<![CDATA[Power-saving modes?]]>How are people handling turning their screens on/off?

I’m running my mirror on an RPi3. It disables the HDMI port after a timeout and I’m using a voice command to turn it back on. The problem is that it takes almost 10 seconds for this to happen and, in the mean time, I have no way of knowing if the voice command actually worked until it turns on.

So, I’m looking for a better solution.

  • power saving with an infrared distance sensor
  • gesture control to toggle between MMM-pages, news, show news details and scroll through news page

It works with well for me, but needs some hardware: Arduino, gesture sensor, IR sensor.

I used that module as a reference and ran the commands manually…it still takes a long time BUT at least using a sensor could help a user more easily activate it.

Can I ask what sensor your are using?

I am using the module MMM-PIR-Sensor and a physical PIR-Sensor, which works great.
