#

@sacred depot I'd love to help but I don't have either of those pieces of hardware

sacred depot Oct 11, 2019, 10:26 AM

#

@sacred depot would you tell me is it a arduino program problem

south gust Oct 11, 2019, 10:53 AM

#

@royal rapids You have any thoughts on that IO Map block question or is it not doable? That's fine too.

sacred depot Oct 11, 2019, 2:48 PM

#

@sacred depot I would suggest you break it down into chunks. Try sending test values to Adafruit IO and see if those come up, then try a test sketch to make sure you are reading local sensors ok, then third combine the first two

#

@sacred depot it just all the sensor data trapped in the uno side, none of them are transmit to esp8266. beside, the mqtt connection between io and esp8266 are ok now.

eternal cliff Oct 11, 2019, 3:21 PM

#

This is an asychronous serial link from the Uno to the ESP8266?

sacred depot Oct 11, 2019, 3:31 PM

#

both set up are 115200

eternal cliff Oct 11, 2019, 6:02 PM

#

I'll take that as yes. What I'd do next is verify the Uno is sending (a simple LED with a current limiting resistor should show traffic by flickering). If it's sending, then I'd see if the ESP8266 is receiving.

Hello, I am curious if there's a way to remove the feeds data (let's say 300 data) without deleting the whole feed?

royal rapids Oct 16, 2019, 6:41 PM

#

hi @uncut imp , in short - yes! you can remove the data points.

#

However, removing a data point is considered an API action and subject to the data limits of your Adafruit IO plan. You may hit an error when attempting to automate/remove a large amount of data points at once.

uncut imp Oct 16, 2019, 6:48 PM

#

@royal rapids I see. I'm trying to do data collection in different periods of time with using the same feed, and save the data (in certain period) in .csv files separately. My alternate solution is to delete and set up the same feed again every time I run the data. My goal is to not have accumulative data in my .csv file each time I save it.

royal rapids Oct 16, 2019, 7:51 PM

#

@uncut imp Could you filter by data/dates in the CSV file? or use separate feeds for separate periods (feed_per1, feed_per2...)

uncut imp Oct 16, 2019, 8:06 PM

#

@royal rapids I'll try it, thank you!

royal rapids Oct 16, 2019, 8:07 PM

#

@uncut imp no problem, let me know if that works (or doesnt..) and I'll figure out some other options w/you

#

Is there a way to condense multiple aio.send_data operations into a single push? I'm trying to minimize the number of uploads/updates my script makes. My script minus the imports and AIO keys looks like this: aio.send_data(enclosurehumiditygrey.key, ehgrey) aio.send_data(enclosuretemperaturegrey.key, etgrey) aio.send_data(ambienthumiditygrey.key, ahgrey) aio.send_data(ambienttemperaturegrey.key, atgrey) aio.send_data(cputemperaturegrey.key, cputempgrey) time.sleep(30)

abstract mica Oct 17, 2019, 3:33 AM

#

it doesn't look like there is an API endpoint for submitting data to multiple feeds at the same time. You could upload multiple records to a single feed but that isn't what you want.

sacred depot Oct 17, 2019, 5:43 AM

#

Thank you. I had looked over the example and didn’t see the option, I was hoping I had just missed it. I’ll probably go tweak my timings to save on data points.

royal rapids Oct 17, 2019, 1:07 PM

#

@sacred depot There is an endpoint for sending multiple data points to one feed, you could also condense the data into metadata for that data point.

#

i.e: provide IO with a json-formatted data payload containing information about multiple sensors, in one io.send_data

#

then parse it (unless you want it on a dash.)

royal rapids Oct 17, 2019, 7:39 PM

#

@sacred depot Also - thanks for creating a HUGE dashboard, I've been looking at it for inspiration for a few things. It's also a good example.

sacred depot Oct 17, 2019, 7:41 PM

#

Thanks! Two questions- is there a way to submit multiple feeds at the same time, like ehgrey, etgrey? If I do, does that count as one upload or two on my IO+ cap?

#

One wishlist item is a radial/gauge that has two rings/values. All I really want is to compare ambient and enclosure temps

#

I couldn't get it working on CP the way I wanted, or else this would be a great Adafruit IO Thermostat 🙂

#

Let me know what you think @royal rapids

royal rapids Oct 17, 2019, 7:50 PM

#

@sacred depot 1) is there a way to submit multiple feeds at the same time, like ehgrey, etgrey

#

That counts as two uploads, it creates two data points and performs two API actions.

#

An interesting way to think about IO is as a _ great_ API with a really nice web interface. For example, IO Web (like clicking around, etc) actually uses the MQTT API and creating feeds from there shows up like any client would.

#

The radial gauge is interesting, do you have any examples of this in other services/web designs/product designs? Adding new blocks is something I can request from the IO Web development team.

sacred depot Oct 17, 2019, 8:24 PM

#

@royal rapids let me mock something up, but the wishlist item would be very compact, one radius gauge just like now, a smaller radius inside it, and a third value in the "value" field in the middle. My use case is to show two temps on the radial gauge, then the delta in the middle.

#

📎 img8982412967092917994.png

#

by the way @royal rapids you can see how some data sources are very unreliable, like the REST data from Octoprint. I know it's only one developer, but the value for print ETA is going to teach me better error handling 🙂

royal rapids Oct 17, 2019, 8:27 PM

#

I did a multi-printer octoprint hub a while ago, it was unreliable but worked OK.

#

@sacred depot Ok, I like the dual-feed gauge idea. I filed a feature request for the IO team. These feature requests arent urgent and sometimes get added, sometimes dont. I can't guarantee its implementation

sacred depot Oct 17, 2019, 8:31 PM

#

Thank you- that's cool either way... I would love to see it implemented. I'm almost done with this one and will probably make an ultra compact mobile-friendly view. What would be really awesome is the ability to embed a gauge into a different webpage. Imagine being able to share a single gauge via thumbnail on Twitter, etc. or just on a blog.

#

I'll end up cleaning up my scripts and writing a Learn article on this too- but I need to clean up my sloppy time.sleep statements so people don't blow through their update caps. Debug was 1s delay for the first pass, and

#

I changed that quickly

royal rapids Oct 17, 2019, 8:51 PM

#

Yep, we've internally discussed doing embeds but only for blocks

#

If you want to write a learning guide about this project and aren't set up - feel free to email me (brent at adafruit dot com) and I'll point you in the right direction.

sacred depot Oct 17, 2019, 10:05 PM

@royal rapidsu I am already set up- thank you. btw, there's an active print going on for the next ~5hrs so you can see the "black printer" doing a job. The grey printer is in a pile 🙂 https://io.adafruit.com/jdoscher/dashboards/back7-factory

Can I use the momentary or toggle blocks to launch an external web page in its own browser window or tab? In my instance I want to launch a specific NOAA tide station that is in proximity to where my weather station would be located. NOAA has a section called CO-OPS where all that type of stuff resides and I'd like to find a way to integrate that in to the weather station IO Plus setup.

It has several formats such as json, csv but can I pull the data in to a line graph as another option

south gust Oct 19, 2019, 11:32 AM

#

@royal rapids Are there any tutorials / examples of webhooks in IO that are real world rather than the API documentation to see if that can be applied to fetching data from NOAA and plotting it in line graph. Documentation implies it is possible.

Hello and HELP:

I connected Gemma v2 with a USB2 cable, but I can't see an icon on my laptop (macOS High Sierra, 10.13.6) - it is not recognized!!!

For a workshop with kids I wanted to use Gemma aswell with Windows 7 / 10 - I have installed the driver but I and can't see the Gemma either... there is a sound when I plug in but I cannot see the Gemma in my devices,,,

What can I do??? Please HELP!!

Kind regards, Panzi

eternal cliff Oct 22, 2019, 2:34 PM

#

The Gemma v2 is an older design which attempts to emulate USB in software, and the emulation is necessarily imperfect. More modern systems are likely to have issues with it.

#

As the product page https://www.adafruit.com/product/1222 states up top, in bold print: "Deprecation Warning: The Gemma bit-bang USB technique it uses doesn't work as well as it did in 2014, many modern computers won't work well. So while we still carry the Gemma so that people can maintain some older projects, we no longer recommend it."

#

Did you start the bootloader properly? It doesn't enumerate as a storage device like newer boards, it only shows up as a limited serial device when it is in bootloader mode.

sacred depot Oct 22, 2019, 2:51 PM

#

Hello Madbodger, thanks for this info: I was buying the Gemma just last week and thought it is a new model - there are just v2 to buy here (I am living in Germany). Because I am quite new into adafruit: What exactly do you mean when you write if I started the bootloader correctly?

I wanted to program this with make code - https://learn.adafruit.com/neopixel-spats/code-with-makecode - but I do not understand how to download it to the Gemma V2 because it is not shown when I push the green button "klicken/click"... and in general: do you think this make code will only work with the Gemma M0?! 😦 I am a bit upset now...

hi, i have a general question about adafruit.io. I would like to get 5 things on my adafruit.io dashboard (live instagram/twitter count, gps-data (daily distance, distance from location) and possibly weather data. My idea is to utilise a Adafruit Flora + Bluefruit LE (Module & App). Thus, I will be using adafruit.io, with all these data on the dashboard.

#

I have found an example for youtube-subscriber counters (coded directly in Arduino, using wi-fi). However, I need to get all these social-counters + gps + weather on adafruit.io dashboard. I have followed the example of github webhooks & reviewed ifttt applets. What would you recommend on pushing GPS-data + socialmedia-counters?

pastel citrus Oct 24, 2019, 11:29 PM

#

to be more specific, i need help with 'adafruit.io receiving external JSON' and pushing it on a dashboard

pastel citrus Oct 25, 2019, 7:38 AM

#

I have tried Zapier integration, but for some reason I cannot work it out, even though I got the status to '200' on it, instead of IFTTT (which seems to have outdated tutorials, since I could not adjust much on webhooks anymore)

pastel citrus Oct 25, 2019, 2:13 PM

#

I have decided to carry on, hoping somebody notices. I've managed to connect InstaJSON -> Google Sheets -> IFTTT -> Adafruit.io

#

No update though

#

Google sheet needs to be updated automatically, which is another challenge.

Hmmm, trying to send a URL through the IO image formatter, and all I'm getting back is a JSON error, error: request failed - failed to load and process image

#

Other plain http and https URLs appear to work, but this one I need to use is generated, and the URL has parameters

#

I suspect it's the ? and & parameters tripping the IO service up but I'd appreciate clarification!

languid frigate Oct 27, 2019, 3:44 PM

#

hmm, appending parameters to a known good URL still works. maybe the service is blocking IO?

@royal rapids Thank you very much for your kind answer. So far, I have progressed enough to 'post' a follower count to my Adafruit webhook, using Zapier's service. However, Zapier's webhook integration do not get updated every single time as you mentioned, requiring me to set it up for a time-span (hourly/daily). I would possibly set it up directly from Instagram and other services as you mentioned. I think this part of problem is solved. However, I'd have to say that I would be much more willing to pay for adafruit.io for recurring (or triggered) requests than other services. Do you have any recommendations/alternate methods to post data manually to adafruit.io? What would be your recommendation for getting the GPS data over Bluetooth App and to MQTT? Thanks a lot again for your time and informative answer.

royal rapids Oct 29, 2019, 2:57 PM

#

@pastel citrus Right, Zapier takes a while to perform actions (anywhere from 15min to 1hr). You can use Adafruit IO's webhook capability directly and bypass Zapier.

#

What do you mean by "recommendations/alternate methods to post data manually to adafruit.io"?

#

We have two public APIs, the HTTP API and the MQTT API. I suggest using the HTTP API (https://io.adafruit.com/api/docs/#adafruit-io-http-api) for ease-of-use and creating new data using the endpoint (https://io.adafruit.com/api/docs/#create-data). We have samples on that page for using the API with cURL, Python, Arduino, or Ruby. Use whatever you're most comfortable with

#

What would be your recommendation for getting the GPS data over Bluetooth App and to MQTT?

#

Admittedly - I don't do a lot of bluetooth work with Adafruit IO. The supported method is connecting your BLE module to Bluetooth LE Connect and bridge it to Adafruit IO with your Phone (https://learn.adafruit.com/datalogging-hat-with-flora-ble/bluefruit-le-connect-settings). Your other option would be to use a WiFi-enabled board or breakout (do not need to rely on your Phone as a bridge between BLE and WiFi).

pastel citrus Oct 29, 2019, 3:11 PM

#

I have already received (just today) my Circuit playground and Flora packages. The reason I went for non Wi-Fi alternates was being easy to sew. Huzzah seemed harder for that purpose. But, I might get that as well, if necessary. I'll try my best to get live GPS-data from iPhone (similar to GPS-distance showing Jacket example) to MQTT, which will be probably quite a challenge to find. I will probably get help from a back-end developer to set up a cloud service that posts my GPS-data as well as stats counters.

#

Thank you very much for your help.

royal rapids Oct 29, 2019, 8:33 PM

#

@pastel citrus Are you able to post to Adafruit IO from your Flora and the BLE Connect app?

pastel citrus Oct 30, 2019, 1:34 PM

#

@royal rapids I have connected my Flora & Bluefruit, I had the chance to update through the App. I only got stuck at the 'atcommand' sketch. As I cannot factory reset. as soon as I figure this out, I think I will be very close to say 'yes' to your question.

pastel citrus Oct 30, 2019, 2:07 PM

#

@royal rapids I have managed to get to UART mode running (big leap so far)

pastel citrus Oct 30, 2019, 2:33 PM

#

@royal rapids Yes, I did. I have an Insta-Follower slider which does not get updated continuously. Now, it is possible to see the numbers and control the sliders.

#

@royal rapids I need to be able to 'get' Instagram and Twitter follower-counts repetitively at the same time (to change colours of different neopixels) + one gps neopixel that receives lat-long from iPhone. Let's say I use Zapier for that. But, with the App I can only connect to a single feed. Is it possible to connect to multiple feeds?

#

Final Q: I can send my GPS-data in 'Controller' mode of the App. However, whenever I switch screens, the feed is killed. Is there a way to 'get' multiple feeds from adafruit.io using UART mode, and send GPS (lat-long, elevation) simultaneously?

pastel citrus Oct 30, 2019, 3:04 PM

#

Current Status: I followed the tutorial here: https://learn.adafruit.com/bluefruit-le-connect/mqtt and i can in between iPhone & arduino, iphone & adafruit.io, but not "adafruit.io & arduino" (feed on macbook only receives from iPhone). the 'output' feed does not seem to work. This is an additional issue, next to my multiple-feed problems.

In IO+ can you put an upper & lower limit on a line chart? Having a static feed to create a high and low doesn't seem like the most viable way to do that.

hushed sigil Nov 8, 2019, 4:18 PM

#

@ornate kettle I see two IPs when I "dig io.adafruit.com"
io.adafruit.com. 240 IN A 52.7.124.212
io.adafruit.com. 240 IN A 52.72.201.158

I would whitelist those.
Those IPs are part of Amazon's AWS cloud. So the IPs might change if they do some backend maintenance with their virtual machines, and you'll be stuck with old IPs in your white list. Can you white list the domain name?

ornate kettle Nov 8, 2019, 4:33 PM

#

@hushed sigil I tried whitelisting the domain name, and it only whitelisted the ports 80 and 443. Which led to partial loading of the main page. Now, when I asked them to whitelist the mqtt non secure port(1883) on the domain name, esp32 couldn't connect. The esp couldn't connect on the normal ports of 80 and 443 too for mqtt(this is what I tried first.)
P.S the esp32 can connect normally. The problem arises when people try to blacklist everything, and then try to whitelist one by one.

@ornate kettle When you say "they" is this your work or university's IT department?

ornate kettle Nov 8, 2019, 5:20 PM

@hushed sigil sorry I meant the SIM card providers. They have specific sims for IOT. For security reasons, they recommend blocking everything except the ones that are required. Actually not recommend, but forcefully do so. 😅

I just did a netstat on my computer and I see a connection to ec2-52-7-124-212:8883 when I connect my python script to adafruit io. Maybe you just need port 8883 open for 52.7.124.212?

non-secure would be port 1883, but you should use the secure if your board is capable of it

@south gust Were you trying from the library or the web client? Both?

south gust Nov 11, 2019, 4:28 PM

#

I guess it would have been from the web client

royal rapids Nov 11, 2019, 4:28 PM

#

IO Web has a small "add to groups" box for when you're creating a new feed. Seems to work.

📎 unknown.png

#

@south gust hrmm, where did you find the "feature on the IO+ site that you can select a feed and move it to another group"

south gust Nov 11, 2019, 4:32 PM

#

@royal rapids It's under the groups option. For me, I have a group titled WEATHER. If I select that group, then in the ACTIONS drop-down there is a selection to move a feed and all the feeds I've created are listed but if one is selected, ultimately nothing happens

royal rapids Nov 11, 2019, 4:34 PM

#

@south gust here?

south gust Nov 11, 2019, 4:34 PM

No, let me grab a couple of images

royal rapids Nov 11, 2019, 4:34 PM

#

Thanks! As much data as possible is helpful for filing issues.

south gust Nov 11, 2019, 4:36 PM

@royal rapids

📎 unknown.png

#

I can't recreate it completely now which may because I have the system shutdown. What I could do was to select WEATHER and it would come up with not the page I built but a very similar page as this but in the actions drop down there was an option to add a feed to the group.

#

@royal rapids I figured it out. Give me just a moment to grab those images

#

📎 unknown.png

#

In Feeds, View All, then select the Group at bottom weather.

Oh, odd, I see it.

That's a bug 🐛

It's a well built bug. It would be nice if it worked but what little I've read and understood about feed keys it might be problematic

royal rapids Nov 11, 2019, 4:54 PM

Submitting an internal bug report.

#

@south gust I'm going to document and submit it. I'll ping you when it's been resolved.

Okay. Thanks

#

@pastel citrus hi - I'm back. I posted up on the forum topic about the issue you're having along with a potential fix. I think the data length is the issue.

#

You may be able to resolve it without changing library code. If you run into a limit (this one is likely physical, because of the transport you're using) with sending large chunks of data to Adafruit IO - you could split the data up into chunks of data.

#

For example - instead of sending lots of data to a single feed - try performing multiple sends of <90chars to multiple Adafruit IO Feeds.

#

@ornate kettle Were you able to unblock the IPs related to Adafruit IO?

south gust Nov 11, 2019, 9:05 PM

#

@royal rapids I'll do that. Seems like it would be similar to the high and low alerts you can set in the gauge block would be optimal. Setting a static number as a data point just another data point to upload.

royal rapids Nov 11, 2019, 9:05 PM

#

Right, we could absolutely add it. Block features are some of the best suggestions to make for the service since they're easy-ish to implement 🙂

#

(I like the idea, at least 🙂 )

pastel citrus Nov 12, 2019, 11:54 AM

#

@royal rapids I am really short on time, I hope to be able to find a solution with a workaround. The fix on the forum unfortunately does not work, and it was something I have tried before. I have also found a git issue that was not implemented on the MQTT library, and I could not figure out where the fix should be applied to. The link is: https://github.com/adafruit/Adafruit_MQTT_Library/issues/17

GitHub

Packet Length Issues · Issue #17 · adafruit/Adafruit_MQTT_Library

there seem to be a couple issues with the publish packet length. currently the payload seems to be limited to 128 chars. i think the problem is related to length being stored as uint16_t, and sent ...

pastel citrus Nov 12, 2019, 2:14 PM

#

Zapier is very frustrating with its limitations when trying send 2 values in an object or array. I am shocked by how much I struggled with sending 500 bytes of data, or filtering it to BLE device.

