For the future u can put in your code here: https://jshint.com

Just to analyze what maybe went wrong

Blau und schwarz beschreibt nur die Farbe des Streifens selber (nicht der LED). Also für die Funktion egal.

Naja, also die Temperaturen kommen von meinem IoBroker Server. Um ehrlich zu sein habe ich schon länger nicht mehr an meinem Spiegel gearbeitet, sondern andere Projekte gestartet und vollendet.
Mein ganzes Haus ist mittlerweile steuerbar (Licht, Thermostate, Lautsprecher etc…). Unter anderem habe ich eben auch Temperatursensoren von Xiaomi im Einsatz, die ihre Werte an meinen Server schicken.
Auf dem Spiegel zeige ich die Werte dann mit dem MMM-iobroker Modul an.

Aber ich habe auch viel mit ESP’s gemacht. Habe derzeit ca. 8 Stück im Einsatz. Einer steuert meine komplette Heizung. Einer steuert meine Klingel. Einer wertet meine Alarmanlage aus. Zwei sind für meinen Infinity Tisch… etc. pp… ^^
Macht ziemlich viel Spaß

Blue and black only describes the color of the strip itself (not the LED). So no matter for the function.

Well, so the temperatures come from my IoBroker server. To be honest, I have not worked on my mirror for some time, but started and completed other projects.
My whole house is now controllable (lights, thermostats, speakers etc …). Among other things, I have also used temperature sensors from Xiaomi, which send their values to my server.
On the mirror I then display the values with the [MMM-iobroker] (https://github.com/ioBroker/MMM-ioBroker) module.

But I also did a lot of ESP’s. Currently have about 8 pieces in use. One controls my entire heater. One controls my bell. One evaluates my alarm system. Two are for my infinity table … etc. pp … ^^
It’s a lot of fun

I have got this one. 5m with 60 LEDs per meter for about 17€

Well, if i had to do that project gain, i would not choose the RGB-5050 stripes again…

I would directly get WS2812, because u just need one PWM Pin and with that you were able to do things like animations…

In another project (infinity table) i choosed this one and was pretty amused

https://youtu.be/IcDjzh03W-4

LED-Pin just shows, if the PIR detects motion. You don’t need to use it.

The pir.py script starts the other shell scripts when motion is detected.

So all commands for the RGB-Stripe are within the shell scripts (monitor_on / off.sh).
And as u can see, i used GPIO 17,22 and 24.
17 = red
22 = green
24 = blue

To control the LEDs i used PIGPIOD and it’s commands, as i wrote.

So after installing PIGIOD u can start it with:
sudo pigpiod

Commands like pigs p 22 128 will set green to 50%.
pigs p 24 255 will set blue to 100%

in the shell script i fade all colors from 1 to 12% with sleeps.

Edit:

As i wrote before u need to Autostart pigpiod via rc.local.

sudo nano /etc/rc.local

Mine looks like this:

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

# Print the IP address
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
  printf "My IP address is %s\n" "$_IP"
fi

iwconfig wlan0 power off &

sleep 5 &

/usr/local/bin/pigpiod

sleep 10 &

/usr/bin/python /home/pi/pir.py &

exit 0

Well, meanwhile i changed my background, but still love it

Hey @metalldetector

I already did somewhere in the forum ^^

You need to install PIGPIOD.

sudo apt-get install build-essential python-dev unzip wget

wget http://abyz.me.uk/rpi/pigpio/pigpio.zip && unzip pigpio.zip && cd PIGPIO && sudo make install

Connect the PIR like shown at Part 2.2 and follow the guide:
https://forum.magicmirror.builders/topic/6291/howto-turn-on-off-your-monitor-time-based-pir-button-app?page=1

When creating the pir.py and fill ist with this code:

#!/usr/bin/env python

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

io.setmode(io.BCM)
SHUTOFF_DELAY = 119 # seconds
PIR_PIN = 25       # 22 on the board
LED_PIN = 16

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/monitor_on.sh", shell=True)

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

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

For the monitor_on.sh use this:

Hope that helps. Try to find your best way and ask, if u need more help

Edit:
Oh and u need to start Pigpio on reboot with rc.local.

@chandra said in {HowTo} turn on/off your monitor (Time based, PIR/Button, App):

Screen goes off after 120sec, But when it sense the motion, the screen is black.

Hint from the main post:

To check if it works just go into terminal via ssh and type:

sudo tvservice -o to turn off
sudo tvservice -p to turn on

edit: for some monitors the following commands work better. Please use them if your monitor needs it:

vcgencmd display_power 0 to turn off
vcgencmd display_power 1 to turn on

edit:
also check this:
https://forum.magicmirror.builders/topic/6291/howto-turn-on-off-your-monitor-time-based-pir-button-app/11

There is no mistake as far as i can see.

The “&” just need to be written, when a second or third command follows.

So when u are just using this one command both (with or without the “&”) should work

I am glad, you got it

As you can see i used PIN 25 for the PIR and 17,22,24 for the LED’s.

Keep in mind, that the physical GPIO Number isn’t the same as with BCM numbering !!! Thats important!

In the script (line 9) u can see that it uses the BCM Numbering. That means the following:

BCM pin 17 = physical PIN 11
BCM pin 22 = physical PIN 15
BCM pin 24 = physical PIN 18
BCM pin 25 = physical PIN 22

So the LED’s must be connected with physical PIN 11,15,18 and the PIR on PIN 22.

Hope that was clear ^^
My english isn’t very well.
