Smart home ZigBee-to-Wi‑Fi bridge Sonoff SONOFF-ZB-PRO — connects up to 128 ZigBee devices

Sonoff SONOFF-ZB-PRO is a ZigBee-to-Wi‑Fi bridge that links Zigbee devices to your home Wi‑Fi network and centralizes control. The updated Zigbee Bridge Pro supports up to 128 sub-devices, allows setup of local alarm modes with arm/disarm, and runs local smart scenes and schedules even when Wi‑Fi is disconnected. Plug-in Zigbee devices can act as routers to extend network range. A built-in high-precision RTC preserves time settings through short power outages so scheduled tasks resume after power restoration. Note: local scenes apply to Zigbee devices only.

Advantages

The bridge expands device capacity from 32 to 128 devices while supporting both Zigbee and Wi‑Fi protocols for broader compatibility. It provides local scene execution and timing that continue without cloud or Wi‑Fi, and supports three customizable security modes (home, away, sleep) for simple arming and disarming. Plug-in Zigbee routers improve network range and reliability, and the built-in RTC maintains accurate schedules through brief power interruptions.

Suitable for

• Connecting and managing large Zigbee networks of sensors, switches and lights
• Homes that require local automation and alarm modes without full reliance on cloud services
• Expanding Zigbee mesh coverage using plug-in devices as routers
• Integrating Zigbee devices with Wi‑Fi based smart home apps and platforms

Key specifications

• Model: SONOFF-ZB-PRO
• Function: ZigBee-to-Wi‑Fi bridge
• Max Zigbee sub-devices: up to 128
• Protocols: Zigbee and Wi‑Fi (dual-protocol support)
• Local scene execution: supported (Zigbee devices only)
• RTC: built-in high-precision local real-time clock

How to use

Plug the Sonoff Zigbee Bridge Pro into power and follow the manufacturer app instructions to pair it with your Wi‑Fi network and add Zigbee devices. Configure up to 128 sub-devices from the app, set local scenes and schedules, and create security modes by assigning arming devices for home, away and sleep. Place plug-in Zigbee devices within range to act as routers and extend mesh coverage. Local scenes and schedules will continue to run when Wi‑Fi is unavailable; time settings are preserved by the built-in RTC.

Usage recommendations

For reliable mesh coverage, distribute plug-in Zigbee routers evenly through the premises and keep the bridge within stable Wi‑Fi signal range. Use local scene rules for critical automations that must run without internet access and periodically back up configuration in the controlling app.
