In case I haven't already mentioned, we are having the Clipsal CBUS system :)
Our home will have the ability to be locked up and left easily for holidays. The Clipsal CBUS system controls the lighting, irrigation and blind automation so the house will always look like someone is home.
The best feature is the "master off" button at the exit points which turns all of the lights in the house off.
We are having three touch-screens throughout the house, from which we will be able to control the whole house (lighting, security system, audio etc):
And these switches (instead of the normal light switches) throughout the house, from which we will be able to control up to 8 functions:
