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
