My bad, for giggles, I unplugged my router, the light on the hub turned red, but I was still able to control my devices with the smart remote.  I didn't try it with my iPod Touch, since my wife was out walking with it, so I am not sure if the iPod wold be able to contol it since it does need to be connected to the same Wi-Fi network to work, I am guessing no in that regards.
