MMM-PIR-Sensor tuning

[KirAsh4]

Most being the keyword, not all. And honestly, when I’m developing, I don’t rely on what pm2 is telling me, but rather specifically what the browser sees (or doesn’t) and where the errors lie. pm2 doesn’t do that. I can get all errors and debug messages in one place: the browser’s console log. I don’t need to open yet another window just to look at pm2’s logs.

[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

[shgmongohh]

@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.

[jc21]

@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?

Sebastian

[shgmongohh]

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()

[shgmongohh]

It done. I can tune my PIR-Sensor.

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.

[jc21]

@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?

[open_book]

@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,
			}
		},

[jc21]

@open_book Very strange, it seems the module is trying to activate/deactive the monitor using the Relay, but you haven’t specified a relay to use.

I have noticed however, that sensorPIN of 3 shouldn’t work. This variable is incorrectly named, it is not actually the pin number of the header, but the GPIO number instead. Refer to this Pi 3 image showing which “pins” correspond to “gpio” numbers. You should be using one of 4, 5, 6, 12, 13, 18, 22, 23, 24, 25, 26 or 27.

For example, a sensorPIN of 4 would require the PIR io cable plugged in to pin header 7.

[open_book]

@jc21 hi again, thanks for your input so far.

I’ve had the sensorPIN at 22 previously. And tested it using the python script shared on a few other threads:

´´´python
from gpiozero import MotionSensor
import os

pir= MotionSensor(22)
while True:
if pir.wait_for_motion(timeout=10*60):
print(“It lives”)
else:
os.system(“/opt/vc/bin/tvservice -0”)
´´´
The result spammed “It lives”. Which I understand to mean that the sensor is working… If I change the if to “os.system(”/opt/vc/bin/tvservice -p")" the screen shutsdown.

The reason I changed it was based on the results of “gpio readall”. I currently have power in pin 1 (3.3v), ground in pin 6 and data in pin 15

gpio readall tells me that physical 15 = BCM 22 = GPIO 3 so I decided to try sensorPin: 3.

I’ve changed it back to 22 now, but the result is still the same.

Other possible vectors are:

I’m forcing HDMI output because I’m using a HDMI -> DVI converter and so it seemed like a safe choice.

With dev tools open I can see that USER_PRESENCE is not being logged anywhere in the console.

I followed this post and ran:

“Run npm rebuild --runtime=electron --target=1.3.4 --disturl=https://atom.io/download/atom-shell --abi=49”
in the MMM-PIR-Sensor folder,

[jc21]

Sounds like you’re on top of that then.

Just fyi, the latest code for the original pir sensor module will rebuild the compiled dependencies for you as part of the npm install command in the module. There should be no reason to run npm rebuild manually unless you get those pesky “expected version xx but got xx” errors.

[open_book]

@jc21 just for closure here I found the issue. After running the python script again I realised that the PIR was always HIGH even with the sensitivty dialled right down.

So I checked the leads going into the pi and found that, despite checking it many times, I’d mixed up GND and VCC :(

The lesson for any other idiots out there when testing is, run this Python script and make sure that the PIR stops broadcasting “Motion Detected!” when you cover it with something:

from gpiozero import MotionSensor
import os

pir= MotionSensor(22) //the gpio pin PIR OUT is connected to
while True:
               if pir.motion_detected:
               print (“Motion Detected!”)

Code from this site

With some further adjustments for sensitivity it’s now working great!

[jc21]

Great stuff. People shouldn’t discount a faulty PIR either. The one I had on the shelf for ages wasn’t detecting quite right so I ordered another one and the difference in detection is huge. I’m not sure if these have a shelf life or what but yeah, that was my recent experience.

It’s equal if i have the original from @paviro or the modification.

Can anybody help me?
