So that basically makes any kind of public dashboard with inputs useless

viral stratus Dec 15, 2017, 11:08 PM

#

Recently I found another option, not a drop-in replacement but another tool to use, one sec

torn moss Dec 15, 2017, 11:08 PM

#

So far, and it could be a function of how the MQTT broker is configured. Don't know, never done that.

viral stratus Dec 15, 2017, 11:08 PM

https://www.pythonanywhere.com/

#

This is one of a number of sites that does small webapp hosting with a python console

mighty fossil Dec 15, 2017, 11:08 PM

#

That's frustrating. I've got a trophy I made that has a neopixel ring in it that I want the whole group to be able to control

viral stratus Dec 15, 2017, 11:08 PM

#

In theory, you could import MQTT stuff and connect it to AIO that way, and create a webapp frontend

#

The free tier is enough to fool around with and run one project

mighty fossil Dec 15, 2017, 11:10 PM

#

Oops, I forgot, cursing isn't allowed.

torn moss Dec 15, 2017, 11:10 PM

#

well, dinners ready!

mighty fossil Dec 15, 2017, 11:10 PM

#

@viral stratus I know I was using a node app I made to push to AIO

#

I wonder how hard it would be to duplicate and pass the color info to the feeds

#

Can Color Pickers "recieve" data?

stray delta Dec 15, 2017, 11:13 PM

#

jumping in late. i believe with MQTT + REST API, you can include your AIO key in the urls which will feed data. not secure obviously, but gets around passing out credentials and all that business.

mighty fossil Dec 15, 2017, 11:13 PM

#

I mean I could technically do that in a node backend that would obscure the AIO key

#

Still at that point seems easier to try and interface directly with the feeds. I'm not familiar with MQTT setup.

#

@stray delta you always seem to be helping me on my projects 😛

stray delta Dec 15, 2017, 11:14 PM

#

haha. we just swim in similar lanes, i guess.

mighty fossil Dec 15, 2017, 11:14 PM

#

(The good news is, my current project is almost done)

#

Looks like I can indeed write this using node. This might be the better option.

mighty fossil Dec 16, 2017, 12:48 AM

#

@stray delta do you know if you can use REST POST to button feeds?

mighty fossil Dec 16, 2017, 1:09 AM

#

Anyone possibly able to help me with AIO and REST issue

mighty fossil Dec 16, 2017, 3:59 AM

#

Nevermind, was a node issue. Thanks!

Anyone have experience using the Adafruit_MQTT library with the Wifi101 library on the FeatherM0 ATWinc1500 board?

#

It used WiFi101 just fine until I add in MQTT. Then nothing wifi works 😦 I haven't been able to find information on that combination.

stray delta Dec 17, 2017, 4:38 PM

#

@woeful tinsel this forum thread reports it working (related to the example using the deprecated Winc1500 library vs the WiFi101 library)

@stray delta Yeah. My S&T project is now functionally complete.

Beyond S&T it's a prototype of part of my next generation smarthome edgenode

mighty fossil Dec 18, 2017, 4:18 PM

#

Is using REST in 3rd party apps (Node app in my case) the best way to expose feeds to be influenced outside a dashboard (ie: publically?)

torn moss Dec 18, 2017, 6:09 PM

#

Not sure, and not investigating since my ousidr feeds where the controld to a gas burner, so there needed to be a bunch of 'security' around that anyway. Sorry.

#

FYI, issues around data rate, groups, 'ghost feeds' , etc have been fixed, and there may be a possible adafruit blog post coming out about it.

mighty fossil Dec 18, 2017, 6:15 PM

#

@torn moss no worries, its basically the only thing I've been using for outside input. I just wanted to make sure I wasn't missing something wildly

novel ember Dec 19, 2017, 8:31 PM

#

@mighty fossil real short answer is: yes, the HTTP API is the easiest way to expose your feeds to the public. It's worth noting that data usage is accounted to your account, since it'll use your API keys.

#

I published a demo app awhile ago and just updated it with caching to account for data usage: https://github.com/abachman/adafruit-io-shared-client

GitHub

abachman/adafruit-io-shared-client

Contribute to adafruit-io-shared-client development by creating an account on GitHub.

#

it's live on Heroku at https://desolate-peak-89727.herokuapp.com/

#

and the public dashboard is at: https://io.adafruit.com/abachman/dashboards/io-shared-client-demo

Adafruit IO

Adafruit IO is the easiest way to get your projects onto the Internet of Things!

#

the tricky part of cross-account publishing is accounting for rate limits

#

if we count it against the feed owner, that allows for denial-of-service style attacks

#

if we count it against the publisher that allows for the possibility of opening a large number of extra accounts (which isn't something we police heavily) to push data to a single feed

#

and if we allowed anonymous publishing then the rate limits are kind of meaningless since it would mean you only need an account to create the feeds but nothing to interact with them

#

the solution is probably in the balance of those three scenarios

crude perch Dec 25, 2017, 1:39 PM

steady rapids Dec 29, 2017, 5:57 PM

#

I'm thinking about making a fork/PR for the IO & MQTT libraries to give it an option to block less. Trying to reduce how much time is spent in io.run(busywait_ms), since I need to do other stuff frequently in the loop(). Tried passing in 0, but that blocks for 100ms, value of 1ms is better, but still not ideal. Also the part that blocks until connected basically means my whole program is dead when the internet blips. Anyone else run in to this and have workarounds?

stray delta Dec 29, 2017, 7:10 PM

#

@steady rapids I ran into something similar when I needed to keep cycle time short and predictable. Here is how I worked around it:

 /* io.run() was causing the loop to take 100+ms per cycle, since its timeout defaults to 100ms.
   * this loop needs a higher cycle rate (lower cycle time) to reach an acceptable fidelity of
   * sensor readings. io.run() does allow the timeout to be set during the function call, which
   * can really reduce the cycle time. however, io.run() calls for subscription updates every
   * time it is run. in an effort to both reduce cycle time by using a shorter timeout and practice
   * good AIO etiquitte, I decided to reduce the amount of times io.run() is called while using the
   * shorter timeout. A 15ms timeout works well enough for my datapoints, but obviously won't work for
   * every situation (pings worked at 5ms, but feeds got chopped sometimes). 
   */
  if (currMillis - iorunMillis >= 5000) {
    io.run(15);
    iorunMillis = currMillis;
  }

steady rapids Dec 29, 2017, 7:53 PM

@stray delta , thanks, thats a good idea.

spring bolt Jan 2, 2018, 3:04 AM

#

I'm curious. Why does the Adafruit IO python library take so long to load in a Python program on my Pi? Is there a way to alleviate this?

tired marsh Jan 3, 2018, 7:11 PM

#

@spring bolt How long does it take?

#

Mine only takes a couple seconds, and I'm just using the original Pi. Could it be your internet ping?

spring bolt Jan 3, 2018, 7:26 PM

#

It's the import statement, Pi Zero W. Takes about 30 seconds to a minute

#

Connecting to AIO is fairly quick

stray delta Jan 3, 2018, 10:29 PM

#

@spring bolt I briefly looked at it the other day when you asked. the init.py imports every file in the library, and the others import some more. MQTT library is like 24/34 KB, so shouldn't be a transfer issue on a Pi. although, it could depend on how your directories are linked and ordered. Is the long load inside a project with other stuff, or also when just by itself in a script (deductive reasoning...)?

spring bolt Jan 3, 2018, 10:30 PM

#

It's when importing the library at all.

#

Can go into the python REPL and type "Import Adafruit_IO" and it takes a while

stray delta Jan 3, 2018, 10:37 PM

#

hmm... remove and re-pip?

spring bolt Jan 3, 2018, 10:38 PM

#

@stray delta I've had to reinstall it (And the OS...) a handful of times while working on the project.

#

It's not a huge bother, but it does take a while

@keen dirge I never remember seeing any values in that column. But, went and checked and it looks like only text/string values will show up on the feeds page... All the empty ones are number based.

@stray delta Thanks - I thought I recalled seeing it filled in sometime in tha past, but it was quite a long time ago. It's not big deal, but would ne nice to have them visable at a glance.

#

ahhhhhh, yeah, super been bugging me too. We changed/restyled the way the feed list worked when we launched IO+ and haven't been back to it, but we've fixed it finally.

#

(thanks for the nudge @keen dirge & @stray delta)

#

you should see live "Last Value" data for all feeds in the main group+feed list and on each groups' respective pages

Had an issue today that made me delay adding IO to the door opener project we just published. Perhaps I missed something

ivory wraith Jan 13, 2018, 12:40 AM

#

Thank @shut kiln

#

I need to respond to local http calls (from the users devices) and I’d also like to be connected to IO

#

But if I setup with the WIFI101 library I can’t also connect via IO

#

Is there a way to tell IO to use the existing WiFi connection?

stray delta Jan 13, 2018, 1:12 AM

#

@ivory wraith are you using the AIO library, or the MQTT?

ivory wraith Jan 13, 2018, 1:14 AM

#

I was trying the aio. But I’m flexible

stray delta Jan 13, 2018, 1:15 AM

#

just making sure how to respond. replace while(io.status() < AIO_CONNECTED) with while(io.status() < AIO_NET_CONNECTED). a couple of us discovered this "flaw" (hardly a flaw really) a little while ago.

#

there is an open issue for it: https://github.com/adafruit/Adafruit_IO_Arduino/pull/19

ivory wraith Jan 13, 2018, 1:16 AM

#

The connection stuff asks for a SSID/pwd

#

Is there a constructor that takes a WiFi connection?

#

I might have missed it

#

Or can I get the WiFi connection from it?

stray delta Jan 13, 2018, 1:17 AM

#

ohhhh...hmm. i'd have to look into that scenario. should be surmountable. but, the MQTT might actually be easier. the AIO library is just an all-in-one sort of wrapper.

ivory wraith Jan 13, 2018, 1:18 AM

#

Ideally I can use the atmel provisioning

#

I could make straight test calls right?

#

Let’s jump to my end goal

stray delta Jan 13, 2018, 1:19 AM

#

well, you can use the existing. just don't call the io.connect() and start with while(io.status() < AIO_NET_CONNECTED)

#

but, if the wifi goes down, then io.run is going to try and reconnect...

ivory wraith Jan 13, 2018, 1:20 AM

#

I want WiFi provisioning that remembers SSID and pwd the wifi101 has that (kinda buggy)

#

And I want to be able to listen to port 80 directlu

stray delta Jan 13, 2018, 1:21 AM

#

port 80 for incoming, yes?

ivory wraith Jan 13, 2018, 1:21 AM

#

So right now I use the WiFi beginProvisioning() call

#

And it kinda works

#

I have a connection that I can use

#

Yes

#

I want to receive calls from adafruit io

stray delta Jan 13, 2018, 1:22 AM

#

honestly, using the MQTT library would be better for you talks to AIO. you don't need the additional wifi stuff...

ivory wraith Jan 13, 2018, 1:22 AM

#

I am behind a firewall so aio seemed to be the right choice

stray delta Jan 13, 2018, 1:22 AM

#

the additional stuff in the AIO library, i mean

ivory wraith Jan 13, 2018, 1:22 AM

#

Can MQTT connect from private iOS?

#

Ie begins a firewall?

stray delta Jan 13, 2018, 1:23 AM

#

there may be an MQTT app. I know there is one for android...

#

let me make sure i understand the goal: Kyliegh's iPad talks to Feather, Feather moves motor, Feather updates AIO with current position/last movement, Feather also listens to AIO for commands. I think that's what you said in the video last night.

#

or wait. was it Kyliegh's iPad talks to AIO?

ivory wraith Jan 13, 2018, 1:27 AM

#

The first one

#

Feather has to take local http calls

#

From the same (private) IO neteork

#

That works great

#

I’d like commands from IO as ell

#

Well

#

Monitoring is strictly a nice to have

#

IO commands allows Alexa/iftt commands

stray delta Jan 13, 2018, 1:38 AM

#

@ivory wraith I would definitely use the MQTT library instead of the AIO library. That way you have control over the wifi. Here is the WINC1500 example (but looks to be written for the shield...says it works on the feather though)
https://github.com/adafruit/Adafruit_MQTT_Library/tree/master/examples/mqtt_winc1500

ivory wraith Jan 13, 2018, 1:39 AM

Fabulous. Thanks. I’ll check back in with an update

First post: I have a bunch of Raspberry Pis and a Feathe ESP32 using MQTT to send messages to a Mosquitto MQTT broker. The Mosquitto broker is the bridge to Adafruit.io. Works great for data recording and graphs of temperature, etc. I've also implemented a iPhone app using HTTPS and the API to read the data in Adafruit.io and send controls. I have a problem which I've posted. For some reason a switch (ON/OFF) has different information in FEED than in the API data.

Another questions : Is it possible to plug the NEOPIXEL ring 12 led on the 5v Output of the raspberry ( https://www.adafruit.com/product/1643) ? What the maximum mA can you have on the 5v ?

keen dirge Jan 14, 2018, 12:04 PM

#

@cosmic canyon take a look at https://learn.adafruit.com/adafruit-neopixel-uberguide?view=all#driving-5v-neopixels-from-3-dot-3v-microcontrollers. If you power the NeoPixels with 5v then you should also use 5v control signals. For a raspberry pi you should add a “level shifter”. Not a problem, just extra parts. As the guide notes, it may work without it , but it may not. You do not want to allow any device to send 5v signals back to the pi. That could damage it.

@Pankaj#0732 ~~I would ask this question in #help-with-projects. this channel is specific to the AdafruitIO service...~~ n/m..you already did.

//Configure pins for Adafruit ATWINC1500 Feather

stray delta Jan 21, 2018, 5:23 PM

#

@keen shale glad you got it working! sorry I dropped off yesterday...i was out running errands and was waiting on my kid's haircut to finish when I originally answered.

keen shale Jan 22, 2018, 11:21 PM

#

Ok, I'm stuck on something embarrasingly simple... The adafruit IO color picker returns hex values in a "char *" type with a leading "#". In arduino, how do I interpret that as an unsingned long int so I can set my dotstar's colors? The example code uses values that start with "0x"

robust panther Jan 22, 2018, 11:28 PM

#

@keen shale 0x... designates a hexadecimal constant, and so does the # in the color picker, so just substitute one for the other.

#

0xffab12 is the same as #ffab12

keen shale Jan 22, 2018, 11:50 PM

#

But if I cast "0xffab12" and "#ffab12" as uint32_t I get different results. Specifically the ones starting with a "#" are wrong

#

Even more specifically, this is what doesn't work: color = (uint32_t)setcolor.lastread;
strip.setPixelColor(10, color); // 'On' pixel
strip.show();

robust panther Jan 23, 2018, 12:12 AM

#

@keen shale Don't cast the string, cast the value. Could you show your code or point to the example you're using.

keen shale Jan 23, 2018, 12:56 AM

#

In my arduino sketch, if I assign the hex value like this: uint32_t color = 0x001111; and then
Serial.println((uint32_t)color); I get 4369 in the serial console, which is correct. However if I select # 0011111 in the color picker in my AIO dashboard and serial print the resulting feed value like this: Serial.println((uint32_t)setcolor.lastread); I get 536871305 in the serial console, which is very wrong. If I instead do: Serial.println((char *)setcolor.lastread); I get # 001111, which is right. Does that make sense? I want to get the correct integer value from the feed so I can set my dotstar led's color with it.

robust panther Jan 23, 2018, 1:05 AM

#

@keen shale I assume setcolor.lastread is returning a string, not an int. you need to parse it as an int, and just casting won't do that. Could you point to the API definition? I don't have it handy.

keen shale Jan 23, 2018, 1:12 AM

#

https://io.adafruit.com/api/docs ... is this what you mean?

