity-sensing-in-home-assistant-with-circuitpython/code-the-sensor).

I created a "secrets.py" file with my info (using the default IP and PORT address on the page. Is this file supposed to be another name? Because I get the following error:

Traceback (most recent call last):
File "code.py", line 31, in <module>

Thanks for any help! ā˜ŗļø

@lyric dune are the os.getenv() parametrs in a settings.toml file?

or perhaps missing quotes somewhere

hi i have a question. I have to create a measuring instrument for a study. Now I have a metro m4 airlift that is used to send the data from a few distance sensors to my PC. Only now I also have to connect a giro, but no cable is allowed to run from the boat to the metro. so I thought I still have an ESP32 dev kit lying around so I can send the data wirelessly to the metro. now I know that ESP has a data protocol ESP-NOW. but can I also use this on that metro board?

#

then I'll look for something else. thank you

lyric dune
wicked elbow
#

@lyric dune You can create a file called settings.toml at that root level, and put the credentials from the learn guide in that file (instead of in secrets.py). Anything that's accessed by os.getenv("SOMETHING") in your code needs a corresponding entry in the settings.toml file.

lyric dune
#

Sorry to bother but this is getting quite frustrating... So, now I'm getting the following error:

Traceback (most recent call last):
File "code.py", line 31, in <module>
TypeError: object with buffer protocol required

Lines 31 & 32:
wifi.radio.connect(os.getenv("CIRCUITPY_WIFI_SSID"), os.getenv("CIRCUITPY_WIFI_PASSWORD"))
print("Connected to %s!" % os.getenv("CIRCUITPY_WIFI_SSID"))

#

I have the following in the os.getenv file and the settings.toml file

MQTT_BROKER = "192.168.1.1"
MQTT_PORT = 1883
MQTT_USERNAME = "My Network"
MQTT_PASSWORD = "My Password"

#

Also added the following into the settings.toml and os.getenv

CIRCUITPY_WIFI_SSID = "My Network"
CIRCUITPY_WIFI_PASSWORD = "My Password"

pine furnace
#

you could split line 31, store the ssid and password into variable and print them before passing them to connect

#

that way you can verify that getenv is working

lyric dune
#

I'll try that... Thanks @pine furnace !

lyric dune
#

I'm a terrible coder... Is this what you mean?

wifi.radio.connect(os.getenv("CIRCUITPY_WIFI_SSID"))
wifi.radio.connect(os.getenv("CIRCUITPY_WIFI_PASSWORD"))
print("Connected to %s!" % os.getenv("CIRCUITPY_WIFI_SSID"))

#

We terrible coders have to hold together

lyric dune
#

I made that change and still gives the same error. I've looked in the Home Assistant devices and it's not showing up. I have MQTT add-ons installed, so I'm thinking it maybe wants the Home Assistant u/p and not my WiFi credentials... but I really don't know.

#

Well, it's not the u/p ...

#

So now the error code is different...

Traceback (most recent call last):
File "code.py", line 31, in <module>
ConnectionError: Unknown failure 15

#

To me, this is a step forward.

wintry forge
#

Hmm, can you suggest the Code maybe?

wind olive
#

try outputting the SSID and password before you call connect to confirm that they're correct

#

wifi.radio.connect() wants your wifi credentials

lyric dune
#

Well, I changed that line to the following:

wifi.radio.connect(os.getenv("CIRCUITPY_WIFI_SSID")), (os.getenv("CIRCUITPY_WIFI_PASSWORD"))

It now connects to my network, bu now, I get the following error:

Traceback (most recent call last):
File "code.py", line 49, in <module>
File "adafruit_minimqtt/adafruit_minimqtt.py", line 560, in connect
MMQTTException: Repeated connect failures

mqtt_client.connect()

#

I'm guessing it's something in Home Assistant at this point.

wind olive
#

It depends on where you're running your MQTT broker, but most likely the broker isn't bound to a network interface and is only accessible from the computer (or container) it's running on.

You can test this by installing an MQTT client app on a phone or tablet and trying to connect to the broker using the same credentials as you're using in your CircuitPython program

lyric dune
#

Hmmm... Well, I followed the Learning Guide to the T. What I don't understand is that the block of code that is put in the config.yaml file is the only thing supposedly required for the Home Assistant side:

  sensor:
    - name: "Temperature"
      state_topic: "state/temp-sensor"
      unit_of_measurement: 'Ā°C'
      value_template: "{{ value_json.temperature }}"
    - name: "Humidity"
      state_topic: "state/temp-sensor"
      unit_of_measurement: '%'
      value_template: "{{ value_json.humidity }}"```
#

I set the MQTT username/password to both my Home Assistant username/password and to "none"

Also, I tried installing the MQTT Integration but it won't connect either. I'm rather flummoxed.

#

And FYI, line code 31 on the Adafruit Learn Guide is incorrect. It states the following:

wifi.radio.connect(os.getenv("CIRCUITPY_WIFI_SSID"), os.getenv("CIRCUITPY_WIFI_PASSWORD"))

The line that works is:

wifi.radio.connect(os.getenv("CIRCUITPY_WIFI_SSID")), (os.getenv("CIRCUITPY_WIFI_PASSWORD"))

hot seal
#

wifi.radio.connect(os.getenv("CIRCUITPY_WIFI_SSID"))

lyric dune
#

Thanks @hot seal !

I don't have any more issues connecting to the WiFi... But I still can't connect to the MQTT - even following the Learning Guide.

I could try using the alternative going through AdafruitIO (I have an account), but the whole point of Home Assistant is to keep everything local.

hot seal
#

Hmmm... I have some working examples ...somewhere...I'll see if I can dig them out. It may be a few hours -- I have some priority errands to run.

#

in Home assistant, I have sensor: - name: "ender5pro_temperature" unique_id: "ender5pro_temerature" device_class: "temperature" state_topic: "state/temp-sensor" unit_of_measurement: 'Ā°C' value_template: "{{ value_json.ender5pro_temperature }}" - name: "ender5pro_humidity" state_topic: "state/temp-sensor" unit_of_measurement: '%' value_template: "{{ value_json.ender5pro_humidity }}" so that looks like yours

#

Can you post your CircuitPython code? I am using a password on my Wifi -- not sure if that makes a difference

#

and on My Home Assistant

#

This is example that I am using. I t uses the older "secrets.py" for some of the settings. It may need some updates for current version of CP and the libraries. I'll try to update it whan I get back.

does assistant do OTA update of the sketch or access to raw packets, Im kinda confused how it helps mm and the difference with adafruit.io

#

I already have philips hue home and the home assistant support it so Id have to do supplmentary code (ie: implement polling the hue rest service) and I wonder if home assistant would be a better fit for that + iot mini-boxes with a single sensor, velcro, battery, pir sensor and small oled that send data every minute

naive obsidian
#

i've been rolling my own with the MQTT integration (not using auth, so no help for above), but you can also get nice really cheap sensors for things like zigbee and zwave if you set up the appropriate stick: that may be cheaper in the long run, but not quite as much fun as doing your own thang

fiery saffron
#

A bit of a side topic but my problem atm is putting them in a box / learning solidworks cloud to make box to improve my open-air "iot device" kept in perforated fridge tupperwares . My current sensor is a laser setup for knowing a door was opening, II is a water capacitance sensor that screams when water reach it and III) a SOT thermistor sensor that screams when I leave the stove on for 60 mins without the pir detecting any movement

#

I doubt zigbee / zwave have stuff for many of these uses, cost me about 30$ each in components (that I already have) that is what I want to integrate with home assistant and/or adafruit.io (and put them in std enclosures)

I got gifted a mailbox (https://yunhai.shop/products/taiwanese-mailbox) yesterday and I'm brainstorming things that I can do with it.

