Aqara U300 Smart Lock Upgraded Version: Supports Apple Home Key via Thread
For families with busy schedules, the Aqara Smart Lock U300 turns your front door into a seamless entry point. Imagine coming home with arms full of groceries—just tap your iPhone or Apple Watch, and the lock opens instantly. No fumbling for keys or codes. The high-resolution fingerprint sensor (double the size of common sensors) recognizes you in under 0.3 seconds, so even kids with small or wet fingers can get in without delay.
What sets this lock apart is how it bridges your smart home ecosystems. With Matter over Thread, it works simultaneously with Apple Home, Alexa, and Google—no need to choose. Set auto-lock timing so you never worry if you locked the door after leaving. The lock runs up to 10 months on four AA batteries, and dual USB-C ports provide emergency backup power. All your data stays encrypted and local, not in the cloud. Whether you're unlocking with Siri, a code, or a fingerprint, the U300 makes every entry feel effortless and secure.
