Aqara’s third headline device, the U400 Smart Lock, becomes the company’s first UWB-based lock enabling true hands-free unlocking via Apple’s Home Key on iPhone or Apple Watch, with proximity-based security to prevent unlocks when inside or merely passing by; it remains Matter-certified, runs over Thread, and is Aliro-ready, signaling broader digital key expansion across platforms.

The U400 integrates a 9-axis Multi-State Sensor P100 capable of AI-driven motion tracking to monitor door/window activity, object movements, vibrations, and potential security breaches across Zigbee and Matter-enabled networks.

Aqara unveiled its CES 2026 lineup at Booth 51229, Venetian Expo, highlighting spatial intelligence technologies designed to boost security, comfort, and convenience in various spaces.

The U400 features IP65 exterior durability for outdoor use and ships with a 4880 mAh rechargeable Li-ion battery offering up to six months between charges.

Design-wise, the U400 has a relatively bulky footprint with a sleek, non-retrofit look, available in black priced at $269.99, and the exterior keypad remains hidden when not in use.
