Problems with homebrew and three-phase

[overeasy]

@Nico

I am installing my first IOTAWATT in a 3-fase system. With direct voltage reference on each fase.

I searched back to come up to speed on what you are doing and found this:

Adaptors for 3-Phase Direct Reference

Me and a friend of mine made new pcb designs to accommodate for 3 phase direct measurement all on board (you only have to populate different parts on the PCB). Still in the testing phase but so far everything seems to work. We also changed connectors (cost far less) If anyone is interested i can mail the schematics and PCB design. I even have some prints available (at a price) because my Chinese friends only produce them 10 at a time. I can post some pictures if wanted

I’m not clear on what we are talking about here. Did you make a voltage adapter or an actual ESP8266 device with ADCs etc? Do you have a picture of the unit that is experiencing these problems?