robust panther Jan 23, 2018, 1:18 AM

#

@keen shale sorry, I'm in multiple chats at once. Yes, that's what I mean. So the color is returned as a string "#ff0033" or whatever. Need to convert to an int. Hold on and I will look...

stray delta Jan 23, 2018, 1:22 AM

#

color = setcolor.lastread
int_color = int(color.substring(1))

robust panther Jan 23, 2018, 1:22 AM

#

@keen shale I think @stray delta's version doesn't do hex. This prob will work.

string hexstring = "#FF3Fa0";

// Get rid of '#' and convert it to integer
long number = strtol( &hexstring[1], NULL, 16);

stray delta Jan 23, 2018, 1:24 AM

#

yeah, int would take the long way round...

robust panther Jan 23, 2018, 1:24 AM

#

dont' think int() is a function. It's a reserved word naming a type.

stray delta Jan 23, 2018, 1:24 AM

#

oh yeah...too much python lately. 😄

keen shale Jan 23, 2018, 1:36 AM

np! you understand the [1] starts at the "FF" so it skips the "# and converts the rest of the string to an int base 16

keen shale Jan 23, 2018, 1:42 AM

#

Ah, the # would be [0] then. Makes sense to me... I was just getting fouled up on the data types in C++. This ain't my native language. char, char *, string what the what? Back in my day we had strings and we had numbers, and we were happy with it, dagnabbit

Hey guys I am developing a product that will be powering 4 oled displays. I started with an rpi zero w but moved towards esp8266 and now I am using a esp32. It seems able to handle the task for 1/3 of the RPI price but the question is how to update this device? how to offer updates as easily as possible for the end user? running micropython

stray delta Jan 27, 2018, 3:35 PM

#

@crystal loom you're wanting the OTA feature, but I'm not sure that it has made it into micropython for esp8266/esp32. I'll keep poking at it for a few to see if I can get a diffinitive answer.

stray delta Jan 27, 2018, 3:58 PM

#

there definitely isn't OTA support yet. But, there is an open pull request on GitHub to add it to the ESP32: https://github.com/micropython/micropython/pull/3576

crystal loom Jan 27, 2018, 4:12 PM

#

hm interesting

#

I was actually thinking that otherwise I could pack my own fw with preloaded scripts and provide a easy tool for upgrading the device and backing up the settings

#

but this would be really good if it would work

crystal loom Jan 27, 2018, 4:45 PM

#

but how would this work with settings stored on the device, they would get deleted too. I would need to keep a backup on a server

stray delta Jan 27, 2018, 4:52 PM

#

the Arduino firmware (esp8266 at least) has OTA implemented. I haven't used it, so I can't speak to it much. But, the way I understand it is that OTA only touches the firmware section of the flash; the remaining flash is untouched. so, if you keep static stuff there (like a .ini in windows) it should survive OTA updates. as for the board storing previous WiFi connection information...that I'm not sure of.

#

i would verify all of that though if you go the Arduino route. that is just how i understand it; which could be wrong.

crystal loom Jan 27, 2018, 4:58 PM

#

worst case I could use some kind of hardware id for registration and tie it to an account

#

after fw update the device would just look for the settings on the server and it would only access its own settings

#

for example mac address

stray delta Jan 27, 2018, 5:00 PM

#

well, the esp8266 (not sure on esp32) has a "unique" id. it's not all that unique though. it is the last 24 bits of the MAC address. use import machine and machine.unique_id in mircropython

crystal loom Jan 27, 2018, 5:01 PM

#

that could work. I am not at that stage of the development yet but it seems that I dont need to switch back to the rpi zero w

#

as the problem there was the price, size and the 1 piece / order limit

stray delta Jan 27, 2018, 5:03 PM

#

i love RPi, but for embedded it is usually overkill. I have one project that uses an A+, but the real driver behind that was NTSC video...otherwise I would use something else (and tried on the first couple rounds: arduino and parallax propeller).

crystal loom Jan 27, 2018, 5:08 PM

#

for sure it is a overkill but on the other side there is no fear of running out of memory or processing power. Developing for the esp8266 or esp32 can sometimes mean cutting edges.

#

for example one of these things is using an IMU for determining the orientation for the screens. This is one of the tasks that I MIGHT be skipping because of the 2 core and memory limitations of the esp32 and the fact that getting it to work is really hard.

stray delta Jan 27, 2018, 5:12 PM

#

could you offload the IMU processing with a middle-man? say a trinket (Pro or M0)?

crystal loom Jan 27, 2018, 5:16 PM

#

yes probably but the price is just too high and it needs its own library to function

#

at this point I am considering just adding a button which would enable changing portrait-landscape mode

ivory wraith Jan 30, 2018, 8:07 PM

#

Was there a significant change yesterday on the MQTT lib for Arduino?

#

I need to have it run over an existing WiFi101 connection, and it looks from the GitHub example that it should work...

#

But it's not compiling

#

I see a commit by @vocal berry, but it doesn't look like it's changed since 0.20.1 which is what I have from the library manager

#

UGH! It had cached the library. Saving the sketch with another name forced a rebuild.... Nevermind 😃

stray delta Jan 30, 2018, 8:21 PM

#

Hehe. Was just about to post that the winc1500 references were changed to wifi101. Glad you got working.

Thanks @stray delta I figured it out. And it’s a Bug(!)

stray delta Jan 31, 2018, 12:52 AM

#

looks for bug squashing boots 😄

ivory wraith Jan 31, 2018, 12:52 AM

#

I’m in that you must call subscribe() before you connect().... but a) it should be better documented and b) if you call after connecting you should get an error of some sort!

#

Silently swallowing call and then just not getting requests was painful

#

I’m ok, not in in

#

Stupid autocorrect is killing mr

#

Me

stray delta Jan 31, 2018, 12:53 AM

#

i want to see i've seen that somewhere. may have been with the AIO library...

#

and i am well versed in autocorrect. understood every bit of it.

ivory wraith Jan 31, 2018, 12:54 AM

#

It’s in the .cpp file as a comment

stray delta Jan 31, 2018, 12:54 AM

#

that's probably where i seent it.

Getting Io, local buttons, local http requests and responses to pushing all in the same sketch was a challenge

stray delta Jan 31, 2018, 12:57 AM

#

yeah, that's a lot to squeeze on there. congrats on making it fit.

ivory wraith Jan 31, 2018, 12:57 AM

#

Yeah, once I restructured it to be asynchronous it all worked out

#

I need to pack 😃

stray delta Jan 31, 2018, 12:59 AM

alrighty. have a good trip! keep doing the amazing things you're doing!

@frail citrus you may need to use the standard MQTT library or the adafruit MQTT library separately vs. the adafruit io lib -- depends on how much work you want to put into this

yeah, if you're handling the wifi on your own, then you'll want to go with the MQTT library. the AIO library just wraps the two (wifi, MQTT) together for ease of use.

upper hare Feb 8, 2018, 5:01 AM

#

one more plea for help

#

what is the magic header that the REST API expects?

#

The curl examples I found on the web suggest "X-AIO-KEY", but when I add that, I get a 606 error

#

and nothing in the REST API documentation mentions HOW to send the AIO Key

#

why doesn't the REST API documentation / tester site show the HTTP headers? just knowing the URL and the request body returns errors

#

other than send.json, which apparently only works on "groups" and not feeds

#

(also seemingly undocumented)

stray delta Feb 8, 2018, 5:15 AM

#

@upper hare rando question/shot in the dark: are you using SSL port + http://, or non-SSL port + https://? the 606 error isn't documented anywhere that i could find (API ref or the AIO blog).

upper hare Feb 8, 2018, 5:15 AM

#

@stray delta I've varied the URL with both and enabling/disabling SSL on the SIM808

#

I can POST fine to other services that have custom headers for their id

#

I just can't POST to adafruit.io

#

(and I can't find ANY official documentation that states what the adafruit.io headers are expected to be)

stray delta Feb 8, 2018, 5:17 AM

#

the blog is the only place i've seen "official" header spec.. oh, just remembered. are the messages chunked? i know the arduino http functions ensure that they aren't...

upper hare Feb 8, 2018, 5:18 AM

#

I don't know what that means

stray delta Feb 8, 2018, 5:19 AM

basically, http's version of SPI SCLK.

upper hare Feb 8, 2018, 5:20 AM

#

hell, I have no idea

#

nothing in the SIM808 documentation mentions TE or the word "chunk". If its chunking the encode, there's no way to turn it off

stray delta Feb 8, 2018, 5:24 AM

#

googling is showing 606 is a sim808 SSL error.

