I am trying to integrate KNX with my Openhab-2 installation and everything works fine.
But I am some kind of stuck in my understanding of how to control my rollershutters with percentage.
I mean I can fully open and close every rollershutter and it works fine but if I try to close one for lets say 50% it will start to close but stops just before it is fully closed.
After using the ETS5 Bus-Monitor I can see that the messages about the current state of the shutter (7%, 14% and so on) are coming in with an delay of 3 seconds (Bus workload only 2%). I am able to see the message with the current position on the bus while the shutter is at 50% down which is in case of one window 15%.
If I then tell openhab to close the shutter 15% it stops at 50%.
I am pretty sure that this is no Openhab-Issue. The software of my smart-home vendor has the same problem but do you have an idea how to correctly solve this problem?
