Now you can be really, truly lazy, because Switchmate automates your standard light switch, no screwdrivers required. Snap Switchman over your existing switch, pair it with your smartphone, and then turn your lights on and off without ever leaving the sofa. When you do eventually leave the house, you can turn on your lights before you arrive home, thus avoiding any dark entryways (and potential tripping hazards). It’s held on by magnets, so it’s just about the easiest installation you’ll ever have, and, if you’re a renter, you can simply snap off your Switchmates to take them with you when you move.
