Does Home Assistant Green support Zigbee and Thread devices?
The Home Assistant Green does not come with built-in Zigbee and Thread.
To integrate Zigbee or Thread-based smart home devices with Home Assistant Green, you’ll need a compatible Zigbee/Matter radio adapter—and the Home Assistant Connect ZBT-1 is the go-to choice for many users.

The key points:
