The new Aqara Smart Lock just redefined life at CES 2026

CES 2026 is making one thing clear: the smart home is moving past voice commands and endless apps toward spaces that live with you. Aqara arrived this year with the idea that spatial intelligence is the future of connected living.

Known for its reliable sensors and thoughtfully designed smart home gear, Aqara is now building an ecosystem powered by multi-dimensional sensing and AI. The headline moment? The new Aqara Smart Lock U400, a first-of-its-kind lock that uses Ultra-Wideband (UWB) technology with Apple Home Key to understand user intent.

A previous model of the Aqara Smart Lock earned our Editors’ Choice badge, so we were so excited to see all of these new improvements—this year’s 2026 CES launch might be its most impressive yet!

The Aqara Smart Lock U400 can almost read your mind

Every smart lock promises convenience, but anyone who’s tried one can tell you that’s not always the case. Electronic keys don’t allow you to be hands-free, app access is frustrating when networks are slow, and face recognition may unlock your doors when you don’t mean to.

While we named the Aqara Smart Lock U200 the best overall smart lock in our testing, it doesn’t have all of the newest features unveiled at this year’s CES.

Aqara’s Smart Lock U400 is the first to remove these barriers and answer them with a different kind of technology. Ultra-Wideband (UWB) combined with home key in Apple Wallet, a first-to-market pairing for smart locks, allows the device to track your trajectory and proximity, so it can tell the difference between you approaching your front door and just walking past it to grab something from the car.

In real life, that matters. You don’t have to fumble for keys, pull out your phone, or worry that your door accidentally unlocks on your way out of the house.

The Smart Lock U400 is also Matter-certified, meaning it integrates seamlessly across Apple Home, Google Home, Alexa, SmartThings, and Home Assistant. It’s Aliro-ready, too, ensuring secure, consistent access across devices and operating systems.

Aqara’s expanding spatial intelligence ecosystem

The Smart Lock U400 may be the star, but it’s part of a much bigger story that Aqara is telling at CES 2026—one centered on spatial intelligence. This means that gadgets don’t just exist in your space; they learn, adapt, and anticipate your needs and preferences over time.

Here are a few other Aqara gadgets that we loved hearing about:

• Spatial Multi-Sensor FP400: The FP400 can tell how many people are present, where they’re located, and whether they’re sitting, standing, or lying down. That means lights that turn on only in occupied zones, climate control that adjusts based on where people actually are, and safety alerts if someone falls and doesn’t get back up.

• Multi-State Sensor P100: This sensor turns everyday actions into smart triggers. Opening a window can pause the HVAC. A mailbox drop can trigger a notification. A cabinet opening can activate under-cabinet lighting.

• Thermostat Hub W200: Instead of relying on schedules, the W200 adjusts temperature based on real life. It can tell when household members are home, asleep, or on the way back—cooling down at night, saving energy when no one’s home, and preheating or precooling before arrival.

• Camera Hub G350: Designed for homes that use multiple platforms, the G350 lets you check in, talk, and receive alerts across ecosystems without juggling extra apps.

Why the Aqara Smart Lock U400 is the product to watch

Of everything Aqara is showing at CES 2026, the Aqara Smart Lock U400 is the clearest expression of its vision. It brings intent-aware access, seamless automation, and broad interoperability together in a way that homeowners can feel every single day.
