RFXCOM is online but no items

Hello

I have the problem that my RFXCOM USB-Stick is “online” but does not see my temperature sensors.
Actual Installation: OH2.1, RFXCOM 2.1, OpenHabian1.3
With my old installation OH2.0 and RFXCOM 2.0, no OpenHabian it worked .

The connection to my rfxcom seems to be good:
2017-07-26 13:54:41.916 [DEBUG] [g.rfxcom.handler.RFXComBridgeHandler] - Checking RFXCOM transceiver connection, thing status = ONLINE
2017-07-26 13:55:41.916 [DEBUG] [g.rfxcom.handler.RFXComBridgeHandler] - Checking RFXCOM transceiver connection, thing status = ONLINE

If I connect my rfxcom to the RFXmngr-SW I can see the data from my TEmperature modul! So for me it seems that the message is going out of the rfxcom but OH can not see it.

So I just checked my installation with OH2.0 and rfxcom 2.0. Here everything is working.

Does anybody know a solution? Do I need to make some changes to the user? I really do not know how to go on.

Thanks

Does no one has the same problem?

Does anybody use openhabian v1.3 with rfxcom 2.1 with openhab 2.1?
