Choose countryShelly PM Mini Gen3 is an energy meter for monitoring connected devices in real time. It helps identify energy-intensive appliances and track the consumption of individual devices.
Local operation and remote monitoring
The meter can operate independently on a local Wi-Fi network or work with cloud-based home automation services. Its built-in web interface provides monitoring and configuration, while remote access lets you check energy use away from home.
- Integration: supports MQTT(s), HTTP, WebSocket, documented HTTP APIs, webhooks over HTTP and HTTPS, and UDP. All incoming connections support TLS.
- BLE gateway: bridges Shelly BLU devices and the wider Shelly ecosystem.
- Wi-Fi extension: can extend Wi-Fi coverage for IoT devices.
- Scripting: supports scripts for automation.
Power and installation
Designed for wall-box mounting, the meter uses a 110–240 V AC supply. Maximum measurement limits are 240 V, 16 A and 3840 W. External protection must have a B or C tripping characteristic, a maximum rated current of 16 A, a minimum breaking capacity of 6 kA and energy limitation class 3.