I've got a bunch of random electronic parts so I'm thinking I can do something fun with it, but would love ideas or suggestions. Right now what I'm thinking is swapping out the mail slot with an adafruit rgb matrix and swapping the window with a thermal printer that gives folks a nice message when they submit something.

I've got a bunch of loose arcade buttons and an rpi camera so I've got a lot of wiggle room to make something cool. Would love suggestions if y'all have any?

Which affordable sensor can I use to measure fluid level in a tank like generator fuel tank or elevated water tank?

cunning dust
#

Liquid level is sort of a tough one, depending on the type of liquid. Traditionally, floats have been used for that type of thing, but it is also possible to measure liquid levels capacitively IIRC.

#

Some types of ToF sensors could also be usable, if properly calibrated.

#

I think you will need to develop a device starting with these sensors and some algorithms to get results with certain accuracy. In industry applications this is usually done with ultrasonic sensors, however, those need to have contact with the liquid, e.g., this one:

https://autosen.com/en/Process-Sensors/Level-sensors/Electronic-level-sensor-G3-4M-AF004

Usually, the measurement is done over a longer timespan, so I would consider using an industrial grade device to avoid problems with corrosion etc.

I'm trying to spin up a MQTT client on the W5500-EVP-Pico board, and it seems to work pretty well publishing chunks of simulated sensor data every second or so. However, consistently after many hours of this it seems to get into an unreliable state where it hangs while listening, will publish a bit more if I connect over the serial console, but then hang soon after I disconnect from the console. After a microcontroller.reset() it seems to recover and start publishing again for several more hours until it again gets into this 'congested' state. Any idea what might be going on? Is the circuitpython MQTT generally robust enough to operate indefinitely/days at a time or is it not surprising that I'm running into this issue?

naive obsidian
#

my guess is that there's a memory "leak" where a buffer or some other memory container simply keeps accumulating

wicked elbow
#

@uncut tapir There's also some possibility that the socket connection stalls. I don't see this much in wifi-land, but I have a current WIZnet app that gets restarted somewhat frequently due to watchdog timeout during Requests.

uncut tapir
#

yeah, it's weird that I can get it to start going again by connecting to a serial port, but only for a little bit before it stalls again. I'm going to keep trying to see if I notice any specific pattern, and which functions it's stuck in when I ctrl-c out if the stall. In the meantime I'm going to spin up MQTT comms using an RPZero wireless to see how robust that is

naive obsidian
#

unfortunately, debug logging is probably not an option šŸ˜æ

if I can get consistent results I'll post where the hangup seems to be happening and maybe that will clue someone in who knows something

wicked elbow
#

you can try to catch the exception, and skip or retry

uncut tapir
#

yeah, a brute force way would be try/except and then hard reset. but I would like to understand the issue

tired coral
uncut tapir
#

it's the mpy version from the latest bundle, I'm on 9.0.0-rc.0

#

I could pop the .py versions on and see if that helps track things down

tired coral
#

Is it a timeout error?

#

v5.0.7 (2 from current) raises that on line 599

uncut tapir
#

yeah

#

am I possibly running into the loss of precision problem with time.monotonic?

#

since a hard reset fixes it?

tired coral
#

It's specific to the call, so you shouldn't. It's more that the call is taking too long...

uncut tapir
#

yeah, it does seem like it's hanging right before the timeout, which tracks with that

tired coral
#

You could download the py file and print out time.monotonic() - last_read_time to see what it is...

uncut tapir
#

yeah, I got the py file

#

I'm just soft resetting again and again, and the exception seems to occur at different places, now it's the mqtt complaining about no data received from broker...so there's likely something else going on...maybe memory leaks

tired coral
#

That's always frustrating when it's not the same thing...

uncut tapir
#

yeah

tired coral
#

Are you connecting once to mqtt, or just when you need to?

#

Also, with 9x there have been a lot of updates. I would make sure all your libraries are up to date

uncut tapir
#

I checked with discotool and it said everything was up to date

#

and it's been running fine for a couple of days previously

#

monotonic-last_read seems to always print 0.125

#

I connect to mqtt just once

tired coral
#

Which seems good. I might wait until it fails and see what it prints... Sometimes the timeout is too low for network hiccups...

uncut tapir
#

yeah, it prints 0.125, even when it timesout, that's what I see

# 
            if self._timeout > 0 and time.monotonic() - last_read_time > self._timeout:
                print(time.monotonic()-last_read_time)
                raise timeout("timed out")
#

what's weird is that I see it print out 0.125 a bunch of times even before it timesout, which I don't quite understand

tired coral
#

What is the value of self._timeout?

uncut tapir
#

0.1

#

precision of time.monotonic() seems to be 0.125

tired coral
#

Can you change the timeout?

uncut tapir
#

yeah, changing it to 0.2 seems to have fixed it for now

#

right now I just hardcoded it above the timeout check, not sure where it gets set normally

uncut tapir
#

ah, duh, I'm setting it when I initialized it in my code, probably just directly copied it from an example.

tired coral
#

I might recommend going to 0.5 or so, but you can totally run at 0.2 and see when/if it fails

uncut tapir
#

yeah, there's still something fishy going on where it runs for days, then doesn't run anymore unless I hard reset

tired coral
#

Unless I'm doing something time critical , I usually set pretty high timeouts

uncut tapir
#

yeah, I think I lowered it because I thought I needed a lower mqtt loop timeout for more responsiveness, and the mqtt loop timeout has to be larger than the socket timeout

tired coral
#

Yeah that's true...

uncut tapir
#

I'll try a timeout of 0.3 and see how far that takes me

#

thanks for helping me troubleshoot

tired coral
#

For sure!

hot seal
uncut tapir
#

Yeah, that was my first guess

#

But I tried replacing with monotonic ns and it didn't fix it

uncut tapir
#

Also, the client and broker are on the same computer so response time should be fast

uncut tapir
#

I opened an issue regarding this on github, so others can weigh in

tired coral
uncut tapir
#

not yet, I had done a hard reset so now I have to let it run a bit before I can test to see if it fixes the timeout.

tired coral
#

How often do you send a request? Might try to reproduce

uncut tapir
#

1/sec, you need to wait long enough for the precision of the monotonic value to reach the same value as your timeout

#

right now I've set my timeout to 12msec to try to speed up the error

#

but it will still take hours

#

probably

uncut tapir
#

started timing out at 12msec after ~3h or so, bumped the timeout to 20msec to have a more robust baseline to test against, so another couple of hours of waiting

#

fortunately I can tweak code and soft-reset as much as I need without resetting the monotonic precision

tired coral
#

That is handy indeed...

#

I can still connect to my MQTT broker from another client, so not sure where it's getting stuck

uncut tapir
#

it seems to be reading lots of single 0x00 bytes from the socket in the recv_into function before it gives up

#

while waiting for the CONNACK packet I think

#

is there some sort of low level socket connection to the broker that is persisting through the soft reset that is preventing the establishment of a new working connection?

#

I restarted my MQTT broker but that didn't help

uncut tapir
#

I probably broke something because it didn't start working even after a hard reset, so I just reverted back, verified operation, and then made a get_monotonic_time function in wiz5k sockets that returns monotonic_ns if available, just like the MQTT library, we'll see how this goes

naive obsidian
#

so, from the error above, what it looks like is the MQTT client isn't closing the actual network socket when it times out, so the client needs to be closed on the timeout before trying to re-initialize it

tired coral
#

What version of MiniMQTT are you using?

uncut tapir
#

should be the latest installed from circuip/discotool for 9.0.0

#

I think my changes somehow messed up the comms, because I got the same error even after a hard reset, which normally fixed everything. So I reverted back my changes, and just replaced monotonic with monotonic_ns in wiznet5k sockets. I had used adafruit_ticks previously

tired coral
#

As of when? Today? MiniMQTT had a socket bug a week or so ago. May not be related, but just making sure.

uncut tapir
#

yeah, today

#

and yesterday

#

when I revert, I just delete and regrab the library

tired coral
#

Was the file already there? Install doesn't upgrade...

uncut tapir
#

nah, delete then install

tired coral
#

And you answered before I finished šŸ˜‰

uncut tapir
#

it's humming along with monotonic_ns for now, in a couple of hours it will pass the point where it timed out with the plain monotonic, so we'll see

tired coral
#

Trying to think of the best plan. Both wiznet5k and esp32spi should work the same, but since esp32spi is frozen on some boards, I don't want to also add ticks...

#

I've been writing up some test code and will be trying it out on a handful of boards tomorrow

uncut tapir
#

yeah, the mqtt library has a monotonic function that returns ns if available, otherwise normal

wicked elbow
#

@tired coral it may be worth looking intoā€¦ I thought the only boards that didnā€™t have long ints were the M0 boards, which means that anything with any kind of networking can use monotonic_ns ā€¦ but that could be a wrong assumption

tired coral
wicked elbow
#

A few years ago, I tried to get ESP 32 SPI to run on an M0ā€¦ I pared it all down to fit on flash, but there wasnā€™t enough memory to do anything more network-wise than the built-in get time

tired coral
#

Oh wow

#

Definitely the downside to Python and not being able to only put on it what you need

uncut tapir
#

Ugh, ran into same issue again, and this should be using monotonic_ns in wiznet, are we looking in the wrong place?

#

soft resets put me back with the same error I saw earlier

#

longer run time with longer timeout settings seems like a monotonic precision issue, but _ns should have fixed that. There's still monotonic in the wiznet5k socket_write function, but don't think we're hitting that

#

in any case, I changed that over to _ns and going to run it again. see you in 3 hours

uncut tapir
#

over 11k and counting, so we'll see if it makes it overnight

uncut tapir
#

nope, crashed at 11603s, must have been soon after I posted

tired coral
#

Crashed how?

uncut tapir
#

same as the previous message, MQTT no data received. Changing to monotonic_ns in wiznet socket seems to have removed the timeout error I was getting at first, but maybe there's a standard monotonic still hanging out in MQTT somewhere, or some other module it's interacting with

#

There's a few still in the wiznet dhcp and dns modules

uncut tapir
#

duplicated the results at work using same model of board: W5500-EVP-PICO, timeouts after ~3 hours if I don't fix the monotonics in the Wiznet socket, MQTT publishing errors after a bit longer if Wiznet is fixed.

tired coral
#

If you disconnect from mqtt and reconnect, does it still error?

wicked elbow
uncut tapir
#

I've been using 0.012 second timeout to accelerate the error, 0.1s timeout would occur after ~day-ish timescales, maybe 2. 0.012s timeout I can reliably get after 3ish hours

#

how should I disconnect from mqtt? wouldn't a soft reset do that?

tired coral
#

Yes a soft reset would. Do you still get errors after a soft reset?

uncut tapir
#

yup

#

same errors

#

they occur right away after the soft reset

#

sometimes the error occurs when I try to connect to the broker, sometimes I connect successfully, and the error occurs when I try to publish

#

if I change the MQTT socket timeout up to 0.05s, I can start to publish again here at home (it's been ~22-23 hours since the last hard reset)

#

I've changed all of the monotonics in the wiznet module to use _ns, so either there's a monotonic somewhere else that's messing things up, or the connection is really slowing down over time and it's not a precision issue, but a real timing issue

#

I'm starting to lean towards a real slow down, because if it's just a precision issue, then the timeout should only trigger when you're near a tick 'edge', and most of the time the time diff should be 0

tired coral
#

I would start printing all the timings you can. I've also seen load intensive things mess up monotonic. If I want precision time, I use a RTC

uncut tapir
#

yeah, I'm just wondering why things stop working after hours or days

uncut tapir
#

I got fooled by thinking that monotonic_ns()/1000000000 maintained precision (that's what the minimqtt library does), but it doesn't. So I've switched the wiznet library and minimqtt library over to using ticks_ms, and ticks_diff from the adafruit_ticks library. We'll see how this goes!

uncut tapir
#

looks great! I've got uptime of 4 days, monotonic time resolution of125ms, a timeout of 12ms, and it's working using adafruit_ticks for timeout checks, think I'll let it plug away for a while and maybe try a fix using monotonic_ns properly to avoid depending on the ticks library

tired coral
uncut tapir
#

yeah, now that I understand the issue I think I can duplicate success with monotonic_ns

uncut tapir
#

do we still want fallback to monotonic for boards that don't have _ns?

tired coral
#

I would say since ticks does I would. Although not sure what boards don't and if they could use this anyways. Since it's in minimqtt, it probably makes sense...

uncut tapir
#

yeah, it's not hard actually

#

already done

#

just modified their get_monotonic_time function to stay in nanosecond ints, and made a helper function to difference the nanosecond timestamps before dividing

#

modifying wiznet will be a little trickier, save that for tomorrow

Hi all.
I'm about to start on my home automation system and I am wondering what could be the main hub or central server. Some kind of small headless computing-device to host Home Assistant or similar.
These days the obvious choice might be a Raspberry Pi 5 with an SSD disk for storage, but I am wondering if there are other alternatives out there.
What I need should be running Linux, plenty of storage, decent amount of CPU power, ideally passive cooling and cheap.
Any ideas?

naive obsidian
#

basically anything "that runs Linux" would fit the bill, to be honest -- i've run HA on everything from full desktop systems to Pi 3 -- my setup is currently running HA in Docker on an Intel Celeron system, along with an MQTT broker with CPU and memory to spare, so a Pi 5 with SSD will be quite sufficient

The featherwing doublers, triplers, and quads https://www.adafruit.com/search?q=prototyping+add-on are handy if you are using feathers and featherwings, and require many points of soldering šŸ™‚ . It's also a bit tricky to make sure the headers are not tilting when you solder them in. You want to, say, put a Feather in the headers to hold them aligned.

