KNX clima not possible to set temperature

Configuration
1

Hi, I have a couple of eelectron tc17b01knx controlling both heathing/cooling fan coils as well as only cooling fan coils.

I get the correct temperature reading from another binary input device (Theben TA 6 s) but the setpoint does not seem to work, I cannot chnage it in the climate control, it is “grayed out”. Se image:

I have tried using both setpoint_shift_address and terget_temperature_address but the same problem. According to Eelectron support I have the right objects in the right groups. I am fairly new to KNX so there is probably something I miss here. Any ideas are greatly appreciated. Code (from knx.yaml) pasted below. Thanks!

climate:
- name: "Cornelia sov - FC1"
  temperature_address: "2/0/4"
  target_temperature_address: "2/1/4"
  target_temperature_state_address: "2/4/4"
  operation_mode_address: "2/2/4"
  operation_mode_state_address: "2/5/4"
  controller_mode_address: "2/6/4"
  fan_speed_address: "2/3/4" 
  controller_mode_state_address: "2/7/4"
  min_temp: 15
  max_temp: 26

I know from experience that the KNX climate does not work till it gets a value in the state address.

This only applies to setpoint_shift configurations.

its with the card. Till there is a value for the state address you cannot adjust with the slider.

Thanks, seting the base setpoint enabled the possibility to change the temp. Seems like I have to create an automation that does this on every restart of HA.

does your target_temperature_state_address not respond to read-requests?

I have the same observation and solution - restoring the target temperature after HA restart.
And I have checked with knx.read - it responds with current setpoint temperature but it is a bit specfic: the A/C unit is setting this temperature not exactly to the level I have requested it to be but relative to the measured return temperature. For example: at the moment room temperature is 22, I have set the setpoint temperature to 23 but because the return temperature is 23 the A/C unit sets the setpoint temperature 1 degree higher than the return temperature. And it adjusts the setpoint temperature automatically depending on current room temperature, setpoint temperature and return temperature.
With this setup I’m getting the room temperature (measured by external sensor) in line what I’m expecting but the downside is that I can’t use the read address with setpoint temperature in the HA climate entity configuration as it would always change depending on what temperatures are actually in the room and in the return temp. sensor in the A/C unit and therefore I need to restore it after every HA restart.

A bit complicated explanation but I’ve spent quite some time to figure out how to best configure it.

Btw, there is also one more downside of that. If I change the target temp with the IR remote that setting won’t be reflected in HA climate entities. So far I have not figured out how to address it…
