      this is my first post, so be gantle with me please… ;-)

      PIR motion works on test but my hdmi connected screen ceeps on, it will not going off.

      Some PIR Test info on Python Idle3:
      import RPi.GPIO as GPIO
      import time
      sensor = 4
      GPIO.setmode(GPIO.BCM)
      GPIO.setup(sensor, GPIO.IN, GPIO.PUD_DOWN)
      previous_state = False
      current_state = False
      while True:
      time.sleep(0.1)
      previous_state = current_state
      current_state = GPIO.input(sensor)
      if current_state != previous_state:
      new_state = “HIGH” if current_state else “LOW”
      print(“GPIO pin %s is %s” % (sensor, new_state))

      OUTPUT on waving to PIR:
      GPIO pin 4 is HIGH
      GPIO pin 4 is LOW
      GPIO pin 4 is HIGH
      GPIO pin 4 is LOW
      GPIO pin 4 is HIGH
      GPIO pin 4 is LOW
      GPIO pin 4 is HIGH

      Config.js:
      module: ‘MMM-PIR-Sensor’,
      config: {
      sensorPIN: 4,
      powerSaving: true
      }

      ON NPM Start:

      Whoops! There was an uncaught exception…

      MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?

      Settings:
      Edit /boot/config.txt
      set hdmi_force_unplug=1
      sdtv_mo=2 // Normal PAL

      sudo su
      /var/spool/cron/crontabs
      @reboot python /home/pi/Documents/PIR/pir.py &

      Also done:
      sudo apt-get update
      sudo apt-get upgrade
      sudo reboot
      in MMM-PIR-Sensor folder
      npm install
      sudo reboot

      what O what can it be ?

        I do remember that initially had some problems with my PIR sensor as well. It did not shut down the HDMI port properly. My personal problem was that I was not successful to disable the standard jessie screensaver.
        Once installing unclutter (sudo apt-get install x11-xserver-utils unclutter) and disabling the screensaver i got my PIR working perfectly.
        The error message in your log seems to indicate to me that is a resource conflict. Might it be possible that your are running your python script permanently and in parallel the PIR module ? And therefore causing the resource conflict ? Not sure whether this might be the case.
        One easy thing for debugging whether HDMI switching on/off is successful would be to install the remote control module. I did use this in my debugging phase to use the web interface of the remote control module to manually switch on/off the HDMI interface.
        Hope this helps, Steff

          thanks for the quick replay.
          I did instyall the unclutter for mouse pointer disable but not the way you discriped.
          I wil try what you typed above.

          1. sudo apt-get install x11-xserver-utils unclutter
          2. disabling the screensaver

          Afther that i take a look at the install of the remote control module.

          The Python script was only to show that the PIR is working outside MM2
          And i don’t run it the same time.

          i will inform back.

            back again,
            uncutter installed and is working
            remote controle module installed and is working from pc and my iPhone, top app.
            i can turn monitor off/on
            when i check the PIR on Python Idle3 it’s handeling motion correctly.
            BUT on the live mirror the PIR does nothing…

            HELP !

              The easiest way I find to disable the screen saver is to install xscreensaver and disable it! :) Quick and easy!
