Shelly 1PM Gen4

Paired it straight to my ZigBee hub and it showed up in seconds, no app juggling needed. The power monitoring is what sold me — I can finally see exactly what my space heater pulls on high. Relay clicks are quiet enough that I forget it's behind the switch.

Was worried this would be fussy to set up but it linked right up over Bluetooth, then switched to ZigBee once it was on my network. The power monitoring is scarily accurate — I finally caught which appliance was spiking my bill.

Wired this behind our bathroom light switch and it paired to my ZigBee hub on the first try, no fiddling with the app at all. The power monitoring is the part I actually use — I can see exactly what the exhaust fan draws.
