New page

Hello all,

I edited a script for shutting down on powerloss after x seconds.
For automatic shutdown, I call it with crontab.
The mod of the file has to be changed to 755 before. (chmod)

I hope this helps.

Greetings

Below the Script:

#!/usr/bin/env python3
#This python script is only suitable for UPS Shield X1200, X1201 and X1202

import gpiod
import time
from subprocess import call

PLD_PIN = 6
chip = gpiod.Chip('gpiochip4')
pld_line = chip.get_line(PLD_PIN)
pld_line.request(consumer="PLD", type=gpiod.LINE_REQ_DIR_IN)

try:
while True:
pld_state = pld_line.get_value()

if pld_state == 0:
print ("Powerloss detected")

time.sleep(10) # Change this to preferred value

pld_state = pld_line.get_value()

if pld_state == 1:
print ("Power ready")
pass
else:
print ("Shutting down")
time.sleep(1)
call("sudo nohup shutdown -h now", shell=True)

finally:
pld_line.release()
