i guess i have the same issue.
you can try easily with this module

https://github.com/bugsounet/MMM-NewPIR

you can change inside the module the mode

mode: 1 - use vgencmd
mode: 3 - use tvservice

in my case it works. But i think i have an adjustment problem.

The screen turns off and also the sensor can wake up the screen again.
But if there is no movement, the screen turn on randomly. Currently i have no solution. I guess there is some wrong settings on sensors Potentiometer.

@sdetweil
Hi sdetweil, this was a good hint. I think the problem are the adjustments of the sensor itselfs. the time values in my previous post changed now. But the problem still exists.

The reason why the screen wake up without movement is, the overlapping of signals. there is one delay in the script, but also one of the Sensor. If the script turns off the screen and the sensor gives also a signal regarding the time delay a little later, the screen will turn on again. so my opinion.

But what is now the best adjustment of it?
is it possible to inactivate the time delay of the sensor itself?

In what position is the jumper to be set?
sensivity of it should be clear. thats a customized value for the different situations.

@sdetweil thx for your comment.

I guess the sensor works.
If i start this script, the sensor switch after 2 minutes off.
If the sensor receives movements, the screen turn on, so i think it works. But i will test your script in the evening.

If there is no movement registered from the sensor the screen switch on after 1 minute.

I don’t understand why the countdown is 2 min? In the script the delay time is setted by 10 sec.

And why the screen turns on after another one minute. If there is no signal from the sensor??

@dbg i’m using Raspberry Pi 3 Modell B Plus (B +)

I have no idea whats wrong.
I can change the delay time value randomly. There is no effect. After exact 2 minutes the screen turn off.

Could it be, there is something activated in the tvservice?

hi.
There are some news about my Sensor problem.

i tried to install these steps according this link

https://teilzeitrebell.de/blog/magicmirror-part-2-bewegungsmelder

i made two sh-scripts for screen on & off

monitor_off.sh
monitor_on.sh

then i created this phyton

pir_loop.py

!/usr/bin/env python

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

io.setmode(io.BCM)
SHUTOFF_DELAY = 10  # seconds
PIR_PIN = 17        # Pin 11 on the board

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

    while True:
        if io.input(PIR_PIN):
            last_motion_time = time.time()
            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()
        time.sleep(.1)

def turn_on():
    subprocess.call("sh /home/pi/Pir-Sensor/monitor_on.sh", shell=True)

def turn_off():
    subprocess.call("sh /home/pi/Pir-Sensor/monitor_off.sh", shell=True)

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

i can start this with

python pir_loop.py

and it seems that it works.

But in the code i defined a delay of 10 seconds. But after it, it happend nothing.
the weird thing is, that the screen turn off after exact 2 minutes. If i move in front of the sensor the screen turn on again.
But if i do nothing or cover the sensor with something the screen turn on after exact one minute.

does anybody has an idea, whats wrong there?

Thx. now the table should be clear.
But the PIR doesn’t work.
After delay the screen switch off.
But i can breakdance in front of the sensor. It happend nothing…

but if i remove the cable from sensorpin 23 the sceen wakes up.

Hi guys,

i want to install for my Magicmirror project a PIR Sensor (HC-SR501) for switching the monitor automatically on/off.

i have already tested MMM-PIR-Sensor and MMM-PIR. But both have the same issue.

After the adjusted delay the monitor switches off. But there is no chance to wake it up again.

It seems to me that i have installed something wrong in the pins.
In both modules i need a value for sensorPin:
That mean the "out"wire of the PIR? thats right. That mean according my Occupancy i have to put “16” into it?

please help!

hey guys,
sorry for this stupid question but i’m on the beginning to set up a magic mirror.

i want to realize two calendars side by side.
i guess i have to add two times the calendar module? i tried this but it doesen’t work.
does anybody has an example code for a case like this?

Thanks in advance
Markus
