Thank you for your support, highly appreciated!
I should of course have checked the logs - I don’t understand why I only focused on ETS and it’s traffic…
Regarding the climate entity issue, when I change the setpoint temperature in HA I get the following in HA logs:
2023-09-29 10:58:44.081 WARNING (MainThread) [xknx.cemi] CEMI Frame failed to parse: <CouldNotParseCEMI description="APDU LEN should be 0 but is 16 from 1.1.255 in CEMI: bcf011ff19000003f110002a19dcb80c52cd891d8e18c1fb" />

ETS does not show any traffic (however I believe yesterday I got a messages on the bus, but now I am uncertain).
For the sensor issue, I see the following when the sensor periodically sends it’s temperature (3/0/0) and humidity (3/6/0) values:

I have attached a image below of the date seen from ETS.
On row 18 the heating controller requests the temperature and the sensor replies on row 19. On row 14 and 15 HA does the same (both temperature and humidity), but without any reply. The messages also look different (“Sec” instead of “GroupValue_Read”). From the same period, I get the following logs. Please note that for some reason there is a minor time skew between the applications.
