Hi there,
I’d like to add a sensor using a knx group adress with DPT_Beaufort_Wind_Force_Scale ( DTP 20.014). Currently this value type is missing in the list. A comparable topic seems to be KNX add support for missing DPT 19.xxx 20.xxx from Juli 2023 but seems still unresolved
Perhaps better to open a bug ticket for the integration on github no ? instead of creating a duplicate Feature Request no ? 
Not in the home-assistant repository though - that’s only intended for bug reports, not for feature requests.
The xknx repository would be an appropriate place. GitHub - XKNX/xknx: XKNX - A KNX library written in Python