One trick with alignment is to solder just one pin on say, a header. Then check the alignment. If necessary, reheat that single joint and move the header into alignment. Then when it cools, it will be aligned, and you can solder the rest of the pins.

With regards to IOT, if one has physical (not remote) access to an MCU (any microcontroller) it could be reprogrammed correct? Perhaps even program store read and reversed engineered correct?

I think the answer is "probably". Sometimes designs do things that would make it difficult, like not exposing pins that would be required for reprogramming, hiding components under various epoxies

There are products out there that essentially self-destruct if physically tampered with, like HSMs or bitcoin wallets

but those aren't IOT devices

yes, I finally found a few of these devices. They are High-End and create lots of manufacturing issues like bricked devices, etc. Really difficult to upgrade too.

It could be that your router is broadcasting both 2.4GHz and 5GHz on the same SSID. I've heard that esp32 devices can have a hard time dealing with these dual band routers and drop connection from time to time. If you are able, you might want to create two SSIDs on your router, one for 2.4GHz and the other for the faster 5GHz radio. You might also be able to find a cheap 2.4GHz wifi access point or router and set it up for your iot devices. But that's just a guess. If your wifi/router is single band 2.4GHz then there is something else happening to cause the disconnects...

I'd probably use an ESP32-S3 with 8+ flash. That'll give you wifi and BLE. Are you going to battery power it? The devices you linked to are usually used with another micro. I'd simplify by using a microcontroller with native BLE support.

I created a project with the ESP-32 and would like to display the sensor data on AWS-IOT. In order to indicate that the multiple devices are installed at various locations.

I attempted connecting several devices in different ways to AWS-IOT.

  1. After creating a single object with a single certificate, I created multiple objects and linked them to the initial certificate. This allowed me to view the data from a single device at a time (the object that was previously connected to the device), but now I am having trouble viewing the data from all of the devices at once, so I tried a different approach.

  2. After that, I created multiple objects with multiple sets of certificates and presented all of the device data on a single topic. I was able to view the data here, but if I had to connect 100 devices, I would need to create numerous sets of certificates, which would be laborious and challenging to keep up with. Although this solution is effective, I am searching for one that is better.

  3. I recently learned about JITP, which eliminates the need for me to create multiple certificates. We just need to create a Root CA in order to address the issue of creating multiple certificates on my own, as mentioned above. I searched the internet for a solution, but I was unable to find one that would be helpful. I am therefore hoping for advice that will be helpful.

  4. Kindly inform me if there is any more information that I can tell which would help.

  5. I also tried the 3rd step using some tutorial which is not working for me.

ISSUE STATEMENT: Establish AWS-IOT connectivity for 100 devices.

The AIO WeatherKit plus-up is fantastic. I'm using it to gather local weather data then populate AIO feeds needed to predict workshop corrosion events. It's running very reliably on an ESP32-S3 TFT Feather, experiencing > 100 hour continuous connection without any failures. Wish List: A server-side capability to feed WeatherKit local weather information directly into AIO feeds rather than retrieving and uploading from the ESP32-S3. Is that in the realm of possibility, do you think?

Hi, I dont know if this is the correct place to put this but I have tried to send a few emails but they probably get lost in the enormous amount of mail that the Adafruit support team gets. Me and my team have been working on a Pycom GPy drop-in replacement that is also a serious upgrade. The result is a module called Walter that has LTE-M, NB-IoT, WiFi, BLE and GNSS and is fully certified (CE, UKCA, FCC, IC, RCM) and thus ready for use in products. Since a few days Walter is in-stock with Crowd Supply and a webshop from The Netherlands. We are now working to get Walter in stock with other major vendors such as @celest lintel. Therefore we would need to know who to contact within the Adafruit organisation to talk about this. All info about Walter is on the Crowd Supply website: https://www.crowdsupply.com/dptechnics/walter Could anyone help me with this (maybe @night mason)? Thanks in advance!

Hi, I need help with an issue involving multiple IP addresses on a single Raspberry Pi. Iā€™m using MQTT and Node-RED with Docker to monitor and receive data from Adafruit sensors. I need the network connection between the Adafruit sensors and the Raspberry Pi to remain consistent, which requires using the TAMU_IoT Wi-Fi.

The Raspberry Pi connects well to TAMU_IoT, but when I check the IP address using hostname -I, I see multiple IP addresses listed. This wasnā€™t an issue when I was connected to TAMU_WiFi, my collegeā€™s official Wi-Fi network. However, I need only one IP address since it must be entered into the Arduino code to establish the connection. Do you have any suggestions on how to resolve this?

hoary pivot
#

or are they the IPs of the docker container networks

#

ip addr can show you the link between ip addresses and their interface, a docker container network might be named something like docker0 or br-[hex]

jade sierra
#

Im not sure, I am getting lot of addresses including wlan0 and docker0

scenic meteor
# jade sierra Im not sure, I am getting lot of addresses including wlan0 and docker0

so it's most likely the wlan0 address if you're connecting over wifi (wlan = Wireless Local Area Network), but anything beginning 169.254 is garbage / private / no-ip assigned by dhcp.
Won't be the docker0 interface, and there is one beginning br (for bridge) that has the same private network prefix as docker of 172.xx, which it usually wont be.
eth0 will be an Ethernet port on the pi (RJ45), but it has no IP assigned so it's not that.
The wlan0 interface has both ipv4 and ipv6 addresses, but simplicity usually means try the ipv4 address, which was 10.251.249.19 in the pdfs.
It may change on reconnection or after a lease period from the DHCP server (worth checking IP changed if any issues in the future).

#

If you had both Ethernet/RJ45/LAN connected and Wifi connected, both interfaces would have IPs and both should allow connection through them (at their respective IP addresses).

Thank you so much, the explanation makes sense.

I appreciate you helping me again

I'm using the Arduino IDE to create an MQTT bridge for this communication. Initially, the setup worked perfectly, but it stopped functioning after the university changed the IP address. Despite verifying that I've entered the new IP address and trying a few other troubleshooting steps, I haven't had any success.

