How to use the Fibaro Keyfob and to manage challenges around it

@OMR
Can you tell me how you updated to 2.3.0? (openhabian) The installation steps in the readme doesn’t work for me (see my post here)

I then tried to download a 2.2.x version of the z-wave binding but I couldn’t find any (only the 2.3.x version).

thanks
Stefan
