Why UWB Makes the Aqara U400 the Smart Lock to Beat

Aqara’s U400 smart lock uses UWB to unlock automatically when a paired device is nearby, enabling hands-free entry.

It also offers fingerprint, keypad, and spare-key access for backup and flexibility.

The lock works with major smart home ecosystems, including Apple Home, Google Home, Alexa, SmartThings, Matter, and Thread.

Built for everyday use, it includes USB-C rechargeable power, auto-locking, and IP65 weather resistance.
