Shelly 2PM Gen3
Shelly 2PM Gen3 is a Wi-Fi operated dual-channel smart relay with integrated power monitoring and cover control, designed for controlling appliances and motorised covers such as roller shutters, blinds, awnings, and curtains. Its compact design allows retrofit installation behind wall switches or inside standard wall boxes, even where space is limited.
Built on an improved Gen3 processor with increased memory, the device delivers fast local response and reliable automation. It works without a hub, supports local Wi-Fi control and cloud access, and includes roller shutter and Venetian blinds modes with position and tilt control. Power monitoring is available for AC loads only. Motors must be equipped with electronic or mechanical limit switches for cover operation.
