The Home Assistant Connect ZBT-2 is a USB adapter designed to act as a Zigbee and Thread coordinator for your smart home. Built by Nabu Casa, this device uses a Silicon Labs MG24 chip for wireless communication and an ESP32-S3 to handle the USB-serial bridge, ensuring it works smoothly with ZHA, Zigbee2MQTT, and OpenThread Border Router. It supports Zigbee 3.0 and Thread, which allows you to integrate Matter devices that rely on the Thread protocol into your ecosystem. To ensure a stable connection across your home, the adapter features a large omnidirectional antenna with a peak gain of 4.16 dBi, standing 164 mm tall. The hardware is housed in a white and semi-transparent polycarbonate plastic enclosure measuring 83 x 83 x 179 mm and weighing 157 g. It connects via a USB-C port, drawing 5 V DC at 500mA, and comes with a 1.5m USB-C cable to help you position the coordinator away from interference. This setup is ideal for users who want a reliable, high-performance bridge to manage a wide variety of smart sensors and switches.
