Smart home solution
http://www.youtube.com/watch? v=6VxZXvzONv8 Here is a short video of a smart home solution made in India which allows one to control an electrical device using a browser. The solution consists of a master controller and multiple slave devices communicating using wireless protocol. The master connects to a PC using USB. User devices like lights, fans, TV, AC etc. are connected to the slave device. This enables the end-user to configure complex rules in his PC (the real "brain" behind the "smart home" in this solution) according to one's taste. Hence, the "smartness" of your home will no longer be limited by the "smartness" of individual devices.
