I'm creating an Android Things device using a Raspberry Pi 3, which will be connected to monitor. The monitor should be on all of the time, but I'd like a way to "turn off" the device (turning off the HDMI output so that the monitor can go to low-power standby mode) so that I can turn the device on and off remotely or with a timer, rather than having to manually push the monitor's power button.
Is there a way to control the Raspberry Pi's HDMI output (turn the display on or off) in an Android Things project?
