Overview

Shelly 1PM Mini Gen3 is an ultra-compact Wi-Fi smart relay switch with integrated real-time power metering, designed to remotely control and measure energy usage of lights and small electrical appliances. Its miniature form factor fits inside standard wall boxes or behind wall switches and sockets for discreet smart upgrades.

Built on the Shelly Gen3 platform with a new ESP-based processor and increased flash memory, it offers improved responsiveness and future firmware support. It works without a hub, connects to 2.4 GHz Wi-Fi, and also supports Bluetooth for provisioning and gateway functions. Power metering enables precise analysis of consumption, and open protocol support allows integration with a wide range of automation systems.
