Automation of an electrical system is fast becoming a popular option.  Not only can it reduce your power bill but it allows you to easily make changes to the operation of your entire system. C-Bus can operate things like your lights, Air Conditioner and blinds based on a schedule or by the amount of ambient light in the room.  Imagine being on holiday and having the ability to turn lights on from your phone, or leaving for work and with a single press everything is tuned off.  The possibilites are endless.
