Home Assistant Connect ZBT-1 is the new name for Home Assistant SkyConnect. Though it's a new name and look, they have the exact same hardware, capability, and support. We made this change to help make room for a new line of Connect products, specifically an upcoming Z-Wave Connect product. Going forward, whenever we mention updates or features for Home Assistant Connect ZBT-1, this will also apply to SkyConnect-branded devices. Retailers will continue to sell SkyConnect-branded devices while supplies last, and we would encourage you to purchase whatever is available as they are functionally identical.

USB 3.0 ports (the ones with blue on the inside) are known to cause significant noise and radio interference to any 2.4 GHz 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).

See demo on YouTube.

Our current recommendation for Home Assistant Connect ZBT-1 is to use the Zigbee firmware to power your Zigbee network. This solution offers a great experience out-of-the-box.

As part of our efforts to bring Matter to Home Assistant, we're now focused on ensuring that the Thread experience will catch up and become a first-class citizen, making it easy to connect to your Thread-based Matter devices in Home Assistant without a third-party Thread border router. The Thread firmware is already fully functional under the hood, but we still have some work to do to make the experience of using Thread-based devices in Home Assistant feel good. Once the experience has improved, we will recommend using this Thread firmware to power your Thread network as an alternative to using third-party Thread border routers from Apple or Google.

Multiprotocol will remain an experimental feature and is not recommended for use.

When we launched this device, we announced our intent to release firmware supporting multiprotocol, which allows the device's Silicon Labs chip to connect to both Zigbee and Thread networks with one radio.

This experimental firmware has been available since December 2022. Through extensive testing, we have found that although it works in some circumstances, it has technical limitations that lead to a worse user experience. We now do not recommend using this firmware, and it will be experimental for the foreseeable future. Instead, we will focus on making sure the dedicated Zigbee and Thread firmwares for Home Assistant Connect ZBT-1 deliver the best experience to users.

If you currently have the multiprotocol firmware installed but don't actively use it to connect to Thread devices, we recommend that you disable multiprotocol.

Nothing changes for current users of the multiprotocol firmware who are happy with their experience. The experimental multiprotocol firmware will remain available, but we will not recommend it to new users.

We’ve found an issue in Home Assistant Connect ZBT-1 that is the result of a faulty part incorporated in the first batch of ZBT-1 devices (sold between June and October of 2024). These devices can fail if plugged into certain USB-A ports, but can operate without issue if plugged into most devices.

We have instituted a program to provide a replacement device free of charge for a period of 60 months (effective October 2, 2024) for verified purchases. If it’s working, keep it plugged into the device it’s working with. The long coverage period means you don’t need to worry about a replacement until you require one. Regardless of whether the device has failed, we will provide a replacement upon request. SkyConnect branded devices are unaffected by this issue and do not require replacement.

Please contact the seller where you purchased your device, and they will arrange the return process and replacement. For more information on the program, read our blog