Hi

pastel citrus Nov 12, 2019, 2:34 PM

#

Hi

royal rapids Nov 12, 2019, 2:34 PM

#

Just got into the office

#

So it's possibly a few things, IoT projects are very hard to diagnose

pastel citrus Nov 12, 2019, 2:34 PM

#

No worries, it's late night here down under. Tomorrow is the final demo day for my project.

royal rapids Nov 12, 2019, 2:35 PM

#

Ok, so, what specifically, is not working at this point

pastel citrus Nov 12, 2019, 2:37 PM

#

I cannot send anything other than 100~ characters from Bluefruit LE App to BLE

royal rapids Nov 12, 2019, 2:37 PM

#

What OS are you on

#

on your phone, android/iOS?

pastel citrus Nov 12, 2019, 2:37 PM

#

iOS

royal rapids Nov 12, 2019, 2:38 PM

#

Ok, I'm going to file an issue with the developer for the BLE App. It may be an app issue.

#

Unfortunately, that means this issue will need to be looked into by a developer and will take time (I dont work on Adafruit's iOS apps)

pastel citrus Nov 12, 2019, 2:39 PM

#

I see it in the feed completely adafruit.io -> Bluefruit LE

#

OK, I see. But I think this sounds more like a MQTT problem (looking at the latest link I sent).

royal rapids Nov 12, 2019, 2:43 PM

#

It looks like ladyada impl'd the fix and tested it?

#

I'm not sure exactly where the issue in the library is..

pastel citrus Nov 12, 2019, 2:44 PM

#

I downloaded the MQTT lib from github. Maybe I am copying it at the wrong place

#

since it's been so long, i think arduino libraries must have been updated too

royal rapids Nov 12, 2019, 2:45 PM

Oh, hmm I have an idea

@pastel citrus have you tried increasing this?

pastel citrus Nov 12, 2019, 2:47 PM

#

I'm testing it now.

royal rapids Nov 12, 2019, 2:48 PM

#

worth a shot, it's the most relevant #define for what you're looking for (imo)

pastel citrus Nov 12, 2019, 2:49 PM

#

didn't help.

royal rapids Nov 12, 2019, 2:50 PM

#

Did you make the change while Arduino was closed, and open arduino ide after you made the change?

pastel citrus Nov 12, 2019, 2:50 PM

#

No I didn't, Let's restart it.

#

nope, it didn't help.

royal rapids Nov 12, 2019, 2:53 PM

#

What did you increase the buffer size to?

pastel citrus Nov 12, 2019, 2:54 PM

#

600

#

my test data was around 432

royal rapids Nov 12, 2019, 2:54 PM

#

432 bytes?

#

and only ~100 characters are being sent, right?

pastel citrus Nov 12, 2019, 2:54 PM

#

yes

royal rapids Nov 12, 2019, 2:55 PM

#

Is there a way you could send less data, or is the GPS data very large?

pastel citrus Nov 12, 2019, 2:56 PM

#

Yes, Zapier has a function to Catch webhook, and then it forwards a specific value, however I need to send 2 values at the same time. lat & long (at least 2).

#

Zapier does not support 2 values in one post (possibly to avoid multiple automations at once)

royal rapids Nov 12, 2019, 2:57 PM

#

Dang, the buffer size is the main thing from the hardware side. I wonder if it's the packet is truncated by the MQTT client from the iOS app...

pastel citrus Nov 12, 2019, 2:59 PM

#

I can test the ios app with MQTT.fx maybe?

royal rapids Nov 12, 2019, 3:00 PM

#

not sure, I haven't used the iOS app before. dont have much experience with it.

pastel citrus Nov 12, 2019, 3:01 PM

#

This is actually not testing it, but it might help me modify my feed

#

I think I made Zapier send me two values send two numbers with a comma separated value

#

Do you think it is possible to assign them to variables in Arduino?

#

(I am a newbie in coding)

#

This might be the workaround. I use "name/g/groupname/json" as subscription

royal rapids Nov 12, 2019, 3:21 PM

#

What does the subscription look like?

pastel citrus Nov 12, 2019, 3:29 PM

#

-12.1234567890,123.4567890

#

and the feed is: [Recv] {"feeds":{"latlong":"-12.1234567890,123.4567890"}}

#

I changed the numbers, but the format looks like this

#

I can't really get an array

#

the value zapier shows is this -12.1234567890,123.4567890

#

@royal rapids apparently the digit number is the same

#

this might solve it for me probably

royal rapids Nov 12, 2019, 3:46 PM

#

Digit number? Do you mean the value?

pastel citrus Nov 12, 2019, 3:47 PM

#

no, number of characters

#

it goes like this

#

12.345 , 123.45

#

so if i can divide the string into 2 strings, and then (maybe with string token or smth like that) i can float those 2 newly generated strings

#

and then assign vars and do the calc

#

i can't generate 2 separate strings from one

eternal cliff Nov 12, 2019, 3:57 PM

#

What language? It's fairly easy to break up strings in C, Python, etc.

pastel citrus Nov 12, 2019, 4:03 PM

#

Arduino

#

I have a string looking exactly like this

#

-12.1234567890,123.123456789

#

so I need to extract -12.1234567890 as var1 and 123.123456789 as var2

#

@eternal cliff minus sign makes things more complex though.

#

alternatively: I need smth that will take the characters as a float (or short) until the comma arrives, and the second number is as var2

eternal cliff Nov 12, 2019, 4:16 PM

#

char * dp = strchr(data, ','); // find comma

*dp++ = '\0'; // terminate first string, move to second string

float num1 = atof(data);    // convert first number to float
float num2 = atof(dp);     // convert second number to float

#

That's assuming your string is a C style string, an array of characters. If it's a C++ style String object, it's slightly different

pastel citrus Nov 12, 2019, 4:25 PM

#

Arduino got stuck at uploading stage

#

strangely

#

It works, but with a trick.

#

I an only get 6 digits, if i make it short, it would probably be solved, right?

eternal cliff Nov 12, 2019, 4:30 PM

#

That's about as many digits as fit in a float. A short is an integer quantity, which is probably not what you want.

pastel citrus Nov 12, 2019, 4:30 PM

#

then i'll want long

eternal cliff Nov 12, 2019, 4:30 PM

#

On some CPUs, a double will have more digits, but many of these small ones, it's the same as float.

pastel citrus Nov 12, 2019, 4:31 PM

#

i was thinking about single, i'm terrible : )

eternal cliff Nov 12, 2019, 4:32 PM

#

long is also an integer. I suspect that double is the only built-in option for higher precision floating point (if it's not the same as float). Otherwise, you're in the realm of hand-coding numerical routines.

#

Why do you need all those digits? Sometimes it's possible to adjust your approach so you can work around the limitations of the environment more easily than hand-coding your own extended-precision math.

pastel citrus Nov 12, 2019, 4:33 PM

#

it's a gps location (lat-long) that's why

#

i want to show distance from 2 different locations

#

with 2 LEDs

eternal cliff Nov 12, 2019, 4:33 PM

#

And you need accuracy down to a few meters?

pastel citrus Nov 12, 2019, 4:33 PM

#

if i am close to one location that LED is green. if not orange, if too far red.

#

No, 100m accuracy is good enough

#

But, the more precise the better, because averaging gives similar numbers

eternal cliff Nov 12, 2019, 4:35 PM

#

It might be worth converting the integer and fraction parts separately, then subtracting the integer parts and applying the difference to the fractional difference.

#

That way instead of having to deal with (say) 181.338571 - 181.347562, you could scrape off the 181-181 part and then only have to subtract 0.338571 - 0.347562 so you don't waste mantissa on digits that don't enter into the calculation.

pastel citrus Nov 12, 2019, 4:36 PM

#

I'll test it with double, let's see how it works.

#

I will probably do smth like that, first I need to understand how my movements reflect on color range.

eternal cliff Nov 12, 2019, 4:37 PM

#

I may be wrong, but I'm assuming you're doing a Pythagorean approximation of a flat surface so distance = sqrt((lat2 - lat1) ^ 2 + (lon2 - lon1)^2)

pastel citrus Nov 12, 2019, 4:37 PM

#

I still need to map 0 to 100 to HUE from Red to Green

eternal cliff Nov 12, 2019, 4:38 PM

#

There are a few places you can just grab the hue mapping code.

pastel citrus Nov 12, 2019, 4:38 PM

#

I will need this difference to become an integer in the end. Oh, I'll check that tomorrow morning during workshop (in 4 hrs). AU time is pretty late at the moment

#

no, double did not help

#

My code has another issue

#

Either atof function, or strchr somehow gets me shortened numbers

eternal cliff Nov 12, 2019, 4:41 PM

#

strchr() just finds the comma, but atof() has limited precision.

#

Since you'll want an integer result ultimately, it might make sense to use integer math. You could do something like multiply the fractional part by as many digits of precision as you require and treat them as integers.

pastel citrus Nov 12, 2019, 4:43 PM

#

The number is there, the serial print was the issue.

eternal cliff Nov 12, 2019, 4:43 PM

#

Using the example I had above, you could do something like treat 0.338571 as the integer value 338571 instead and store it in a long variable.

#

Ah, good catch!

pastel citrus Nov 12, 2019, 4:46 PM

#

one of my coordinates is AB.91

#

so that's why I was a bit scared of it, but for presentation purposes, I'll go with that method probably.

eternal cliff Nov 12, 2019, 4:48 PM

#

I'm not sure what AB.91 is, maybe a Maidenhead grid square?

pastel citrus Nov 12, 2019, 4:49 PM

#

no, no ... it is close to the next number

#

that's why i want to keep integers alive, just in case i move a lot

#

maybe also being able to set new parameters could be nice too

#

it will be a shoulderbag with led's showing distances from different locations

#

it's been too ambitious for a beginner project to go for BLE + iOS + ArduinoJSON + adafruit.io all at once, but it's been a pretty fun process so far.

