Siri API for the Gira HomeServer app

[migabc]

I figured out what was wrong: ;-)

The TUL must be programmed to work as a TPUART device (it does not work like a USB device as is the case of the GIRA KNX-UBS interface):

Here's the procedure I used to get it working as a tpuart device (might be useful for somebody)

Programming TUL (TP-UART USB Light) adapter

1) Install the TUL programming software (dfu-programmer)

sudo apt-get install dfu-programmer


2) Fetch the Firmware

sudo wget -O TPUARTtransparent.hex http://busware.de/tiki-download_file.php?fileId=54

3) Flash the TUL:

#Note: I found that it was not necessary to press the program button on the bottom of the TUL

Run:
sudo dfu-programmer atmega32u4 erase --force
sudo dfu-programmer atmega32u4 flash TPUARTtransparent.hex
sudo dfu-programmer atmega32u4 reset
sudo reboot


The TUL will now show up as: /dev/ttyACM0 which is owned by root


4) Change device ownership

Run:
udevadm info --attribute-walk /sys/bus/usb/drivers/cdc_acm/*/tty/ttyACM0 | grep KERNELS | head -3 | tail -1
< will return KERNELS==“something”>

Add the following line to:
sudo vi /etc/udev/rules.d/90-knxusb-devices.rules
...
# busware.de TUL (TP-UART USB Light) adapter
SUBSYSTEM=="tty", ATTRS{idVendor}=="03eb", ATTRS{idProduct}=="204b", ACTION=="add", KERNELS=="something", SYMLINK+="ttyKNX1", OWNER="knxd"


Note: you need to replace the something with whatever udevadm displayed above


Force new settings:
sudo udevadm test /sys/bus/usb/drivers/cdc_acm/*/tty/ttyACM0


Verify that /dev/ttyKNX1 exists and belongs to "knxd":
ls -lL /dev/ttyKNX1


The TUL will now work as a TPUART device:


5) Add -b tpuarts:/dev/ttyKNX1 to the options in /etc/knxd.conf.

sudo vi /etc/knxd.conf

cat /etc/knxd.conf | grep ^KNXD_OPTS
KNXD_OPTS="-e 0.0.100 -E 0.0.101:7 -D -T -R -S -i 6720 -b tpuarts:/dev/ttyKNX1"


6) Restart the knxd

sudo systemctl restart knxd


Check /var/log/syslog for errors:
tail -f /var/log/syslog


Check that is it listening on port 6720:
netstat -na | grep 6720


7) Test your KNX address groups (example address group 0/0/3)


Turn ON light:
knxtool groupswrite ip:localhost 0/0/3 1



Turn Off Light:
knxtool groupswrite ip:localhost 0/0/3 0
