Light schedules for home automation
Philips Hue can make it seem like you're home when you're not, using the schedule function in the Philips Hue app. Set the lights to come on at a pre-set time, so the lights are on when you arrive home. You can even set rooms to light up at different times. And of course, you can let the lights turn off gradually in the night, so you never have to worry whether you've left any lights on.
