We have two similar bindings here, both for the same hardware, each with its own advantages.
The vendor of the hardware is ABB and Busch Jäger, they both sell the hardware with their own label, but it is exactly the same.
Here are the two links from the openhab community for the two bindings:

I am using the openHAB 4.1.2 Release build and both bindings at the same time and this is the content of my /usr/share/openhab/addons:
org.openhab.binding.freeathomesystem-4.0.0-SNAPSHOT.jar
org.openhab.binding.freeathome-4.0.0-SNAPSHOT.jar
@laursen are you sure that the bindings have been mergerd or renamed?
