How the device gets into Home Assistant

Requests for ZHA support

support requested The Nous D4Z 3-phase power meter is not supported in ZHA, so its energy measurements cannot be read or displayed in Home Assistant. Adding support would allow monitoring of electricity usage for three-phase systems. since October 15, 2026 · zha-device-handlers #5461

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.
