Control lights with a click: A simple touch of the button is enough to turn your lights on and off, cycle through scenes, and more. Press and hold to dim or brighten the space. Get the best light throughout the day: The button uses the Time-based light function by default, giving you the best light for each moment of the day. Customize in the app: Set the Rooms or Zone your button controls, adjust settings to control lights or start an automation, choose which scenes you want for each time slot, and more in the Hue app. Start/stop automations: Start or stop an automation created in the Automations tab with a simple press. Flexible, wireless mounting: Use the included adhesive to mount the button around your home — or place it on any magnetic surface.
