Home Assistant Connect ZBT-1 (Zigbee and Thread USB adapter)

Home Assistant Connect ZBT-1

The Home Assistant Connect ZBT-1 is the easiest way to add Zigbee support to your Home Assistant instance.

A future firmware update will bring Thread support; this allows Connect ZBT-1 to be used to connect to Thread-based Matter devices.

Home Assistant Connect ZBT-1 is hardware-wise exactly the same device as Home Assistant SkyConnect. It's basically the same device with a different name. The only thing that will change is the logo on the product and packaging and the EAN code. Hardware and feature-wise it's 100% the same.

The Home Assistant Connect ZBT-1 is compatible with the Raspberry Pi and other Home Assistant-supported Linux devices. The Home Assistant Connect ZBT-1 will allow you to easily set up and use Zigbee sensors and devices with your Home Assistant install, allowing even more automation and integration options for your home.

The adapter uses the same Silicon Labs chip used in the Home Assistant Yellow device (Silabs EFR32MG21). A USB extension cable is included in the package to avoid interference caused by USB 3.0 ports.

Why include a USB extension cable?

USB 3.0 ports (the ones with blue on the inside) are known to cause significant noise and radio interference to any 2.4Ghz wireless devices. This includes Zigbee and Thread. If you do not use the extension cable, it may not work at all, and if it does, it could be flaky at best with intermittent problems (issues with pairing, device dropouts, unreachable devices, timeout errors, etc).
