Solved
The adress to the binding was incorrect. Openhab created two bindings for my RFX, and one of them didn’t work 
Hi,
I have a raspberry 2 running Openhabian and I can’t get my RFX to send signals. I’m getting the error message below.
I think I’m not getting the JD2XX to work and I don’t know how to blacklist the ftdi_sio module (or even if I should)
The only USB I have beside the rfxtrx433e is a Z-wave.
Hope someone can help me
Regards Fredrik
