Short Description
The Shelly 1PM Gen3 is a compact smart switch with built-in power measurement, enabling remote control of electrical appliances via smartphone, tablet, PC, or home automation systems. It operates standalone within a local Wi-Fi network or integrates with cloud-based home automation services. Compared to its predecessor, it features an upgraded processor and increased memory for improved performance.
The device supports remote access, control, and monitoring from any location with internet connectivity, provided it remains connected to a Wi-Fi router and the internet.
Designed for retrofitting into standard electrical wall boxes, behind power sockets, light switches, or other space-constrained areas, the Shelly 1PM Gen3 offers versatile installation options.
It includes an embedded web interface for configuration, real-time monitoring, and device management.
