I have updated my OpenHAB to 2.5.12 and updated my Fritzbox to FRITZ!OS 7.25.
Now I have connection to my Fritzbox 7590 its online, but no Smart Home device is online.
I deletet everything and uninstalled the Binding. Then I installed the Binding again. But only my Fritzboxes where found.
What can I do to have my Smart Home devices again?
AVM did some changes in the login process (Version 7.24 / 7.25).
TR064 Soap Error after upgrading Fritzbox to 7.25
Oh my god, that was the problem.
I created a new user and now I can see my smart home devices in my inbox.
Thank you very much.
