Works flawlessly with RaspberryPi & pilight & InterTechno products

simply connect with 3.3V (5V not without voltage divider so that the RPi not get back 5V - can withstand only 3.3V)
Remote control (I ITS 150) Upon reading it just to the recipient. (You can also wire solder for better reception, but if you just read for the radio codes need the recipient and no longer is not required)

Raspberry Pi configuration:
---------------------------------------

1. Install pilight) ---> Version 5.0 made "SSDP connection" problems .... Version 6.0 works !!!
To choose which version is installed:
--------------------------------------------------
Step 1.) piight daemon -V // currently installed version queries
See Step 2.) sudo apt-cache madison pilight // Available versions
Step 3) sudo apt-get install pilight = Version number -y // example: ..... pilight = 6.0 -y

2.) Start with "sudo service pilight start" first pilight, otherwise works "pilight-receive" and "pilight-Send" (best Enter a Startup)
3.) then by pilight-receive the remote read "id" and "unit" write code.
4.) "sudo pilight-send -p intertechno_old -i 2 -u 13 -t"
-p protocol used .....
-i ...... buttons #
-u ..... channel # (13 = N)
-t -f ..... ...... TURN OFF

Although he "eg archtech_switch" is displaying the log when reading the post "intertechno_old" to verweden ... certainly was in my case!
