Hi @Woogi,
first of all I have to say, that I do not know the old enocean binding. However to interact with your physical enocean things, you first have to pair your openhab things with your physical ones (eg teach in). So you could try to activate the learning mode of your device and switch your OH2 button afterwards.
However you could also use my new openhab2 enocean binding, which supports a brider range of EEPs as the old one. You find the discussion about it here.
Best regards
Daniel
