PIR motion works but screen ceeps alive

hmoed

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

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.

sudo apt-get install x11-xserver-utils unclutter
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!
