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.

Why it stands out
reads your existing electricity meter via its LED pulse output with no electrician needed
provides whole-home energy monitoring through Home Assistant's energy dashboard
completely local Zigbee operation with no cloud or subscription fees
Reasons to hesitate
only works with meters that have a blinking LED pulse output
requires careful calibration of the pulse rate to match your meter
Zigbee coordinator required and sensor must be within Zigbee range of your meter
Best for
Home Assistant users who want whole-home energy monitoring without modifying their electrical panel
EU households with compatible LED-pulse electricity meters
Avoid if
your electricity meter does not have an LED pulse output
you want per-circuit or per-device energy breakdown. This only tracks total consumption
Privacy and local-control notes
Fully local Zigbee device. No cloud or internet needed. Energy data stays entirely on your network.
Home Assistant support: supported · integration path: ZHA / Zigbee2MQTT.
Buying reality check
Price notes: Mid-range pricing for a non-invasive energy monitor. Much cheaper than installing CT clamp systems or professional metering.
Verified price reads: lowest seen $49, latest $49 on Sep 7, 2026.
