Sonoff Zigbee Bridge PRO (ZBBridge-P), Sonoff's 2022 new product, is a bridge or gateway between Zigbee protocol smart devices (relays and sensors) and the WiFi-based other Sonoff devices, connected through Sonoff's eWeLink Cloud. It also allows you to create smart scenes to make Wi-Fi and ZigBee smart devices communicate to access a smarter home and control them all using the eWeLink APP. It maximizes efficiency for up to 128 connected sub-devices which are Zigbee-based switches, plugs and security sensors.

Pro version can continue to operate its local automations between Zigbee devices even if its internet connection is lost, while previous Zigbee Bridge version's Scenes required internet connection to run scene based automations. (Note: automations between WiFi and Zigbee devices still need internet connection.) 

Zigbee Bridge gateway supports Zigbee 3.0 protocol, and uses the same eWeLink app and eWeLink cloud as other WiFi and RF-based Sonoff and SmartWise devices, therefore it's a practical device to connect Zigbee sensors with other WiFi smart relays and switches into one smart home or smart office system.

As of 20 October, bridge firmware v1.2.0, it is only compatible with Sonoff's Zigbee smart sensors, relays and plugs, and Gledopto Zigbee relays, many SmartWise Zigbee devices are not compatible yet. 

It support the mesh network topology, and the Zigbee range can be extended by plug-in other Zigbee 3.0 (230V AC powered) devices.

One-tap pairing all sub-devices, faster than Wi-Fi pairing. It supports to add a camera on the Bridge or sub-devices, convenient to view your home on any one of them. Can also command Alexa or Google Home to voice control your home.

ZB Bridge-P can connect 26 sub-devices directly (e.g. 10 end devices + 16 routers, or 26 routers). If you want to connect as much as max. 128 sub-devices, devices with Zigbee router feature are required in the Zigbee network, and one router-device can expand to connect 20-32 sub-devices.?
