Moin
Nur für den Fall das sich jemand - so wie ich - auch fragt was das ist/soll. 
Heute morgen hat mich eine Fehlermeldung und eine Warnung im HA Core Protokoll begrüßt:

Can't read Supervisor data:
Also ein Grund mal nachzuschauen was da los ist. 
Ich nutze hier noch HA Core 2025.10.4 mit HAOS 16.2, aber bekanntlich macht der Supervisor mit den HA Standardeinstellungen ja “sein eigenes Ding” und installiert irgendwelche Updates automatisch. Das ist dann bei mir - lt. Supervisor Protokoll - heute Nacht passiert:

die auf den ersten Blick so gar keinen Sinn ergeben, weil ich die darin genannten Add-ons gar nicht nutze.
Eine Suche im HA-Forum ergab dann das das Add-ons sind die alle erst noch ein Update brauchen, eben weil sie mit Supervisor 2025.11.4 sonst Probleme machen.
There are a bunch of add-ons in the community add-on repository that need updating. Just ignore it. Especially if you don’t use them.
Warum bei einer HA Installation, bei der diese Add-ons gar nicht installiert sind, dann diese Warnungen im Supervisor Protokoll auftauchen, oder auftauchen “müssen”, werden wohl nur die HA Entwickler selber wissen.