#

And I can't thank enough.

eternal cliff Nov 12, 2019, 4:52 PM

#

It's a tricky problem, as floating point numbers can have cumulative errors when doing calculations, but you have to do a bunch of bookkeeping if you use integer math (which doesn't have the cumulative errors).

#

It does sound like a cool project.

#

I did find this useful page for doing hue/saturation/value color calculations just using integer math http://www.vagrearg.org/content/hsvrgb

pastel citrus Nov 12, 2019, 5:04 PM

#

I'll definitely check this. I am planning to use 4 neopixels and maybe fast led. I'll have a look at it after a 3hr nap, I am more or less ready for the demo.

#

@eternal cliff Thanks big time.

#

@royal rapids Thanks a lot, I have been working as a ux designer for quite some time and already took some notes for the Bluefruit LE App. If you'd like to have some feedback, I can supply my own user-stories for ux research, or help with some heuristic ui-related feedback as well.

pastel citrus Nov 12, 2019, 5:56 PM

#

@eternal cliff I've got one final issue apparently, since I am struggling with debugging it.

#

I am using the same serial connection to get 3 ArduinoJSON deserialisations

#

const char* feeds_twitter = doc["feeds"]["twitter"]; // "49589" const char* feeds_insta = doc["feeds"]["insta"]; // "392" const char* latlong2 = doc["feeds"]["latlong"]; //actual latlong string

#

there's a loop and somehow the board gets stuck.

#

it happens to have problems with uploading too

pastel citrus Nov 12, 2019, 6:16 PM

#

it probably looks for the comma and cannot find it

eternal cliff Nov 12, 2019, 6:42 PM

#

The strchr() routine should return a pointer to the comma if it finds it and NULL otherwise. Probably the code should check for that.

pastel citrus Nov 12, 2019, 6:43 PM

#

I solved it with an if/elseif/else loop for 3 conditions. Now, it seems to be good, but it's been a bit heavy on the board, it started to struggle for uploads. Restarted the computer, let's see how it goes. This could be the final logical iteration.

#

The rest will be colouring LEDs, which I am not worried about as much as this part.

#

I cannot see the port, it was making a sound. Now, I don't see the port. Is it possible that I messed the board, or my port?

#

Is there a way to check this?

eternal cliff Nov 12, 2019, 6:48 PM

#

Which port, the serial port used to program the board? Or the port the GPS is connected to? Or something else?

pastel citrus Nov 12, 2019, 6:52 PM

#

usb, serial board

#

I cannot see it after hard restart either

#

but the lights of the bluetooth & c playground blink, the energy comes

#

a mouse works as well (when i connect one)

#

arduino starts extremely slow as well, waits long at initialising packages screen

#

this looks really serious,

#

i will look through forum as well, but if it's a common issue, i'd appreciate any advice.

pastel citrus Nov 12, 2019, 7:31 PM

#

solved it

eternal cliff Nov 12, 2019, 7:34 PM

#

Oh cool!

#

Note that I simplifed the math somewhat with lat/lon to distance. While latitude has a (more or less) fixed distance per degree, longitude's distance per degree scales with the cosine of the latitude 🙂

I have a couple sensors that push a reading every 15 minutes to the site, but every couple of days (no obvious pattern) I can't seem to push for a 7 hour stretch. Is this just me?

#

The code is just a simple python while loop that would need to be manually restarted so it a crash that is causing this.

i.e: what, exactly, was the crash about. I can help debug with that 🙂

@royal rapids there was no crash. I meant to type "so it can't be a crash"

royal rapids Nov 18, 2019, 8:42 PM

@ruby radish Are you using Adafruit IO Python?

ruby radish Nov 18, 2019, 9:15 PM

#

yup

ruby radish Nov 18, 2019, 9:34 PM

#

I guess it could be an issue with the connection to the sensor if I am the only one having issues with pushing to Adafruit IO.

royal rapids Nov 19, 2019, 3:08 PM

#

@ruby radish Could be - it's difficult for me to help diagnose without a log/error :\

ruby radish Nov 19, 2019, 3:18 PM

#

@royal rapids Right, that's why I wondered if something had been happening with the AdafruitIO site, because as far as I can tell, my script is working, and I am getting sensor readings, but sometimes I just can't seem to push them to the site.

Thanks for your help!

@royal rapids Is there something in IO+ that if you delete all the feeds in a dashboard there are some sort of hidden artifacts (for lack of a better term) that impact layout of the dashboard when you add new blocks to that dashboard? I'm probably not describing this well but it seems like something is going on that manifests itself when adding a new block or rearranging block to optimize the view on a phone

royal rapids Nov 19, 2019, 3:21 PM

#

@ruby radish if you get an error, lmk and we'll debug. i dislike bugs as much as you..probably more 😄

#

@south gust When you delete all the blocks in a dashboard, there are "invisible blocks"?

#

Do you have an example of this occurring or a screenshot?

south gust Nov 19, 2019, 3:28 PM

#

The invisible blocks description is pretty accurate but I've gone nad deleted the old dashboards and started over with new since I sort of realized something wasn't quite right

#

@royal rapids A recent example is that I was using a combination of gauge blocks and trend blocks intermingled and when I deleted the trend blocks and positioned the gauges at top of dashboard on laptop where everything looked fine, on phone I would have to scroll way down page before I got to gauges. Deleted complete dashboard and redid with gauges at top on laptop, and they present on top on phone without having to scroll down.

royal rapids Nov 19, 2019, 3:46 PM

#

hrm, that is odd. I'm going to try to replicate later this week and file a bug report to see if someone get sto it before I do

south gust Nov 20, 2019, 12:57 PM

#

@royal rapids Is there a way to add other icons to the ones you can use in a gauge block on IO? Things like electrical symbols just as an example.

royal rapids Nov 20, 2019, 2:16 PM

#

@south gust as of now it's fixed to the two icon sets we use (you can add an image block and customize that, though. same with the customized headers).

south gust Nov 21, 2019, 5:29 PM

#

@royal rapids Is there a way to position the icons associated with the gauge block to position the icon more appropriately? I'm using gauge block for temperature and there is an icon w:Farenheit but unfortunately it positions to left of the numeric value rather than to right of value which is how temperature is typically written. Doesn't matter for picture type icons like a thermometer.

I'm making a project that uses the vs1053 adafruit shield to play music for a spinning christmas tree I made. I have LEDS attached to the tree, but I want them to interact with the music. For example, the lower tier of lights would pulse every time the bass is hit on a drum set in a song, and the upper tier would blink everytime the hi-hat is played. How would I got about doing this? In my head it seems simple but I don't know how to code it. Any help would be appreciated.

Hi all! I am new to Adafrui IO and I don't understand exactly what means that the free account has 30 days of data storage. Does this mean that if I create a feed, it will be removed after 30 days or that the free account lasts for 30 days? Thanks in advance 🙂

fresh anchor Nov 25, 2019, 10:10 PM

#

Hello, That means a-io will store the data you send to it for 30 days for like data for charts and what nots 🙂 have a great time with io meow.

abstract mica Nov 26, 2019, 5:00 AM

#

the feed won't be removed, but the data you send to it.

#

if you only care about the latest value then it doesn't matter, it's just the history of previous values that is limited

#

@gleaming valley I don't think @royal rapids has resolved that yet. I don't know what your experience has been but in addition to the "invisible blocks" issue I've noticed that if you lay out a dashboard to optimize the space on a regular laptop or PC monitor and then view on a phone it will reorder the blocks like there is some sort of formatting taking place behind the scenes to reposition the blocks for phone screen. Roughly like if you lay out 4 blocks horizontally across laptop called B1, B2, B3, B4,

On phone you get

#

@little siren hi. Yes. I would like to use 2 adafruit adxl345 in my code above, in place of 2 accelerometers i am using. Would you please be able to help me? Please see the above code.

little siren Dec 11, 2019, 12:25 AM

#

@graceful pumice I would read through the primary guide, and study the example code:
https://learn.adafruit.com/adxl345-digital-accelerometer/overview

Adafruit Learning System

ADXL345 Digital Accelerometer

Triple-axis accelerometer breakout with a digital interface.

#

Where is your example code from?

#

The code you provide references the MPU6050's gyroscope. The ADXL345 has no gyroscope.

graceful pumice Dec 12, 2019, 11:49 PM

#

Hi @little siren . My code is not an example code. It is a code written for controlling gaming 's controllers potentiometers with accelerometers and pressure sensors. I have two mpu6050 that are used in that code.
So is there no way to use the adxl345 in place of the mpu6050 because adxl345 has no gyroscope?

Should i get 2 different accelerometers?

little siren Dec 12, 2019, 11:50 PM

#

Getting 2 gyros, or IMUs that include gyros, is probably your best bet.

graceful pumice Dec 12, 2019, 11:52 PM

#

I need something better than the mpu6050 because i in my code , i need to be able to clealy distinguish between calues that result in walking in games from values that result in running in games

#

millis() - timer > 750 , results in walking

#

millis() - timer < 700 results in running in game

#

'''if ((step == 1 || step == 2) && millis() - timer <= 700) { if (freq > 1) { servo.write(70 , 20); angle = 70; } else { servo.write(78 , 20); angle = 78; } freq++; } else if ((step == 1 || step == 2 && millis() - timer > 750)) { servo.write(78 , 20); angle = 78; freq = 0; } timer = millis(); '''

#

Pratically the servo rotates to an angle of 70 when my steps are fast and hence the millis timer is <700

#

Instead it rotates to 78 , when my steps are slow and hence millis timer is >750

#

The problem is that at times, even when walking, i get a few values that go <700 and the opposite. So there is at times no clear distinctiom between the 2 thresholds

You can probably fix that in software, I suspect you'd have similar issues with other sensors.

