The whole room is dark when you get off from work at night, then you need to fumble around to find the light switch. With L510B & the Tapo app, you just need to take your smart phone out from pocket & open Tapo app, then everything is on. Worried about the house when your family is on a trip? This is where Tapo L510B Dimmable Lights functions. It turns on/off the lights randomly to simulate someone being at home. Connect the L510B Light to your home Wi-Fi network, then you are all set. No need for extra hubs or other devices.
