openHAB 2 innogy SmartHome binding (ALPHA)

[zeitraubend]

Guten Morgen Zusammen,

erstmal ein großes Lob an Olli für das Binding. 
Leider bekomme ich es bei mir nicht zum laufen, nach der Installation und Initialisierung bzw. Anpassung der IP und des API Key's kommt das SH nicht online.

Anbei ein paar Screenshots und Fehlermeldungen.

Auszug aus dem Log:
