The WiFi bridge completely failed outside the warranty period. It was spotty for a year with occasional disconnects/going offline and having to be reset and reconnected through the app. Now now matter what I do (press the button for 5 or 10 seconds) the light doesn't flash. I think it's a failure at the hardware level. August Support would not send a replacement and only offered 20%. I am considering taking out he August module out of my Yale lock and replacing it with Z-wave now.
