I am using the free option with 4 channels available. I do not have any channels listed, but when I want to create a new channel it gives me an error massage to say that I have used up my 4 channels and need to purchase units to create additional channels.

Hello
I have 3 devices (IOT board using SIM7600 module) sending one value to Thingsspeak. Have been working just fine a couple of years. However 14/11-24 I receive http error code 406 for all 3 devices.
The http get is working just fine when testing directly in the browser (https://api.thingspeak.com/update?api_key=xxxxx&field1=33), the server return the entrie number.
However, when running the same address via SIM7600 I receive - +HTTPACTION: 0,406,0
Any tips for the 406 error code?
Hello, I am wondering why I have over 12000 messages (writes)per day to a channel which I only update all 8 fields every 20 minutes. Or are these statistic timely delayed? Since testing I might have more writes, but now with my ready weather station only every 20 minutes my data will be updated. Wetterbox Channel ID: 2391212 Access: Public Can you explain this to me? Thank you for your help. Regards, Julian

I am considering to upgrade to HOME license. Does the HOME license provides more widgets (including a text message widget), in addition to the 4 basic widgets in the FREE version?
Hi,
I don't know why really. Why is there seems a difference between daily average that calculated with .csv file that has exported directly from the channel.
and calculation with the ThingSpeak Daily Average API, there is a lot of difference at the moment.
Why does this happens, and how should I fix this issue?
Attached image file is daily average that has been retrived through the API,
And attached excel file is raw data from the channel.
Thank you.

We are happy to announce the addition of a new code analyzing feature to the AI Chat Playground. This new feature allows you to identify issues with your code making it easier to troubleshoot.
How does it work?
Just click the ANALYZE button in the toolbar of the code editor. Your code is sent to MATLAB running on a server which returns any warnings or errors, each of which are associated to a line of code on the right side of the editor window. Hover over each line marker to view the message.
Give it a try and share your feedback here. We will be adding this new capability to other community areas in the future so your feedback is appreciated.
Thank you,
David
My Licensed avvount has expired. When I go to my expired license page, I select "Revert To Free Account", I get the following message:
Only administrators of this license are allowed to renew units on this ThingSpeak license. If you want to continue to collect data in your ThingSpeak channels, contact your license administrator.
Aren't I the license administrator? or do I need to contact someone at Thingspeak/MathWorks?

We are thrilled to announce the redesign of the Discussions leaf page, with a new user-focused right-hand column!
Why Are We Doing This?
- Address Readers’ Needs:
Previously, the right-hand column displayed related content, but feedback from our community indicated that this wasn't meeting your needs. Many of you expressed a desire to read more posts from the same author but found it challenging to locate them.
With the new design, readers can easily learn more about the author, explore their other posts, and follow them to receive notifications on new content.
- Enhance Authors’ Experience:
Since the launch of the Discussions area earlier this year, we've seen an influx of community members sharing insightful technical articles, use cases, and ideas. The new design aims to help you grow your followers and organize your content more effectively by editing tags. We highly encourage you to use the Discussions area as your community blogging platform.
We hope you enjoy the new design of the right-hand column. Please feel free to share your thoughts and experiences by leaving a comment below.
I left the code unchanged, modifying only secrets.h.
I am using an ESP32-WROOM -32U
Connection to network succeeds, but ThingSpeak.writeFields fails every time, with HTTP error code 400.
The sketch I am really trying to use is loosely based on this example, accesses Time and Weather info with no problems, but ThingSpeak.writeFields fails with HTTP error code 301.
This is my first attempt to use ThingSpeak.
Is this example sketch still valid, or must I look elsewhere? Suggestions please.
Hi everyone,
I'm working on a school project where I need to send sensor data from my Arduino to a Power BI REST API using ThingsHTTP. I've been trying to get this to work, but I'm running into errors like this:
{"error":{"code":"InvalidRequest","message":"Error parsing request for dataset sobe_wowvirtualserver|a7b68fb5-533b-471f-a5da-3bdd6746ee16: Conversion error on column '<pi>pH</pi>': <pi>Input string was not in a correct format.</pi>"}}
I'm a beginner with this, and I'm not sure what I'm doing wrong. What steps should I take to resolve this issue? Also, does anyone know the correct format for an HTTP request body when sending dynamic sensor data?
This is the body format I'm trying to send to Power BI:
[
{
"pH": 98.6,
"TDS": 98.6,
"turbidity": 98.6,
"temperature": 98.6
}
]
Any advice on how to construct the HTTP body with values that change over time would be greatly appreciated! Thanks in advance!"

The AI Chat Playground at MATLAB Central has two new upgrades: OpenAI GPT-4o mini and MATLAB R2024b!
GPT-4o mini is a new language model from OpenAI and brings general knowledge up to October 2023. GPT-4o mini surpasses GPT-3.5 Turbo and other small models on academic benchmarks across both textual intelligence and reasoning. Our goal is to keep improving the output of the AI Chat Playground. This upgrade is available now: https://www.mathworks.com/matlabcentral/playground/
One more thing... we also updated the system to the latest release of MATLAB. This is R2024b and comes with hundreds of updates and new plot types to explore.Check out Mike Croucher's blog post about the latest version of MATLAB: https://blogs.mathworks.com/matlab/2024/09/13/the-latest-version-of-matlab-r2024b-has-just-been-released/
We are looking forward to your feedback on the updates to the AI Chat Playground. Let us know what you think and how you use this community app.
