How to use "My electric" App with 3 phases

I try to use this app for my 3-phase household. But I have no idea how to setup the feeds correctly that they may be used as a 3-phase energy monitor. I checked all manuals and info here already.

Can you give me a hint, please?

Hi, I recently did just this.


Using the input processors, use 1 of the 3 inputs to add all three phases together. PHPFINA has to be used for the Apps to work.
