With the Smart Wi-Fi Dimmer: you can control the ambiance of any space with the push of a button. A quick tap of the switch toggles lighting to the previous level and built-in up & down dimmer buttons let you fine tune lighting to match your mood or activity. Because it's a TP-Link Smart Switch: you can easily control it from anywhere using the Kasa app or your favorite voice assistant device. The Kasa app also guides you through each step of the installation: connecting your smart dimmer to your home Wi-Fi.
