Homematic OCCU no devices

Configuration
1

Hi!

I use the Hass.io Homematic OCCU extension with the HM-MOD-RPI-PCB module on my RPI, but cannot manage to see the devices in Home Assistant.
In the Homematic OCCU console I see the communication between the Homematic components and HM-MOD-RPI-PCB.I see the changing state of the window contacts.

The configuration.yaml part for Homematic looks like this:

# Homematic
homematic:
  interfaces:
    BidCoS-RF:
      host: core-homematic
      port: 2001

The discovery option is set.

Do I have to configure sensors and switches on my own, or what did I forget?

Thanks in advance!
