Home automation has come a long way from the days of simple garage-door openers and lighting timers. Today, whole-house control systems, like the AuroRa System
from Lutron, let you turn on groups of lights throughout the house from one master control or wireless remote. A system such as this, for example, allows you to enter and exit your home safely at night: You can turn lights off after you leave via remote and illuminate the entry and front hallway when returning. Some lighting controls can be hooked up to home security systems and will turn on all the house lights if an alarm is sounded.
