I have a KNX Binding and I successfully use OpenHAB to switch on and off my lights, and to move my rollershutters up and down. But I don’t seem to find a way to control its postion or to use them in groups or give other commands.
I think the problem starts at the Group Address at the KNX Binding in Paper UI itself. All my rollershutters have this type of Group Address:
My third rollershutter has the GA UpDown 1/0/3, StopMove 1/1/3
My fourth rollershutter has 1/0/4 and 1/1/4
And so on.
How do I find what I can fill in as Group Address for the exact position?
And will that open up a world of possibilities?
I don’t use a *.things, only a *.items and a *.sitemap.

In fact, you can use both options at the same time. But in question of position, it’s unusual to control absolute position directly in knx.
A more common way to control position of multiple blinds in knx would be to configure knx scenes.
So, I’ll recommend two exclusive GA per actuator channel, one for control position, the other for position status. This way you’re able to control the position and get the actual position, may it be a command originated from openHAB or from knx.
Actually I use the absolute positioning through Alexa voice commands and (very seldom) in my UI.
With button switches it’s impossible (or you have to buy expensive wall controllers) and having scenes is the way to go. But utilizing my Echo it is quite useful.
I second your setup with separate addresses for position and setpoint, I had proven useful for me that way too.
Thank you both for your inspiration. I found out in ETS that there are no configured group addresses for position and positioning. I will try to add them and then add those addresses in the OpenHAB binding.
I’m using scenes so OH3 is always guessing if they are open or closed.
This is the reason why I’m also using the absolute position now, in this case GA “<1/1/12”.
But OH3 is still guessing, e.g. first it jumps from 0%->100%, after a stop between it jumps back from 100% to e.g. 35%. I think it is the autoupdate features. Can I somehow disable it in OH3?
