SONOFF Zigbee Bridge Pro
The SONOFF Zigbee Bridge Pro (model ZB Bridge-P) is a Zigbee 3.0 hub that connects SONOFF and eWeLink Zigbee devices to your Wi-Fi network and the eWeLink app. It supports up to 128 Zigbee sub-devices and is powered by 5V DC 1A.




Up to 128 sub-devices: One bridge can manage up to 128 Zigbee sub-devices, compared with 32 on the previous SONOFF Zigbee Bridge. SONOFF notes that the bridge connects directly to 10 end devices (or 26 routers), so Zigbee router devices are needed to reach the full 128.
Security modes: You can set up three security modes, Home, Away and Sleep, and choose which sensors arm each mode. The bridge has a built-in buzzer, so it can work as a local alarm hub, and with a wireless button it can also act as a doorbell.
Local scenes: Smart scenes and Zigbee linkages run locally, so they keep working even if the Wi-Fi or internet connection drops (Wi-Fi is needed during setup). A built-in high-precision RTC keeps the time, so schedules continue after short power outages.
Voice control: Works with Amazon Alexa and Google Assistant, so you can control connected devices by voice through your eWeLink account.
Who it's for / Works with
SONOFF and eWeLink Zigbee sub-devices, such as Zigbee sensors, switches and plugs, managed through the eWeLink app.
Good to know
Wi-Fi works on 2.4 GHz only. Directly connected devices are limited to 10 end devices (or 26 routers); add Zigbee router devices to expand the network towards 128 sub-devices. The bridge is set up through the eWeLink app.
