The bluetooth part of it pretty much never works, even when standing right next to the lock with my phone.  In the settings it says bluetooth connection is weak, when my phone can reach a speaker over bluetooth from 50 ft away.  When I arrive home, maybe 1 time out of 100 does the door auto unlock.  If i open the app to open the door even while I am standing at the door and both my phone and the lock have strong wifi, it still takes like 5 or 6 minutes to connect. This thing is garbage!!!
