Shelly PM Mini Gen3 is a compact Wi-Fi power meter for measuring the electrical consumption of a circuit or appliance without switching the load. It provides real-time power data while leaving the connected circuit continuously powered, making it useful where monitoring is required but remote on/off control is not.

The module measures up to 16 A at 240 V AC and is designed for small wall boxes and other constrained spaces. It supports Wi-Fi, Bluetooth-assisted setup and gateway operation, an embedded web interface, scripting, webhooks, MQTT and local or cloud monitoring.