Actually, I'm not sure IO supports QoS. Perhaps someone with more knowledge of the broker side could chime in?

Adafruit IO supports a QoS of 0 or 1, it does not support a QoS of 2.

I've had success with pub and sub to adafruit IO through ESP8266, is there a way to use the AdafruitIO_Feed object to report the IP address it is connected as? All the WiFi is done "internally" within the MQTT library and I can't find methods to report it. (If I'm just using Wifi sketches the IP address is easy to find).

royal rapids Dec 27, 2019, 2:54 PM

#

@silver spoke You can't use the Adafruit IO Arduino lib's methods to report the local IP Address.

#

Since Adafruit IO Arduino manages the WiFi client, you'd need to add it directly into the wifi interface here: https://github.com/adafruit/Adafruit_IO_Arduino/blob/master/src/wifi/AdafruitIO_ESP32.cpp

GitHub

adafruit/Adafruit_IO_Arduino

#

Since each client is module specific, it'd be different per-board. Though I could probably expose them through an AdafruitIO_IP call.

Hmmmm. I seem to have a difficulty with IO. I wrote some code to upload to a feed, and I kept getting an error about strings not having an encode method. I assumed I had misconfigured secrets.py, but on careful inspection it looked ok. Then I tried running adafruit_io_simpletst.py from the GitHub repo at Adafruit_CircuitPython_AdafruitIO/examples/mqtt/ and got the same errors. In order to try to figure this out, I just went to the REPL, created a string, and tried the encode method: ```
Auto-reload is on. Simply save files over USB to run them or enter REPL to disable.
code.py output:
Traceback (most recent call last):
File "code.py", line 93, in <module>
File "adafruit_minimqtt.py", line 121, in init
AttributeError: 'str' object has no attribute 'encode'

foo.encode('utf-8')

So then I went to the bundle source and looked at adafruit-circuitpython-bundle-py-20191221/lib/adafruit_minimqtt.py and checked out line 121. It looks like this:
118 self.user = username

120 self.password = password

@abstract mica That would be unfortunate, since it means people wouldn't be able to use the STM32F405 with AdafruitIO....

hey guys, apologies I'm very new to this. A silly question about IO, so basically this is a plotting mechanism , i get that.
To feed the data, in to IO i need to somehow to convert the sensor output to MQTT and point to IO?
Basically I got a Enviro + sensor for Raspberry Pi and would like to plot the graphs or the temp, humidity ect ect.
Would the first step be to learn MQTT and use them to push the data to the IO feed?

The good thin about that project is that you can use the base concepts for sending most any type of sensor data to IO. It creates the feeds and everything.

Is there a way to send NOAA CO-OPS data to IO? I took a look at the PyPortal tides project and it didn't really seem to fit the bill in that it appeared to be doing a bunch of the work that is already built in to IO. I'm guessing I need to do this via MQTT but have not succeeded in finding any examples of working through that process.

sacred depot Jan 1, 2020, 4:23 PM

#

What is NOAA CO-OPS? Is there a regular server for it? Is it text based?

#

https://tidesandcurrents.noaa.gov/api/ like that?

sacred depot Jan 1, 2020, 4:40 PM

#

Here's a quick wget based script to use that API:
https://termbin.com/p49b

(linux-centric approach; any unix-like shell that has wget should be able to run it)

#

(I have no idea how to enhance the data-getting URI; just followed the first example on that API doco page)

dusky shuttle Jan 1, 2020, 4:41 PM

(Also UINX-centric approach: make it modular and default to stdin/stdout, then pipeline it with existing tools.)

#

hey I have a adafruit raspberry pi prototyping plate, and I could use some help soldering it. I have few questions.

#

For one, the input pins to connect to the raspberry pi are very close to each other. When soldering i assume the goal is to make sure the solder does not touch the adjacent pin?

#

I have a resistor that i will have to connect to the other side of an op amp. I see singular holes that are not touching other holes, unlinke the center ones that appear in parallel strips. The question is how can I connect the singular holes to each other? My plan put one resistor lead in the single hole, put a jumper in the adjacent hole, solder the two so they are touching(this is the part im most concerned over), finally solder the other jumper end to the other side of the op amp on a parallel strip. Does all of this make sense? for essentially connecting two ends of an op-amp through a resistor?

ocean eagle Jan 1, 2020, 6:36 PM

#

@pale tapir I'm not an expert on soldering, but 1) typically you don't want to solder adjacent pins together, 2) about half of that plate is configured similar to a regular breadboard (where rows and columns of holes are connected with copper), and the other half are all separated holes. As such, if you haven't already done a breadboard version of this circuit, I'd start there. That would require no soldering, and just some jumper wires from your Pi to the breadboard itself. Once you have it working on the breadboard correctly, it'd be a pretty simple jump to the plate.

I don't have the slightest idea how to get JSON data in to IO as via this screen capture

📎 unknown.png

#

In that PyPortal Tides project it shows the raw JSON data but then didnt seem to really show what they did with it plus there were a lot of dissimilarilities between drawing the graphics and fonts on a dedicated screen and all of that effectively already built in to IO.

I've poked around with that tides and currents site a fair amount and have certainly poked around the IO site but in general I am a rank newbie at the software end of things. Hardware doesn't intimidate me but trying to figure out how to take disparate data systems such as NOAA's tides data and roll it over in to IO is pretty daunting especially when I haven't the slightest idea where to start.

#

I need like JSON or MQTT FOR DUMMIES or something similar.

sacred depot Jan 1, 2020, 9:32 PM

#

Yeah I don't know either of those. This is the first time I've looked at a .json and was surprised it was ASCII ;)

#

I would probably start with perl myself, as I once knew it (some).

#

Just thought it might help with JSON -- a bit....

south gust Jan 1, 2020, 9:49 PM

#

This is trying to aggravate me. (Trying to post the NOAA picture is what is aggravating) The NOAA site generates json itself. Shouldn't I be able to take the JSON direct from the NOAA site and send it to IO, we'll disregard the fact that I don't know how to do that yet.

#

The PyPortal is about that ESP32 hardware?? that I know nothing about?? I think for one thing

#

It's hard for me to sort out the JSON stuff from all the other hardware stuff that I am also unfamiliar with is the just the real quick pass look. I'll look at it in depth later.

#

@keen dirge I typed in JSON in the LEARN section adafruit and this is what I get. https://learn.adafruit.com/alltheiot-protocols/adafruit2-json

#

Where I fall down is in converting that to a usable feed that will draw the same sort of trend line that is resident in the the NOAA web site.

For some reason I was unable to paste the picture showing the web services button on the NOAA site that has the JSON data

I'll try and look for an external json feed example coming to IO

I meant what is the data transport mechanism? My system is disassembled right now but I'm trying to get a better understanding in general of how systems send and receive data. I set up to have a feed to WU but as I said it is in parts right now.

dusky shuttle Jan 2, 2020, 11:14 PM

#

Ah! There's an API reference. You just use the urllib calls. You build a URL the submits all the collected data. I'll dig out the reference API for you.

south gust Jan 2, 2020, 11:15 PM

I saw that in your github code. It's more of a process question for me in that I want to better under stand how my data is getting to IO+ in the same way

dusky shuttle Jan 2, 2020, 11:22 PM

#

Uh oh. It looks like the upload protocol API docs aren't there anymore. I'm going to have to start looking for alternatives. The way I would do it in IO+ is to create a group. Then create a feed for each data element, and add that feed to the group. Then just use the AdafruitIO Python library to handle the connections and data submission.

#

Is that what you meant?

south gust Jan 2, 2020, 11:24 PM

#

Well, I can create feeds and groups and send them to IO all day long. More just trying to get a better understanding as to whats going on under the hood as they say.

#

Kind of like most people dont't care about how the internal engine in their car works. they just want it to get them from point A to B when the key turns. I'm the one who wants to know how the engine works.

I actually don't know how AdafruitIO is architected. It would be very interesting to know. #I'llSignAnNDA

south gust Jan 2, 2020, 11:33 PM

My assumption is that IO is more restrictive as to what data it will accept out of the box. Based solely on the weather station dropdown on WU and people who are not nearly as technically proficient who are expecting a plug and play interface to WU.

Hey guys- very simple question. Got an Adafruit Feather 32u4, and a lipo battery connected. There is a charging indicator light when the battery is charging. Does that light go off when the battery is full?

@near summit that's not really an AdaFruit IO question, but here goes: the LED is connected to the "STAT" pin of the MCP73831 battery charging control chip

The data sheet for the chip states "STAT is an output for connection to an LED for charge status indication." which isn't particularly forthcoming

I have a fair amount of garbage hitting my MQTT server. I want to send '/weather/#' to adafruit.io. I have configured a bridge with the line 'topic /weather/# out 0 "" <username>/feeds' which as I understand it should publish to '<username>/feeds/weather/humidity', '<username>/feeds/weather/temperature' and so forth. I am seeing no errors, but likewise, I am seeing no data. I suspect it has to do with the 'composite' i.e. /weather/humidity name. I this the case?

hushed sigil Jan 3, 2020, 7:21 PM

#

I don't think you can bridge directly from a broker to AIO. I think you have to use the API. This "how-to" uses a python script to pass the data over from the local broker to AIO: https://learn.adafruit.com/manually-bridging-mqtt-mosquitto-to-adafruit-io?view=all

Adafruit Learning System

Manually bridging MQTT to Adafruit.IO

#

I also use a python script running in a docker container on a digital ocean droplet that acts as a bridge. But mine goes from AIO to my mosquitto broker. I can do things with IFTTT like, "Ok google, Light Red" and a light turns red....