#

i can't get the docs. well, i don't feel like another account somewhere. 😄

#

I only saw the one StackOverflow reference which wasn't backed up by any documentation

stray delta Feb 8, 2018, 5:26 AM

is it in the SSL appnotes?

upper hare Feb 8, 2018, 5:27 AM

#

now i'm trying to think if I ever tried without SSL enabled

stray delta Feb 8, 2018, 5:27 AM

#

were you using the SSL fingerprint? found here: https://github.com/adafruit/Adafruit_IO_Arduino/blob/8ccd24687fc1edc0415d26cf05ac0dc930983332/src/AdafruitIO_Definitions.h#L64

upper hare Feb 8, 2018, 5:27 AM

#

i know I had the URL set with and without, but I might have had the SIM808's SSL flag on both times

#

that's interesting, but I have no idea how to use it

#

and that #define statement isn't used anywhere in that code

stray delta Feb 8, 2018, 5:31 AM

#

yeah, i was trying to find it too. been a while since i dug around in AIO/MQTT

upper hare Feb 8, 2018, 5:32 AM

#

MQTT isn't part of the equation

#

I'm trying to use the REST API

#

the goal was to show how to use the Adafruit FONA module, using Adafruit CircuitPython, to connect to Adafruit.io

#

(and, currently, there isn't a MQTT library for circuit python)

#

the rabbit hole I fell into is that the adafruit API isn't actually all that well documented

#

@stray delta thanks for the suggestions. i appreciate you trying

stray delta Feb 8, 2018, 5:43 AM

#

no worries! i'm falling down the rabbit hole with you now...must. find. answers. 😄

stray delta Feb 8, 2018, 6:32 AM

@upper hare verified that 606 is SSL error. From the SSL appnotes: 606 SSL alert message with a level of fatal result in the immediate termination of the connection
Also, looks like you can import a cert, from a file, using AT+SSLSETCERT. Here is the SSL appnotes: http://simcom.ee/documents/SIM800x/SIM800 Series_SSL_Application Note_V1.02.pdf

keen dirge Feb 8, 2018, 2:19 PM

#

@upper hare I don't know if it will help, but I managed to get this to work using the X-AIO-KEY header: payload={'value':'2000'} response=urequests.post("https://io.adafruit.com/api/v2/<yourusername>/feeds/<yourfeed>/data",json=payload,headers={"X-AIO-KEY”:”YOURKEYHERE”})

#

took a lot of trial/error!

#

@upper hare also found this to be a useful way to test my access - using GET : response=urequests.get("https://io.adafruit.com/api/v2/user",headers={"X-AIO-KEY":"YOURKEYHERE"}) print(response.json()) this returns some informaion about you account. see: https://io.adafruit.com/api/docs/#!/v2

upper hare Feb 9, 2018, 4:47 AM

#

@keen dirge well thanks for the help. disabling SSL, I'm able to update. but with SSL, I'm still getting 606

#

I did learn how to install a self-signed client certiifcate to the SIM808, but that doesn't help

#

a workaround i started down the other night is where I'll go next. send the SSL POST request to IFTTT and let it notify AIO

#

or just move on to something else 😉

frail citrus Feb 11, 2018, 12:32 AM

I'm having troubles connecting to Adafruit IO with pubsubclient.

#

I think I am connecting correctly, but nothing ever prints out to the serial monitor like I configured it to when I press the button in the adafruit io dashboard.

#

I'm using wifiManager, I am not sure where it is putting the WiFiClient object. I assumed it just saved it to a variable I already created called espClient, but I am not sure now.

#

I tried changing espClient's name to wifiClient, but it didn't work.

#

Maybe PubSubClient can't access the callback function? The code doesn't compile if I put the PubSubClient mqttclient line before the callback function definition, I thought it should work if the function was later in the code.

frail citrus Feb 11, 2018, 1:10 AM

Now I'm trying adafruit_mqtt library, but I need to subscribe and publish to the same feed, is this possible?

Adafruit's MQTT client is better than PubSub

Quick question - I'm using both a Feather M0 and an Feather ESP32 to log data to IO. When I use the basic "counter" example both boards lock after a certain time. It's definitely repeatable with the M0 board locking after roughly 330 counts. I got around the problem by using watchdog timers, but it bugs me that the boards would just lock up, expecially using and IO demo sketch. Is this typical behavour? Thanks!

hej hej. A short question. I have a website and want to display data from my adafruit.io feeds. Right now I've tried to display the informations via a get function in a setInterval function. But this doesn't seem to be the right way to do this (I'm getting way to many 429 (Too Many Requests) alerts 😉 ) What would be the best way to achieve this?

stray delta Mar 2, 2018, 4:12 PM

#

@dennhaDaReal#3797 if you're only using one feed, that should be within limits. however, if using two feeds, you'll only be able to get a max of four second interval updates. and so on as the feed count grows. I suggest reading the latest throttle update post to get an idea of how you can keep from hitting the 429. https://io.adafruit.com/blog/changelog/2017/12/18/more-throttle-updates/

nocturne coral Mar 2, 2018, 6:42 PM

#

@stray delta thanks for the link. If I send smth from my arduino to the adafruit.io server, will this also count to this?

stray delta Mar 2, 2018, 6:45 PM

#

i believe gets and puts both count. @novel ember, is that accurate?

novel ember Mar 2, 2018, 7:11 PM

#

ehhhhhh, only pushing data counts against the data rate mentioned in that throttling post

#

we have a higher level throttle / denial of service protection on all of IO that cuts off API requests at 60 / min right now

#

could probably bump that up

stray delta Mar 2, 2018, 7:16 PM

#

ok. so pushes = 30/min, and gets = 60/min? just trying to avoid giving inaccurate info out...

novel ember Mar 2, 2018, 7:31 PM

#

data added to a feed or modified counts against the data rate shown on the left hand side of the pages on io.adafruit.com

#

I'm bumping the overall HTTP request rate limit to 120 / min, will take a minute or two to deploy

#

that covers any GET, POST, DELETE, etc.

#

thanks for your help @stray delta!

#

HTTP overall limit has been bumped

#

can't promise we'll keep it at 120 forever, general rule is that if you're getting 429's, you should slow whatever you're doing

#

especially if you have multiple windows open on io.adafruit.com, since they'll all be making multiple API requests

Hey, I was wondering if the 50 data points per min mean that it updates all my feeds 50 times per min?

