Quick verdict
A clever way to get whole-home energy data into Home Assistant without touching your electrical panel. It attaches to your electricity meter and reads the LED pulse to track consumption. Simple, non-invasive, and fully local over Zigbee. Setup requires matching the pulse rate to your meter, but once calibrated it feeds directly into Home Assistant's energy dashboard. A great option for EU homes with compatible meters.
Standout: Non-invasive whole-home energy monitoring by reading your electricity meter's LED pulse.
