    xaal.knx

    This package contains a xAAL gateway for KNX BUS.

    Software

    The datapoint mapping (dpts.py) come from the Smarthome.py software : https://mknx.github.io/smarthome/plugins/knx.html (GPLv3.0)

    Install

    You can use both pip, with pip install xaal.knx or setup.py

    You can test the package with : python setup.py develop (or install) --user

    To run the gateway: - edit your config file (~/.xaal/xaal.knx.ini) - launch python -m xaal.knx

    run :

    If you use an USB (serial) port, you can use knxd to forward commands between serial & multicast.

    to build knxd : git clone https://github.com/knxd/knxd.git ./configure --enable-usb --prefix=/opt/knxd --disable-systemd

    sudo knxd -t 1023 -e 0.0.1 -E 0.0.2:8 -i -R -S -b usb:

    This configuration doesn't work out of the box. For an unknow reason, knxd doesn't forward knx frame to serial port. Please read this bug report (fix)

    https://github.com/knxd/knxd/issues/340

    Supported datapoints

    You must use one of this in the configuration file.
