The Shelly Plus 1PM and 2PM are both smart home devices used for automation and energy monitoring, but they differ primarily in their channel capabilities. The Shelly Plus 1PM is a single-channel relay, meaning it can control one electrical circuit, whereas the Shelly Plus 2PM is a dual-channel relay, allowing it to control two separate circuits independently. Both devices support Wi-Fi connectivity and can monitor power consumption, but the 2PM offers additional versatility for controlling multiple devices or circuits.
