      This is not really a module for the MagicMirror application itself, but I wrote it for my own mirror and I want to share it, if anybody has use for it.

      I wanted a turn-off-my-display-control that is independent from the MagicMirror application. It turns off the display after a given countdown time from the last time a motion was detected by a PIR sensor.
      So every time a motion is recognized, the countdown is set to the maximum countdown time. When no motion is noticed for that time, the display is set to sleep. When then a motion is detected, the display is turned on.

      I also provide a systemd service file, if you want to use it as a service.

      If you have use for it, I put it on GitHub:
      [card:deg0nz/MagicMirror-Display-Controller]

      NOTE:
      If you’re looking for an integrated (and probably easier to use) solution, please take a look at paviro’s awesome PIR-Sensor module.

        @Beh Thx for sharing! One question : what are the physical settings to apply to the sensor itself pls? (Jumper & the 2 knobs)

          Example configurations for wiring are shown here:

          and here:

          https://www.raspberrypi.org/learning/parent-detector/worksheet/

          I can’t really tell you the jumper and knob configurations, because I’m using a simple sensor like this:

          Maybe you look in the PIR HOWTO thread or ask a question there:

            @Beh i see thx! maybe it’s better to use your one to somehow bypass these settings which are a bit frustrating. i did’t really get the systemd option (i am new) but as i understood it’s like a crontab, correct?

              @bibi No, it’s more like having it added to the autostart (like on windows). Then it’s running as a service in the background, which can be controlled via systemd’s systemctl command.

                    @beh hi! i was wondering if there was an easy way to add a fading effect when the mirror goes to sleep and wake up? would be interesting in this as well? thx

                      Hi @bibi, I hope, I understand that right.

                      I don’t think that this is very easy. Because the script just turns the HDMI port of the RaspberryPi to on and off. So a fading effect wouldn’t be quite easy I think