Below, I've included the code and the Serial Monitor output from the Arduino IDE. Any suggestions would be greatly appreciated.

# pine furnace We're looking at LG which is definitely cloud connected

We have an LG set, front loaders, with cloud connection. The only annoying thing about it is it uses an "LG ThinQ" app rather than hooking up to some more universal app you might already have, at least as far as I know. I haven't actually looked into seeing if I could add them to another app. That said, the cloud connection is handy as it will alert you when your washer or dryer has completed a cycle, will alert you if there is a problem (such as stopping due to an imbalanced load), and will tell you when things are due (washing filters out, running a tub clean cycle, etc.). You can also download other wash cycles although you can only have one in use at a time, however I have found most of the built in cycles cover most uses. As I said, notification are handy if you are are a tight schedule and are trying to, for example, quickly wash and dry something to wear or pack and you get distracted around the house where you would forget to move it from washer to dryer or don't notice is stopped on an error 20 minutes ago.

#

Oh one other handy thing is in the app you can turn on the setting so the washer and dryer talk to each other. So when you use the, for example, bedding cycle on the washer, when you move the bedding over to the dryer and turn it on, it will automatically pick the "bedding" setting on the dryer. A minor thing but still kind of cool.

pine furnace

# pine furnace Awesome! I think we're sold on it. Just gotta figure out how to give away our ex...

Oh one more feature I love, which has nothing to do with cloud connection. We bought the models with the steam feature which can be used on both the washer and dryer for certain functions like sanitizing, but the one I love is the drier has a steam setting for when you quickly need to dewrinkle something and don't have time or simply don't want to iron. It is 10 minutes and you can throw a shirt or a pair of pants in there (or both) and in ten minutes is will steam out the wrinkles so long as you pull them out right after it is done and don't let them sit and re-wrinkle. I have used it when I discover the shirt or pants I wanted to wear look like they have been crumbled into a tight ball for a week. Throw it in the dryer, go take my shower, and they are ready when I get out of the shower. Of course the app will remind you to get them out (had to bring this back around to "iot" to keep on topic).

hollow dust
#

I like our LG set - but for one annoying bug. About 30% of the time the washer won't turn on unless I unplug it for a bit then plug it back in. Often, when this happens, I have to do it a few times. LG support says they will not dispatch a repair crew for intermittent issues.

Adafruit IO send_group_data() from Python?

Goal: send a voltage value and a current value in a single API call

In some of the documentation (https://io.adafruit.com/api/docs/?python#create-group-data) there is some detail about group data.

There is CirCuitPython doc for send_group_data() (https://docs.circuitpython.org/projects/adafruitio/en/stable/api.html#adafruit_io.adafruit_io.IO_HTTP)

  • Is this capability not available from Python?
  • Is there an alternative method for a sending data to a Group or a method of performing a single 'send' of data to multiple feeds from Python?
scenic meteor
# glad helm **Adafruit IO send_group_data() from Python?** Goal: send a voltage value and a...

Great question, the python library doesn't have such a thing built in yet, but it's possible to use the _post call and supply your data as a custom list with feed keys included.

This is because most of the methods use Data model for a single feed so there is no feed_key field/property.

In theory you can use the Groups endpoint to send both feeds at once, but the python library specifically doesn't support that. We could expand the models to have such support though!

Instead you could make your own list of data-model-like objects (to represent the API data for this endpoint: https://io.adafruit.com/api/docs/#create-multiple-data-records ) and pass that along with the URL to the _post call, similarly to how the library does it's data sending.

Also you will probably be better off asking such things in the #help-with-wippersnapper-and-adafruitio channel ā¤ļø

Okay, just confirmed with Postman that it does at least work, although I had forgotten how the data looked for posting to groups/GROUPNAME/data. It's a dictionary with a feeds collection, each item with key/value fields. Then the main object can have created_at / location too.
In theory calling _post with path arg as "groups/group1/data" and then data arg as

    "feeds": [
        {
            "key": "feed1-in-group1",
            "value": 0
        },
        {
            "key": "feed2-in-group1",
            "value": 100
        }
    ],
    "location": {
        "lat": 52,
        "lon": -2
    }
}

This assumes the IO python client already has the IO username + key set internally (self.key)

Feeds graph does not match table data
This may be a bug, and if so, would someone tell me where to report it.

2 days ago, I had a glitch in my code. I fixed my code, deleted the data anomalies from my feed, and restarted my code.

The table data has valid data. There is a gap in the data (as expected).

2025/05/27 12:58:04PM    2.728
2025/05/27 09:49:52AM    2.709

However, the feed graph shows a value of 2.77 at 12:30PM

Is this the feed graph on feed pages as opposed to graphs on the dashboard pages?
This is unfortunately a known issue, related to the backend storage system and what we get charged for, basically the graphs are using heavily cached data.
You can request an individual feed be regenerated via the support / feedback option on IO pages. I can't quite remember if they self-heal eventually...

glad helm
scenic meteor
glad helm
# scenic meteor ooh that's curious, what do you mean by the graph was correct but with the erron...

Steps:

  • code generated some bad values which were subsequently uploaded to AIO
  • stopped code
  • deleted bad data from AIO (at this point, the table data and the graph agreed)
  • fixed my code
  • restarted my code and verified new values uploaded to AIO were correct (both table and graph agreed)

Sometime later I noticed there was a spike on my graph and it coincided with the last erroneous value I had deleted.

Now that erroneous data shows in the graph but not the table.

scenic meteor
#

so at/before step 3 (deleted bad data), before that delete you say the graph and table agreed, so surely would have shown the spike? Then after delete (still step 3) the table would be updated but not the graph, or at least that's what I would expect to see

glad helm
#

Before deleting data, the table and graph agreed and the spike was present.

Immediately after deleting data, the table and graph agreed and the spike was gone.

After my corrected code resumed, the table and graph started receiving new data. The table was correct but the graph had the spike.

#

.
It's as if the graph was not displaying the last value I deleted but the graph still had that value cached. Once the feed received new data, the graph appended the new data and the spike point was visible.

scenic meteor
#

oh interesting, almost like the javascript graph code dropped the datapoint, then when getting the new data / whole feed data it then got the bad point back

glad helm
#

Either way, I was expecting the graph to match the table.

If there is caching, then ...

  1. The graph caching should be documented
  2. The coaching should be refreshed eventually (also documented)
#

FYI: the dashboard has the same erroneous spike.

scenic meteor
#

Yeah agreed, as a user it's very unclear and unexpected. Fire off an email highlighting the issue / desired resolutions, it won't be immediately fixed, but it's more ammo for the issue (about regenerating feed graphs)

#

(I've been told a couple of times it's not an issue very often, so hearing from users that it is an issue is useful even if it doesn't feel like it)

glad helm

I don't see a way (on my AIO page) to report the issue

It turns out there is a "generated" version of the feed data that is different from the table entries.

