I see 2 climates control (UML FBH and UML HK1). They should popup into HA.
I don’t know what is “WVF” (function = 15 ?). Maybe it’s your MultiWin+ heater ?
You can explore the OIDs by change de prefix in the query :
Example for the WVF node :
curl “http:///api/1.0/lookup/1/20” --digest -u USER:{pass}
