I'm now on my 4th Kevo deadbolt and am using it with Kevo Plus.  The status of the lock has never displayed correctly despite the first 2 replacements.  The most recent problem was the lock unlocking randomly with no one around the lock or the app.  Twice it unlocked in the middle of the night.  Kwikset replaced it immediately, but my confidence remains low.  So far, the 3rd replacement is working and has not unlocked on its own.  The status of the lock still does not display correctly in the app.  All other functions work as expected including notifications from guest users.
