I have two questions. Since I did the Smart lock software update about a week ago I have noticed that it will not unlock when I turn the alarm off in the morning. It locks when I put the system in "home" mode at bedtime but in the morning it will not open on its own. I have deleted and re-installed the lock twice and still no change. Secondly I am unable to sync/pair the sensor that is on the door that has the Smart Lock.
