The intended hardware configuration is to have a Raspberry Pi connected to an Arduino using a USB port on each device. The Arduino is then connected to and x10 interface like the TW523/PSC05, PL513/PCS04 or in my case the XTB-IIR. More on the XTB-IIR later.
The Arduino runs the x10serial.ino file and requires the X10 transmission library developed by Tom Igoe. This library is available on GitHub at https://github.com/tigoe/x10
The x10serial.ino recieves commands over USB used as a serial port from the Raspberry Pi and sends them in x10 format to the x10 interface. The Raspberry Pi could do this itself but I felt it was better to off load the low level interface to the Arduino in order to run a webserver an other struff on the Raspberry Pi.
x10serial.c is a commandline program that is used to send commands out the USB serial port. It was created so that it could be call by cron or using at commands.
Daily.php is run a few minutes after midnight each day to do sunrise and sunset calculations and then to schedule the x10 commands using the at command.
The XTB-IIR can be found at http://jvde.us/xtb. This site provides kits. I chose the XTB-IIR because it is also a boster and repeater and I have alot of noise on my powerline. This interface works great and has provided reliable service for several years.
