Does the SONOFF ZBDongle-E work with HomeKit, Alexa, and Google Home?
The ZBDongle-E is a USB Zigbee 3.0 coordinator, so it is the hub that plugs into a Home Assistant ZHA or Zigbee2MQTT host. It is built on a Silicon Labs EFR32MG21. It suits Home Assistant users through an integration (Zigbee).
Home Assistant (ZHA), Zigbee2MQTT, openHAB[2][3][5] (SONOFF names Home Assistant, openHAB and Zigbee2MQTT. Home Assistant ZHA treats it as tested but not official hardware, and Zigbee2MQTT supports the V2 model.)
Zigbee coordinator software such as ZHA or Zigbee2MQTT[3][6][7]
Yes[3] (Use as a Zigbee gateway in open-source platforms to control Zigbee devices locally.)
Coordinator firmware cannot be added to another gateway (one coordinator per Zigbee network), One application per dongle: ZHA or Zigbee2MQTT, not both at once[3]
How the device gets into the platform on this route. The headline is the best route: local before cloud, direct before bridged, core before community. The methodology page lists every level.
Yes[3][6][7] (Zigbee2MQTT's adapter list includes the V2 model. Home Assistant ZHA lists it as tested but not official, with firmware updates done through the maker's tools.)
