Fibaro FGS223 Problems

i´m actually switching from domoticz to openHAB. I installed openHAB SNAPSHOT on my Synology NAS DS216j running DSM6.1. My z-wave Controller is an AEOTEC GEN5 Stick.
System is running. I added the z-wave binding an the found devices as things. Item Linking is set to simple Mode as described in the tutorial.
In the control screen i se the two switches of the FGS223. But when i switch them, nothing happens. They get a red sphere after some time.
In domoticz they work fine.
What have i done wrong? How can i find the mistake?
