My Maestro did not want to perform on battery via Wi-Fi (in another room today). I think mainly the problem was a bad internet connection. It work better if I only used one panafall. I was surprised it had a bad connection while sitting at my operating position only inches away from the Wi-Fi. I've only been able to use it for about a month and I've only tried it remotely ( so to speak) one other time and it worked okay.
