Hi guys.
A short summary of my configuration bevor explaining my problem.
I’m using a Raspberry Pi 2.0 with Hardware Revision B. At the Moment I’m using Rasbian Jessie as OS. Directly to the RPi there is a RFXtrx433E attached on the USB port. I’m running OH 1.8.2.
We’ve multiple windows which are shaded by Somfy rollershutters. These are controlled by the Somfy RTS remotecontrol. I’ve learned all controls to the RFXtrx as RFY device with the Windows application RFXmgr. When I’m trying to control a rollershutter with this application everything is working like a charm. (on the RFX device there is first the red LED on - I think it’s a sign for sending Data- and after 1 or 2 seconds the green one for a short time)
After this pre-configuration I attached the RFX to my RPi, copied the binding file in the addon Directory and configured the USB Port ttyUSB0 in my openhab.cfg.
After this I’ve added an item to the default.items and created the responding part in the default.sitemap.
default.items
Rollershutter RsJalOG {rfxcom=“>0.02.13.1:RFY.RFY:Shutter”}
default.sitemap
Switch item=RsJalOG label=“Jalousie”
When starting OH in debug mode I see that the RFX is initializing with the following lines:
19:42:56.169 [INFO ] [.b.r.internal.RFXComConnection:112 ] - Connecting to RFXCOM [serialPort=‘/dev/ttyUSB0’ ].
19:42:56.250 [DEBUG] [i.internal.GenericItemProvider:341 ] - Start processing binding configuration of Item ‘RsJalOG (Type=RollershutterItem, State=Uninitialized)’ with ‘RFXComGenericBindingProvider’ reader.
19:42:56.280 [DEBUG] [.rfxcom.internal.RFXComBinding:63 ] - Activate
RXTX Warning: Removing stale lock file. /var/lock/LCK…ttyUSB0
When I’m pressing e.g. the button for moving up or down the rollershutter first I get the following lines and only see the green LED flashing shortly:
19:43:39.216 [DEBUG] [.rfxcom.internal.RFXComBinding:91 ] - Received command: RsJalOG DOWN

And after a few seconds this line appears:
19:43:44.264 [ERROR] [.rfxcom.internal.RFXComBinding:239 ] - No acknowledge received from RFXCOM controller, timeout 5000ms due to java.util.concurrent.TimeoutException: waiting timed out
And now the question is how to fix it. 
Hopefully there is somebody who can help me and makes me happy.
Thanks in advance.

It is very simple.
