Fibaro Motionsensor not sending Events / Values

I am new to openHAB and have set up an installation on my NAS with a Z-Wave USB Stick.

I was also able to connect the Fibaro Multisensor FGMS001 and link the items e.g. for motion sensor and temperature. During the first test some motion detection events where triggered and logged into events.log. But values for luminance, battery were empty in the PaperUI or are not being updated. So I tried to change the settings but got an HTTP error - (as described here

[ERROR] [ome.io.rest.core.thing.ThingResource] - Exception during HTTP PUT request for update config at 'things/zwave:device:ec189443:node2/config' for thing 'zwave:device:ec189443:node2': For input string: "org.openhab.binding.zwave.internal.protocol.ZWaveAssociationGroup@4539cd6f"

So I removed and reconnected the sensor multiple times (by resetting the sensor Hard-Resetting and the Z-Wave USB-Stick), but now I did not get any event for motion detection and temperature and battery values are empty.

Do you have any idea on what I habe maybe missconfigured?

Here is some debug output when someone steps into the motion sensor area:
