Smart locks have gotten progressively more convenient, adding features like fingerprint sensors, palm vein readers, and more app-based controls. These are all well and good, but there's one problem with them -- they all still require you to actively do something. The Aqara Smart Lock U400 changes that equation with ultra-wideband (UWB) support for Apple Home Key, allowing the lock to detect your approach and unlock automatically just by knowing it's you.
