Hi, thanks for the info concerning the first part.
I installed it according to your guide and received the first error. I then deleted it completely and reinstalled it again from scratch, again exactly according to your guide and received the following log:
==> /var/log/openhab2/openhab.log <==
2018-02-18 20:24:10.869 [ERROR] [home.handler.FreeAtHomeBridgeHandler] - Can not connect to IP gateway
2018-02-18 20:24:10.876 [ERROR] [home.handler.FreeAtHomeBridgeHandler] - javax.xml.bind.JAXBException: class rocks.xmpp.extensions.httpbind.model.Body nor any of its super class is known to this context.
I used the “installer” account.
Edit: One thing that could be a problem is, when it was installed, the electrician created an admin account, and there was no “installer” account. Don’t know if he deleted it, or if it was never there, but that might be the cause. I recreated it, gave it installed credentials and then used it to log in and tried my main account as well. Both don’t work.
I tried to log in multiple times and once received the following error, otherwise, I am getting the before mentioned error.
