Verbindungsabbruch ohne Internet

[palKNX]

Hallo zusammen,

wir hatten letztes Wochenende über zwei Tage hinweg kein Internet. Eigentlich hätte ich erwartet, dass ich über OpenHab trotzdem meine KNX-Anlage steuern kann. Leider ging das nur zeitweise.
Nachdem sich nach dem DSL-Ausfall erstmal alles aufgehangen hat, habe ich das ganze System neugestartet. Danach konnte ich die Beleuchtung etc. auch erstmal schalten. Allerdings ging das nur für einige Stunden. Danach ging wieder nichts. OpenHab liefert die folgenden Fehlermedlung.

Kann das jemand bestätigen? Warum funktioniert das nicht ohne Internet?
Als Schnittstelle haben wir eine SCN-IP000.01

Vielen Dank für Ihre Hilfe.

Das kann ich definitiv nicht bestätigen.

Meine Vermutung wäre, dass durch den Internetausfall der Router zeitweise die Adresszuweisung mittels DHCP verk.ckt hat.
Abhilfe wäre, allen Geräten feste IP-Adressen zuzuweisen (zumindest denen, die ohnehin immer die gleiche IP haben sollten, also alle "Server" und Gateways.

[palKNX]

Ich bin eigentlich der Meinung, dass ich das gemacht habe. Ich werde es aber noch mal prüfen und gebe eine Rückmeldung.
Schon einmal vielen Dank.

[palKNX]

Es war tatsächlich keine feste IP vergeben Ich war mir total sicher, dass ich das gemacht habe.
Habe auch gleich OH eine feste IP verpasst. Vielen Dank
Dann warten wir mal den nächsten DSL Ausfall ab
