Using CUL Stick with NON Intertechno Devices


I have recently started with openhab and have set it up with a CUL Stick and some FS20 Shutter actors and one Intertechno Wall outlet.
These work well so far. But now I wanted to add some other Wall outlets (Similar to Intertechno but not the same Protocoll):

The devices are those:

I also found an implementation for wiringPI

As far as I see that, the intertechno raw mode can only send the tri-based Signals “0,1,F”, but these new Wall outlets I got there are working different.

It would be great to use these cheap Wall outlets in openhab!

maybe add some sort of RAW CUL sending feature bases on the “G” command of CUL instead of “is”?
Any ideas?
