The Sonoff Zigbee Bridge Max, also known as the Bridge-M, serves as a central hub for managing a smart home ecosystem. It functions as both a Zigbee gateway and a Matter bridge, allowing you to connect and control up to 128 Zigbee devices from a single point. This capacity makes it suitable for larger homes where numerous sensors and switches need to work in harmony. Connectivity is flexible, as the hub supports dual-band Wi-Fi at 2.4GHz and 5GHz, alongside a physical RJ45 Ethernet port for those who prefer a stable wired connection. For users who value privacy and independence from the cloud, it includes an integrated local web interface for configuration and management. The device integrates seamlessly with Apple Home, Amazon Alexa, and Google Home, and it is compatible with Home Assistant via MQTT. Designed as a compact white rounded hub, it is powered via a USB Type-C port. When paired with compatible Zigbee sensors and cameras, it can trigger a siren reaching 90 dB to alert you of security events, providing a practical layer of protection for your living space.
