Automation on KNX

Hello,
I’ve been setting up my Home Assistant Green over the last few weeks and now I’m getting to work on the automations.
I use Home Assistant in conjunction with KNX, so the heating control runs via a KNX actuator. Now I have created an automation that reduces the heating in the bedroom to 18°C ​​in the afternoon, and that works great.
Unfortunately, the control up to 22°C cannot be implemented with automation. The value is simply not transferred.

Does anyone know why the value can be adjusted down but not up?

Hi :wave:!
I’d recommend to have a look at the group monitor while calling that action manually from Open your Home Assistant instance and show your service developer tools with a specific action selected.
If you don’t see anything, have a look at the Open your Home Assistant instance and show your Home Assistant logs.
