OK I took a MiniPC with 32Gigs of memory and 1TB HD and decided to use it with HA. I bought the ZBT-2, ZWA-2, Sonoff_Zigbee_3.0_USB_Dongle_Plus_V2. That is the hardwear I am working with. I have been using SmartThings V3 hub. But tired of almost everyting in the cloud.
The Zwave [ZWA-2]& Zigbee [Sonoff_Zigbee]both work well. However, the ZBT-2 has been nothing but trouble. Getting Matter/Thread to work. When I first plugged in the ZBT-2 the blue light came on I loaded the thread firmwear and all went well. I tried to add a matter leak detector “and several other things” with no luck. they would try to load on both a Google & SmartThings but could not find the ZBT-2. I get this “Home Assistant Connect ZBT-2 (OpenThread Border Router)
Failed setup, will retry: Unable to connect” I go to ZBT-2 and it says “Home Assistant Connect ZBT-2 (1CDBD45F5448) Firmware turned off
2:50:36 PM - 42 minutes ago
Home Assistant Connect ZBT-2 (1CDBD45F5448) Firmware turned on
2:49:47 PM - 43 minutes ago
Home Assistant Connect ZBT-2 (1CDBD45F5448) Beta firmware updates turned on triggered by action Switch: Turn on
2:49:46 PM - 43 minutes ago” I first tried the standard firmware and gave up and tried the beta with the same results. I then tried disconnecting the Google thread router but that will not go away even after a reboot. I am at a loss as to what to try next.
What does this mean … who is “they”?
By they I tried several different Sensors Present, temperature, motion, open/close,etc.
I’m still unclear, but I think what you mean is that when you try and commission a device, you see somewhere that it is telling you that it is trying to commission device to a Google hub or a SmartThings hub, and if this is the case, then what is probably happening is that your Mobile device that you are using for commissioning has the Thread credentials for the Google Hub or Smartthings.
Are you using HA Companion app for Android?
I have the same issues. Using a NUC with Proxmox. Passed through USB connected ZBT-2. Showed up in HA and flashed as a Thread Border Router was set as Preferred Network. Set up Open Thread Integration and Matter all looked correct. Google Nest hub was seen also. Hand NO previous Matter devices. Proceeded to setup a Ikea Myggspray motion sensor. Install went well other than the Google Nest Hub ignored preferred network and installed it into HA. Though it worked well I do not want to use any of my google hardware. Now is where I went down the rabbit hole of trying to get the ZBT-2 working. Why no indicators that it’s ON. Proxmox shows it’s connected to the USB ports that are configured. Tried deleting Nest hub and uninstalled from Google Home. Deleted google home from my Phone. Then tried to resync the credentials with phone so it would update to HA credentials. Factory reset the IKEA and tried pairing. Now I have nothing. HA shows it then activity says ZBT-2 became unavailable and 5 sec later reports Turned Off. I give up, MATTER sucks. Worst experiance with any devices I have. I will reconfigure the nest hub and use it. I will keep the ZBT-2 in hopes that some day it will work. Please put some kind of indicator that it has POWER when configured as a Thread border router. I assume the turned off means that just the radio is off. Sorry for the rant.
I am experiencing the same issue, where the ZBT-2 keeps turning off (has OpenThread RCP 2.4.4.0 firmware installed). I don’t have any other devices on my network that support the Thread Border Router functionality which helps simplify things a bit for me, but what I found helpful was to make sure my iPhone was connecting to 2.4 GHz wifi (temporarily disabled 5 & 6 GHz bands on one of my access points and bound my phone to it). I then unplugged the ZBT-2 for a few seconds and plugged it back into my HAOS server, and was then able to add new Matter devices. The antenna still keeps turning off, but devices are responding. When adding new devices, I still unplug the antenna for a few seconds and plug it back in. Previous steps I had taken included making sure IPV6 was enabled on my network and in HA. The antenna is certainly not a plug and play device, requiring a lot of tinkering.
