Home Assistant Connect ZBT-2 - Zigbee / Thread adapter

Home Assistant Connect ZBT-2 is the simplest way to set up a Zigbee or Thread network - now with even better performance and stability. The precision-tuned, high-performance antenna and the latest generation MG24 radio chip work together to ensure faster response and stable connection to connected devices. Based on the second-generation Connect open platform, the device is technically optimised and aesthetically suitable for the home environment.

The installation and migration of ZBT-2 is practical plug & play: the built-in wizard in Home Assistant guides you through the initial steps so you can set up a new Zigbee or Thread network or migrate an existing one in minutes. The device directly connects a wide range of Zigbee 3.0 or Matter (Thread) devices to Home Assistant - without additional gateways (hubs).
