A smart light switch lets you schedule your home lights to turn on and off at a set time, and make it look like you’re home when you’re on vacation. You can also connect smart light switches to other smart home devices, and program them to turn all your lights on if a smoke detector activates or your security system detects an intruder. These are just a few of the examples of the things that smart light switches can do. Smart switches can let you control an entire house’s lighting with one tap, whether you’re at the office, on vacation, or in bed for the night.
