Control your home lighting from anywhere with your smartphone or tablet using the free Kasa app. Set lights to turn off and on at dawn, dusk, or any time that works with your daily schedule. Make it look like you’re home when you’re not by having your lights turn off and on randomly while away. Turn on or off the bulbs connected to the Smart Switch just using your voice with Amazon Echo, Dot, Tap and other supported devices(sold separately). Find the switch easily, even at night when all your lights are turned off. White.
