For OpenHAB 2 I now added as well the cube controller (Magic Controller). You can get the current version as a jar from here: https://dl.dropboxusercontent.com/u/2377534/org.openhab.binding.mihome-2.1.0-SNAPSHOT.jar
Merge request on openhab2 is here: https://github.com/openhab/openhab2-addons/pull/1660
Hope it will get merged at some time.
