Systam Rooms Energy saver

You can set your Rooms displays to go into energy-saving mode outside of active working hours, saving up to 50% energy during quiet times. During active hours, the displays are at 100% brightness, and outside of these hours, the displays switch to energy-saving mode, which dims the brightness of the displays. 

Turn on the setting in the Dashboard under Settings/Energy saver. The setting is workspace-specific and applies to all displays in the workspace.

Additionally, define the start and end times of the active working hours.

When the device is in energy-saving mode, the normal brightness can be briefly reactivated by tapping the panel. This gives the user 10 minutes to interact with the device. After 10 minutes it will dim the birghtness of the display.
