The Home Assistant Connect ZBT-2 is the easiest way to build a Zigbee or Thread network — now with even better performance and stability. The precisely tuned, high-performance antenna and the latest-generation MG24 radio chip together provide faster response and a stable connection to connected devices. It is built on the open, second-generation Connect platform, making it well-optimized and aesthetically fitting for the home environment.
Setting up and migrating the ZBT-2 is essentially plug & play: Home Assistant’s built-in wizard guides you through the initial steps, allowing you to start a new Zigbee or Thread network in minutes or migrate your existing one. It directly connects a wide range of Zigbee 3.0 or Matter (Thread) devices to Home Assistant — without separate hubs.
