MMM-PIR-Sensor tuning

[shgmongohh]

@jc21
Sorry, I have some issues with your MMM-PIR-Sensor.
When I install your MMM-PIR-Sensor, my MagicMirror is slower, the MMM-Scheduler doesn´t work and the MM doesn´t stop with pm2 stop mm.
Any idea?

Do you experience the same thing with paviro’s original module? https://github.com/paviro/MMM-PIR-Sensor

@jc21
No with the “original” PIR-Sensor I don´t have this issues. That´s why I it noticed.

I have still the issue with the sensor, that it turns on the monitior at night, when nobody is there. I need a programm to track, how often this at night happens. If it is only one or two times at night or more often.

@shgmongohh Ok I’ll take a look at my stuff soon. I’m in the middle of writing another module that takes a photo when this PIR module senses user presence, if you had a camera attached it might be useful to you to see what the pir is detecting, if anything.

@jc21
Thank you. I don´t have a camera.
I don´t know if the sonsor works not correct or if I have another issue.

When I install your module, have I to delete or uninstall the other pir-module?
I only have renamed the folder.
If i have to delete it, how is it done?

I have found a python programm, where I can track the sensor in a consolen window. Has anybody an idea how i can safe the data into a document? And how I can autostart my python programm?

# Import required Python libraries
import RPi.GPIO as GPIO
import time
import datetime

# Use BCM GPIO references
# instead of physical pin numbers
GPIO.setmode(GPIO.BCM)

# Define GPIO to use on Pi
GPIO_PIR = 23

print "Bewegungsmelder Test (CTRL-C zum Beenden)"
print "========================================="

# Set pin as input
GPIO.setup(GPIO_PIR,GPIO.IN)      # Echo

Current_State  = 0
Previous_State = 0

try:

  print "%s: Sensor initialisieren ..." % datetime.datetime.now()  

  # Loop until PIR output is 0
  while GPIO.input(GPIO_PIR)==1:
    Current_State  = 0    

  print "%s: Fertig! Warte auf Bewegung..."  % datetime.datetime.now()    
    
  # Loop until users quits with CTRL-C
  while True :
   
    # Read PIR state
    Current_State = GPIO.input(GPIO_PIR)
   
    if Current_State==1 and Previous_State==0:
      # PIR is triggered
      print " %s: Bewegung erkannt!" % datetime.datetime.now() 
      # Record previous state
      Previous_State=1
    elif Current_State==0 and Previous_State==1:
      # PIR has returned to ready state
      print " %s: Fertig! Warte auf Bewegung..."  % datetime.datetime.now() 
      Previous_State=0
      
    # Wait for 10 milliseconds
    time.sleep(0.01)      
      
except KeyboardInterrupt:
  print " Exit"
  # Reset GPIO settings
  GPIO.cleanup()

It done. I can tune my PIR-Sensor.
Here is a usefull Link.

Hi, I’very been through a lot of the posts on the White Screen issue, and on this thread. I’m close… I can feel it, but I’ve an uncaught exception that I don’t understand.

link to screengrab.

Anyone offer any tips as to what might be causing this?

I’m on a Pi3 Model B v2.
Have only installed the standard mirror module, and the MMM-PIR module. The mirror is working fine and the PIR module is loading, but the screen isn’t switching off.

@open_book Few things,

1. What version of Raspbian are you using? The onoffnpm module has issues with some releases.
   Hint: cat /etc/os-release
2. What does your config look like for the pir module, exactly?

@jc21
1.
PRETTY_NAME=“Raspbian GNU/Linux 8 (jessie)”
NAME=“Raspbian GNU/Linux”
VERSION_ID=“8”
VERSION=“8 (jessie)”
ID=raspbian
ID_LIKE=debian

              {
		module: 'MMM-PIR-Sensor',
		config: {
			sensorPIN: 3,
			powerSaving: true,
			}
		},
