[Enhancement] Replace tvservice with vcgencmd

[anmith]

Hi,
as tvservice always needs the virtual console thing, how about replacing it with vcgencmd?

/opt/vc/bin/vcgencmd display_power 0

turns off display power while

/opt/vc/bin/vcgencmd display_power 1

turns the power back again.

Hi @anmith,
i think you're right. Here is my working vcgencmd-Replacment:

https://pastebin.com/5n8zqL5a

Just copy&paste this into this file:
/home/pi/MagicMirror/modules/MMM-PIR-Sensor/node_helper.js
and replace the whole existing code there.

Maybe it helps someone and hope it finds a way into the master branch of this module @paviro?

Hi,

I wanted to create a PR with some changes I made for resetting the timer when someone is still standing in front of the mirror. I will include the vcgencmd, too.
So hopefully this finds its way to into the master branch.

Edit: There it is: #42

PR #42 works great for me.
