Houman and Rameez will talk about how you can model wireless networks (5G, WLAN, Bluetooth, 802.11ax WLAN mesh, etc.) in MATLAB in the upcoming livestream. They will start with the basics such as nodes, links, topology and metrics. Then they will introduce a new free add-on library that lets you model such networks, and show you how to use it.

I wanted to write to my public channel 2278931 with 8 different values to 8 different gauge widgets.
Here is my link.
https://api.thingspeak.com/update.json?api_key=xxxxxxxxxxxxxxxx&field1=1&field2=2&field3=3&field4=4&field5=5&field6=6&field7=7&field8=8
You can change values and in the link to change gauge values. On edit I edited my write key to make it not work for others but it will work with your own key.

Up until a few weeks ago, there was a "channels shared with me" option in Thingspeak. I was able to access the channel created by a different user, only once. The next time me and my groupmate tried to open the channel, there wasn't a "channels shared with me" option anymore. Why is that and how can this be resolved?
MATLAB Onramp is a free online tutorial and it has been very popular with new MATLAB users to learn how to use it, and MathWorks have been adding more and more modules. The lastest one just dropped https://matlabacademy.mathworks.com/details/power-systems-simulation-onramp/orps
It shows you the basics of power system simulation by modeling a simple microgrid. You will learn how to simulate and measure three-phase circuits, and how to evaluate algorithms like droop control and maximum power point tracking.
Is there any problem from thingspeak side, from last month my data is not uploading
Here's a screenshot from 22 years ago. Thanks for building one of the best engineering and science communities together.
Currently, I am trying to setup MATLAB and Simulink to connect with Unity. But I have some questions about the installation of ROS on my computer and ROS Toolbox. I found that there are several ROS installations, so, could you please kindly help and support? Hoping that your support will help a lot to my master's thesis.

Hi! Actually I'm trying to store data from 5 sensors on the ThingSpeak cloud. I was able to do it 2-3 days back, but right now I'm trying to do the same for last 2-3 hours and it's just not happening. There's nothing wrong with the code because it's getting compiled properly. I'm using
ThingSpeak.writeFields(2261556,"xxxxxxxxxxxxxxxx");
I tried printing its value after storing in a temporary variable........The value comes out to be -301. Is there any fix for this? I need it urgently for a project.
I hope to receive some help soon. Thanks!
% Sample data from channels
channel1Data = 2226948; % Your data for channel 1
% Threshold values for each alert level
threshold1 = 100;
threshold2 = 200;
threshold3 = 300;
% Initialize alert level to 0 (no alert)
alertLevel = 0;
% Check thresholds and determine alert level
if channel1Data >= threshold1 && channel1Data <= threshold2
alertLevel = 1; % Yellow Alert
elseif channel1Data >= threshold2 && channel1Data <= threshold3
alertLevel = 2; % Orange Alert
elseif channel1Data >= threshold3
alertLevel = 3; % Red Alert
end
% Define alert message based on alert level
if alertLevel == 1
alertMessage = 'Threshold exceeded for channel 1!';
elseif alertLevel == 2
alertMessage = 'Threshold exceeded for channel 2!';
elseif alertLevel == 3
alertMessage = 'Threshold exceeded for channel 3!';
else
alertMessage = 'No alert for channel 1.';
end
% Call SMS integration function with the alert message
sendMessage('+639319217695', alertMessage);
function sendMessage(number, message)
% Replace with your SMS service API endpoint and API key
apiUrl = 'https://api.semaphore.co/api/v4/messages';
apiKey = '-----';
% Compose the message payload
payload = struct('apikey', apiKey, 'number', number, 'message', message);
try
% Send the SMS using the SMS service API
response = webwrite(apiUrl, payload);
% Process the response as needed
disp('SMS sent successfully');
catch
disp('Error sending SMS');
end

I've just bought a rain gauge with esp 32 but the problem is Its code is already programmed on esphome
Now I need to send the data to one of my channels so I can perform the logic for my sms API

Hi
We are using Raspberry Pi to send some sensor data to Thingspeak. Is it possible to send this data to any other IoT hub service lets say Thingsboard, AWS or Azure IoT hub? Does Thingspeak provide any kind of API which can give us alerts whenever the data is received in Thingspeak server ?
Thanks
I was unable to update fields during this time and was also unable to login to thingspeak.com.
Hi, is the timecontrol in matlab stop running around 1500 UTC+8 230809?
Hi I'm a newbie, the data I'm sending from the weather station I'm trying hasn't reached me for about 1 week.
Or rather, the data is sent regularly from the station to Thingspeak which connects and sends, but looking on the site it seems that they are not received.
The latest data received, in fact, dates back to 7 days ago.
By chance, after sending the 8000 available data, does the service stop?
Hello, an intern working at MathWorks is finishing up his program soon and he would like to interview some MATLAB users. He is looking for people who can give their perspective on the question:
"What makes MATLAB and Simulink special in comparison to other languages?"
Ultimately he plans to condense the answers into 15-second videos or sound bites.
If people are willing to participate but want more time to talk about their experience with MATLAB, he doesn't have time left for in-depth interviews but he can find someone else to take over the project.
Please send me an email via my profle if you are interested.
