I am new to the ThingSpeak platform and I am trying to display the 1440 average of my data I am sending from an Arduino Uno. I am sending data from 5 different detectors to be plotted into 5 different fields on my ThingSpeak channel. The live data plotted is quite accurate but when I chose to plot the average I get values significantly lower than it should be. I am suspecting it to have something to do with the bunch of Null values I have here for example maybe: https://thingspeak.com/channels/126439/field/4.json

You are correct. The average is using null's and lowering the expected average.

If you have two devices, you might want to update two different ThingSpeak channels.

If that is not possible, then MATLAB can help here. You can use MATLAB Analysis app to read in the field data, ignore the nulls, and then calculate the average. You can even use MATLAB to write the averaged data to a new processed channel and have it calculate the daily average each day by scheduling it with TimeControl.
