Short Description
The Shelly 1PM Mini Gen3 is a compact smart switch with built-in power measurement, enabling remote control of electric appliances via mobile phone, tablet, PC, or home automation systems. It operates both locally within a Wi-Fi network and through cloud-based home automation services. This device is an improved version of the Shelly Plus 1PM Mini, featuring a more advanced processor and increased memory.
It supports remote access from anywhere with internet connectivity, provided the device is connected to a Wi-Fi router. Designed for retrofitting into standard electrical wall boxes, behind power sockets, light switches, or other space-constrained locations.
The device includes an embedded web interface for monitoring, controlling, and adjusting settings.
