Hello
I am trying to run the example code for "Calculate and display average humidity" using my channel data. I filled in the blanks:
  1. readChannelID
  2. humidityFieldID
  3. NumMinutes=720
The program returns display(avgHumidity,'Average Humidity') with "NAN" instead of the correct average. I have a free ThingSpeak account but have been following temperature & humidity every hour for the last 9 months. I would also like to store this average value on the same channel on a new field. Can anyone help me?
Thank You

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.
