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.
  • official Tuya Zigbee gateway – paired with a Tuya Zigbee gateway and controlled through the Tuya cloud with the Tuya integration.
  • add-on Zigbee2MQTT – Zigbee2MQTT runs as an add-on and passes the device on to Home Assistant over MQTT. Source
