or

import blus

class Observer(blus.DeviceObserver):

    def seen(self, manager, path, device):
        alias = device.get("Alias")
        print("Seeing %s at %s" % (alias, path))

        # device = blus.proxy_for(device)
        # device.Pair()
        # device.Connect()
        # etc ...

blus.DeviceManager(Observer()).scan()
