Aqara U400 Replaces $249 Nest x Yale Lock, Adding UWB Unlock and Fingerprint Access

Summary
$269 Aqara U400 replaced a Nest x Yale lock in the author's Google-centered setup, with the switch described as a "game changer" after a few days of use.
UWB auto-unlock for iPhone, a built-in fingerprint reader, NFC card support and a mechanical key addressed features the older lock lacked, with fingerprint access serving as a quick fallback when UWB misses.
Matter setup links the lock to Google Home, Apple Home, Alexa and SmartThings, while auto-lock uses a gyroscope to detect door closure and can be delayed for short trips outside.
Two software updates arrived within weeks of installation, adding better battery reporting and tuning motor torque and Matter hub binding.
A rechargeable 4,880mAh battery and USB-C charging replace the Nest x Yale's four AA batteries, and the author argues the extra features justify the $20 premium over Google's $249 lock.
