Can’t connect Matter Thread device – Thread Hub/Bridge Required with ZBT-1 and Home Assistant Green

[formal charm]

Hi!

I have a Home Assistant Green and just bought the Home Assistant Connect ZBT-1 USB stick. I’m trying to add a MS-1 Smoke Alarm that uses Matter over Thread, but I get this error:

“A Thread border router is required for the device. Connect the border computer and then try to configure the device.”

I thought the ZBT-1 would work as a Thread device, but it seems it’s not being recognized as a Thread Border Router.
Also seeing this message:

“Thread Hub/Bridge Required”

How can I fix this? Do I need additional hardware, or should the ZBT-1 work as a Thread Border Router with Home Assistant Green?

Here’s the product link:

Thanks in advance!

please read this documentation from top to bottom. your thread border router credentials are not saved to your mobile device. https://www.home-assistant.io/integrations/thread/#case-1-making-home-assistant-your-first-thread-network

"You have no credentials to import"

@brisk osprey

[brisk osprey]

Is this iOS?

[formal charm]

No android

[brisk osprey]

Ok i just missed something
You're going through the process of importing credentials from your mobile device to home assistant. You should be going the other way around, in fact you're not at the right menu at all.

In the Companion app, go to Settings > Companion app > Troubleshooting, then select Sync Thread credentials

[formal charm]

Can you log in?

If I send you

[brisk osprey]

Log in what? I'm not remote customer support and that won't be any help anyways

[formal charm]

Ok

[brisk osprey]

You want to go to this page in the settings

Hit companion app and continue with the rest of the instructions

[formal charm]

This?

@brisk osprey

[brisk osprey]

Yes you can follow the rest of the instructions.

[formal charm]

@brisk osprey like that? do I need to do anything more?

[brisk osprey]

Try commisioning again now

[formal charm]

@brisk osprey you mean config/integrations/integration/thread?

Ah add my device?

Wow its working

I try to delete

What can I dp @brisk osprey

[brisk osprey]

i'm gonna be honest, i have no idea what happened here. post your logs from both the OTBR and Matter Server add-ons and maybe someone else smarter will know what happened.

[formal charm]

What should I do here

@brisk osprey

[brisk osprey]

ok i literally just said this is the end of my previous experience and that you should post logs for others to assist you. when you ping me after that you are being rude.

[formal charm]

Ok

How I find logs?

[brisk osprey]

When you go to Settings > Add-ons > Matter Server / OpenThread Border Router there will be a tab for logs you can download when you are at your computer and post here.

[formal charm]

Like that?

[brisk osprey]

yes that's exactly it.

[formal charm]

Ok..

[brisk osprey]

now despite my efforts i cannot decipher this. hopefully someone in the morning can understand this, i wish you luck

@brisk osprey Interference or conflict with another Thread Border Router
• You also have an Apple TV 4K as a Thread Border Router.
• Conflict may occur between two different Thread networks on the same LAN if the Apple TV and HA each try to control their own network.

. Temporarily disable Apple TV's Thread (if possible)
• If you can: log into the Home app on iPhone → Settings → Apple TV → disable Thread (if available)
• This minimizes the risk of Apple TV competing for control

[brisk osprey]

ah yes, iOS is a dick and will give Apple-made TBRs precedent over any other TBR on the network. This is why I initially asked if you were on iOS... but you're not, so this should not be an issue

@brisk osprey what addons should I have installed?

Matter server and?

[brisk osprey]

ok man i am ignoring you now because i have told you I am at the end of my knowledge and experience and I do not wish to be pinged.
I reiterate once more I am not customer support. I am just a bystander who offered some advice, and now I am out of said advice.
Do not ping me again, I will not read it or respond to it.

[formal charm]

Anyone?

Google is sometimes buggy, I usually do initial commission (setup) via HA Matter server Web console. You need a bluetooth dongle like $5 cheap. In this way, you can clear/bypass the issues from the controller (Google/iOS side).
