Long before the smart home, people automating for convenience included motion sensors and photoelectric cells to monitor the level of light. It gets dark; the lights come on. Lights hooked up to motion sensors only come on when something the size of a small child moves around in its detection range. Of course technology has advanced and you now have digital timers, dimmers, flashers and even wifi control. You should put lights at every door or window that could be used to enter your house and boost your home’s safety and security even if you are not there.