I received an email on my issue and the proposed resolution is for someone to go in and manually rebuild the interpretive graph data.

Given this happens on nearly every feed I create, I don't see this as a sustainable solution.

If the feed graph data has the possibility of getting out of sync with the feed table data, I suggested a button or menu option to trigger a resync. Even if the resync needs to be scheduled and handled asynchronously, the process should be under user control and not burden a support person.

personally, I have just run an experimental setup for a few weeks a couple of years ago. Since that I've done one test setup to see compatibility with Adafruit IO.
This week I've obtained some IKEA matter/thread devices, and have some existing 3rd party (app/api) switches etc which I use via google home (no HA), so I'm planning to setup HA again for the matter integration once my sonoff dongle-E arrives as I don't have an existing thread compatible apple/google/amazon/HA hub (zigbee/thread coordinator), and I've been keeping a close eye on the updates as their (nabuCasa/HomeAssistant/OpenHomeFoundation) voice assistant and new products and firmware releases (with matter certification) have come along. I'm also half keeping an eye on related tasmota and esphome things, both with a view to Adafruit IO compatibility and generally, so these days it's a no brainer to connect those to home assistant rather than anything else.

AIO line graph of Lat and Lon values

I am sure this is a case of "why would you want to do that?" but it appears the line graph block is fixed to only graph the feed value.
I would like to graph the changes in Lat and Lon.
Ideally, I'd like all of the feedback data to be graphable and ideally as a multi-line graph.

Full disclosure: My reason for this is to store non-positional data in the metadata fields as it is easier and uses less overall storage to treat those other fields an nothing more than just numeric data vs using multiple feeds for the related data.

For now, I have stopped using dashboards and just watch the feed data directly.

Hello! I'm currently researching how to make a project that involves a fairly high-quality video stream via wifi (I want to look at an outdoor location, from an indoor location) and I was looking at different hardware options:

  1. raspberry pi + gopro (there is an api for gopro wifi, but I haven't tried it myself yet) ex. https://www.hackster.io/estefanniegg/automated-gps-controlled-photo-taker-3fc84c , see https://github.com/KonradIT/gopro-py-api/blob/master/README.md
  2. raspberry pi + raspberry pi camera module (seems easy to implement?) see https://projects.raspberrypi.org/en/projects/getting-started-with-picamera
  3. particle photon / adafruit feather ?
    In the longer run, I also want to run the video through an image processing python script, to detect X number of certain objects that come into frame, and I'm not sure how that can be incorporated into the stream of data.
    This will be my first IoT project, so any advice would be much appreciated. Thanks!

#

the disappointing part of the GoPro is that you have to use WiFi. They won't give you the stream over USB

#

for object detection you'll probably want a Pi4. I don't think any of the Particle or Feather boards can keep up at high resolution

#

a USB webcam might be worth considering. The better ones provide h264 streams natively. That makes your processing more intensive though.

severe socket
icy magnet
#

@glass bridge can I only get the stream for object detection through USB on a Pi4?

#

@severe socket so regardless of the camera I pick, do you think I should get a Pi4? @glass bridge

glass bridge
#

Nah, I'm sure you can use pretty much any scheme to get the video stream. The GoPros only allowing WiFi means that you can't use WiFi to connect the Pi to the internet without adding a USB WiFi dongle.

severe socket
#

@icy magnet Sure - it's a good single-board-computer and well priced. Unless you can swing for a Jetson Nano or something similar.

glass bridge
#

Video analysis is computationally hard so you'll want as much power as you can conveniently get to throw at it.

white junco
#

You could always plug a Movidius Neural Compute Stick into a Pi.

glass bridge
#

I did run into some dropped USB packet issues when I was streaming from a Pi3 a couple months ago, which may weigh against the USB webcam on an older Pi. The Pi4 has a new USB controller so hopefully it doesn't suffer the same issues

white junco
#

If I had a Pi 4 available, I'd try it with my fancy webcam

icy magnet
#

Got it thanks!

#

@glass bridge why can't I use wifi to connect the pi to the internet if the gopros only allow wifi?

glass bridge
#

because you have to use the wifi to connect directly to the gopro

white junco
#

There is a way to get the video stream from the pixy2 (the software will let you monitor it on your host computer while you dial in the settings), but I don't know how it works. It can do its own object detection (colors and symbols) as well.

glass bridge
#

the pixy2 looks like it'll do some object detection for you. You can get frames from it that you can probably run through opencv for your own detection

#

you probably want to consider what sort of lensing you might need to get the shot you want too

icy magnet
#

Ah thank you

#

Do you think that the esp32 would have enough processing power to run object detection?

severe socket
#

It can do it with ESPCAM

severe socket
icy magnet
#

What do you think about using an IP webcam, and running the object detection on a remote computer? Rather than having a raspberry pi with a camera run the object detection, and stream the video and data from the object detection, onto the remote computer

I have heard some people say that a solar-rechargeable battery works, but other people say no, 2) do you have experience getting the video stream and using it for your own scripts (maybe through RTSP or IFTTT)? Thank you so much!

@icy magnet hey mate first things first, I've noticed you pasted this question in several topics, if you could make up your mind where you would like to be replied I'll post it there

The ESP32 can't run object detection and would already be struggling hard with keeping a decent fps going

#

and top that off with that fact you want to run it on battery power... I think you need to look at your hardware setup and weigh out some of your nice-to-haves with needs

Anybody here actually using the ESP32 cam? I'm wondering what kind of FPS can it achieve

Hi, Iā€™ve been bugging the forum and adafruit.io previous about the webhooks. However my problem is receiving a cut-off json through mqtt in uart mode (circuit playground express + bluefruit le). anybody has run into this limitation issue before?

white junco
#

I'm not sure it would fit. Generally when I want a tiny wifi device with a low pin count, I grab an Electric Imp or the usual inexpensive 8-pin ESP8266 board.

#

The Electric Imp is very cute (looks just like an SD card), but a little strange to configure using a flashing screen to send data to it optically, and not as cost effective as a Trinket or ESP8266.

white junco
#

Seeedstudio has 'em, but they want $30 apiece (plus shipping), which seems fairly high.

#

I haven't tried reflashing one of those boards, but I've heard people having issues with them.

Same here. I'm pretty sure I fried one, but I never got one to work right. I did get the Electric Imp to work, but never did much with it.

My guess is that the cables are propagating signals inside. You might try winding the cables around some ferrites, but for real isolation, you might need either a USB isolator, or filtered feedthroughs.

If that doesn't help, you may want to look for some copper foil (you can get stuff like copper flashing from home improvement stores)

I'm on the right track though, right? I feel like I'm missing something, but AFAIK, it's just wrap and optionally tie to ground. A real faraday box/cage/shield would be better, but time is currently my enemy...

I had an opportunity to buy a shield room at auction once. $50 for an 8x8x8 foot cube with 2-inch thick walls filled with honeycombed copper, and including fingerstock door seals and an RF tight cable feedthrough. Probably cost a fortune (over $100k) when new. Alas, I didn't have access to a truck to move it.