#

Or is that what you mean by "bridge" a script reading your MQTT topics and sending them to the AIO feed?

hollow crown Jan 3, 2020, 8:05 PM

#

What I am trying is discussed in the 'Broker-to-Broker Bridging' section of that article. I am aware that the example is not intended to be a working file (not the bridge_atetempt_unsubscribe option!) but rather a starting point. I know I am connecting and forwarding info because I can see the packets with wireshark. I can generate errors in the Monitor by sending malformed topic names. It is one of those SO close things.

hollow crown Jan 3, 2020, 8:28 PM

Hi

#

Does "Toggle Blocks" on a Dashbord send messages to a listening device when clicked?

hushed sigil Jan 6, 2020, 1:17 PM

#

@jolly nymph Yes, a toggle block will send a message to the feed, listening devices on that feed should get the message, and perform whatever logic they are programmed to do when they receive the message.

#

I have an "On/Off" toggle on a dashboard that will send "ON" or "OFF". What's cool is if something else sends "ON" or "OFF" to the feed, the toggle will dynamically update to show the correct status. Like a ghost flipping the switch!

Could be the power supply to the relay board is wrong, or you're using a different I/O pin than the relay board is configured for.

really? power supply is 5v....so what to change in code that affects chaning I/O pin?

eternal cliff Jan 17, 2020, 6:07 PM

#

You'll need to find out which I/O pin your relay board uses, and how your ESP board defines that pin, and use that.

#

Also, most relay boards have a separate power supply input (or even two), if the the interface power input isn't connected, the LED and relay won't operate.

#

You're right about the #define: that is what you would need to change if your relay board uses a different I/O pin.

violet coyote Jan 17, 2020, 6:20 PM

#

so i need only to define relay 0 insted of 2?

eternal cliff Jan 17, 2020, 6:20 PM

#

I'm guessing. I don't know enough about any of your project to be sure, but it's worth a try, especially since you said the instructables code (from which I pulled that line) did operate the relay.

violet coyote Jan 17, 2020, 6:21 PM

ok, i will try it tomorrow and will update you..thanks 😉

hi @eternal cliff you were right....everyhing is working now like a charm.....problem was pin number....thanks a lot

I'm glad you figured it out

tulip gust Jan 20, 2020, 10:09 PM

#

heya, I'm trying to set up a boolean feed on adafruit IO for a circuit python MQTT client I have.

I'm able to successfully send a range of data from a potentiometer, but when I try to send a button's state the data doesn't show in the feed on AIO.

That said, there is a reaction. Before I push the button and send the message the y values for the button feed show:

📎 Screen_Shot_2020-01-20_at_4.07.25_PM.png

#

but once I push the button the values disappear

📎 Screen_Shot_2020-01-20_at_4.07.35_PM.png

#

so it's like AIO received the message but something goes wrong. I was looking for an error log but I didn't see one. Is there a good way to figure out what's happening?

#

also, the state machine code I'm using to monitor the button looks like this:

    
    if (now - bigButtonLastNow > bigButtonCheckInterval):
        if bigButton.value != bigButtonStoredState:
            bigButtonStoredState = bigButton.value
            print("big button value: ", end="\t")
            print(int(bigButtonStoredState))
            mqtt_client.publish(feed_big_button, int(bigButtonStoredState))
        bigButtonLastNow = now

#

I was getting errors on the controller side when I tried to send booleans so i'm casting the bools to integers (don't know if that's a problem)

I've been tweaking code to send temperature and battery level readings to Adafruit IO feeds. Those had been working for quite some time, but I was having trouble with the data seeming to be incorrect. I've tweaked the code to try to correct the data, but haven't touched the lines of code sending data to my feeds. BUT, I suddenly seem unable to send data to my feeds. I've tried deleting the feeds... I've tried restarting the code... nothing seems to work. Is there anywhere I can look to see if I'm actually getting a connection to AdafruitIO?

tulip gust Jan 20, 2020, 10:27 PM

#

blergh, well the feed definitely received messages. I sent up a simple counter and forgot to slow down the interval 🤦‍♂️

📎 Screen_Shot_2020-01-20_at_4.26.48_PM.png

#

still not sure why I'm not actually seeing the data on the dashboard

#

hmmmmmmm this is interesting, so I'm using adafruit IO to relay communication from a controller I'm building to a node server on my laptop. While the data doesn't show in the adafruit io dashboard it does come through to my node server mqtt_client

#

📎 Screen_Shot_2020-01-20_at_4.33.18_PM.png

it would be nice to see it in the dashboard, but if the relay is happening I can at least move forward

hey @royal rapids. I'm not totally sure. Yesterday I stood up a node server and put a broker on it (the final version of the project I'm working on is going to be on a local network).

That said, when I get into the office in the afternoon I can swap it back and check to see if it's still happening. I'll let you know

Hi, I have a value problem with spg30, using the example of "spg30test" terminal serie the values change but in my dasboard it remains the same using the example of the library "adafruitio_22_environmental_monitor . how can I make it work better?

@graceful adder Are the names of the feeds in your dashboard and the code the same?

fluid hollow Jan 23, 2020, 3:31 PM

#

@royal rapids I deleted my feed and created a new one with a different ID and I got it to work. I don't know why it wouldn't work with the previous ID.

#

I apologize... I don't know my way around discord yet. The above is in reference to my post a few days ago regarding inability to reconnect to a feed.

#

Thanks for following up.

no problem, discord doesnt yet have threaded convos

glad you got it working, i'll be on here during the day if you have any other q's or issues 🙂

tulip gust Jan 23, 2020, 5:57 PM

#

@royal rapids sorry, yesterday got away from me. I switched over to the adafruit io broker just now and it looks like the data is showing in the feed

📎 Screen_Shot_2020-01-23_at_11.55.57_AM.png

#

a quick troubleshooting question: is a qos setting of 1 synchronous? Reading about mqtt it didnt' seem like it was (I thought the broker would message back down once it got the message from the client, but it didnt' seem like the client would wait), but in practice it seems like the client will wait for the broker to respond

#

is this expected?

#

(trying to make sure i understand all of the concepts and tools correctly)

eternal cliff Jan 23, 2020, 6:32 PM

@violet coyote You've asked this before. It seems possible that there isn't pre-existing code to do exactly what you're looking for, so you may have to combine code to retrieve actions with code to operate the relay. The CH340 isn't really part of the equation.

violet coyote Jan 23, 2020, 6:36 PM

no, i asked for relay 1ch, but now i have 2 channels (2 relays) on the board.....

The code modifications would depend on how you want the second relay to operate. If you just want both relays to do the same thing, it's a fairly easy change, just replicate the relay code and define a second relay pin. If you want independent control of each relay, you'll have to duplicate more of the control code as well.

violet coyote Jan 23, 2020, 6:43 PM

@eternal cliff i want each relay to turn on/off lamps ( i have 2 lamps, one relay one lamp) but when i upload this code which was working with 1ch, nothing is going on....both relays dont react....i opened feeds on adafruit dashboard

eternal cliff Jan 23, 2020, 6:44 PM

#

It may be that the new 2-channel relay board needs to be configured to the proper pin(s), or the code needs to be configured to send signals to the pins that the relay board uses.

violet coyote Jan 23, 2020, 6:45 PM

probably...but i dont know how to do that...can you help me?

As far as I can tell (that page isn't very informative), at least one of the relays on the 2-channel board should operate with the same code that worked with the 1-channel board.

violet coyote Jan 23, 2020, 7:36 PM

#

yes, i think it should worked....but how to check that relay is working...maybe something is wrong with the relays on the board, like here, please watch video https://www.youtube.com/watch?v=OCWvhxCiyw4

@royal rapids yes the names are identical . the values remain fixed on 400 PPM and 0 PPB

@quiet steeple Yes, but the I/O pins might be numbered differently.

violet coyote Jan 24, 2020, 3:59 PM

#

so nobody wants to help or dont know how?

eternal cliff Jan 24, 2020, 4:45 PM

#

We don't know how: all we know about the 1-channel relay board is guesswork, and we know next to nothing about the 2-channel relay board, so there's really not much to go on. The fix you did for the 1-channel board might work, we don't have any way to know. The fix in the video (whatever it is) might work, we don't have any way to know.

quiet steeple Jan 24, 2020, 5:28 PM

#

@eternal cliff thank you for your help. I did realize the pins are different. That being said in the Arduino code it says data pin 2 does that mean pin 2 of the micro controller and I have to figure out what it’s broke out to?

eternal cliff Jan 24, 2020, 5:30 PM

#

You pretty much have to figure out what it's broken out to. There's generally no correlation between physical pin numbers on the IC itself. Arduino arbitrarily numbers I/O pins 0, 1, 2, etc. but different board makers assign the numbering differently. Worse, some board makers (including many ESP boards) use different nomenclature like D0, D1, D1 instead.

quiet steeple Jan 24, 2020, 5:35 PM

#

Yeah I was noticing that last night when I was playing with a cheap esp board. I’ve only used Adafruit stuff before so I have been spoiled with the great documentation

eternal cliff Jan 24, 2020, 5:37 PM

#

Sometimes you end up having to write a program to send signals to various pins and write down which pin answers to which index. However, I usually just dig into the Arduino installation, find the pin definition file for that target, and read off the pins that way.

quiet steeple Jan 24, 2020, 5:39 PM

#

That’s so smart. I was just going to try an example sketch that turn on an led or something like that and test each pin.

eternal cliff Jan 24, 2020, 5:40 PM

#

Sometimes you'll find something like this, which tells you that it's mapped the D0, D1, etc. pins to numbers that are defined in another file (../generic/common.h), so there's another step to it

@light flare If you're timing out, make sure you're calling MQTT_connect() at the top of each loop to keep the MQTT connection active

Is there a way to programmatically create a feed in a group (specifically in the Python interface)? When I attempt to use the group subfeed naming scheme (groupkey.feedkey), it creates a feed with the key 'groupkey-dot-feedkey' instead. I tried setting the 'key' attribute of the feed separately from the name (f = Feed(name='SomeName', key='groupkey.feedkey') but when I used create_feed, it just ignored the 'key' setting and left the keyname as the groupname. Help!

would it be possible to make the toggle button in AIO work in both directions?
For example: When you toggle it from AIO, it will ignite a lamp or whatever. But programmatorically turn it out after lets say a minute or when a certain temp. is reached and accordingly move the toggle to the right state (on or off).

