Qubino 3-phase smart meter - Homey Energy

I can’t move it, but this is the “official” Qubino thread, also with support from Qubino itself:

Regarding your question:
In the advanced device settings (category energy) of the 5 individual smart meter devices (main device, all 3 phases and phases 1 - 3) you can select whether they should be included in the total consumption or not.