@chrome sapphire you can try bypassing your power supply wires to ground with caps... .1 uf might be enoughā€”@white junco can probably give you better values. use twisted pair for any connection wires with one wire going to ground on one side onlyā€”or use small coaxial cable. RG-174 is small and inexpensive, but may not have shielding adequate to the frequeny youā€™re trying to block. there are feedthrough caps made especially for bypassing power and signal lines into cabinets or enclosures that need to be rf tight. an asideā€”i once worked at a 50kw am station and spent most of my shift inside a faraday cage! the rf density outside the shielded room was so high that you could be burned by picking up a pair of needle-nose pliers! ā€” anyway, some random thoughts on what might help you.

Morning, I'm wondering if anyone has run into this issue before. I'm writing functions for formatting messages that are going to be published to my mqtt broker. I keep getting core panics and I've narrowed it down to an sprintf line. I'm trying to convert an integer to a char * and it's causing the panic. Removing the sprintf line and setting formattedMessage to a string like hi works without issue

šŸ“Ž Screen_Shot_2020-02-13_at_11.36.45_AM.png
#

is there an issue with sprintf? is this even the best way of converting (I'm not ultra versed with c)?

#

me == perplexed šŸ˜

eternal crest
#

well, I figured it out. I didn't realize that the pub/sub library's publish method requires const char * strings and not char * strings. I don't 100% understand the distinction, but once I made sure I was passing the correct types of string pointers and figured out how to pull those string pointers out of String objects it worked.

šŸ“Ž Screen_Shot_2020-02-13_at_12.20.34_PM.png
trail pagoda
#

To explain your original panic, you were creating a pointer variable for formattedMessage, but didn't have any memory that it pointed to, so sprintf() was just writing somewhere random in memory, causing the panic.

#

The right way to do that would have been to declare a char array of an adequate length, and pass a pointer to that array to snprintf().

eternal crest
#

ahh! thanks for the explanation. Restating it so I make sure I understand:
char * varname creates a pointer, but without initializing it to anything the pointer doesn't actually grab memory b/c it doesn't know how much memory it's going to need, so to actually reserve memory (I know that's not right term, just trying to conceptualize it) I can char varname[xx] so that I get the character array pointer AND have specific addresses in memory reserved for the array, right?

#

and that pointer with the array can be used for sprintf

trail pagoda
#

Exactly right! šŸ’Æ

#

Note that declaring a char array in a function will reserve temporary memory on the stack, just while the function is running, so if you need the data to be persistent for the length of the program, that's what malloc() is for.

eternal crest
#

awesome, thanks for that explanation šŸ˜„ That's def a good insight to have in understanding how pointers work and are handled

#

cool. re: malloc, is that similar to using new to grab memory from the heap?

trail pagoda
#

Yep! Under the hood, new is basically calling malloc to get the memory and then initializing the object too.

eternal crest
#

ah another good to know šŸ™‚

#

thanks! hitting these little snags and debugging them and getting explanations like this def makes me feel like I'm groking the language more

It should be able to talk to any Bluetooth Low Energy peripheral, but not Bluetooth Classic devices. Probably the camera trigger will be BLE, so you're okay from a hardware perspective. Software library support is probably okay but may not be fully plug-and-play depending on the specific device.

I'm still fairly new to Discord, so I'm not sure if I'm going about this the right way, but I'm trying to connect Discord to Node-Red so I can make my IOT connected wearables respond to Discord messages. As far as I can tell, I need to create a Discord bot to get Node-Red to receive Discord messages. However, I can only add my bot to servers where I have administrator permission. I created a test Discord server and added the bot (named BrightWearables), and it works well there, but can't see messages on other servers. Would I be allowed to add a bot that does nothing more than read messages from the Adafruit server? I thought it would be fun to create a project which responds to Discord messages, and demonstrate it on Adafruit Show and Tell, so it could respond to messages in the #live-broadcast-chat channel in real time.

Might not be the spot for it, but I'm curious as to how cloud cameras work, especially Wyze. Do they use WebRTC or something you reckon, to get peer-to-peer connectivity from the smartphone app to the camera, or do they just push everything to a cloud server? In which case how do they afford to do that when they don't charge monthly fees? I was thinking for mine to use WebRTC to establish a direct connection between app and device, and rely on STUN and TURN servers for NAT traversal as needed. TURN would involve a running server so it would be used as a last resort if NAT/firewall policies prevent all inbound communication to both phone and device. I could also just setup a reverse SSH but that doesn't seem as professional.

#

And if device/phone are on the same LAN it'd just direct connect

wicked elbow
#

@jade surge Wyze uses AWS to keep a 14-day history. Typically when a service is "free", you are paying with your data. You can have your attorney attempt to interpret their privacy policy šŸ˜‰ https://wyze.com/privacy-statement

#

highlights include: "We also obtain information about you from other sources." & "...Personalize your online experience and the advertisements you see when you use our Devices or Services or third-party platforms based on your preferences, interests, and browsing and purchasing behavior..."

#

Other than that, looks like they have SD Card or WiFi access.

jade surge
#

Yeah I knew they used AWS to some extent, I just didn't know if ALL streams went through AWS

#

in which case they are paying for that bandwidth

#

Cheap devices and no monthly fee, of course there's a catch šŸ˜‰

#

I want to make my own IoT device that has a camera as a secondary feature and have that camera accessible anywhere but not pay out the nose for it

#

I've already made a device and an app, now is just the video streaming bits

white junco
#

Unless they're using your network, in which case you're paying for the bandwidth.

jade surge
#

Right, either they stream everything via the AWS server or they use some P2P technoloy like WebRTC and the AWS is only used when no NAT traversal can be done. I'm trying to do the latter, was just curious how the big boys did it

#

Nest doesn't charge for streaming either only recording, so I imagine they must do something similar or they just eat the cost of streaming, which makes more sense for them because of the high per device cost vs a company like Wyze

Ooffda. Thatā€™s a lot of steps that have to be done exactly right. I played around with it when it first came out, and the security was a pain. Looks like it still is. I kinda gave up on it. I would try looking for logs on amazon. There should be some. And you should be able to watch the MQTT messages that get sent, to see if they get there. Do you need the power and complexity of amazon, or could you use Adafruit IO. I found it much easier to work with.

lucid flame
#

@near garnet - no experience with AWS, but I've been working on getting Azure IoT Hub and IoT Central working with CircuitPython, so if you need the power/complexity of a major cloud IoT platform and can switch to Azure I can help. The libraries for it are going through a PR/testing phase now and will hopefully be available in a few days in the Adafruit CIrcuitPython Bundle.

near garnet
#

@lucid flame What's the short pitch for Azure's IoT offering? The draw of AWS' for me is: MQTT pub/sub relationships, rules triggering on publish, and device "shadows" (states-as-seen-by-cloud) that allow devices to drop connectivity for lengthy periods of time and recover

#

@severe wing I got it working (and submitted doc change requests to clarify the problems I had)! Then I did something unfortunate to my ESP32 and haven't had time to fix it. :(

And unfortunately, yeah, I want publish and subscribe and rules execution, which is a bit further than AdafruitIO can get me.

