Hello,
Would it be possible to replace a shelly em ( power metering of an air conditioning) with a shelly pro 1 PM ?.
Situation : the air condition (daiking multisplit unit outside) is connected directly to a circuit breaker in the central breaker box, no switch in between circuit breaker and air conditioning.
I have a shelly em installed to measure the consumtion (works fine), but i was wondering if I could replace it with a pro 1 pm. I tried to figure it out myself, but I don't quite understand the general wiring sheme of the pro 1 pm.
If this would be possible, what would be a wiring scheme (knowing there are only 3 wires who leave at the circuit breaker (L/N/ground).
Remark : i wouldn't try to wire the pro 1 PM myself (i would ask an electrician), but i would very much like to understand how it could work !
Thanks.
