Shelly 1 Gen3 vs Sonoff ZBMINIR2 Extreme Zigbee Smart Switch

Despite having fewer standout areas, the Sonoff ZBMINIR2 Extreme Zigbee Smart Switch is the winner of this smart relay comparison against the Shelly 1 Gen3, helped by typically being the more affordable pick, retaining its last switch state through a power cut via power-off memory, and pulling double duty as a Zigbee router for the rest of your mesh. The Shelly 1 Gen3 pushes back with a much broader integrations list, adding Apple HomeKit through Matter on top of Google Home, Alexa, SmartThings and Home Assistant, plus dry-contact wiring the Sonoff does not offer, and it connects straight to Wi-Fi with no hub, where the Sonoff needs a Zigbee hub. Both switch a single circuit with no energy monitoring, and both need a neutral wire on mains power. Choose the Shelly 1 Gen3 if you have no Zigbee hub or you want Matter and HomeKit support with dry-contact flexibility for a garage door; choose the Sonoff ZBMINIR2 Extreme Zigbee Smart Switch if you already run a Zigbee mesh and want a cheap router node that remembers its state.
