I tried this
knx.items
Number A_EG_AZ_Aircon_setControl "Klima EG AZ Modus einstellen" (Klima) { channel="knx:device:tunnel1:AirCon:A_EG_AZ_Aircon_setControl" }
1st result: Same issue, ETS doesn’t realize anything from OpenHAB regarding get/set
2nd result: After restarting OpenHab, I see this in OpenHab when clicking through the control modes. Still the device doesn’t react.
I’m wondering about the most right column “Info”. Compared with manual setting/getting control mode, the values have a “$” sign and show the right DPT 20.105:
