Features

Real-Time Energy Monitoring

The Shelly EM Mini Gen4 measures active power and accumulated energy consumption from the connected circuit, helping users understand how much electricity individual appliances and devices are using.

Up to 16A Measurement Capacity

The meter supports measurement up to 16A at a maximum of 240V AC, with a maximum monitored power of 3840W. This makes it suitable for many household appliances, sockets and individual electrical circuits.

Multiprotocol Connectivity

Wi-Fi, Bluetooth, Zigbee and Matter support provide flexible integration with different smart-home ecosystems. Users can choose the most suitable protocol for their installation while maintaining compatibility with supported third-party automation platforms.

Compact Retrofit Installation

Measuring just 29 x 34 x 16mm, the EM Mini Gen4 is designed to fit into standard wall boxes and other confined installation spaces, including behind compatible wall sockets and switches.

Energy History and Data Export

The device stores at least 10 days of measurement data at one-minute resolution. Recorded values can be exported in CSV format, while JSON export is available through RPC for integration into monitoring and automation systems.

Smart Schedules and Automation

Support for schedules, webhooks, scripting, MQTT and advanced local actions allows the EM Mini Gen4 to participate in broader energy-management workflows and automations.

Range Extender and Bluetooth Gateway

The EM Mini Gen4 can function as a Wi-Fi and Zigbee range extender and as a Bluetooth gateway, helping improve connectivity between compatible Shelly and smart-home devices.

• This device is an energy meter only and does not contain a relay.
• It cannot independently switch the connected appliance or circuit on or off.
• Shelly recommends suitable external circuit protection of up to 16A.
• Installation on mains-voltage circuits should be performed by a qualified electrician.
