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 and the Tapo app, you just need to take your smart phone out from pocket and 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.
