ZBBridge-U

Product Overview

Introduction

Product Name	SONOFF Zigbee Bridge Ultra
Product Model	ZBBridge-U

Zigbee Bridge Ultra is a Zigbee gateway that enables wired or wireless connections. It supports smart security, voice control, and scene linkage with other devices. Additionally, it acts as a Matter bridge, allowing Zigbee devices to be converted into Matter devices, making it easy to integrate with different smart home products for home automation.

Highlights

Seamless Matter Bridge Integration

Break the boundaries of smart home ecosystems. Seamlessly bridge SONOFF and eWeLink Zigbee sub-devices into the Matter ecosystem when paired with a Matter hub on the same LAN.

High-Performance Hardware for Fast Automation

Equipped with a Zigbee 3.0-compatible EFR32MG21 chip, dual-core 1.5GHz CPU, 1GB DDR4 RAM, and 8GB eMMC storage to ensure ultra-stable and responsive performance.

Massive Zigbee Device Capacity

Supports pairing with up to 256 Zigbee sub-devices — ideal for growing smart home setups with sensors, switches, and smart plugs.

Reliable Wired & Wireless Options
Connect via Wi-Fi or RJ45 Ethernet to ensure smooth and responsive device communication.

As a Smart Security Hub

Set up local security scenes triggered via NFC tags, wireless buttons, or app control. Get instant push notifications and audible alerts when intrusion is detected.

Applications

Bridge Between Zigbee and Matter Ecosystems

Seamlessly integrate SONOFF Zigbee devices into Matter-supported platforms (like Apple Home, Google Home, Amazon Alexa) through the Matter bridge function—breaking ecosystem barriers and simplifying cross-brand automation.

Central Hub for Smart Security Systems

Combine with Zigbee door sensors, motion sensors, and cameras to create a responsive smart security system. Use scene automation like “When motion is detected, turn on hallway light.”

Multi-Device Scene Linkage

Enable complex scenes involving Zigbee smart plugs, switches, sensors, and lighting. Example: “If the front door opens, turn on the porch light and disable the indoor motion sensor for 30 seconds.”

Smart Home Ecosystem Expansion

Extend your Zigbee mesh network and integrate more sub-devices like thermostats, curtain switches, or temperature sensors to cover your entire home automation needs.

Ideal for DIYers & Multi-Platform Homes

For tech-savvy users building smart homes with mixed-brand devices, Zigbee Bridge Ultra provides a future-proofed, interoperable control center that supports both traditional Zigbee and next-gen Matter.
