Comment

In issue #405 the DPT type was changed from 14.058 to 9.006 to support a weather station from a different manufacturer. Is it possible, to allow both types to support this station as well?

Hi 👋!
Since this is a read-only group, I guess we can even use DPT detection based on payload-length - like we do for climate setpoint_shift. So we wouldn't even require a new config attribute.
Unit of measurement is Pa for both, so that is fine too.
