## What is Grau?

The Grau app is the easiest and most intuitive way to control your Grau luminaires. At the tap of a finger, you can create and program ideal light settings for every mood, space, time and situation.

Program and group your lamps in one view:
The Grau app lets you see all your Grau lamps in one view, build lamp groups, and program both individual and group settings. 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. If you have several users and devices using the same network, all changes made with one device will be automatically updated to the other devices via the Grau cloud service.
