Shelly PM Mini Gen3 is an ultra-compact Wi-Fi power meter that clips behind a fixture or socket to measure a circuit's voltage, current, and energy without switching the load.

Roles it can fill
Measurement only, with no relay, so it monitors a circuit you do not want to switch. Small enough for crowded back boxes. The native Shelly integration gives local control with no cloud required, plus Bluetooth and MQTT.
