How the device gets into Home Assistant

Known problems and fixes

Requests for ZHA support

support requested The TS110E switch cannot change its physical switch type (Toggle/Momentary) in ZHA, restricting customization options. since January 3, 2026 · zha-device-handlers #4618
support requested The Tuya 2-gang dimmer (TS110e) is not supported in ZHA, so Home Assistant cannot adjust its brightness. Adding support would allow users to control the dimmer through Home Assistant. since October 5, 2025 · zha-device-handlers #4366

Changes proposed for ZHA

pull request A pull request proposes adding support for the Tuya TS110E 2 gang dimmer, which would allow Home Assistant to adjust its brightness settings. since June 9, 2026 · zha-device-handlers #5077

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.

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.
