Bosch Smarthome creating things doesn't work

  • Platform information:
    • Hardware: Lenovo X1Carbon Intel CORE I7
    • OS: Windows10 with all actual updates
    • Java Runtime Environment:Microsoft Java11
    • openHAB version: 3.2.0
      I created my existing Bosch Smarthome using the Bosch Smarthome binding easyly as a Bridge. Now I want to create Bosch Smarthome in wall switches, door/window contacts, …
      But if I create anyone of these things (e.g. door/windows contact by selecting Bosch Smarthome Binding, Label Door/Window Contact, Bridge Smart Home Controller, Device ID SGTIN (24 Byte)) I get as a response all the time “invalid ID”. Last time I used the QR-code and used a copy of the integrated SGTIN as Device ID to avoid typos, but it doesn’t help.
      What’s my mistake?
