Some locks integrate with other connected home devices, such as smoke alarms, and services, such as Amazon Alexa, Apple HomeKit, Google Assistant, IFTTT, and Matter. IFTTT is what lets you, for example, configure your doors to unlock when a smoke or carbon monoxide alarm goes off or set your smart lights to turn on when someone unlocks the door. Depending on your home automation setup, you can even pair your lock with a video doorbell so you can see who is at the door before you unlock it. You might also configure an indoor security camera to begin recording when someone unlocks the door.
