What It Does Well

A Zigbee Hub for the Whole Home

A round white hub with a status light at the front, shown with its ZBBridge-U retail box. It pairs Zigbee switches, sensors, plugs and radiator valves, and adds them to the eWeLink app for control and smart scenes.

Matter Bridge to Apple, Google and Alexa

With a Matter hub (such as a HomePod or Apple TV) on the same network, the bridge passes its Zigbee devices, your eWeLink devices and Home Assistant devices into Apple Home, Google Home, Alexa and other Matter platforms. Devices synced this way stay controllable on your LAN even when the internet is down.

Works with Home Assistant

Set up an MQTT broker and the bridge syncs its Zigbee devices to Home Assistant, so you can manage the same switches, plugs, thermostatic valves and water valves from the eWeLink app and from Home Assistant.

FAQ

Product Questions & Store Policies

Which Zigbee devices can I add?
SONOFF says the ZBBridge-U currently supports Zigbee sub-devices from the SONOFF and eWeLink ecosystems, and publishes a list of supported third-party devices. Check that list before buying another brand's sensor or switch.
Do I need a Matter hub to use it with Apple Home or Google Home?
Yes. Matter bridging needs a Matter hub, such as a HomePod or Apple TV for Apple Home, on the same local network as the bridge and your phone.
Can I connect it by cable instead of Wi-Fi?
Yes. It has an RJ45 Ethernet port (10/100 Mbps) as well as 2.4 GHz Wi-Fi. When pairing over Ethernet, keep your phone's Wi-Fi on the same local network.
How far does Zigbee reach?
SONOFF quotes 100 m at default power and 200 m in Turbo mode in open outdoor space, and about 10 m through walls indoors. Mains-powered Zigbee devices that act as routers extend the network.
Does it work without the internet?
Devices bridged into Matter stay controllable on your local network when the internet is down or unstable, and a local web interface lets you add devices to Matter platforms from a browser.
