How the device gets into Home Assistant

  • official ZHA – with a Zigbee coordinator and the ZHA integration; the quirk the device needs is part of ZHA.
  • official Aqara hub – paired with an Aqara hub that works as a Matter bridge (such as the M3 or M2), which shares supported devices with Home Assistant.
  • add-on Zigbee2MQTT – Zigbee2MQTT runs as an add-on and passes the device on to Home Assistant over MQTT. Source

Alternatives

The same job from other makers – devices of the same type and radio that work with Home Assistant too.

Sources: Zigbee2MQTT, ZHA quirks, Z-Wave JS, the Matter certification database, Shelly, ESPHome, Tasmota, Tuya Local and the issue trackers on GitHub. Reports are assigned to a device by the identifiers they contain; the sentences come from the integration pages, where a language model writes them from the titles.
