Description
The Shelly 2PM Gen3 is a smart 2-channel relay designed for the remote control of electrical appliances, lighting, roller shutter motors and other loads, and also features an energy consumption measurement function for each channel.
The device allows independent control of two electrical circuits and can also operate in cover mode, making it ideal for external roller shutters, Venetian blinds, awnings or other motorised systems. In this mode, the Shelly 2PM Gen3 can control both the position and the tilt of the Venetian blind slats.
Thanks to its compact dimensions, it fits easily into standard wall boxes, behind switches or sockets, making it suitable for both residential and commercial projects.
The new generation features an improved processor and expanded memory, delivering better performance, rapid response and advanced integration into smart home ecosystems.
