MMM-PIR-SENSOR not working

[mab6435]

I just got my mirror up and running and was trying to install the PIR sensor module provided by @paviro (https://github.com/paviro/MMM-PIR-Sensor) but it doesn’t seem to be working. I followed the step by step instructions as written and still the screen does not turn off.

My modification to the modules config file looks like this.
{
module: “MMM-PIR-Sensor”,
}
I also ran the command /opt/vc/bin/tvservice -s and receive the output state 0x12000a [HDMI CEA (16) RGB lim 16:9], 1920x1080 @ 60.00Hz, progressive

I created a short python script to test if the sensor works and it does. But for some reason when I start up MagicMirror (using npm start) my webpage display shows up but the screen or display never turns off.

Anyone able to help?

Bur that is not like it is described in the readme of the module.

try:

{
			module: 'MMM-PIR-Sensor',
			config: {
			sensorPIN: 22,
			powerSavingDelay: 120 // in seconds
			}
		},

Also u need to use a powersaving delay. Cause the default is 0 !

And i am not sure, but i think u used “ instead of "

@cruunnerr

That happens when users don’t use a code block to paste their code. Quotes get screwed up.

OH nice so now we’re deleting messages…Thanks appreciate that…

Hi guys, thanks for the help. Unfortunately that did not fix the issue…
I changed the code like you mentioned. Does anyone have any idea why the monitor never turns off. Googling the topic it seems other people have had a similar issue but no solutions ever been found.

Its very strange to me because with a python script I have it printing out when it detects motion and when it detects none and it works flawlessly. I have a feeling that for some reason the MMM-PIR-SENSOR isn’t actually connecting with the rest of my magic mirror when I start things up. Below is my entire config.js file.

modules: [

	{
		module: "clock",
		position: "top_left"
	},
	{
		module: "compliments",
		position: "lower_center"
	},
	{
		module: 'MMM-PIR-SENSOR',
		config: {
		sensorPIN: 22,
		powerSavingDelay: 120 // in seconds 
		}
	},
	{
		module: "newsfeed",
		position: "bottom_bar",
		config: {
			feeds: [
				{
					title: "New York Times",
					url: "http://www.nytimes.com/services/xml/rss/nyt/HomePage.xml"
				}
			],
			showSourceTitle: true,
			showPublishDate: true
		}

	},
            {
                    module: "MMM-NFL",
                    position: "bottom_left",                              
            },
]

};

are u sure, u are using the correct pin?
The Module uses BCM numbering, so if u write in your config to use 22, it is physically 15, and this is GPIO 3!

type in console, while u are running through the PIR:

gpio read 3

before detecting it must give out a “0”. WHILE moving through the PIR it must give out a “1”

or simply type gpio readall before and while the PIR detects to compare results and see what Pin you are really using.

and please check if pm2 gives errors with pm2 logs

We all are here for some fun. But mentioning “dynamite” several times doesn’t help the user and it does not make your joke better.

[mab6435]

@cruunnerr I’m using the correct pin. I made a python script shown below:

from gpiozero import MotionSensor
pir = MotionSensor(22)
while True:
if pir.motion_detected:
print(“motion detected”)
else:
print(“NOTHING”)

With this it will print nothing until i wave my hand in front of it then motion detected until i stop. So I know for a fact the PIR sensor is connected and working properly. Also there are no errors when I start magic mirror the only thing that is mentioned about MMM-PIR-Sensor is it says no helper found for module: MMM-PIR-SENSOR. Anyone have any idea

[cruunnerr]

have u tried to delete the Pir Folder in your modules direction and start a simple new installation of the module?

or just go into the MMM-PIR-Sensor folder and type npm install again?

[mab6435]

@cruunnerr I just deleted the entire module and downloaded it again, following the instructions directly from the page.

To summarize, I know the sensor is working properly and connected to the right pin listed in the config file. I know nothing is wrong with the module i just downloaded it from github. I’ve posted the exact copy of my config file, no one seems to have a problem with that. What else could it be? For some reason the monitor wont shut off.

Its a Benq monitor connected to the raspberry pi via an hdmi cord.
Im not sure if this helps but when i type /opt/vc/bin/tvservice -s:
state 0x12000a [HDMI CEA (16) RGB lim 16:9], 1920x1080 @ 60.00Hz, progressive

[cruunnerr]

i can switch off and on my display by simply typing sudo tvservice -o and sudo tvservice -p

why are you using a MM module?
This is not related to the mirror itself. Use @cowboysdude (how funny is that in this context ;) ) script.
You can find it in his github respository. By the way, this dude creates really cool stuff, so its worth to have a closer look to it.

If your PIR is cabled well, it should work easily.

mba , I had the same issue but only because you have to force one detection, just the first time after you start magic mirror software. Then everything should be ok and working. So, after magic mirror is up and running, try to pass an hand in front of the sensor, then wait to see if it will turn off.

I had the same problems and I dont know why. So I searched for another solution. Now it works perfect.
I wrote one bash script for the power off and one for the power on.

Script Power on:
vcgencmd display_power 1

Script Power off:
vcgencmd display_power 0

than I used this Pyhton for the PIR

#!/usr/bin/env python

import sys
import time
import RPi.GPIO as io
import subprocess

io.setmode(io.BCM)
SHUTOFF_DELAY = 300  # seconds
PIR_PIN = 25        # 22 on the board
LED_PIN = 16        # 36 on the board

def main():
    io.setup(PIR_PIN, io.IN)
    io.setup(LED_PIN, io.OUT)
    turned_off = False
    last_motion_time = time.time()

    while True:
        if io.input(PIR_PIN):
            last_motion_time = time.time()
            io.output(LED_PIN, io.LOW)
            print ".",
            sys.stdout.flush()
            if turned_off:
                turned_off = False
                turn_on()
        else:
            if not turned_off and time.time() > (last_motion_time + 
                                                 SHUTOFF_DELAY):
                turned_off = True
                turn_off()
            if not turned_off and time.time() > (last_motion_time + 1):
                io.output(LED_PIN, io.HIGH)
        time.sleep(.1)

def turn_on():
    subprocess.call("sh /home/pi/MagicMirror/pir/monitor_on.sh", shell=True)

def turn_off():
    subprocess.call("sh /home/pi/MagicMirror/pir/monitor_off.sh", shell=True)

if __name__ == '__main__':
    try:
        main()
    except KeyboardInterrupt:
        io.cleanup()

I tryed to upload but not enough privileges

@sek_is_back hi know this is old but where do you save the scripts to, to make them function?
