This device works as EITHER a zwave or thread device. NOT BOTH. I tried to change it after the fact and it was a dead end.
Hello Frank,
Thank you for reaching out and sharing your experience with the ZBT-1.
I apologize for any confusion—first off, to clarify, the device supports Zigbee or Thread protocols (not Z-Wave, which may have been a mix-up in the initial feedback).
We're committed to transparency, and our product page explicitly states that it operates as either Zigbee or Thread, with the following details:'The device provides an easy connection with Zigbee or Thread.'
'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.'
'Dual-Protocol operation (Deprecated, not recommended)'
Nowhere on our site do we indicate or promise simultaneous Zigbee and Thread support.
That said, if you've spotted any wording that could be misinterpreted, please point it out so we can review and update it promptly.For firmware options, you can flash any available version, including the deprecated dual-protocol one, via this guide: https://home-assistant-skyconnect.netlify.app/firmware-update/.
Custom firmware uploads are also supported if you'd like to experiment further.
If the device isn't meeting your needs, we're happy to process a return. Just follow the steps here:
https://ameridroid.com/blogs/ameriblogs/payments-returns.
Our team will handle it quickly once we receive your submission.
Please let me know if there's anything else I can assist with—I'm here to help.
Best regards,
Brandon
