How to uninstall matter / is it blocking HAOS 11 install?

Hello,
a while back I installed the matter beta to see what I could learn. In the end it failed to do anything and I went back to connecting to the matter smart plug via the HomeKit integration. I have since been ignoring the broken service.

Today I was running some updates, the latest core ran without issue, but the HAOS 11 failed.

Could the matter error be blocking the HAOS update?

Current software levels:

Home Assistant 2023.10.3
Supervisor 2023.10.0
Operating System 10.5
Frontend 20231005.0 - latest

Matter Integration:
Shows this in the integrations section

Similar error is logged during startup

Addon core_silabs_multiprotocol with version latest does not exist in the store

I didn’t see those messages until I tried the HAOS upgrade.

The above exception was the direct cause of the following exception:

Before trying to diagnose further the HAOS upgrade failure, I would like to delete matter integration. Know ZHA and Matter are closely related. So are there any risks to my ZHA integration if I just press the (Matter) uninstall button?

I have a similar issue, I’ve installed MatterServer Beta a while ago and now I want to deinstall it. I’ve stopped the server, disabled the service, but after a reboot the MS server is back again. Any thoughts how to permanently remove the server?

Problem solved for me:

  • stop MS server
  • prevent it from auto starting
  • disabled the service
  • deleted the service (UI->Settings->Devices & Services-> three dots)
  • deleted the integration

Now, after a restart, the Beta server is gone…
