Hey guys,
i am currently running Openhab on a Raspberry Pi 3 with a simple 433Mhz Sender and Receiver. Switching ELRO sockets is no problem. The next thing i wanted to test is a ITL-250 LED Dimm Device of Intertechno. For this reason i bought a ITT-1500 sender which’s signal i tried to receive and decode with 433Utils. This, unfortunately, is not working. So maybe someone knows a workaround for this?
That would be pretty great.
Kind Regards to all of you,
Max
Sorry, no workaround here but a device which I use for the ITL- 250:

Thank you for your answer. How do you integrate the shown device in openhab?
The Code for the self-learning intertechno devices is shown here: http://www.fhemwiki.de/wiki/Intertechno_Code_Berechnung
But my know-how is too less to get it implemented in 433Utils, etc. 
Thank you! Unfortunately the Tinkerforge Brick, Bricklet system is way too expensive for my project. I am trying to do home automation as cheap as possiple. 
I integrate my Intertechno devices (ITS-150, IT-1500, PAR-1500…) last week with pilight. Here is very good german tutorial -> http://raspberry.tips/hausautomatisierung/raspberry-pi-pilight-mit-433mhz-modulen-zur-hausautomatisierung/
I use the cheap Intertechno devices for my christmas lightning e.g.:
Switch Intertechno12 "Weihnachtsbeleuchtung Küche" <light> {exec=">[ON: pilight-send -p kaku_switch_old -i 12 -u 1 -t] >[OFF: pilight-send -p kaku_switch_old -i 12 -u 1 -f] "}
when you use piligh you have use ‘kaku_switch_old’ as protocoll instead of ‘intertechno_switch_old’ (or something like that although the receiver showing this protocol)
Thank you for the reply. I solved it with decoding the 433Mhz signals bits and writing my own protocol.
But your solution with pilight is more professional i think, haha.
I got them to work, but I knew the codes already from fhem.
I have not yet figured out how to determine new codes…
