So the conditions I found in the existing ETS config (2 GAs for 2 switches) is not common then?
I am using the demo verion at the moment to learn.
Unfortunately I don’t have the original knxproj file, but only a downloaded one without “meta data”.
That’s why I created the table to get a better idea about it’s structure without changing something.
Thank you - I will check this out (I just started with the Voltus stuff from “haus-automatisierung.com”)
Unfortunately I played too much and the actuator is not in run mode anymore.
I guess I messed it up 
I used the original knxproj file to revert back (upload application), but failed.
Possibly the best way is to take the course and start from scratch as the system is not too complex…
Thank you for your help!
I might come back with more questions