#

you can't publish and subscribe to the same topic/feed.

#

but how to flip the toggle button online if the same toggle is used to turn the light on or off

royal rapids Feb 13, 2020, 1:59 PM

#

@sacred depot The toggle element reflects the state of the feed. You can toggle it by writing to it the feed.

#

or by clicking the button, which writes to the feed

sacred depot Feb 13, 2020, 2:09 PM

#

I know. But I also have a subcription of the button, SO I'm not able to publish to AND subcribe to the feed. It throws an error.

Do you have an oscilloscope or logic analyzer in order to have a peek at the SPI signals to verify they are happening and look reasonable?

No but the lsm9ds1 works with my other boards fine

neat charm Feb 14, 2020, 6:24 PM

#

I thought you said you were using SPI, not I2C.

#

Is the driver on the nRF using I2C?

There are a couple of CS pins on the LSM9DS1 to select the interface. Does your breakout board pull them properly to choose I2C mode?

Okay, that all sounds reasonable. I guess the next step is to turn to the software side. How are you initializing and testing it?

@sacred depot You should be able to subscribe and publish to the same feed. I do it all the time. I have a python script that listens for "On" or "off", when it receives either, it turns on/off a relay. If it gets "On" it spawns a new screen session with another python script that waits 20 minutes, then publishes "Off" and kills the screen session. The listening script then receives the "Off" command and turns off the relay, my AIO Dashboard receives the "Off" command and the toggle goes to off...

Noob to adafruit-io... Using Python I am able to insert data into a feed and use the data object sd = data(value=10, created_at'YYYY/MM/DD HH:MM:SS'). when I insert a datetime it converts it to UTC time. Is there a way to make it accept the time as it is entered or should I just plan for the conversion?

royal rapids Feb 18, 2020, 2:15 PM

#

Hi @pallid bane - You should plan for the conversion, IO uses UTC time.

#

I could modify the created_at parameter in IO Python if you file an issue here with how you'd want to use specify the timezone to the data object: https://github.com/adafruit/Adafruit_IO_Python/issues

@royal rapids Thanks for the reply. I see the value in having the ability to define the timezone you are posting for. I'll post an issue. Thanks again.

I'm trying to understand how the following three ways of controlling brightness interplay:

the brightness in

pixels = adafruit_dotstar.DotStar(clock, data, n, brightness=1.0)

the color level (I think it's supposed to be a UInt8 so 256 discrete levels) in

pixels[0] = (0, level, 0)

and the discrete levels of intensity in

pixels[0] = (0, level, 0, intensity)

Do you know what the set of possible values is for each of these three settings? And if we know them, are they simply "multiplicative"? Say brightness in the DotStar function can be any value in 0:0.01:1, color level is 0:1:255, and color intensity is 0:0.01:1, then, excluding brightness zero, do we therefore have 99 × 255 × 99 = 2499255 discrete brightness levels?

Any insight would be useful, thanks!

keen dirge Feb 21, 2020, 11:23 AM

#

@cedar valley In the source code for the Circuitpython Dotstar library,
there are some comments that may be helpful.https://github.com/adafruit/Adafruit_CircuitPython_DotStar/blob/master/adafruit_dotstar.py#L145 https://github.com/adafruit/Adafruit_CircuitPython_DotStar/blob/master/adafruit_dotstar.py#L257 It looks like the "brightness" set at initialization is uses as an ovrerall "scale" factor on the actual "level' (see second link) where the "intensity' as you use it is used by the dotstar chip to adjust the PWM control as noted in the first link. I hope that helps.

@shell star @modern beacon I am trying to get the Adafruit Bluefruit LE app to subscribe to an MQTT feed on Adafruit.io. I have seen it mentioned that this can be done but have yet to find exsample code or info on how to do it. I have got it publishing to A.io without issue using the following guide: https://learn.adafruit.com/datalogging-hat-with-flora-ble

Can someone point me in the right direction of a guide or exsample of using MQTT subscribe with the BLE app?

tiny needle Feb 22, 2020, 9:46 PM

#

I have followed the information on this guide, but still can not get info from Adafruit.io to the Bluefruit LE app. Things I am not sure of are: do if phrase the feed as (UserName)/feed/(feed name) or (UserName)/f/(feed name)? Also, what is the Action section for under Subsctibe? I see the options for Local Only or Transmit. What needs to be selected? Do I need to be using SSL for this to work or will port 1883 work?

tiny needle Feb 22, 2020, 11:00 PM

#

So I got data comming into the controller Arduino code by Setting the Subscribe topic using (UserName)/f/(FeedName) and the Action to Transmit.

Now I just need to figure out how to get the message from the UART buffer so I can use it in the loop.

vagrant fossil Feb 24, 2020, 4:25 AM

#

Does the adafruit wifi library auto reset if it doesn't connect? And the retry.

#

@tiny needle look at some of the subscribe example

shell star Feb 24, 2020, 5:39 PM

@tiny needle I've never done it before but @royal rapids may know

tiny needle Feb 24, 2020, 9:10 PM

#

@shell star and @vagrant fossil. I got it all figured out yesterday and now have it working for the Feather Blufruit LE, Huzzah ESP32, and the M5Stick-C

#

Basically this will make it so you can have a wearable device that connects to MQTT and IFTTT without having to use a mobile WiFi hotspot or a GSM/LTE module. I am hopping to do a learning guide on it soon.

Hi all from the UK! I’ve been putting together this display with the Adafruit MQTT library which displays data (originally from Adafruit IO but now a local combo of Mosquitto and Node-RED) from an array of BME280s.
This maybe a case of a lack of my understanding/what I want to do it’s possible using the library but worth a stab.
I’d like to be able to send/receive data (over serial) from the Nextion display while also keep an eye out for new MQTT messages from the broker.
My understanding is that if I’m not in this section of the code then I don’t hear messages – if true is there another library/technique that I might be able to use to keep an eye out for messages while still having a responsive display?
while ((subscription = mqtt.readSubscription(5000))) {….}

tiny needle Feb 24, 2020, 10:38 PM

#

@sacred depot I tend to us the PubSubClient Library (https://github.com/knolleary/pubsubclient) when connecting ESP devices to Mosquitto servers. It is set up to recive messages rather like an interupt so the only time I miss a message is if the wifi is spotty, but then I can use QOS 2 and that works well in even the worst wifi. All of your message handeling is in the Callback section, but try to keep your code as minimal as possible otherwise you get a bit of lag. I tend to just pass the incoming message to a veriable that then gets prossessed in the loop.

I just got a Nexton display not long ago though I have yet to connect it to anything yet. If you have not heard of the HA Swich Plate project, I sugjest cheking that one out as it is along the same line and they could help guide you more. https://github.com/aderusha/HASwitchPlate

Ok I think I figured it out. I made another feed to test, and IO made a group called Default to put it in. When I went back to the Dashboard both feeds showed up. I guess I somehow deleted the Default group and the dashboard feed picker didn't like that?

@icy canopy @shell star It's a bug. I've seen that happen before, but wasn't sure how it occurred for the user. Thanks for taking good screenshots and details - I'm going to add an issue to our bug tracker to make sure it gets looked at.

@shell star Is is possible to use the gyro, mag and accel values on the Feather Sense to compute measurement.orientation or computed for me somewhere?

@queen reef may know. I've not done any of that

queen reef Mar 11, 2020, 8:53 PM

@icy canopy, yeah. There's a quaternion service available that will give you the orientation. I used it in a guide that I wrote here last week: https://learn.adafruit.com/bluefruit-dashboard-web-bluetooth-chrome. There's also some more implementation details in https://github.com/adafruit/bluetooth-low-energy.

@queen reef I downloaded the firmware for the Sense and installed it. But its for the nRF Express board when I look at the Info_UF2.txt file?

queen reef Mar 11, 2020, 9:04 PM

Which firmware did you download?

the middle green button here https://learn.adafruit.com/bluefruit-dashboard-web-bluetooth-chrome/installing-firmware

queen reef Mar 11, 2020, 9:06 PM

Ok, I compiled that one in arduino, so you can probably ignore that file.

It could be because I compiled it while it was so new.

icy canopy Mar 11, 2020, 9:07 PM

ok is that file the bootloader?

queen reef Mar 11, 2020, 9:08 PM

No, it is the Bluefruit Playground firmware. You can get the source from https://github.com/adafruit/Adafruit_nRF52_Arduino/blob/master/libraries/Bluefruit52Lib/examples/Peripheral/bluefruit_playground/bluefruit_playground.ino

It sounds like you may be trying to send the raw base64-encoded data, whereas the library expects a higher-level data format. So you might need to put the image data as the value in a single-key dict or something.

I am getting a lot of name resolution errors connecting to adafruit.io This started just yesterday or the day before (3/20). I haven't changed my code. Am I the only one? Anyone make a good work around? I'm kind of assuming there is some issue with the network that is out of control of Adafruit and myself until people go back to work.

@high estuary re: "Hi, does anyone know how the “Map block” on io works, I am passing lat and long (0.00,0.00) co-ordinates but it doesn’t update to the co-ordinates location?"

#

The Adafruit IO map block uses lat, lon, ele metadata which you pass along with the value.

