Pairing not possible with enocean actuators (FSB61,FUD61,FUD14)

Hi All,

maybe i’m getting it totally wrong here or all of my Eltako enocean devices quit their job!
I’m trying ot pair either a FSB61, FUD61 or FUD14 but in non of the cases the devices being recognized by openhab during the pairing process. On the other hand, if i click a rocker switch(FT55) while automtic enocean binding process, it’s being recognized in no time.
I’m using the USB 300, which has been installed automatically as gateway on setup on a Raspi 3+. I do have a second image with a working FHEM where every device can be controlled.
Please advise or is there a step by step Tutorial?
