Data from the official Aqara and Schlage sites.
2026 verdict
Walk-up ultra-wideband unlocking is the split: the Aqara Smart Lock U400 is the more complete smart lock against the Schlage Encode.
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.
