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!
