We are looking at mixing a PIR (motion sensor) with a Raspberry Pi, such that the screen will turn on when motion in sensed and then sleep after a certain period of no sensed motion. The screen will be connected via HDMI and the OS will be Raspbian Jessie on a Pi 3.
What methods are available to be able to tell the display to wake and then put it stand-by?
For the timeout it appears /etc/kbd/config, with possibly:
Is this the right way to go about this, if the desktop environment is Pixel?
For wake, I am not sure? I will be using nodejs, if it makes a difference. Additionally, are there any other methods to have a Pi reduce power consumption on periods of inactivity?
