Aqara Smart Lock U400 - The Quiet Threshold
Aqara · $$
Aqara Smart Lock U400 brings a quiet hand to the front door. UWB can open the lock as an authorized iPhone or Apple Watch approaches, but that feature needs a compatible device and a Thread-enabled Apple home hub. Matter over Thread connects it to Apple Home, Home Assistant, Google Home, Alexa, and SmartThings through the right controller. A fingerprint reader stores up to 50 fingerprints and is rated for recognition in 0.3 seconds, with recognition accuracy up to 98.6 percent. The rechargeable battery is rated for up to six months per charge. The outer panel is IP65 weatherproof, and a built-in gyroscope can engage auto-lock when the door closes.
