All my matter/thread devices are Unavailable. They have worked for about a year. At odd times when devices were Unavailable, restarting add-ons and reloading integrations has fixed it, but not this time.
Is there a trouble shooting guide somewhere?
My Matter/Thread devices are:
- 3 Nanoleaf NL67 Lights and
- 2 Eve Energy 20ECF6001 Smart Switches and
- a Home Assistant Connect ZBT-1.
My system is:
- Installation method Home Assistant OS
- Core 2025.5.3
- Supervisor 2025.05.1
- Operating System 15.2
The OpenThread Border Router add-on has some failure messages, but I don’t know how serious they are; and the Matter Server add-on is full of serious looking error messages. Should I post long logs here?
Here’s just a bit of the OpenThread Border Router add-on log, enough to show it is accessing the Home Assistant Connect ZBT-1 OK.
Thanks for any pointers.
