Thread, Matter, HomeKit and Home Assistant sit next to fingerprint, keypad, NFC, Apple Home Key and a USB-C emergency port, plus one-time, periodic and anti-peep passwords. The Schlage Encode is the more affordable, better-reviewed Wi-Fi deadbolt with a built-in keypad and no extra hub for Alexa or Google. Google Home and Alexa on the U400 need an Aqara Hub. Pick the Aqara Smart Lock U400 for hands-free HomeKit entry; pick the Schlage Encode for a simple US deadbolt that talks Wi-Fi on its own.
