Here is a smart door lock that offers tighter integration with Apple HomeKit. The Schlage Encode Plus Smart WiFi Deadbolt supports Home Keys, so you can easily open your door with a tap on your phone or smartwatch. It also lets you create and manage up to 100 access codes (recurring, temporary, or permanent).
This smart deadbolt combines with your phone to maintain a real-time activity log. It plays well with Amazon Alexa and Google Assistant. With Power Reserve, users may still be able to tap to unlock up to five hours after their phone battery runs out. Expected to become available late this spring. More information can be found here.