Yea, you are right sounds like you needed this direction . Thatā€™s great you got it working. Was there a ā€œgotchaā€?

#

The whole GUI (on AWS' end) has changed since the docs were written and there are 3 certs (AWS root CA, device pub key, device priv key) while the docs only mention two. I believe I only needed the device public and private keys, but the docs were pretty unclear. Oh, and the docs ask for a "destination" which needs to be your AWS Thing endpoint with the protocol (https://), which caused me quite a bit of grief

NOTE FOR FULL TRANSPARENCY - I work for Microsoft, and my role is to help makers, students and teachers be successful with Microsoft products, especially with IoT.

Azure has 2 offerings - IoT Hub and IoT Central and they can both work over HTTPS, MQTT and AMQP.

Azure IoT hub (https://azure.microsoft.com/services/iot-hub) is a lower-level pipeline for IoT events in both directions, so you can send messages from the device to the cloud over MQTT, send messages from the cloud to device, send requests to invoke methods on the device to tell the device to do something, and devices have a twin that can be updated by the cloud and device and synced when you connect, which is essentially the same as an AWS device shadow. You can connect IoT Hub to a host of other Azure services that react to messages to analyze data, store it, do AI, whatever. The more advanced IoT Hub SDKs allow you to even update device firmware via the cloud.

Azure IoT Central (https://azure.microsoft.com/services/iot-central) is a software-as-a-service platform that sits on top of IoT Hub, so you can define what devices can do, create dashboards and other visualizations, set up rules and connect the data to other Azure services as needed. IoT Central allows you to send telemetry from the device, sync properties between the device and the cloud, and invoke commands on the device to tell the device to do something. You can even connect no-code apps such as Azure logic apps to IoT Central to control devices (I have a busy light linked to my calendar for example)

#

We have official Microsoft supported device SDKs for C, .NET, Python, Java, JavaScript, iOS and Android, and I've been working to update the CircuitPython SDK from Adafruit to use MQTT and fully support IoT Hub and IoT Central. It's an 'unofficial' community SDK supported by me and a few engineers from Microsoft who build the CPython Azure IoT SDKs, not managed and controlled by Microsoft but we are looking at the interest in official CircuitPython support, and if there is enough interest we will bring it back in-house and maintain it officially.

#

BTW - your issue about having the protocol at the start of the AWS Things endpoint. How recent is your MiniMQTT as there was a bug introduced recently that made this necessary, even for MQTT endpoints. https://github.com/adafruit/Adafruit_CircuitPython_MiniMQTT/issues/25

#

It was exactly that error, actually! I believe MiniMQTT is a transitive dependency for my circuitPython setup, so I don't think it'd be easy to version bump alone.

#

And that's good to know - I'll definitely give Azure's IOT offering a try soon & tell you how it goes. I'm mostly on AWS out of familiarity, so am keen to try a few different providers out.

lucid flame
#

Yeah - the AWS library uses it. The changes that introduced that bug are breaking, so might break the AWS libs if you roll back to an earlier version. I've been adding https at the start of my library as a workaround till the issue is fixed - which is fun when the broker name is retrieved from another service, so I have to try to connect, and if I get an error, retry with https on the start.

#

IoT Central is probably the best place to start as its got a nice GUI to see the data, whereas Hub is just and endpoint for data. It's not the simplest to set up as it's designed to scale for enterprise use, but it's not too complex. It's also free for up to 2 devices with an Azure subscription, or free for 7 days without one. Hub has a free tier for up to 8,000 messages a day and for that you need an Azure subscription. Free is always good when playing with new toys!

#

Yeah! I expect I'll get to playing with it in the next week or so. Is it ok if I reach out to you then w/ architectural, troubleshooting questions?

Of course! Either here or email me at first dot last at Microsoft dot com.

lucid flame

Or via an IoT service

#

@lucid flame - so if I am starting out with a simple CircuitPython project that I hope to scale (basic monitoring, and some centrally pushed status notifications) - these seem to fall into the IoT central "Tier 2" concept, however for my dev case of one device, it will be free it seems.... do I also need to create and manage an IoT Hub myself in the Azure portal?

Also, the https://learn.adafruit.com/using-microsoft-azure-iot-with-circuitpython/microsoft-azure-setup example pretty much road blocks instantly, as the command "az iot hub generate-sas-token --hub-name <azure-hub-name>" chokes :(

Is there a better / more complete example of using IoT Central with CircuitPython you can point me at?

Do you know if i can sell product arduino based?
btw can I use for example adafruit libraries in my products?
Any recommendation about where to get CE certifications to launch an IOT product based on Raspberry pi, Arduino or both is possible in Europe?

@dim agate - we (Microsoft) have been working on updating the Adafruit IoT library to support both of our IoT offerings, Hub and Central. Currently we have an open PR to update the Adafruit Azure library based on the code that Elena (who wrote that post) and I worked on. We are trying to gauge the demand to see if we should create 'official' support in our core libraries fully published and maintained by Microsoft rather than maintained by a few enthusiasts.

#

@sullen field - those docs on learn.adafruit.com are a little out of date. I'm waiting to get access so I can update them all, as well as create content for using Central/Hub with CircuitPython.

#

IoT Hub is a raw pipe - so data in and out, messages to/from devices, request devices do things, sync a 'device twin' so a JSON document of values between the device and the hub. You can then connect the pipe to other services to do whatever.

#

IoT Central is a software as a service platform that sits on top of Hub, and gives dashboards to view data and a more simple way to talk to the device. Again, you can connect it to other services

#

For IoT Central, I created a nice walkthrough for a plant monitor here: https://aka.ms/agrohack

As an Azure IoT consultant, I say "YES PLEASE" to official Azure IoT support for CP. It is a very robust set of boards, libraries, and community. Very rich set of tools to get proof of concepts and certain size production deployments going.

It doesn't support stuff like firmware updates or IoT Edge

Great, I look forward to it. Despite having almost 10K in AWS credit available, their codebase just makes me want to shoot myself, so I am happy to go out of pocket for Azure as the basis of the kickstarter projects I am bringing out later this year. MS really needs to step up it's maker outreach though or AWS will own this space sadly.

@sullen field we are working on maker outreach! https://www.instagram.com/p/B-s6sKMDdPt/?igshid=1cevo0bvud38b. As for giving out credits, we only have free trials and free tiers of services (for example IoT Hub is free for 8,000 messages a day, IoT Central is free for up to 2 devices), and for organized events we can sometimes bring passes to give credits for 30 days or so. No idea if we have other programs in the works. But it's true that the winners can sometimes be solely because they gave out the most money to folks.
