Wemo light switch lets you easily set automatic schedules for any light. Using the free Wemo app, you can schedule your lamps to turn off at sunrise, or synchronize your front light with the sunset so you never come home to a dark house. Protect your home with randomized lights. When set to ‘away mode’, the smart light switch will turn plugged-in lights on and off randomly. Pair it with Amazon Alexa or Google Assistant built-in devices like Google Home to turn your lights on or off with just the power of your voice.
