PM Mini Gen3

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.

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.

Recipes using this device

Energy · v1.0.0

High Energy Usage Alert

Installs a Home Assistant automation that watches your whole-home power draw and warns you when it stays high for longer than it should, so a heater or a forgotten appliance does not run all day unnoticed. Add speakers to hear it, add a smart plug to shed the load.

Solar Surplus EV Charging

Installs a Home Assistant automation that starts your EV charger when your solar array is producing a surplus and stops it when production drops, so the car pulls from the roof rather than the grid. Add a grid meter and a home battery and it holds back until they are happy too.
