Finally my Raspberry Pi has arrived and I want to use it as the server for the perl based HomeAutomation server fhem http://fhem.de/fhem.html.
For the fhem set-up I followed the installation instruction as described under http://www.fhemwiki.de/wiki/Raspberry_Pi and this worked like a charm
The installation of the culfw firmware was a bit more tricky, but with the following steps I was able to flash the CUL to the latest version.
Download the firmware
sudo wget http://culfw.de/culfw-1.46.tar.gz
and unpack it
sudo tar -zxvf culfw-1.46.tar.gz
Change into your device directory (e.g. Devices/CUL)
Install the package dfu-programmer
sudo apt-get install dfu-programmer
Insert the device into the USB slot while pressing the micro-switch
sudo make usbprogram_v3 V3 to be used for CUL V3.
After flashing the CUL, a new USB device should appear: “03eb:204b Atmel Corp.”. If not re-insert the device without pressing the micro-switch.
The server is now up and running since several days. For the time being the server is just listening to the FS20 traffic in the air and logs it.
I want to control the FHT8v directly from this server without the need to use the FHT80b device which is originally intended to steer the valve controller. Normally this should be straight forward but a first test was not successful. I will publish the results once I have it running.
