Shelly EM Mini Gen4 is a small form factor energy meter. Enhanced with all the gen3 firmware flexibility and also some of EM type Shelly devices, it provides professional integrators with additional options for end-customer solutions. It can work standalone in a local Wi-Fi network, or it can also be operated through cloud home automation services through MQTT, HTTP, and WebSocket. All inbound connections support TLS. The device is an improved version of Shelly PM Mini Gen3 with a more advanced processor and Zigbee connectivity.

Shelly EM Mini Gen4 can be accessed, set up, and monitored remotely by the User, as well as the Device can access and communicate with an automation system, as long as they are in the same network infrastructure.

The Device has an embedded Web Interface which can be used to monitor and control the device, as well as adjust its settings.
The device has multi-protocol wireless MCU which provide Zigbee and Bluetooth connectivity ensuring a secure connection.

This device is compatible with Matter.
