Thread Companion Apps issue

Configuration Matter/Thread
1

I’m running HA OS most up to date versions on a Raspi 5. It’s connected to my router by ethernet.

I had set up OpenThread Border Router with a SMLIght SLZB-7, with most current Thread Firmware ( Openthread RCP). OTBR is configured and running, Otbr-agent log file indicates: “Successfully sent discovery information to Home Assistant.”

The setup seems fine, Thread shows this screen

Matter Server is running. Log file seems fine apart from these two lines:

2026-02-21 15:58:04.165 (Dummy-2) CHIP_ERROR [chip.native.DIS] Failed to advertise records: src/inet/UDPEndPointImplSockets.cpp:417: OS Error 0x02000065: Network is unreachable

2026-02-21 15:58:04.170 (Dummy-2) CHIP_ERROR [chip.native.DL] Long dispatch time: 249 ms, for event type 2

If I check the status in my Android Companion App (Settings → Debugging → Sync Thread" I get the message “The home assistant server does not support thread”. Opening Thread Setting in my Android Settings does not show any Thread network.

I already cleared my Google Play setting four times, for each time also restarted HA.

I set up HA Companion App on a Ipad. Under Settings->Debugging->Thread I get an empty list. Adding a device by scanning the QR code open the HOME App, not HA.

I checked almost any thread here, on reddit and Simons community. It does not happen often, but Im not far from giving up. Any ideas where to look or what to do?

If the Thread credentials in debugging (Apple Keychain) is an empty list, it means you can’t use that mobile app for commissioning new devices.

You should be able to add your network to the Apple Keychain by clicking “Send credentials to phone” in on your device’s companion app Thread integration settings.

After that, don’t scan a QR code with your camera app. Instead, open HA companion app, and go to Settings → Devices → Add Integration → Add new matter device.

Thank @peterxian,
This really drives me crazy. My companion app on the IPhone is version 2026.2.1 and I have no “Settings” there. I see them in older videos but my version does not have them.
Same is true for the Android app which does not show any “Settings” as well.

Any suggestion where to find them?

Your user needs to be an Admin to access Settings → Devices from the companion app

Thanks @Shawsky that was the first part of the solution. You need to use your companion app as admin. The second part of the solution is, you must have enabled IPv6 on your HA. Now I was able to integrate a Matter device in a minute.

Thanks also to @peterxian for your helping hand!
