I have had my smart lock for a year, it was great the first few months.  Now it only works half the time, I have to repair connection over and over.  Sometimes the lock decides it is time for a software update when you go to connect and you have to stay in the proximity of your lock for 5-10 minutes... just enough to make you late!  Guys, make it update when you UNLOCK and arrive home, not when you connect to lock up!
