This article explains how to turn off your screens remotely. This will not remove Valotalive from the screen but with this action you can put a Display to an interval if there is a need for it.
Go to Displays / All Displays
Locate the Display you want to put on an interval and click to open the settings.
Go to the Displays ACTIONS tab
Switch the Display on/off button to the OFF mode
Remove all Apps and/or Flows from the Display
In the end your Display should say that it has been turned off - before it is actually turned off
TIP! You might want to make a note to the Displays NOTE tab to let the other team members know what you’ve done to the Display and why
