MMM-PIR-Sensor with RelayPin and execute script

[nogE]

Hi,
My goal is: PIR Sensor detect presence and switch the relay pin. Additionally it should execute ah script hue_on.sh to switch MirrorLight on.
Scripts works fine form CLI
In which position of the node_helper.js from MMM-PIR-Sensor Module i put the lines
exec(“/home/pi/scripts/hue_on.sh”, null);
exec(“/home/pi/scripts/hue_off.sh”, null);

pls help
thx

I have build in this python script in tho rc.local

import RPi.GPIO as GPIO
import time


#Board Mode: Angabe der Pin-Nummer
GPIO.setmode(GPIO.BOARD)

#GPIO Pin definieren fuer den Dateneingang vom Sensor
PIR_GPIO = 13
Relay_GPIO = 37
GPIO.setup(PIR_GPIO, GPIO.IN)
GPIO.setup(Relay_GPIO, GPIO.OUT)
GPIO.output(Relay_GPIO, True)
GPIO.setup(32,GPIO.IN)

read=0
wait=0
ein=0
button=1

while True :
   #PIR auslesen
   read = GPIO.input(PIR_GPIO)
   button = GPIO.input(32)

   if ((read==1 or button==0) and wait==0):
     GPIO.output(Relay_GPIO, False)
     wait=1
     ein=1
     time.sleep(0.5)
   elif ein==1 and button==0:
     ein=0
     time.sleep(0.5)

Hi Blackmirror,
thx for helping, i am no coders.
pls can you explain me, howto it works to start with your script my hue_on.sh and hue.off.sh scripts?

best regards
Egon

Sorry i understand. MMM-PIR-Sensor config with no RelayPin config. Make RelayPin with your script.

The MMM-PIR-Sensor module have not work at me.

So i make a new datei this the name PIR.py in my home - ordner.
And add python PIR.py in the rc.local
After this was switch the PIR on the GPIO-Pin 13 the relay-pin 37. Add pin 32 i have a button to open the relay manual.

when execute the python script (python /home/pi/scripts/light.py), i got following error:

File “/home/pi/scripts/light.py”, line 22
read = GPIO.input(PIR_GPIO)

Hi,

i got an error when i run python script. now the whole error message:

File “/home/pi/scripts/light.py”, line 22
read = GPIO.input(PIR_GPIO)

Python is a bit tricky. Unlike other languages python needs proper indentation. Make sure you don’t mix up tabs and whitespaces. Best practice is to use 4 whitespaces instead of one tab.

[Blackmirror]

Yes, the error code says, you have not enought whitespaces before the lines.
