Does the SONOFF Orb-ZBW1 work with HomeKit, Alexa, and Google Home?
The Orb-ZBW1 needs a Zigbee 3.0 hub or coordinator.
It is a one-gang wall switch in an 86 mm plate, rated 10 A, and it acts as a Zigbee router. It suits HomeKit users through an integration (a Matter bridge). Alexa, SmartThings and Home Assistant users reach it through an integration (Zigbee).
