Aqara Smart Lock U400, with M100 Hub, 2 Batteries, and Hands-Free Unlock

Features:

Hands-Free, Instant Unlock-Still struggling to find your keys or pull out your phone? UWB frees your hands. Whether you're carrying heavy bags in the rain or holding your child, you can walk right in effortlessly. Powered by Ultra-Wideband (UWB) technology, it achieves centimeter-level precision by measuring Time of Flight (TOF) and Angle of Arrival (AOA), ensuring seamless and secure access.
Smart Intent Recognition-UWB technology helps track your movement trajectory, speed, and direction. The door unlocks only when you approach the lock in a stable, intentional path. Simply passing by or lingering near the door won’t trigger an unlock.
One-Way Unlock Protection – No Accidental Unlocking from Indoors. Worried that your child might accidentally unlock the door while playing with a phone in the living room? No worries. The smart lock detects when you’re inside and prevents unintended unlocking. Its precise positioning system ensures security for you and your family.
One-Tap Sharing for a Seamless "Hands-Free Unlock" Experience – Enjoy Cutting-Edge Tech as a Family-Easily share door lock access via Apple Home family group. Your family and friends don’t need to register an account or pair any devices—once they accept the invitation, their UWB unlocking capability is automatically synced.
Unlock Your Door Like Unlocking Your Phone-Equipped with a 160×160 resolution fingerprint module, featuring a sensor area 75% larger than popular solutions on the market. This ensures higher sensitivity, eliminating unresponsive issues and delivering a stable and reliable unlocking experience.
