Other configuration options

Keep screen on and prevent device from going to sleep

If you set the configuration option keep_screen_on_time to a value greater than zero, the screen is prevented from dimming or locking for the specified time in seconds.

If supported by the browser, this is done via the Screen Wake Lock API. The Screen Wake Lock API is usually only available when provided over HTTPS.

If the screen lock API is not available, a short invisible video is played in a loop instead to keep the screen on. Due to browser limitations, you must interact with the screen once to enable the screen lock after the Dashboard page loads.
