PIR motion works but screen ceeps alive



  • 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
    }

    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!
