xAAL devices for KNX bus

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)

Supported datapoints

You must use one of this in the configuration file.
