MyStrom Binding

Dear community,

I’m new to openhab - installed openhab 2.1 on raspi and so far quite happy.
I have an issue that I want to integrate my “MyStrom Wifi Switches” into a rule (experimental rule engine) but I am so far not able to get the .items created correctly. I’ve tried the follow the binding configuration but so far no luck.

Can anyone advise on how to include a MyStrom switch in openhab 2 ?
