KNX integration fails with update 2026.1.x

Hi There,

I have this version of KNX


with homeassistant 2025.12.4

When I update to version 2026.1.x my knx integration stops working:


I read over the release notes but I dont know what I can do.

Does anybody can support me what to do?

Perhaps…

Hi :wave:!
It seems something has messed up your python libraries.
HA 2025.12.4 would require xknx 3.11.0, HA 2026.1 requires xknx 3.13.0. You seem to have 3.8.0 loaded in your screenshot.

Tbh, I don’t know how this can happen in a normal installation. HA should handle the install of requirements - unless you run some custom component that overrides it.

hm what would be the best solution in this case? My System runs several years now, had never an issue. I regularly do updates within my HASSIO. shall I login via ssh bump the version first to 3.11 by hand?

Try starting in safe mode to see if xknx version is correct then. If it is, I think you would be using a bad custom component.
Bumping packages by hand should never be required.

So I tried to boot in safe mode on this point it loads correct 3.11.0 version of xknx

Then you probably have some flaky custom component installed that loads a wrong version!?

I updated now to current version, and than restarted into safe mode. this fixed my version issue so far, knx is back again. Not sure how this happened

and without safe mode?

Maybe a bit more detail:

  • Version of HA 2025.12.4 → wrong xknx version
  • Reboot of HA into safe mode → fixed xknx version issue
  • Reboot of HA into normal mode → version issue stayed fixed (correct version)
  • Update HA into 2026.1.3 → xknx wrong version
  • Reboot HA into Safe mode → xknx version was ok
  • Reboot HA into normal mode → xknx version stayed OK
  • Dashboard was corrupt
  • Cleared Browser Cache
  • Everything is fine
