The EIB / KNX bus can be accessed via the eibd daemon. The original distribution at TU Wien is no longer maintained. The work has been taken over on SourceForge.

Before all, make sure you have installed an xPL hub and a control user.

Install eibd

Install the necessary packages:

su
cd /tmp
wget https://sourceforge.net/projects/bcusdk/files/pthsem/pthsem_2.0.8.tar.gz/download
tar -xvf pthsem.tar.gz
wget https://sourceforge.net/projects/bcusdk/files/latest/download?source=files -O bcusdk.tar.gz
tar -xvf bcusdk.tar.gz

Install the packages:

cd pthsem*
./configure
make
make install

cd ../bcusdk*
export LD_LIBRARY_PATH=/usr/local/lib
./configure --without-pth-test --with-mctx-mth=sjlj --with-mctx-dsp=ssjlj --with-mctx-stk=sas \
--enable-onlyeibd --enable-eibnetip --enable-eibnetiptunnel --enable-eibnetipserver --enable-groupcache
make
make install

cd 
echo "/usr/local/lib" > /etc/ld.so.conf.d/bcusdk.conf
ldconfig
touch /var/log/eibd.log
chown control:users /var/log/eibd.log

Start the daemon and listen to messages:

su control
eibd -S -D -i --daemon=/var/log/eibd.log ipt:192.168.1.204
ps ax | grep eibd | grep -v grep
groupsocketlisten ip:localhost

Perform a write in a second terminal:

groupswrite ip:localhost 1/1/1 1
groupswrite ip:localhost 1/1/1 0

End the test back in the first terminal:

^C
pkill eibd
ps ax | grep eibd | grep -v grep

Install xPL EIB bridge

Download the eibd write and eibd read scripts.

Move the script to xPL scripts directory:

SCRIPTS_BASE_DIR=/home/control/Documents/Controls
mv xpl-eib-eibdWrite.pl $SCRIPTS_BASE_DIR
mv xpl-eib-eibdRead.pl $SCRIPTS_BASE_DIR
chown control:users $SCRIPTS_BASE_DIR/*.pl
chmod 775 $SCRIPTS_BASE_DIR/*.pl

Test xPL EIB writer

The test is shown here on a Linux machine such as a BeagleBone. It has to be slightly adapted on Mac OS.

Open a first terminal window (on any machine with xPL installed) and monitor the xPL protocol:

SCRIPTS_BASE_DIR=/home/control/Documents/Controls
$SCRIPTS_BASE_DIR/xpl-monitor.pl -vf

If the eibd daemon isn't running, launch it in a second window:

su control
eibd -S -D -i --daemon=/var/log/eibd.log ipt:192.168.1.204

Then launch the eibd monitor:

groupsocketlisten ip:localhost

In another terminal window, start the xPL EIB writer:

su control
SCRIPTS_BASE_DIR=/home/control/Documents/Controls
$SCRIPTS_BASE_DIR/xpl-eib-eibdWrite.pl -v -n home

Open yet another terminal and send a message to the EIB tunnelling server:

su control
SCRIPTS_BASE_DIR=/home/control/Documents/Controls
$SCRIPTS_BASE_DIR/xpl-send.pl -v -t cmnd -d dspc-eib.home -c eib.basic group='1/1/1' data=0x01

This should turn on EIB device 1/1/1. The groupsocketlisten window should show the eibd write command.

Test xPL EIB reader

Open a first terminal window (on any machine with xPL installed) and monitor the xPL protocol:

SCRIPTS_BASE_DIR=/home/control/Documents/Controls
$SCRIPTS_BASE_DIR/xpl-monitor.pl -vf

If the eibd daemon isn't running, launch it in a second window:

su control
eibd -S -D -i --daemon=/var/log/eibd.log ipt:192.168.1.204

Then start the xPL EIB reader:

SCRIPTS_BASE_DIR=/home/control/Documents/Controls
groupsocketlisten ip:localhost | $SCRIPTS_BASE_DIR/xpl-eib-eibdRead.pl -v -n home

Push on an EIB button or send a message to the EIB tunnelling server:

su control
SCRIPTS_BASE_DIR=/home/control/Documents/Controls
$SCRIPTS_BASE_DIR/xpl-send.pl -v -t cmnd -d dspc-eib.home -c eib.basic group='1/1/1' data=0x01

The EIB activity should appear in the xpl-monitor.pl window.

Launch the xPL EIB interface at startup

The EIB writer is to be launched after the xPL hub. The EIB reader is launched as a pre-start script.

Ubuntu

Edit /etc/init/xpl-eib.conf:

Start the device and test it:

su root
killall eibd
service xpl-eib start

su control
SCRIPTS_BASE_DIR=/home/control/Documents/Controls
$SCRIPTS_BASE_DIR/xpl-send.pl -v -t cmnd -d dspc-eib.home -c eib.basic group='1/1/1' data=0x01
$SCRIPTS_BASE_DIR/xpl-send.pl -v -t cmnd -d dspc-eib.home -c eib.basic group='1/1/1' data=0x00

Reboot the PC and check for the daemons:

ps ax | grep -i xpl | grep -v grep
initctl list | grep xpl
