I purchased this 8 months ago and the lock worked great for the first 7 months. After putting in the new battery and updating the settings (the lock reverted to default settings after the batteries were changed), the lock has been having issues with the coming home unlock feature. The lock will unlock when I come home, but immediately lock itself after a few seconds (not stay unlocked until the door is opened and shut again, or wait the amount of time set to relock). When I access the app to unlock the door after this happens, the lock will immediately lock itself while the door is open, or fail to sense that the door has closed, and will not lock itself, nor show that the lock was locked manually, and notify me that the door is open. Otherwise, with full app and manual control, the lock still works as intended.
