Question about Thingspeak :
(I'm using free version)
From a few days ago, I can't display more than about 38Hrs, although I set to 5 days (2,3days either).
Although I change TIMESCALE to 10, result is the same.

What is your update rate for that channel? The maximum number of points you can read in a single plot is 8000. Except in limited cases, you can't get more by averaging in the ThingSpeak charts. You can use the charts API to specify a daterange for your chart, or create a custom MATLAB Visualization to show a different collection of points. This example shows one way to read past dates.
