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
add-on Zigbee2MQTT – Zigbee2MQTT runs as an add-on and passes the device on to Home Assistant over MQTT. Integration · Source

Known problems and fixes

Requests for ZHA support

support requested The HOBEIAN ZG-305Z USB switch is not supported in ZHA, so you cannot control its two USB ports through Home Assistant. Adding support would allow you to manage the switch's functions via automation or manual control. since September 13, 2026 · zha-device-handlers #5329

Changes proposed for ZHA

pull request Both USB outputs of the HOBEIAN ZG-305Z are not exposed as switches. This pull request would allow independent control of both ports in Home Assistant. since September 14, 2026 · zha-device-handlers #5343

ZHA quirks for this device

Quirk proposed, not merged yet Recommended quirk

Proposed to ZHA and waiting for review – the maintainers check it before it becomes part of Home Assistant.

Signature: HOBEIAN / ZG-305Z

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.
