Shelly 2PM Gen4 – 2-Channel Smart Switch with Power Monitoring
The Shelly 2PM Gen4 is a compact 2-channel smart switch with power measurement, designed for controlling and monitoring two electrical circuits or motorised covers from one small module. It can be installed behind switches, power sockets, or inside standard wall boxes wher
After 2 weeks of using Shelly 2PM Gen4, my feedback:
Pros:
Power Metering: Tracks exact energy use for two separate circuits in real time.
Small Size: Fits easily behind standard wall switches in tight electrical boxes.
Local Control: Works smoothly with local automation systems via MQTT and HTTP without needing the cloud.
Safety Features: Includes built-in overheating and overload protection.
Integration to HA: Home Assistant automatically detected the relays and installed Shelly integration.
Flexibility: I can choose any protocol from ZigBee, Bluetooth and Matter. I chose Matter.
