SONOFF ZBBridge-U Ethernet Zigbee Bridge Connects Zigbee Devices to Wi-Fi Network

The SONOFF ZBBridge-U is a next-generation Zigbee 3.0 Ethernet bridge designed for high-capacity, stable, and secure smart home automation. Acting as a centralized wired gateway, it connects Zigbee devices to both Wi-Fi and Ethernet networks, significantly improving reliability and response time compared to wireless-only hubs.

With built-in Matter bridge functionality, ZBBridge-U enables Zigbee devices to be exposed to Matter ecosystems, allowing seamless interoperability with Apple Home, Google Home, Alexa, and other Matter-enabled platforms. This ensures long-term compatibility and simplifies multi-platform smart home control.

Powered by the robust EFR32MG21 Zigbee chipset, the gateway delivers fast processing and stable communication, even when managing a large number of connected devices. It supports up to 256 Zigbee sub-devices, making it ideal for large homes, villas, offices, and professional smart-home installations.

Turbo Mode extends Zigbee signal coverage up to approximately 200 meters in open environments, strengthening the Zigbee mesh network and improving connectivity across multiple rooms or floors. The RJ45 Ethernet interface provides low-latency wired networking, ensuring uninterrupted performance for automation-critical systems.

ZBBridge-U is easily managed through the eWeLink app, where users can pair devices, create smart scenes, schedules, group controls, and automation rules. It also supports local control and security features, functioning as a local automation and alarm hub that can trigger actions via NFC, wireless buttons, or predefined scenes—even without internet access.

The bridge is compatible with SONOFF Zigbee devices and a wide range of third-party Zigbee 3.0 products. Advanced users can integrate it with platforms such as Home Assistant for extended automation, monitoring, and customization.
