The Shelly Plus 1PM and 2PM are both smart relay switches designed for home automation, but they differ primarily in channel capability. The Shelly Plus 1PM is a single-channel device, allowing control and power monitoring of one circuit, while the Shelly Plus 2PM is a dual-channel device, enabling control and power monitoring for two separate circuits. Additionally, both devices provide features like overload protection, but the dual-channel design of the 2PM offers more flexibility for managing multiple devices or circuits independently.
