Philips Hue lights can mimic your presence, copying your lighting habits from the moment you arrive home to when you go to bed. To make it look natural, randomness around your selected times will prevent the lights from coming on every day at exactly the same time and warn off unwanted guests. Based on your location, specific lights turn on and off when you arrive or leave home. Works with other smart home devices such as security cameras to look out for your home so you don't have to. When your compatible smart camera sees movement, your Philips Hue lights can turn on as if you're at home. A great way to scare off potential intruders.