#

for reference: https://io.adafruit.com/api/docs/#create-data

#

let me know if you have any other q's or help 🙂

high estuary Mar 24, 2020, 2:02 PM

#

@royal rapids the solution:
curl -H "Content-Type: application/json" -d '{"value": 42, "lat": 23.1, "lon": "-73.3"}', do you have any idea why a random value of 42 is passed?

royal rapids Mar 24, 2020, 2:03 PM

#

@high estuary 42 doesn't hold any significance except as an example. Value is a required piece of data to send to the feed

#

lat lon and ele are optional

#

I was compiling the adafruitio_00_publish sketch for my TinyPico (ESP32-PICO dev board) and noticed the sketch, which is quite simple, uses 911090 bytes. That's awfully large. I'm using Arduino IDE.

#

Is is meant to be that large? Or am I loading other libraries I don't need without knowing it.

royal rapids Apr 2, 2020, 1:15 PM

#

@green hull Adafruit IO Arduino is fairly large, but it also loads a few other libraries (Arduino HTTP, Adafruit MQTT, Arduino JSON)

#

If flash size is a concern, you could switch to the Adafruit MQTT library (see here for a MQTT+AdafruitIO+ESP32 Example: https://github.com/adafruit/Adafruit_MQTT_Library/blob/master/examples/adafruitio_secure_airlift/adafruitio_secure_airlift.ino)

@sacred depot Adafruit IO doesn't have the ability to perform client-side packet parsing at this point

The toggle switch in adafruit.io seems to publish on/off in mqtt only when pressed. What might we use to have a persistent on/off status published? If it's not persistent, then you have to keep listening for the event, and might miss it if you're doing something else (I tested it, missed it some times). Or am I not clear on the concept here?

I have been trying to connect a micrometer from Insize (3539-253SA), that normally uses its own Bluetooth-dongle from the same company (7315-2) to communicate its measurements, with a Bluefruit Feather nRF52 via serial UART (115200 baud rate, 8 bit, one stop bit and no parity). In most of the attemts to get it to work I have tried to communicate via the hardware serial for both sending requests to the micrometer and receiving data, in the last attemts I tried with Software Serial that appearently doesn't cope with the 115200 baud rate. Non of the solutions worked. The icon on the micrometer display that normally turn on briefly when using the trigger button on the 7315-2-dongle turns and stays on from the time I send a request to the micrometer. Can anyone help me? I have some sort of documentation in a PDF from the manufacturer if anyone wants to take a peak...

#

Btw, got no data back from the micrometer.

@green hull The toggle switch is persistent, the momentary button is not persistent. Could you make sure Feed History is turned ON for the feed you've connected to the switch?

@royal rapids Thanks. What I expected. And feed history is on. I might be playing fast and loose with the code. With what you just pointed out, lemme review my code. Basically I don’t want to hang out listening - I’ve publishing and other things to do. Alas, won’t be able to get to it until later this evening if at all. Will be back if still unsatisfied with behavior. Thanks for insight!

Thanks! Let me know if you solve it, you may only want to unsubscribe from the feed (you can still publish but not listen)

Hello everyone, I've been messing around with a ESP32 and created an LED clock and wanted to add data from an adafruit.io MQTT topic to it. However all of the examples I found are blocking. Like a while loop that runs for 5 seconds and other such nonsense. Is there a non-blocking way to subscribe to a feed?
Or is this only possible due to the "retain" field that adafruit.io doesn't support?

royal rapids Apr 7, 2020, 6:32 PM

#

@silent lake The Adafruit IO Arduino Library uses MQTT and is non-blocking.

Nice, so just dump the Adafruit_MQTT library and use that one instead.

@silent lake AIO_Arduino uses the Adafruit MQTT library under the hood.

Literally all of them in the library. Example from mqtt_esp8266.ino
while ((subscription = mqtt.readSubscription(5000))) {
if (subscription == &onoffbutton) {
Serial.print(F("Got: "));
Serial.println((char *)onoffbutton.lastread);
}

Howdy! I want to get started with Adafruit IO on my Huzzah32 (ESP32). My project already uses Wifi and talks to a cloud service over https with HTTPClient. I notice that the Adafruit IO examples all seem to need SSID and PASS, but I've already got a WiFi conection using WiFiMulti (multiple sets of credentials). Is there some way to use the Adafruit IO libs/functions to establish a connection over the existing network?

#

I tried to do a bit of searching and finally ended up here to ask. 🙂

languid brook Apr 10, 2020, 3:30 AM

#

After thinking about this a bit and digging through the libs, I hacked my own versions of AdafruitIO_ESP32.{cpp,h}. Since I'm working with just the one hardware device (for now), I coded the typedef into my adafruit_io_config.h along with my AIO Key. I wasn't quite ready to create a fully WiFiMulti compatible version, so my version removes the ssid and pass reference and has a stub for the _connect method, since my wifi connection is managed elsewhere in my program. It seems to be working just fine. 🙂

royal rapids Apr 10, 2020, 3:32 PM

#

@languid brook Interesting, what network configuration do you have where you'd need multiple sets of credentials? Education?

languid brook Apr 10, 2020, 9:01 PM

#

@royal rapids It's a portable device that I might take along to any of several locations with separate wifi (e.g. home, work, mobile hotspot, robotics club, maker space, etc...). Currently, that's not really the case, but it was part of my original plan when I started this project months ago. 😉

royal rapids Apr 10, 2020, 9:04 PM

#

@languid brook Neat - I've had a request from anothe rcommunity member to do something similar with the lib. What are you using to do the multi. connections?

languid brook Apr 10, 2020, 9:08 PM

#

I'm using WiFiMulti, which is in the Arduino examples section for "Examples for Adafruit ESP32 Feature" (WiFi category).

#

Eventually, I intend to store the credentials in a SPIFFS file and write a simple interface to add/edit/delete credentials, so that they're not stored in the code (icky).

#

So... back on-topic... I was playing with Group Publishing last night, but did not have much luck. The data was actually sent to the appropriate Feeds, but then the core would panic and restart the device. The backtrace indicated it was an issue with the Group Callback function.

#

I didn't find any documentation on Group publishing, other than the example with the Adafruit IO libs. My expectation was that using a Group made it so that I could push all 3 of my Feeds with a single transaction, hoping this counted towards reducing my data publishing rate.

#

I didn't test this out with the pure Example, and I do have Tasks running on both cores, so I may have been introducing some complexity.

#

Currently, I have 3 separate Feeds publishing just fine, just like the Adafruit Temperature/Humidity example.

royal rapids Apr 10, 2020, 10:13 PM

#

@languid brook Are the groups in your IO Account?

#

It's odd that it's panicking on the group callback.

#

My expectation was that using a Group made it so that I could push all 3 of my Feeds with a single transaction,

languid brook Apr 10, 2020, 10:14 PM

#

Initially, I created them, but it also seems that they are auto-created when used (I changed the names to compliant characters and they were just created).

royal rapids Apr 10, 2020, 10:14 PM

#

Yeah, AIO_Arduino auto-creates feeds and groups via the HTTP API

#

re: reducing the pub. rate, it won't that way. Groups just store feeds, youd need to publish to a feed within a group.

#

https://io.adafruit.com/api/docs/#groups

#

I created new files and named mine "AdafruitIO_ESP32_ZenCow". 😉

#

My config.h was shorted to the IO credentials, plus:

typedef AdafruitIO_ESP32_ZenCow AdafruitIO_WiFi;
AdafruitIO_WiFi io(IO_USERNAME, IO_KEY);```

#

It seems helpful to have it all in one place for when you only intend to use Adafruit IO, otherwise it would be helpful to decouple the wifi management with the Adafruit IO functions.

#

Since, WiFiMulti already validates ssid's and makes (or fails to make) a connection, I didn't need Adafruit IO to do that for me.

#

On the Group code, I was defining the Group object as:
AdafruitIO_Group *io_group = io.group("zenbbox01");

then was publishing with:

io_group->set("battery-avg", battery_running_average);
io_group->set("battery-max", battery_max);
io_group->set("battery-min", battery_min);
io_group->save();

sacred depot Apr 10, 2020, 11:07 PM

#

@sacred depot I tend to us the PubSubClient Library (https://github.com/knolleary/pubsubclient) when connecting ESP devices to Mosquitto servers. It is set up to recive messages rather like an interupt so the only time I miss a message is if the wifi is spotty, but then I can use QOS 2 and that works well in even the worst wifi. All of your message handeling is in the Callback section, but try to keep your code as minimal as possible otherwise you get a bit of lag. I tend to just pass the incoming message to a veriable that then gets prossessed in the loop.

I just got a Nexton display not long ago though I have yet to connect it to anything yet. If you have not heard of the HA Swich Plate project, I sugjest cheking that one out as it is along the same line and they could help guide you more. https://github.com/aderusha/HASwitchPlate

Hi guys! My fellow project members and I would like to know what is the best way to retrieve data from adafuitIO and feature that same data on an online website. I want to make it pretty, user-friendly and visible for out professors/friends to see. I've seen the API documentation but I'm not sure if that's the right way to do it. Any suggestions?

iron viper Apr 13, 2020, 12:53 AM

#

Well @lunar pelican I just started a small scale personal site to do that, and I am using react and material. (See create-react-app) In poking around the io.adafruit.com site it looks like they use chartjs themselves. I will probably look at that when I get to it.

#

Anyone else here create a website in browser JS only (static resources served, but no 'server' on the backend)? I am trying to figure out how to protect my AIO key. I am making calls right from the browser using fetch and the http api. I have it returning data, but it looks like all calls would need the AIO key. I see a webhooks API is started that could request a token, but that looks like it will only accept data, not pull data. The only thing I can think of at the moment is to put the site behind a sign in with the site chunked so the key isn't sent until a successful sign in. It feels like I need to do something, because a leaked key would enable anyone to delete data/feeds/dashboards, etc, right? Any other ideas?

lunar pelican Apr 13, 2020, 6:59 PM

#

I guess a simpler question is how to feature your dashboard and blocks on a public website other than adafruitIO

iron viper Apr 13, 2020, 7:18 PM

#

Yes, but I don't think that Adafruit exports images of the graphs. You would need to recreate them from the feed api.
