Integrate Intertechno Window Contact into OpenHAB

[Loidt]

I think I can answer the question myself. It looks like that receiving of signals is not supported by CUL Intertechno Binding for now as you can read here:

Support receiving of intertechno with a-culfw

There is an alternative culfw which supports also reception of intertechno events. https://github.com/heliflieger/a-culfw It would be great if the binding could support this. What would be necessary to support this?

I solved this issue by buing window contact from Homematic.
