Remotely dim and control your home's lights from your iOS or Android mobile device using the HS220 Smart Wi-Fi Light Switch with Dimmer from TP-Link. The HS220 features built-in 2.4 GHz Wi-Fi connectivity, allowing you to use TP-Link's Kasa mobile app to access your lights from anywhere there is an internet connection. You'll be able to control the brightness of your lights in any room as well as set the ambiance for any activity. The app also allows you to schedule your lights to go on or off at certain times and set countdowns. It has an away mode that will randomly turn your lights on and off while you are away to make it look like your home is occupied.
