Shelly 1PM Mini Gen4

Overview

The Shelly 1PM Mini Gen4 is an ultra-compact smart relay with integrated power monitoring, designed for controlling lights and small electrical appliances where space is limited. With an 8A switching capacity and precise real-time energy monitoring, it is ideal for retrofitting behind wall switches or sockets without altering existing wiring layouts.

As part of the Shelly Gen4 range, the 1PM Mini Gen4 introduces multi-protocol connectivity, allowing you to choose between Wi-Fi, Zigbee, Bluetooth, or Matter, depending on your smart home setup. The upgraded processor delivers faster response times and smoother automation performance, while maintaining the same small form factor that makes the Mini series so popular.

The device operates without a hub when using Wi-Fi or Matter and integrates seamlessly with the Shelly Smart Control app, Home Assistant, Apple Home (via Matter), and other automation platforms. Built-in power metering allows you to track consumption, optimise energy usage, and create automations based on real usage data.
