The Aqara U400 smart lock, which features Apple's U1 ultra-wideband chip for hands-free unlocking, is now available at a discounted price of $229.49, down from its original price of $269.99, during Amazon's Big Spring Sale. This smart lock is particularly notable for iPhone owners, as it integrates seamlessly with Apple's Home Key, allowing for reliable and convenient unlocking without the need for an extra app. According to Jennifer Pattison Tuohy, who reviewed the U400, this implementation of hands-free unlocking is the most reliable she has tried yet. The U400 also offers other unlocking options, including a touchscreen keypad, fingerprint recognition, and a traditional key. Additionally, it is a Matter-over-Thread lock, which means it can work with various smart home ecosystems, and it requires a Thread border router, such as a recent Apple TV model or a HomePod, to enable communication over Thread.
When Jennifer Pattison Tuohy says the Aqara U400's hands-free unlocking is the most reliable implementation she's tried, that means Apple's U1 ultra-wideband chip is a game-changer for smart lock technology. This development has significant implications for the future of smart home security, as it provides a seamless and convenient unlocking experience. The fact that the U400 is now more affordable during Amazon's Big Spring Sale makes it an even more attractive option for those looking to upgrade their smart home setup. As the smart lock market continues to evolve, the integration of ultra-wideband technology is likely to become a key differentiator for top-tier smart locks like the Aqara U400.
