How the device gets into Home Assistant

official ZHA – with a Zigbee coordinator and the ZHA integration; for all its functions it needs a custom quirk, see above. Integration
official Aqara hub – paired with an Aqara hub that works as a Matter bridge (such as the M3 or M2), which shares supported devices with Home Assistant. Integration
add-on Zigbee2MQTT – Zigbee2MQTT runs as an add-on and passes the device on to Home Assistant over MQTT. Integration · Source

The quirk is not part of ZHA yet. You can use it as a custom quirk until it is:

Tell ZHA where custom quirks are kept – in configuration.yaml:
```
zha:
  custom_quirks_path: /config/custom_zha_quirks/
```
Create that folder and save the quirk as a .py file in it.
Restart Home Assistant. If the device was paired before, reconfigure it or remove and pair it again so the quirk is applied.
Check it worked: the device page shows the quirk under Zigbee info.

A custom quirk has not been reviewed by the ZHA maintainers. Delete the file once the quirk is part of a Home Assistant release – otherwise the old copy takes precedence.
