Brief description

Shelly 1PM Mini Gen4 is a compact smart switch with power consumption measurement that allows you to control electrical devices via mobile, tablet, computer, or home automation system. The device can be used independently in a local Wi-Fi network or through cloud-based home automation services.

It is an improved version of Shelly 1PM Mini Gen3, featuring a better processor and Zigbee connectivity.

The device can be accessed, controlled, and monitored from anywhere with an internet connection when connected to a Wi-Fi router.

The device can be installed in standard wall boxes, behind outlets or switches, or in other confined spaces.

Shelly 1PM Mini Gen4 has a built-in web interface through which the device can be monitored, controlled, and configured. The device uses a multi-protocol wireless MCU supporting Zigbee and Bluetooth connectivity to ensure secure communication.

The device is compatible with the Matter protocol.