#

So like if I had 60 feeds, and it updates 60 times per min, does it update one feed every min, or every feed 60 times a min

novel ember Mar 5, 2018, 9:04 PM

#

hey @rapid fox, the data rate is global / across the whole account

#

and the free plan is (eventually going to be) 30 / min

rapid fox Mar 5, 2018, 9:04 PM

#

Still dont know what you mean by that

#

So would all the feeds refresh 60 times a min or each feed once per min (Assuming I have 60 feeds, and a refresh rate of 60 per min)

#

@novel ember

novel ember Mar 5, 2018, 9:06 PM

#

You can push 60 data points to IO per minute

#

1 per second to a single feed,

#

or to 60 feeds all at once, once per minute

rapid fox Mar 5, 2018, 9:07 PM

#

So if I have 60 feeds, they would refresh 60 times per min, or once per min

novel ember Mar 5, 2018, 9:07 PM

#

it depends on how often you push data to them

#

the feeds don't refresh on their own

#

the data rate is only concerned with inbound data,

rapid fox Mar 5, 2018, 9:09 PM

#

Oh, so I could push data only once per min

novel ember Mar 5, 2018, 9:09 PM

#

once per second

rapid fox Mar 5, 2018, 9:09 PM

Or I mean 60 times per min

Hi, I'm try to control a NeoPixel ring with pushbuttons via a Raspberry Pi, where 4 buttons would change part of the rings colors, but not all, could anyone please help me?

clever notch Mar 30, 2018, 10:40 PM

I have two different devices sending feeds to io.adafruit.com. Sometime this afternoon both feeds stopped displaying data and the Adafruit site Monitor is showing these errors for all incoming data: "2018-03-30 15:36:33 error saving data on packetbob/feeds/Freezer_Out, invalid byte sequence in UTF-8" I have reset the devices sending the data (both ESP-8266 based) but still get the error?

fleet geyser Mar 30, 2018, 11:51 PM

#

@crystal topaz , Which part are you having trouble with? (reading pushbuttons, making the pixels change color)
And how "responsive" do you want/expect the button-press detection to be?
I have plenty of neopixel experience on the Arduino side, but haven't done much with RPi devices (tho' I do tinker in Python at work).

graceful sluice Mar 31, 2018, 1:50 AM

#

Hey @clever notch . Still getting those "invalid byte sequence" errors? Have you tried looking at the data you're sending?

clever notch Mar 31, 2018, 2:09 AM

#

Haven't been able to actually look at the data yet as of yet.. Both sending devices are hundreds of miles apart sending the data via different ISPs.. Both have been running fine for about a week.. Data from both failed at the same time.. My thought was that it might be on the Adafruit side... I have reset them and that doesn't make any difference.. Could easily be my code that was cobbled together from the Adafruit examples but I wouldn't have expected it to have run at all then.... I will try deleting the feeds and starting over.... If that doesn't work I will start with a working Adafruit example and then try to see where I went off the rails...

Hi, I have question on adafruit io dashboard. I want to use map block. But is there any format for the feeds can use for map dashboard. Example, if gauge, normal number is enough. Please help.

stray delta Mar 31, 2018, 3:09 PM

#

@molten summit there is no need to spam in multiple channels. things can slow down here on the weekends, so it may take some time to get questions answered.

if i am reading your question correctly, then yes there is a format. each aio feed contains a latitude & longitude field for location data. see this guide for using the map block: https://learn.adafruit.com/geofencing-with-the-fona-808-and-adafruit-io/integration-with-adafruit-io

@stray delta Additional question.. the publish mqtt topic >> “username/feeds/location/csv”?

stray delta Mar 31, 2018, 3:19 PM

#

@molten summit that guide is using the MQTT library. The AIO library extends that library and should handle a large part of the backend stuff. Which board are you [wanting]/using?

molten summit Mar 31, 2018, 3:24 PM

#

@stray delta esp8266 or espressolite

stray delta Mar 31, 2018, 3:27 PM

#

@molten summit the AIO library can be used with the esp8266. espressolite...no guarantees I can make there. the library wraps all of the connection and MQTT stuff into a single library: https://github.com/adafruit/Adafruit_IO_Arduino

Also, if you haven't read through the AIO overview guide, I suggest reading that too: https://learn.adafruit.com/adafruit-io/overview

Hello all, I'm trying to get IFTTT to push a number to my feed in Adafruit IO,. Not sure if it's on IFTTT's end or Adafruit's. My ESP8266's set up and reads AIO fine. The thing is, I want to use Google Assistant -> IFTTT -> AIO -> ESP8266. I've already mailed IFTTT but given that it's Easter and a weekend this might be quicker.

#

I've gone through the overview, API, etc. but can anyone help me figuring out what data I need to send from IFTTT to AIO?

#

Its giving me the option to send the NumberField (the number I require)and a CreatedData to my data. Is there a specific order to those? The CreatedData value (seems?) sends null to AIO whether I choose to send it or not.

#

I have a few pi zeroes and blinkt led strips to go with them. I had been subscribing them adafruit.io to control their state with a bit of node.js. This worked for several months, but it was pretty rough and not ideal. I thought I'd flip to python, just to learn with the kids, which was a breeze! The thing is, the client now disconnects from adafruit.io after a few minutes of inactivity. Which got me thinking maybe this use case is more of a nuisance to the network and I should be polling versus subscribing. The lights get pushed new state updates a few times a day, but can go several hours without an update. What're the thoughts on this? I'm hoping to get some suggestions/thoughts!

shell lantern Apr 13, 2018, 3:32 PM

#

So, I think I need a little help with my IO setup.....

#

What I'm doing is I'm using an esp8266 to listen to a relay on a CNC machine. In the program of the cnc machine I toggle the relay once for each cycle the machine does. But I think I'm getting some interference somewhere or something, and I'm not sure how I should test and adjust to make the setup work....

winged flint Apr 13, 2018, 3:37 PM

#

You might need to debounce the relay

#

ie. wait for 200ms after you first detect it closing, then check if its still closed and then finally do what's supposed to be done when the relay closes

shell lantern Apr 13, 2018, 3:40 PM

#

I think the problem lies in the relay of the machine because I tested it offline with a cheap 5v relay and got accurate results, but now that I'm using the relay on the machine, I get false readings.

#

I haven't had debounce issues, I have the esp dwell for 1s after the sensor reading

#

let me link the data and it'll make more sense

#

📎 unknown.png

#

the actual cycle time is 1:41

#

and some of the data points add up to 1:41....

#

and the actual uninterrupted cycles happen after 10

#

I guess I can link to the actual feed

#

https://io.adafruit.com/kcw8/feeds/lathe6count

Adafruit IO

Adafruit IO is the easiest way to get your projects onto the Internet of Things!

#

I've tried using different relays on the machine (I have 4 different onces to test with), and have had similar results

#

My other thought for a solution, would be to simply have the relay from the machine power on the relay, then in the code for the esp have it send a signal, but I don't know how I would create a counter on the IO side, or how I can store a variable from a previous power cycle of the ESP

winged flint Apr 13, 2018, 4:00 PM

#

so the relay is closing when it shouldn't or the noise is so bad that its able to drive the sense line high for >1 s?

shell lantern Apr 13, 2018, 4:00 PM

#

I think it might be the noise

#

I don't have an oscilloscope to test with.... so....

winged flint Apr 13, 2018, 4:01 PM

#

motors, motordrivers and stuff, its a very noisy environment

shell lantern Apr 13, 2018, 4:01 PM

#

yeah, the motors and drivers are far away (more than 1 ft.)

winged flint Apr 13, 2018, 4:07 PM

#

what value pull-up or pull-down resistor are you using?

shell lantern Apr 13, 2018, 4:07 PM

#

10k

#

pullup

winged flint Apr 13, 2018, 4:08 PM

#

I think that should be fine, a stronger pullup would lessen the effect of noise

shell lantern Apr 13, 2018, 4:09 PM

#

what would you recommend?

winged flint Apr 13, 2018, 4:13 PM

#

I'd go down to 1k or s-t, that's only 3.3mA at 3.3V

shell lantern Apr 13, 2018, 4:32 PM

#

hmmm.... 1k and I'm still getting similar results

#

you think shielded wiring would make a difference?

winged flint Apr 13, 2018, 6:55 PM

#

not sure

#

you can use an arduino as a makeshift oscilloscope

#

while(1) {
Serial.println(analogRead(0));
}

and plot the data it sends back

shell lantern Apr 13, 2018, 7:44 PM

#

I may have to end up doing that

#

I just hooked up another esp8266 to the same circuit, and the weird thing is, it's returning similarly inconsistent data, but totally different data points....

#

¯_(ツ)_/¯

#

This may take more than a quick fix....

winged flint Apr 13, 2018, 7:58 PM

#

hehe, yeah.. maybe shielding is the solution

the most current data point shows a timestamp of the local time.

moving in each direction along the line adds a second or two to the local time

novel ember May 8, 2018, 6:40 PM

Thanks for the heads up @zenith berry! Turns out there was a bug in single-line charts that caused the hover legend text to end up showing the current time rather than the data point time. It wasn't affecting multi-line charts which is probably how it was missed initially.

