Shelly EM Mini Gen4

The Shelly EM Mini Gen4 is a compact energy meter, allowing you to monitor the energy consumption of your connected devices up to 16A. It’s equipped with a Shelly chip and multiprotocol connectivity support including Wi-Fi, Zigbee, Bluetooth and Matter.

***This device does not offer any switching capability***. We offer the Shelly 1PM Mini Gen4 for both switching and power monitoring in a single mini device.

The Shelly EM Mini Gen4 tracks the energy consumption of the connected appliance or device, giving you a clearer picture of how much energy each device is using, helping you to reduce waste and optimize your costs. Designed with convenience in mind, these mini devices have all the capabilities of Shelly’s standard smart devices fit into a compact form factor. With an improved processor and 8MB of memory, the devices deliver enhanced efficiency, responsiveness, and seamless operation.

Each Mini Gen4 device is Matter-certified and supports multi-protocol connectivity, allowing greater flexibility within your smart home setup. With support for Wi-Fi, Bluetooth and Zigbee, and also Matter-certified, you can integrate it into a wide range of smart home systems without needing a hub – including Home Assistant!

Note: You may require a neutral wire to use this product. Please research the device and your home wiring (safely, see below) before purchasing.
