MMM-PIR-Sensor tuning

[Jopyth]

@KirAsh4 I agree with you, but it also depends on what we are debugging. I looked at the particular way @jc21 implemented it, and it seems all the debug information are shown in the process manager logs only.

[KirAsh4]

I’m not saying it’s wrong, nor right. I just prefer to use one facility that will show everything, as opposed to one that might only show some things.

[jc21]

I agree, a central place for logging info would be ideal but that’s just not possible with MM at this point.

This is a bit out of scope for this topic, however unless you’re across the module system in depth you may not be aware that there are 2 separate “processes” to the MM for lack of a better word

• The UI, electron app that uses console.log and outputs to the chrome dev console if active
• The Server App, express & module node_helpers that uses console.log to output to stdout of the process

With the way MM module system is implemented, using any additional NPM packages required by a module can only be done on the NodeJS App side (as far as I’m aware?), not in the UI where the browser dev console log is available.

That said, for this module particularly, if the UI was started with the dev console option then when motion is detected or no longer detected, the Node JS App will log a USER_PRESENCE socket event where the value will either be true or false respectively. This is the case for both the original github repo and my fork. Unfortunately the dev console event system doesn’t log the value so debugging on/off values is not possible:

calendar received a module notification: USER_PRESENCE from sender: MMM-PIR-Sensor

I don’t use PM2 yet, but to start the MM with dev console on just add the dev argument:

electron js/electron.js dev

@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?

[jc21]

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.

[shgmongohh]

@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.
