Notice: The current batch of Connect ZBT-1 devices is not affected by the previous voltage regulator issue. All units are fully functional and verified to be issue-free! Only older batch 232401 (noted on the ZBT-1 box) used the faulty voltage regulators.
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 or Thread.

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 Connect ZBT-1 can also be used to turn your Home Assistant installation into a Thread border router. The first time that you connect your ZBT-1 to your HA Hub you will be prompted to select either Zigbee or Thread. If you want to install a different firmware please follow these instructions.
The USB Stick is Plug and Play, tightly integrated with the Zigbee Home Automation integration allowing for a beginner-friendly experience.

The ZBT-1 allowed my Home Assistant to connect to some Hue button control devices that had been invisible to it before. No Hue hub required. Good to know that other Zigbee devices will be similarly easy to integrate into Home Assistant.
Great communication and fair pricing!
so I had a great experience. It hooked right in to my home assistant green and I was able to connect a third reality contact sensor in moments. It's worked flawlessly since then.
You guys keep amazing me. This is a great addition to my Home Assistant Green setup. I pre-ordered the module and it was shipped as promised. Simple to install and provides more possibilities for integrating various devices to my home automation solution.
I added this to my Home assistant in a few minutes and am very pleased with the result.