I've fixed the glitch and updated IO, you should see proper timestamps on all charts now. Feel free to ping me with any bugs or q's in the future if I'm not around.

@raven ore Thanks for the pointer to the elinux.org RPI video config stuff. Unfortunately, when I edited /boot/config.txt, and rebooted with these values: hdmi_group=1 and hdmi_mode=8, the main display (monitor) went black and displayed an error message, and the 2.8" display changed, only slightly. I guess that the doc is just wrong, or the author knows some other magical incantation that I have yet to trip over. OBTW, there is a line near the bottom inserted by NOOBS that set the display to 480x640. Changing that to 240x320 was also for naught. Also, I read somewhere that Linux doesn't really like the small resolutions... if so, than maybe I'll step up to a higher res/larger model monitor for my project.

FOUND THE BUG!

We replaced the backend code that did feed loading and got a big speed boost, especially for folks with more feeds (cut loading time > 50% in most cases) BUUUT the time formatting changed just slightly, but enough that our frontend time rendering library (moment.js) started interpreting the times as local to your browser instead of as UTC, which they actually are.

before: "2018-05-22T12:13:14.123Z"
after (w.bug): "2018-05-22 12:13:14.123"

Now if I can just figure out why I keep getting 400 errors when trying to access webpages from my esp

novel ember Jun 4, 2018, 10:30 PM

#

probably JSON formatting errors,

#

just about the only place we return 400s is when we get bad JSON.

topaz holly Jun 4, 2018, 10:32 PM

#

It's not just from adafruit, I seem to only be able to get 400 or nothing

#

I'm not even using JSON, just manually sending AT commands over serial with the GET/POST and header data

novel ember Jun 4, 2018, 10:33 PM

#

could be similar errors elsewhere, 400 is (supposed to be) a syntax error. Are you using a library to compose HTTP requests?

#

ah

#

yeah, that's pretty low level

topaz holly Jun 4, 2018, 10:34 PM

#

yeah, I've been having a hard time finding examples of doing things at that low of a level

novel ember Jun 4, 2018, 10:35 PM

#

so, not sure if this is you, but I see an error in our error reporting system for a group publish to "smart-wifi"

#

Doesn't sound like mine

novel ember Jun 4, 2018, 10:36 PM

#

cool, cool

#

our server is rejecting it as an "invalid %-encoding"

topaz holly Jun 4, 2018, 10:40 PM

#

Do you know if the "Accept: */*" is required ?

novel ember Jun 4, 2018, 10:40 PM

#

you could always try without

#

most services shouldn't reject a request without it

novel ember Jun 4, 2018, 10:59 PM

#

for example, IO should respond as long as there's a GET line and a Host header. This is the most minimal HTTP request I can get:

#

( printf "GET /api/v2/abachman/public_profile HTTP/1.1\r\nHost: io.adafruit.com\r\n\r\n"; sleep 1 ) | openssl s_client -connect io.adafruit.com:443

#

that's using the openssl command to open a secure connection to IO and then the printf command just spits out those bytes

#

the sleep 1 is in there to make sure the connection stays open long enough for the server to respond

#

that'd be a heck of a way to build an HTTP client, though :P

#

What exactly is adafruit io?

unborn token Jun 6, 2018, 3:46 AM

#

@narrow socket In general, when you make IoT - internet of things devices, you want a central decision maker in the process. So say a bunch of sensors in the field transmit wirelessly back to the central server to datalog all the sensor readings. The data can be stored and analyzed and depending on the readings, maybe issue out a command back to other units to turn the sprinklers on. If this, then that -IFFT. Adafruit has its own IoT server/service which is adafruit.io

narrow socket Jun 6, 2018, 3:47 AM

#

@unborn token thank you for clearing that up

unborn token Jun 6, 2018, 3:49 AM

#

It gets a little more involved than that but the other acronym you will hear is broker services - MQTT - pronounced mosquito - another protocol to add to your vocabulary

#

there's some guides in the Adafruit learn

@gusty lodge you can currently have one feed per map object. You can create multiple maps on a dashboard as a workaround.

Adafruit.io connected project questions. I want to use 2 Huzzah ESP8266 Feathers each with a neopixel ring and an accelerometer attached and connect them through the adafruit.io site. When I shake unit 1, I want the Neopixel ring on unit 2 to light red, and if I shake unit 2, I want the ring on unit 1 to light up green. Two questions, in setting up the Adafruit.io feed, is the accelerometer input considered digital or analog? And, any suggestion which accelerometer board I should use? Any advice is appreciated.

stray delta Jun 13, 2018, 8:26 PM

#

@boreal cargo if you're only reporting shaking or not shaking to adafruitio (AIO), then i would consider that digital ON/OFF. If you'll be using the actual acceleration values as a range, then i guess more "analog".

boreal cargo Jun 13, 2018, 8:30 PM

#

@stray delta - Thank you. Follow-up, could I tell the difference between a left/right vs an up/down movement?

stray delta Jun 13, 2018, 8:38 PM

#

yes. depends on the mounting orientation, but you compare the specific plane's value. assuming "standard" where x = horizontal, y = vertical, and z = roll/pitch: (psuedocode alert; this is generalized Arduino)

int x_last_read;
int x_current_read;
int y_last_read;
int y_current_read;

// |-------- 0 ----------|
//           ^starting point

void determine_direction {
    if (x_last_read < x_current_read) {
        // moving right
    } elif (x_last_read > x_current_read {
        // moving left
    }

    if (y_last_read < y_current_read) {
        // moving up
    } elif (y_last_read > y_current_read) {
        // moving down
    }
}

#

in actual implementation, you might want to buffer the readings a little more than at a depth of one. most accelerometers have pretty fine measurements. think of it as similar to debouncing a button....

boreal cargo Jun 13, 2018, 8:43 PM

#

@stray delta - Got it. Thank you.

worn pawn Jun 14, 2018, 12:16 PM

The LIS3DH modules look very simple, and they're cheaper than most and do some cool stuff like tap detection. If all you really want is shake detection, there's little springy "vibration sensor switches" too, which you could wire straight to a digital input.

I just looked at the client.send() method and it looks like it would only allow a single value to be sent, is that correct? Say I wanted to send Lat, Lon, altitude and feed it to a map on the io dashboard, how would I accomplish that?

@vale dune correct.

What's the best shorthand way to refer to Adafruit IO? AIO? IO? The context is a guide focused on Adafruit IO, so ambiguity around "IO" isn't really an issue.

robust panther Jul 14, 2018, 2:57 PM

@woeful tinsel Brent's brand new guide https://learn.adafruit.com/welcome-to-adafruit-io almost always says "Adafruit IO" and very occasionally just "IO". That just got reviewed, so I guess I'd go with that.

@royal rapids It looks like adafruit-io really does need Python3.6 - posted a few issues with the examples to github -- all resolved when I updated the Raspberry Pi to 3.6.5 -- Mac was already at 3.6.5 and it all works fine there.

@woeful tinsel has the guide been writen or are you just trying to get the code in place so you can reference it?

woeful tinsel Jul 16, 2018, 2:45 PM

#

Guide is in review, references are in place... but nothing to reference yet.

keen dirge Jul 16, 2018, 2:53 PM

I was going to try compiling, but it does not look like the adafruit_crickit library is out yet, Is tat correct?

royal rapids Jul 16, 2018, 2:55 PM

#

@woeful tinsel I'll review as well, @royal rapidsu on git

keen dirge Jul 16, 2018, 2:57 PM

#

compile fails becasue "Adafruit_Crickit.h" does not exist.

woeful tinsel Jul 16, 2018, 3:06 PM

#

You need to install the Adafruit Seesaw lib

#

I need to add notes about the libs to the guide...

#

And also Adafruit IO Arduino

keen dirge Jul 16, 2018, 3:18 PM

#

I did install seesaw, but compile still fails

woeful tinsel Jul 16, 2018, 3:18 PM

hmm

keen dirge Jul 16, 2018, 3:18 PM

ah -- will add IO

woeful tinsel Jul 16, 2018, 3:18 PM

latest with crickit support?

keen dirge Jul 16, 2018, 3:19 PM

just whatever the library mnager gives me

woeful tinsel Jul 16, 2018, 3:19 PM

That should be good.

ah -- crickit stuff is in 1.1.0 --- I have 1.0.1

woeful tinsel Jul 16, 2018, 3:26 PM

You did the thing with config.h?

but I copied config.h to the sketch folder...

woeful tinsel Jul 16, 2018, 3:27 PM

#

config.h at the top level has to have your wifi and io creds added and copied into each project directory

#

well hmm

#

paste your compile trace in as a review comment?

keen dirge Jul 16, 2018, 3:28 PM

#

yup --- but the library manger is only providing 1.0.1 not 1.1.0 -- that is the problem

woeful tinsel Jul 16, 2018, 3:28 PM

ohhh.... that's right

I 'm using the Feather HUZZAH ESP8266

keen dirge Jul 16, 2018, 3:53 PM

actually - I think I'll try it on the M0 WINC

woeful tinsel Jul 16, 2018, 3:55 PM

From what I see it should just work.

keen dirge Jul 16, 2018, 3:58 PM

#

are you sure you want servo_1.attach(CRICKIT_SERVO1, 600, 2400); I had one servo break at those limits

woeful tinsel Jul 16, 2018, 4:00 PM

#

I should add a note about that as well. That was after a series of tweaking the bound to get 180 out of the servo I had.

without it grinding.

keen dirge Jul 16, 2018, 4:00 PM

You can set up a dashboard to inject values to test it without the light sensor. The joy of Adafruit IO (any pup/sub system actually)

you have the feed/group structure/naming right?

#

their external names do

keen dirge Jul 16, 2018, 5:53 PM

ok, ya

keen dirge Jul 16, 2018, 5:57 PM

#

looks like AIO calls it touch-0

royal rapids Jul 16, 2018, 6:01 PM

#

@woeful tinsel you can also change the feed by adding directly to /feed

royal rapids Jul 16, 2018, 7:09 PM

#

@keen dirge ok, it's not what I thought at all. It's due to the feed not having been created on your aio feed list

#

so it tries to send, but nothing is there. I'm going to add feed creation checks to those examples

keen dirge Jul 16, 2018, 7:10 PM

#

@royal rapids I think the location example in api -- did check, but the returned roor message is what failed since it was looking for RequestError and it got TypeError

royal rapids Jul 16, 2018, 7:11 PM

#

I have location working on 3.5.0 without tweaking the script

#

weeeeird

#

like, I have it working with AIO_Python on a RasPi running 2.x, if the feed is created

I thought I had run into that error somwhere else - not just crating a feed. I'll see if I can find it.

royal rapids Jul 16, 2018, 7:34 PM

creating a feed and sending data both invoke _post

_get, _delete, all have the same error handling with the json response which is what you're seeing

#

ok - but it works in 3.6.3

royal rapids Jul 16, 2018, 7:39 PM

So, I'm new to python, new as in I just started today. I have 5 years experience with C though. I'm just trying to get some DHT22 data into Adafruit-IO, with a Raspberry PI. But, the DHT library only works on python 2.7, and the IO library only works on python 3. I have gotten both working separately, but of course merging won't work because of the different python versions

#

So, is there an alternative? I just need to get my DHT22 data into Adafruit IO, but the only internet device I have with GPIO is my Pi3

I do have an ESP8266 running the same thing I'm trying to do, but it's outside

Pardon the stoopid question, I tried researching but am hitting a wall. I've got a solution that uses the ArduinoOTA on my ESP32 platform that I've spent a good amount of time getting to reliably reconnect on WiFi disruptions. As I understand it, the Adafruit IO_WiFi replaces the standard WiFi.h and thus I can't use the OTA components. Can someone just point me in the right direction? I'm happy to research myself with pointers. Thanks!

#

@daring stone You're talking about the input/output pins?

#

This channel is about https://io.adafruit.com, Adafruit's Internet-of-Things platform

tall yew Aug 3, 2018, 2:41 PM

#

I have a project that stores some simple information on Adafruit.io. But I have a problem: when a controller starts up, it wants to get the data that is on the server. But the server doesn't push data back until someone publishes new data, or I manually manipulate my dashboard. I want to query the data, essentially saying, "I just joined this group, please fill me in on the current status". Otherwise, the units don't know the definite state. It is tracking who is in and out, with a wifi box at each of several doors. I'm using the HUZZAH32 processor and the 2.4" TFT screen in each unit I would appreciate if someone who knows how to do this can tell me what methods to use.

#

I am using a group feed, with three feeds, one for each person. The important thing to know at each box who is in and who is out (the last person to leave has to set the alarm). It worked fine in a smaller context where there was only one door, but now there are three. We used to use one simple magnetic board; the person moved a magnet from IN to OUT. So in the event of a power failure or similar interruption, the units need to resynchronize with the master data at adafruit.io.

stray delta Aug 7, 2018, 3:21 AM

#

@tall yew what language/platform are you using (Arduino, CircuitPython, etc)? The only way I've seen to successfully poll for current data is to use the REST API (http calls) and filter out the JSON data for last value. If I could access my desktop, I would put up an Arduino example of what i've used in the past.

#

oh wait...i think i actually have it up on github.

#

@tall yew here is an example (as noted in the file, it was borrowed from an Adafruit forum post): https://github.com/sommersoft/DrumTime/blob/master/RESTfunc.ino

tall yew Aug 7, 2018, 10:33 PM

#

The answer is that I have to use C++, and I'm using it in the context of the Arduino IDE, because CircuitPython has no support for the TFT or touchscreen (I was disappointed because this project was going to be my excuse to learn Python). Thanks for the example, I will try to integrate it into my current code.

keen dirge Aug 8, 2018, 1:05 AM

#

@tall yew there is support for the 2.4 inch TFT in CP. via the RGB display library and the STMPE610 library .

tall yew Aug 8, 2018, 6:42 AM

#

Yes, I know. After I fixed numerous bugs in the Adafruit.io library, I have a working touchscreen interface that directly interfaces to Adafruit.io. As soon as I get another HUZZAH32, I will have a complete working system. Which is why I had to write it in C++. The graphics worked immediately. Took some time to deal with touchscreen, since it has weird behavior.

Hi Adafruit IO Community, We’re excited to tell you about two new blocks we’ve added to Adafruit IO dashboards this week to help you build richer interfaces. Icons and Indicators, two features that…

#

@royal rapids I just saw this... AWESOME!

#

My smarthome system does weather reports on demand (jason data -> text -> speech) and it'd be cool to build a dashboard to visualize it.

#

Now I need a "magic mirror"

#

Hmm.. or just a Pi+displayhat wall mounted by the front door.

royal rapids Sep 4, 2018, 1:36 PM

#

@woeful tinsel sweet! AIO's dashboards are super nice, and the new blocks (like the indicator lights) are configurable.

@keen dirge I'm adding group functionality to AIO Python in a bit

true fossil Sep 15, 2018, 5:44 PM

Hello I am looking for a code example that reliably keeps the connection to adafruit IO open.
I want to send an impulse via IFTTT to an ESP8266 Feather Huzzah with a non-latching relay featherWing.
The Digital Output example code already works great (https://learn.adafruit.com/adafruit-io-basics-digital-output)
But it loses connection after the MQTT times out. I need it to stay alive forever as I want to use it for my garage opener.
I read about the ping() command but need to see a piece of code that works fine in order to understand and implement it into the other bit.
This: does not seem to work anymore?. https://learn.adafruit.com/mqtt-adafruit-io-and-you/intro-to-adafruit-mqtt#pinging-the-server-5-39
Thanks...

MQTT, Adafruit IO & You!

