For sure this is an older thread, but I’m also having some issues with this.
I coupled my knx with an ubbink ventilation system, that’s working fine and I do have (at this moment) 4 settings I can choose from (like 25-50-75-100%), all working fine with a press on the button.
I even managed to make it possible with HA to manage my fan by making it seen as a dimmable light. Pressing around 50% will turn it to 50% as an example.
But… While i do get feedback when I press in HA on a value (I can see it change on my MDT Glastaster), I don’t get any other feedback on my other devices.
- pressing on my HA-app on my smartphone does change the value + I see this on my wall-device
- pressing on my wall-device will change the value, but I don’t get any feedback on my smartphone
- pressing on my smartphone will not change the value in the HA-app on another device like my tablet or laptop.
Still will experiment some around, I do hope to find an (easy) way around this.
