When it works it is great. I spent my the money to purchase the gateway to improve connectivity, I was wrong. I have been sitting about 4 feet away from the lock and 5 feet away from the gateway. The wireless router is about another 5 feet away from the gateway. I have Internet connection but keep getting the message no connectivity when I try to use the app to unlock the door. When I am next to it opening it manually I then notice the app updates and is now connected. I have never had much of a problem getting in from the outside. A few times I had to get the phone out and place it next to the lock for it to work.
