I am using redhat linux with my CM11a interface to control the X10 controllable lights and appliances in my house. This allows me to setup intelligent macros, and schedules that closely reflect my work schedule. In addition to scheduled macros I have installed motion sensors in various locations. At night when I climb the stairs the light automatically comes on for me and after 2 minutes without movement the light shuts back off. I have managed to interface the CM11a to a web page allowing for graphical control of lights from any computer in the house. This could lead to attaching a computer to TV to allow graphical control from any TV in the house as well.
