I have tried everything to get auto unlock to work reliably, including exchanging the lock, and nothing has changed. Auto Unlock does not work at all, but the lock sometimes unlocks by itself in the middle of the night when I am home. This is quite disconcerting! It does not seem that this lock should continue to be sold if it cannot function reliably. After all, a lock is designed to prevent unauthorized access to the premises and grant access when needed. Many users are still complaining about auto unlock not working, despite multiple updates. Although The Wyze “Wizards” are pleasant enough when speaking on the phone, they are not really helpful. Wyze is a great company, and I love supporting their products, but this lock just does not work as it should.
