Deal Details
The Aqara Smart Lock U400 is a deadbolt-replacement smart lock that features Ultra-Wideband (UWB) technology. This allows for true hands-free auto-unlocking as you approach the door. It is highly integrated into the Apple Home ecosystem (supporting Apple Home Key) and operates via Matter over Thread for multi-platform smart home compatibility.

Key Features & Capabilities
* Hands-Free UWB Entry: The lock measures the precise radio pulse distance to your iPhone or Apple Watch. It safely unlocks as you walk up to the door without requiring codes or biometrics. Its spatial accuracy ensures it won't unlock if you are just walking around inside the house.
* Plentiful Unlocking Methods: Beyond UWB, you can open the door using the integrated 0.3-second fingerprint scanner, a hidden touchscreen keypad, Apple Home Key NFC tap, emergency physical keys, or the mobile app.
* Smart Home Connectivity: Built natively on Matter over Thread, it works seamlessly with Apple Home, Google Home, Amazon Alexa, and Samsung SmartThings. It is also one of the first Aliro-certified locks designed to standardise UWB access across iOS and Android ecosystems.
* Power and Build: It uses a rechargeable and removable lithium battery that lasts roughly 6 months on a charge. It includes an integrated gyro sensor for auto-locking when the door closes and carries an IP65 weather-resistance rating.

yes, during prime day - but per the C*mel site, it's a good price. usually $269.99 and has only dropped VERY briefly below this price. If you were already wanting this lock - as I happened to be - this is a deal worth jumping on and not talking trash on just because it has been this price before for brief moments in history.

See the chart for yourself (I don't think we're supposed to link it here)
