I am ready to use lmce to automate some lights.
All of my lights are now wired to a central point in THE closet and are operated by relays and momentary switches.
So a really cheap sollution would be to use a weederboard with digital inputs to drive the existing relays.
There is allready some info in THE wiki: http://wiki.linuxmce.org/index.php/GSD_to_drive_a_Weeder_I/O_WTDIO-M
Making a fulltime functioning GSD device looks like a nice little project.
However, can you Guys think of reasons not to use it and go for an other solution like KNX?
I am asking because there is so little mentioning of weederboards on THE forums.
