Hi,
I built a small Home Assistant add-on: Z2M Discovery Translator.
Problem:
Zigbee2MQTT exposes some device-specific entities through MQTT Discovery with English names, e.g. “Smart temperature control”, “Child lock”, “Valve opening degree”. Home Assistant can translate generic device classes, but not these Z2M-specific labels.
Solution:
The add-on acts as a lightweight MQTT Discovery proxy:
Zigbee2MQTT → z2m_discovery → Z2M Discovery Translator → homeassistant → Home Assistant
Known names are translated using JSON translation files. Unknown names are forwarded unchanged.
Main use case:
French Home Assistant setups using Zigbee2MQTT, but the project is designed to support other languages through translation files.

Feedback and translation contributions are welcome.