Learn to love the stateful, low-bandwidth pubsub protocol.

true fossil Sep 17, 2018, 7:46 PM

#

@true fossil: If I use the Adafruit sample directly from the Arduino software it works all right.
"io.run()" in the loop function takes care of keeping the connection alive.
Ping is only used with the MQTT library.

royal rapids Sep 17, 2018, 9:07 PM

#

@true fossil We advise using the Adafruit IO Arduino Library, instead of the older Adafruit MQTT library.

#

`io.run() will keep the connection to IO alive. If you want to use the MQTT features (such as pubsub), some examples for that are included in the library. You can mix/match MQTT and the API.

Hey guys, I'm having a small issue which has me a bit confused. I keep getting this error: "...Exceeded the limit of Adafruit IO requests in a short period of time." - How exactly is that calculated (what is considered a short period of time)? I'm also assuming that "aio.receive(my_feed.key)" counts as one request, currently, if I run that at 0.5 seconds, I get this error. Should I adjust my timing?

#

O_O - Even is I send a request once every 5 seconds I get that error...

#

if*

#

Oops... I figured out my problem.

#

I had a continue statement where I shouldn't have; Which was causing a flood in requests, my bad lol

#

I need more coffee, noticed it just reviewing my code over and over and over

royal rapids Sep 18, 2018, 9:25 PM

#

@weak elbow heya!

#

any call to aio.receive counts as a request

#

glad you fixed the issue. if any other problems crop up - just ask away!

weak elbow Sep 18, 2018, 10:02 PM

#

@royal rapids heya! Thank you very much, I appreciated that. This community is awesome.

Is there a way to alert when a device stops transmitting to IO?

#

It normally uploads every minute

royal rapids Sep 23, 2018, 8:03 PM

#

@gusty lodge If it's a changing value, you can check against the feed's last value

gusty lodge Sep 23, 2018, 8:10 PM

#

I made a power outage monitor to go with my freezer alarms, it will ping a separate pi at food pantry, alert me if it's down for 5 min, then tally up the downtime and send total when it's back online. I want to confirm it's an real outage by making sure the freezer alarms aren't still transmitting. Maybe I can access the feeds with the outage monitor to confirm based on last timestamp?

@gusty lodge Just some interesting stuff I ran across on temp probes related to what you are doing. http://www.accucold.com/glycolbasedprobes

Why do the CDC and other medical refrigeration experts recommend using glycol-encased temperature probes when monitoring the temperature of a refrigerator? An experiment was conducted in Accucold's laboratory facility to find out the answer.

gusty lodge Sep 23, 2018, 8:25 PM

i could definitely try that @unborn token

#

these values seem to be 10min off. Data(created_epoch=1537676464, created_at='2018-09-23T04:21:04Z'

It seems like I can only access data 10min or older

royal rapids Sep 23, 2018, 8:41 PM

@gusty lodge are you using the get() function added to adafruit io recently?

no

    for d in data:

@royal rapids you want me to close the issue?

you nailed it

*comment and I'll close it out

#

glad that's what the issue was, the data object has a lot of good stuff in it

gusty lodge Sep 25, 2018, 5:55 PM

#

that was what i need to be able to do so i can double check my power outage monitor

#

so now if someone unplugs the machine im pinging there wont be an outage alert sent, unless all 6 freezers stop uploading to IO as well

gusty lodge Sep 25, 2018, 7:57 PM

#

i added the new feature to my outageReport program.

I'm working on a guide for the freezer project, I just need to get some more pictures of it installed next time I'm there. I'm gonna make a 2nd power outage program that just uses IO instead of pinging a separate device first to include in the guide

The io program will only alert when all feeds are down, then after the all down alert another alert will happen when they are all back up.

Quick question: Is it possible to have a line graph of binary values that doesn't average them out?

#

I have a motion sensor feed, and I wanted a graph where I can see when there were motion "events", but the line graph seems to be averaging all the 1's and zeros to various fractions...

Hello, I'm fairly new to adafruit and have been trying to code my own app to connect over bluetooth and send UART to Serial messages that can turn on and off the LED on the BluefruitLE 32u4. I've been successful with the adafruit app, but while making my own, I discovered I've been creating the socket incorrectly.

#

I'm digging into the code for the adafruit app, and I'm trying to find exactly where the "socket" is created. In my app, I use <code> (BluetoothSocket) btsocket = (BluetoothDevice) btdevice.createRfcommSocketToServiceRecord((UUID) uuid) <code/> but in the adafruit app, theres a bunch of internal methods that get called

Anyone have any recos for something that works similar to these? https://www.adafruit.com/product/1558

Breadboard-friendly RGB Smart NeoPixel - Sheet of 25

So, you want lots and lots of NeoPixels? And you want them for less? Not a problem! Here's a sheet of Breadboard-Friendly NeoPixel breakouts fresh from the (reflow) oven. Snap them off ...

#

I would prefer something with 0.1 rows of three on each side like this rather than the Flora single Neopixels, as I need to daisy chain single Neopixels every 15" or so in an enclosure, but it doesn't look like these are being sold any longer

#

Otherwise, considering making my own little breakout boards that work with the through-hole Neopixels

yeah, those are the through-holes I was mentioning. Looks like its probably the easiest option, but I'll have to fab some boards myself. Thanks

flint violet Oct 18, 2018, 10:36 PM

#

Just going to throw this out there and see if anyone has any thoughts. I have a feather huzzah ESP8266 and I wanted to hook it up to a few meters of LED strips (either Neopixel or Dotstar) so that I could connect to my phone and change the colors and brightness through the color picker. Can I not do this because of power restrictions or for some other reason? Any thoughts would be helpful. Thanks!

unborn token Oct 18, 2018, 11:05 PM

#

@flint violet I'm just gonna ramble on some things since I have not worked with ESP stuff - The color picker is a bluetooth app, other projects I've seen go the IoT wifi route to get the commands to the board. If you are talking long strands of neopixels/dotstars, external power requirements are a concern, and then you probably want to level-shift the 3.3v board logic to 5v for the neopixels. Also, depending on what coding you are doing, neopixels take up a lot of memory for basic data (RGB values, etc) and then if the processor can handle manipulating it if you have fancy animations. Others will pipe in for advice. Good luck.

flint violet Oct 19, 2018, 1:15 AM

#

thank you so much @unborn token

unborn token Oct 19, 2018, 1:59 AM

#

@flint violet Not really sure what you had in mind "a few meters" of neopixels but say max 200 neopixels to use would be a good working estimate and meters of neopixels come in 30/60/144 neopixels per meter strips. Start out small and see what you would really need. Neopixels are really bright. Dense matrixes are difficult to do without additional hardware and more advanced programming. Look up the FastLED google+ discussion group where they show off the more "art installation" or more complex displays and you might find they have done what you were planning to do or get an idea from their projects.

scarlet pendant Oct 19, 2018, 4:22 PM

On the Feather nRF52 I have about 30 Neopixels connected and I had it working with the Neopixels powered by the BATT pin. I am using a 2500mAh Lipo, plugged into the onboard JST. I ran the battery dead overnight too see how long it would last. After having it powered via USB for over an hour, when I pulled the USB cable, the whole thing went dead, the initial script is no LEDs on, so It's not a power drain, its like the feather isnt charging the battery. Am I missing something simple?

sacred depot Oct 20, 2018, 5:32 PM

#

That charges at 100 mA which takes a long (long!) time to charge (it's inappropriately small).

#

It is possible to change out the resistor to alter the charge rate (this information is in the product schematic)

My problem is every time I turn off or dissconect a strip and board from power, I need to upload my .ino program onto the board all over again in order for them to work. How can I fix that? I am using the artnetwifi example in the artnetwifi library by rstephan. Should I post my code here?

Oh :o

sacred depot Oct 21, 2018, 1:29 PM

it doesn't do anything at all. After I disconnect power, I have to start over again and reload the board and then everything works fine. Why is that?

ember fox Oct 21, 2018, 2:30 PM

#

I do suppose that when the program downloads to the ESP8266 flash you get a OK message to say all went well. If that happens and yet the program does not stay when you power down ... well it can only mean one thing : The flash on the ESP is behaving like a RAM. One more Feather to check ??
