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.

Great price and promot shipping.

Communication has been great too. Install went smooth.

Great Product.. after updating it.

So far the product has been great. Unfortunately it wasn't plug and play as expected. I plugged in the dongle and Home Assistant did not recognize it.
After a long search in the forums it turns out a batch of them was made without property setting the USB identity so Home Assistant didn't recognize it as a SkyConnect.
The instructions to update the device were in the forums and fairly easy to update. It just took me a while to figure out the problem.
Once that was taken care of the device has been working fine so far.

Does what it is supposed to.

Easy install

It worked as easy as was advertised. I have not had any troubles with it since I installed it. I used it to connect my Aqara mini buttons and water leak sensors. Allowed me to get rid of the Aqara hub and app.
