GreenEye Monitor (GEM)
greeneye_monitor
The GreenEye Monitor (GEM) integration for Home Assistant allows you to create sensors for the various data channels of the GEM. Each current transformer (CT) channel, pulse counter, and temperature sensor appears in Home Assistant as a sensor, and can be used in automations.
In Apple Home through HomeKit Bridge
What HomeKit Bridge makes of each kind of entity this integration creates, read from its source code. A device only gets the ones that apply to it.

What people report
GreenEye Monitor works locally; a 2022.2 library update briefly broke value parsing for one user's COM 5.13 firmware, later closed as completed.

| GreenEye Monitor (GEM) | Works Local | Fixed after 2022.2 value parse regression reportSaved copyThe problem After upgrading to 2022.2.6 (and 2022.2.7) the Greeneye Integration stopped reporting values. Tracking the error showed that there is a problem converting the values received with a HEX Conversion exception. This happens on an upgraded instance as well as a new instance of home-assistant. I have tried BIN-32 ABS, BIN32-NET, BIN42-ABS, BIN42-NET in GEM. This was working up to 2021.12.10. --- Logging error --- Traceback (most recent call last): File "/usr/local/lib/python3.9/site-packages/greeneye/monitor.py", line 429, in _consumer await self._listener(message) File … Excerpt saved from GitHub on 2026-10-23. | Issue #66709 · 2022-02 |
