I would like to measure the electricity consumptions of 3 large 3-phase AC units I have. What are my options? Shelly 3em on each I know.
Would the future Shelly 4 Pro Plus work as well? I can't find any information on using 3 phases in one Shelly 4. Would I have to use 3 Shelly 4, one for each phase?
Also, on a 3 phase device, is it too much of a leap to assume each phase uses about the same amount of power, and just multiplying the power consumption on 1 phase by 3. In that case 1 Shelly 3em would work.
