Not sure if this board is still being used, but I am starting a home automation project. My ultimate goal is to create an enterprise style server/client solution that provides control over all devices from a PDA. Linux would host the server, using MySQL as its backend data storage, a custom designed Apache module for the front end, the custom C X10 library for the communication with the X10 devices. The Linux box will double as the gateway between the client and the X10 devices.
However as a sub project I wish to recreate the X10 SDK in C targeted at Linux. I estimate that this sub project will take about 2 months, assuming I get help from X10 with their hardware specifications. ie baud rates, signals and the like.
If anyone drops by and reads this post and has any information or wishes to contribute please contact me.
