[eBus 3.0]: custom configuration Hautec heatpump with TEM controller

Hello, I have been using a 1.x ebus binding and used a custom .json file for my Hautec heat pump. Now i tried to update this to OH 3.

  1. The bridge is running and receiving telegrams
  2. I have added a new thing as “HautecWP”
  3. the “HautecWP” is receiving version informations from the controller (but has no channels)

But I do not see any values in my items / sitemap.

What could be the problem?
a) the fomat of the new .json file?
b) the channel definition in the items file?
c) missing channels in the HautecWP thing?

my items:

Number outsidetemp                      "Außentemperatur Heizung [%.1f °C]"    <temperature>  (Chart_Aussentemperatur)    { channel="ebus:bridge:84fa775f3d:08:common:temp_ouside"}
Number warmwaterIst                      "Warmwassertemp. Ist [%.1f °C]"       <temperature>     (Chart_Heating)    { channel="ebus:common:84fa775f3d:08:heizung:kessel_ist"}
Number warmwaterSoll                     "Warmwassertemp. Soll [%.1f °C]"      <temperature>     (Chart_Heating)    { channel="ebus:common:84fa775f3d:08:warmwater:temp_soll"}
