KNX IP-Gateway with KNXD on Raspi4 and Openhabian doesn't work

Hi all,

I want to setup a Raspi4 with an USB KNX interface as IP-Gateway.
This is my system freshly downloaded and installed yesterday:

  • Platform information:
    • Hardware: Raspi4, 4GB
    • OS: current Openhabian
    • openHAB version: stable
  • Issue of the topic:
    I installed on a fresh system KNXD with the openhab config tool and configured it to use an USB KNX interface. KNXD is running and accessible locally with: “knxtool vbusmonitor1 ip:localhost”
    Badly, it is not reachable from ETS4 via my network.

What could be wrong?
Many thanks in advance…!


  • Please post configurations (if applicable):
    The KNXD configuration is:
    KNXD_OPTIONS="–eibaddr=0.0.5 --client-addrs=0.0.6:8 -d -D -T -R -S -i --listen-local=/tmp/knx -b usb:"
