- added conversion from vdc type and usage to ds type 50
- treat every sensor of type 50 as zone assigned sensor so it is taken into account in heating controller
This is a proposition of solving the problem, but I am open to other propositions (like not needing to be a zone sensor, or add to dss a way to show and assign this sensor type to zone).
Also the vdc type 1 and usage 3 as the encoding for type 50 is just a guess/proposition. @brano could you also look at this?
