Control your lights from anywhere with the HS210 Smart Wi-Fi Light Switches 3-Way Kit from TP-Link. Thanks to Wi-Fi connectivity, a hub is not required for operation. With the Kasa Smart app for iOS and Android, you'll be able to set light schedules that suit your needs. Away mode turns your lights on and off at random, making it appear that your home is occupied. These smart devices can replace traditional three-way switches.
