testing wemo ouimeaux script to get the state of my belkin wemo device

switch.py

from ouimeaux.environment import Environment

def on_switch(switch):
        print ('********  Switch found:', switch.name)

def on_change(value):
        print('********  light has changed state and has been switched!')

env = Environment(switch_callback=on_switch, with_cache=False)

env.start()

env.discover(3)

lounge = env.get_switch('Lounge room lamp')

lounge.register_listener(on_change)

env.wait()

Above currently doesn't work. It finds the switch and if I run a different script I can turn it on and off, but I can't seem to get the above to tell me when the switch has been turned on or off! Trying to do something similar to the on_motion EVENT https://github.com/iancmcc/ouimeaux#id5

this is the output i get; so it is subscribing, but when I press the on/off button on the wemo it doesn't register this in the above script, have i missed something? please feel free to edit it!

('Switch found:', 'Lounge room lamp')
('Subscribing to basic events from , (WeMo Switch "Lounge room lamp",))

update.... just upgraded to 0.5.1 and it seems to of fixed my problem and is detecting the switch changes now ;)

but now it is coming up with this error....

'********  Switch found:', 'Lounge room lamp'
