Home control, also called home automation, allows you to control most of the devices within your home (e.g. lights, air conditioning, microwave,
surveillance cameras, ...) from everywhere within or outside
your house. It will also allow to automate often used
sequences of commands and even enable you to have your home
flashing like a discotheque (though probably not for long).
First realisations exists with e.g. X-10, but except for some new office buildings and homes of real enthusiast it is not yet there.
