Sonoff Orb-ZBW1 Zigbee Smart Wall Switch vs Sonoff Orb-ZBW2 Zigbee Double Smart Wall Switch

The Sonoff Orb-ZBW2 Zigbee Double Smart Wall Switch covers two circuits on one plate and adds overheat protection, so it is the more capable switch. The Sonoff Orb-ZBW1 Zigbee Smart Wall Switch is the better buy for a single lighting circuit or a tighter budget, since it shares the same Zigbee 3.0 radio, Detach Relay Mode and integrations.

The circuit count. The Sonoff Orb-ZBW1 Zigbee Smart Wall Switch controls one lighting circuit, while the Sonoff Orb-ZBW2 Zigbee Double Smart Wall Switch controls two independent circuits on one faceplate, each rated at 10A with a combined 16A for resistive loads.

Both need a neutral wire at the switch box, and both need a Zigbee coordinator to be controlled remotely, since neither has Wi-Fi, Bluetooth or Thread. Each still works as an ordinary wall switch without a coordinator.

Not on their own. Both are Zigbee 3.0 and reach Apple Home and Matter through a Sonoff Matter bridge such as the ZBBridge-U or eWeLink CUBE. Alexa, Google Home, SmartThings and Home Assistant work through the usual gateway path.

Anyone replacing a single light switch in a home that already runs a Zigbee coordinator and has a neutral wire at the box, especially when keeping a normal physical button in place matters.

Homes that need two lighting circuits on one plate, and buyers who want the extra overheat protection and the higher combined load rating in a Zigbee-first setup.
