It's not what you'd call a complete thought, but Kwikset's Kevo smart lock introduces some unique ideas into the smart lock ecosystem.
The folks at Kwikset have been trying to make locks and deadbolts smarter for a while now, and as a result their products are usually considered some of the best for people looking to add some smarts to their home. Their latest smart lock, the Kevo deadbolt, is an attempt to take what they've learned so far and make the act of locking and unlocking the door more natural. You basically make your smartphone the key, and assuming you keep that key in your pocket you need only reach out and touch the lock when walking up to the door to unlock it. It's simple, reasonably user-friendly, and Kwikset's software for Kevo extends this functionality in a was that makes a lot of sense.
To accomplish this, Kwikset basically walked away from all of the things that made their existing smart locks functional and user-friendly.
This, as well as some painfully absent device support, is where things start to go wrong.
