      host: core-homematic
      port: 2001
    wired:
      host: core-homematic
      port: 2000
    hmip:
      host: core-homematic
      port: 2010
    group:
      host: core-homematic
      port: 9292
      path: /groups

Raspberry Pi3

If you use the HM-MOD-RPI-PCB on a Raspberry Pi 3, you need to add the following to the config.txt file on the boot partition:

dtoverlay=pi3-miniuart-bt

HmIP-RFUSB

HassOS versions 1.11 and later support the HmIP-RFUSB by default and don't need any configuration. If you installed Hassio on another distribution of Linux, you need to follow the installation guide for the UART USB to setup the UART USB interface on your computer.
