[How to do instruction] Use hardware momentary switches to control moOde

[sisim]

I added your lines, it looks like this now:

Code:

# Main
while True:
   time.sleep(1)

def sw_1_event(channel):
          subprocess.call(sw_1_cmd)
          print('Executed: ' + sw_1_cmd)

But I still don't see anything happening when I press any button
