Enso Connect has a 3 tier fail system and 2 ways for the guest to access the smart lock. If the code fails, the guest can tap a button in the Boarding Pass and automatically request a new code. If this code fails, we provide a new code. On the third try, we provide a permanently available code that we know already works, and delete it after their stay. The guest can also tap the lock or unlock buttons without entering the code to access the property remotely. If all fails, we send you a notification for manual resolution. This notification can be sent via SMS, Email, or as a notification in our mobile app.
