I'm quite disappointed after I received my Pro4 PM. I thought it was able to control 4 separate phases thus making it possible for me to feed it with 4 separate wires. But all the phases (L) are just shorted.
Not very "pro".
I have a water heater using three-phase power (3x240V - 11A each) - and I'm not happy using several Shelly 2.5PM....
Hmm.. Ok - just sharing my frustration...
Maybe there will be a next generation "Shelly Pro 4PM Plus deLuxe"
