Device_tracker ping on windows not working? (SOLVED)

Configuration
3

OMG! Resolved IT!

in ping.py

if sys.platform == ‘win32’:
self._ping_cmd = [‘ping’, ‘-n 1’, ‘-w’, ‘1000’, self.ip_address]

changed on:
if sys.platform == ‘win32’:
self._ping_cmd = [‘ping’, ‘-n’,‘1’, ‘-w’, ‘1000’, self.ip_address]

and all working! thx
