I would like to have a widget to control a pump connected to Thingspeak via Talkback. I have also established a connection with thingspeak where I publish my sensor data to the channel and can visualize the data through the various widgets. But I cant find a widget or method to control the pump from a graphical perspective on the channel (like a switch or button interface where clicking them would turn the pump on or off). Thingsboard seems to have the feature, not sure of thingspeak. If anyone knows a way please do comment out. Have a great day!

Testing APPS - TalkBack

Hello,

Opening TalkBack in Firefox and trying to Add a new command, the green button doing nothing. If I refresh the page, it works fine. First time have a issue - not work... Edge is working from the first time.

An error occurred while executing the code. I was referring this site : https://in.mathworks.com/help/thingspeak/monitor-channel-inactivity-using-multiple-thingSpeak-apps.html

While executing the code

Error using matlab.internal.webservices.HTTPConnector/copyContentToByteArray (line 373) The server returned the status 400 with message "Bad Request" in response to the request to URL https://api.thingspeak.com/apps/thinghttp/send_request?3DOHBYUXDXD4OVIV=WA327EPXB1DWM0FA.
