I just added Kevo Plus and I have no idea how my phone is talking to the lock or if it is actually talking to the lock. The gateway currently says my door is locked when I can clearly see its not. History is hit-and-miss. When someone locks the door, I generally get a notification that the door is locked. However, I rarely get notifications of the door unlocking. I think its because the phone is switching from mobile data to WiFi but I cant imagine why it didnt occur to the product team that the message should be cached until it could be sent. How hard is that? Two more crappy experiences that should not exist for a smart phone and a smart lock: 1. The lock should have enough brains to keep a log of key fob unlocks and sync that with the owners phone when in range. 2. Removing a fob from the lock shouldnt require a complete clearing of the lock. Why do I need to re-add phones when I erase a fob? I love the idea. I love the concept. I get the feeling that someone dismantled the development team as soon as the product was released.
