NanoCUL with Intertechno Binding

Hello,

I am trying to control my intertechno devices with OH. Therefore, I bought the nanoCUL USB Stick FTDI CC1101 433MHz FW 1.67.

The nanoCUL is on USB0:

[21:36:56] openhabian@openHABianPi:~$ lsusb
Bus 001 Device 004: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC

Dialout seems correct:

[19:34:05] openhabian@openHABianPi:~$ ls -l /dev/ttyUSB0
crw-rw---- 1 root dialout 188, 0 May 14 21:29 /dev/ttyUSB0

My binding config:

############################# Intertechno Binding ###################################
# Devicename to use (mandatory)
# Example /dev/ttyACM0
device=serial:/dev/ttyUSB0

# How often should the command be repeated? (optional)
# See http://culfw.de/commandref.html for details
#repetitions=6

# How long should one pulse be? (optional)
# See http://culfw.de/commandref.html for details
#wavelength=420

I am operating Intertechno modules that uses the V3 protocol. I have installed the intertechno binding and created (for testing) the following items:

Switch Intertechno "Group"        { culintertechno="type=v3;id=01101011000011110000000000;group=1" }
Switch Intertechno2 "Channel"     { culintertechno="type=v3;id=01101011000011110010011011;channel=15" }
Switch Intertechno3 "RAW" 	  { culintertechno="type=raw;commandOn=FF00FF00FF;commandOff=FF00FF00F0" }
Switch FLS "FLS" 		  { culintertechno="type=fls;group=I;address=3" }
Switch Classic "Classic"	  { culintertechno="type=classic;group=I;address=3" }

If I switch on or off, the RX light of the nanoCUL blinks one time brightly and a second time very short. Unfortunately the intertechno modules seems not to receive a valid code. Althoughthough they are in learning mode! Also my old 433 MHz Gateway, which is able to learn intertechno codes, isn’t receiving anything from the CUL?

Any ideas what I am doing wrong? Why is the RX light on the CUL blinking and not the TX?

I have spent some days on testing and trying now, so I am thankful for any help!

What does the log tell about the binding and the CUL.
