With a tap or slide of your finger, you can switch lamps on and off, adjust brightness, and tune color temperature. Create and name groups according to room or situation, and coordinate dimming, color, and temperature settings. Program your lamps via gallery view: For visual control of your lighting, take a picture of your lamp(s) and room(s), save in the Gallery, and integrate luminaire control in the photo(s). Create and time-set light settings and scenes: Use the Grau app to program and save light scenarios for every mood and situation. Set the light right for working, meeting, dining or downtime and save the settings as a scene. Then simply select the scene you need with one tap. Grau timer function lets you configure lamps and lighting scenes according to time, date, or sunrise / sunset. Share your light network and lighting control: Grau has four different levels of sharing and access control. You can decide if your network is open to everyone, or if others need a password to access.
