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()

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'
