Is it possible to make a connection to a certain Wi Fi network as a condition?

[CAP33]

Is it possible to do so?
if <Connecting to a specific wifi network>:
Action

Try:

Code: Select all

#!/usr/bin/env python

import subprocess

try:
  ssid =  subprocess.check_output(["iwgetid", "-r"]).rstrip()
except subprocess.CalledProcessError:
  ssid = ""

if ssid == "mySSID" :
  ActionHere

Try:

Code: Select all

#!/usr/bin/env python
import subprocess
try:
  ssid =  subprocess.check_output(["iwgetid", "-r"]).rstrip()
except subprocess.CalledProcessError:
  ssid = ""
if ssid == "mySSID" :
  ActionHere
  

Code: Select all

#!/usr/bin/env python

import subprocess
from time import sleep

try:
  ssid =  subprocess.check_output(["iwgetid", "-r"]).rstrip()
except subprocess.CalledProcessError:
  ssid = ""

while True:
  if ssid == "MySSID" :
      print("Connect")
  else:
      print("No connect")
  sleep(1)

Unfortunately, it does not work. Writes "No connect".

Did you put the name of your SSID in to the following line?

Code: Select all

if ssid == "MySSID"

You can of course add

Code: Select all

print(ssid)

to your code to see what wifi network is detected.

Yes, I put the name of my SSID in to the following line

Code: Select all

if ssid == "MySSID"

I added a line

Code: Select all

print(ssid)

and noticed that a string is output b'bn98'.
bn98 it my ssid, but what is b?

[scotty101]

b indicates that it is a python 3 "byte literal".

Try the following instead of the current if.

Code: Select all

if ssid.decode('ascii') == 'bn98':

This decodes the "bytes literal" to a standard python string.

Many thanks!
