Test

Logon to docker container and test with knxtool

docker exec -it knxd bash

knxtool on ip:127.0.0.1 0/1/50
knxtool off ip:127.0.0.1 0/1/50

create UDEV Rule for /dev/knx

• Show the attributes of your KNX device. e.g. udevadm info -a -p $(udevadm info -q path -n /dev/ttyACM0)
• Note some unique attributes e.g. idVendor, iDProduct, serial and note them down
• Create a new udev rule: sudo vi /lib/udev/rules.d/99-usb-knx.rules and put a line with SUBSYSTEM=="tty", ATTRS{idVendor}=="03eb", ATTRS{idProduct}=="204b", ATTRS{serial}=="-your-serial-id", SYMLINK+="knx"
• Reload udev rules: sudo udevadm control --reload-rules && udevadm trigger
• Re-Insert KNX device
• Now you should have a device /dev/knx which you can use for this docker container which links to your knx device
