Sonoff Zigbee Bridge Pro Gen2 – eWeLink cloud hub, Wi-Fi, Zigbee gateway, Matter bridge (ZBBridge-PR2)

The SONOFF Zigbee Bridge Pro Gen2 ZBBridge-PR2 is a 2.4 GHz Wi-Fi and Zigbee 3.0 gateway with built-in Matter Bridge functionality. It can be used to connect SONOFF Zigbee sensors, switches, smart plugs, thermostats and other compatible Zigbee devices to the eWeLink system. It can manage up to 64 Zigbee sub-devices directly, while the network can be expanded to a total of up to 128 devices with Zigbee routers.

The most important improvement of the Gen2 version compared with the previous ZBBridge-P model is Matter Bridge support. This allows paired Zigbee devices to be exposed to Apple Home, Google Home, Amazon Alexa, Samsung SmartThings and Home Assistant Matter systems. The ZBBridge-PR2 is not a Matter Controller or Matter Hub: it only makes its connected Zigbee sub-devices available on Matter platforms.

The gateway can also handle local automations and security functions. With compatible Zigbee sensors, local scenes can run without an internet connection, while the built-in buzzer can be used for alarms. The Gen2 version uses a new ESP32-S3 + ESP32-H2 hardware platform and USB-C power input.

About SONOFF

SONOFF manufactures smart home devices, relay modules, energy meters, wall switches, Zigbee sensors, control panels, gateways and various electrical installation accessories. Its product range includes devices using Wi-Fi, Zigbee, Matter and LAN communication.

SONOFF devices are primarily based on the eWeLink platform, but many products can also be integrated with Home Assistant, Zigbee2MQTT, ZHA, SmartThings, Alexa, Google Home and other smart home systems.

Key product features

• Matter Bridge: Paired Zigbee devices can be exposed to compatible Matter platforms.
• Zigbee 3.0 gateway: SONOFF Zigbee devices can be used with full functionality in the eWeLink system.
• 64 direct Zigbee devices: Up to 64 sub-devices can be connected directly to the gateway without using routers.

Smart home protocols and platform compatibility

• Zigbee 3.0: IEEE 802.15.4-based Zigbee gateway.
• Wi-Fi: 2.4 GHz IEEE 802.11 b/g/n connection.
• eWeLink: Zigbee device management, automations, security functions and remote access.
• Matter Bridge: Used to expose Zigbee sub-devices to Matter platforms.
• Apple Home: Supported through Matter Bridge.
• Google Home: Supported.
• Amazon Alexa: Supported.
• Samsung SmartThings: Supported through Matter Bridge.
• Home Assistant: Can be integrated through Matter Bridge.

Smart features

• Zigbee device management: Compatible sensors, relays, switches, smart plugs, thermostats and other Zigbee devices can be paired.
• Local scenes: Automations between Zigbee devices can operate without an internet connection.
• Wi-Fi and Zigbee automations: In the eWeLink system, Zigbee and compatible Wi-Fi devices can be used together in shared scenes.
• Security alerts: Events from compatible motion, door/window and other security sensors can trigger alarms.
• Built-in audible alert: The gateway can sound a local alarm.
• Push notifications: The eWeLink app can send notifications for security and automation events.
• Voice control: Supported Zigbee sub-devices can also be controlled using Alexa and Google Home.
• Matter synchronisation: Compatible Zigbee devices can be exposed to Matter platforms; available functions depend on the device type and the Matter platform used.

Comparison with the previous ZBBridge-P model

• Matter Bridge: The ZBBridge-PR2 supports Matter Bridge functionality, while the ZBBridge-P does not support Matter.
• Platform compatibility: Gen2 Zigbee sub-devices can be exposed through Matter to Apple Home, Google Home, Amazon Alexa, Samsung SmartThings and Home Assistant. The ZBBridge-P was primarily designed for the eWeLink system.
• Direct Zigbee capacity: The ZBBridge-PR2 can manage up to 64 sub-devices directly. The direct capacity of the previous ZBBridge-P was significantly lower and depended on the mix of device types.
• Total Zigbee capacity: Both models support Zigbee networks with up to 128 sub-devices when router devices are used.
• Processor and Zigbee radio: The ZBBridge-PR2 uses an ESP32-S3 + ESP32-H2 hardware platform, while the ZBBridge-P is based on ESP32 + CC2652P.
• Power connector: Gen2 uses USB-C, while the previous version used Micro USB.
• Local automation: Both models support locally executed Zigbee automations.
• Security hub: Both models can be used with compatible Zigbee security sensors and local audible alarms.
• Wi-Fi: Both models use 2.4 GHz Wi-Fi.
• Dimensions: Both models measure 62 × 62 × 20 mm.
