Description

The Shelly Mini 1PM Gen4 is a compact smart relay with built in power metering, designed to control a wide range of electrical appliances up to a maximum load of 8A. Despite its small size, it delivers full functionality and can be controlled individually via the free Shelly mobile app, through more than 200 integrations including Amazon Alexa and Home Assistant, or as part of a synchronised schedule or scene alongside other Shelly devices.

As the latest addition to Shelly’s Mini range, the Mini 1PM Gen4 features an upgraded chipset and increased RAM compared to the Gen3 model, allowing for faster response times and more advanced scripting. Like all Gen4 devices, it supports Matter and Zigbee straight out of the box, while retaining Bluetooth and WiFi compatibility from previous generations. These connections can operate at the same time, enabling the device to communicate over WiFi within a Shelly ecosystem while also integrating seamlessly with existing Matter or Zigbee systems.

Beyond smart switching, the Shelly Mini 1PM Gen4 offers precise energy monitoring, measuring the power consumption of connected devices with an accuracy of up to 1 percent. Energy data is stored both locally on the device and securely in the cloud, providing a clear, high level overview of energy usage across your smart home setup.
