Problem - Opener with SIEDLE BTS 850-02

Hey there, I have a Problem with the Config of the Opener with my SIEDLE.
Everytime I came to the step that I have to Ring the doorbell and Hit Button - Open door - in the App, nothing Happend. I checked several time the wiring.

Could someone help me please?


Did you solve the problem? I have exactly the same problem with mit nuki opener and BTS-850-02.
