Home Assistant Bundle

The Home Assistant Connect ZBT-1 (formerly known as SkyConnect) is designed to be a perfect match for Home Assistant Users. The device provides an easy connection with Zigbee and will support Matter specifications in the future with a firmware update from Home Assistant*. The product supports Over-The-Wire (OTW) Firmware Update via the USB interface, which allows easy and quick firmware updates for both protocols.

The device is an EFR32 Series 2 (Silicon Labs EZSP v8) adapter that will transmit at a power of +20 dBm. The drive supports full-speed USB 2.0 when plugged into the included USB extender.

Home Assistant will soon add Thread support; allowing your Home Assistant ZBT-1 to be used to connect to Thread-based Matter devices

The USB Stick will be Plug and Play, tightly integrated with the Zigbee Home Automation integration allowing for a beginner-friendly experience.

* The ZBT-1 will not run Matter immediately on launch, but when using Home Assistant, the firmware will be updated to enable Matter when it is finished being developed. This is due to the Matter protocol not being finalized and released until November (not all of the protocol specifications are currently available). Home Assistant is already working on the Matter implementation, but more information will come after November.

Works seamlessly with HomeAssistant Green. Simple install, works perfectly.

Bruce Friedman
Installed on Home Assistant

Installation was simple and straightforward. Following advice on the card, I did install using the extension cord to move the radio a little further away from the PC.

Works well

Haven't had any issues with it so far and setup was a breeze
