If you have not gotten an answer, let me try that. When you access the devices section in the app, there is a slide switch for standard or custom sorting the circuits in the listing with power you will see. The standard setting constantly sorts and re-arranges the sequence starting with the circuit having the greatest load sensed at the time as first. From there they go down in the same manner.
In custom, if you set that, you can touch and hold down a single circuit at a time and slide it into the desired position on the list then lift your finger. Sorting by power measured is not done on custom. I did not pick that up myself from the install instructions but discovered it in testing.
