I find that dedicated displays are great, but it seems very wasteful to have the display on all the time. It wastes power and also damages the display with burn-in.
Are there ways of turning on the display only when people are present?

An app that subscribes to MQTT topic to trigger screen on event. I have MQTT PIR-sensors. App would run in the background, and would hopefully re-connect to broker, etc.

I see apps that use the camera, but that only works when the lights are on. So it’s not the best solution. Also, it’s pretty processor intensive.
