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 MOES A5 device is not supported in ZHA, so it cannot interact with Home Assistant. Support would enable its functionality within the system. since November 30, 2025 · zha-device-handlers #4538
  • support requested A circuit breaker with power monitoring is not supported, preventing users from tracking energy usage or receiving alerts. Adding support would enable monitoring and threshold-based notifications. since October 16, 2023 · zha-device-handlers #2652

Changes proposed for ZHA

  • pull request A quirk is proposed to support the Tuya TS011F DIN-rail circuit breaker, allowing users to access and configure its protection settings through Home Assistant. since October 31, 2026 · zha-device-handlers #5645
  • pull request Tuya circuit breakers lack threshold controls in Home Assistant. The proposed change would add settings to monitor and trigger alerts based on electrical usage limits. since August 15, 2025 · zha-device-handlers #4267
