Does the SONOFF Bridge Max work with HomeKit, Alexa, and Google Home?
The Bridge Max is itself the hub, over Ethernet or Wi-Fi.
It connects Zigbee, BTHome and eWeLink devices to HomeKit, Alexa, Google Home and other Matter platforms, and syncs Zigbee devices to Home Assistant over MQTT. It suits HomeKit, Google Home and Alexa users through an integration (a Matter bridge). Home Assistant users reach it through an integration (the maker's hub).
