I saw this interesting idea from Kalle Hallden’s video. It is about alerting you when someone’s IP connects to the network
import sys
import subprocess
import os
from decouple import config
IP_NETWORK = config('IP_NETWORK')
IP_DEVICE = config('IP_DEVICE')
proc = subprocess.Popen(["ping", IP_NETWORK],stdout=subprocess.PIPE)
while True:
line = proc.stdout.readline()
if not line:
break
#the real code does filtering here
connected_ip = line.decode('utf-8').split()[3]
if connected_ip == IP_DEVICE:
subprocess.Popen(["say", "Linnea just connected to the network"])
Error
Traceback (most recent call last):

Press any key to continue . . .
Seems like you forgot to setup a settings.ini. It should look something like this:
[settings]
IP_Network=YOUR NETWORK IP
IP_DEVICE=YOUR DEVICE IP
