Funciona muy bien

Auto lock when the door closes is unreliable. A third of the time doesn’t lock so have to be always on the lookout if door lock is triggered or not. Other than that it’s been good.

Works well with HomeKit via an AppleTV (acting as the Home hub). No issues with extreme rain, direct sunlight, and winter weather (the lock is fully exposed). Some issues noted in previous reviews are (sorry to say) user error. It's not super easy to set up: the lock needs to be set up using Bluetooth, which is fine because you do it once, or if you need to change a setting. There are lots of options to change in the app settings, but once you set it up in HomeKit, you can do the rest from Apple's Home app (or whatever home app you want). Where it gets confusing (maybe?) is setting up top automations. For example, we have two doors in a row, and the first lock and one tell the other to unlock to save tapping twice. I also had a light turn on automatically, but turning the light on/off triggered the door to unlock! The deadbolt hardware does seem "loose" compared to the old locks, but the deadbolt is super smooth to open and close (one finger), and we haven't had issues (even with kids slamming the door while the deadbolt is open).

The Aqara U50 is an excellent smart lock that’s easy to install, feels well-built, and looks sleek on the door. Apple Home Key works flawlessly—unlocking with my iPhone or Apple Watch is fast and convenient. The keypad is responsive, battery life has been solid, and having a physical key backup is a nice touch. It integrates smoothly with my smart home, responds quickly, and just works without hassle. For the price, the Aqara U50 delivers strong security, modern features, and great reliability..

First impression? This thing's got more tech crammed into it than a spaceship. It’s got keyless entry, Apple Home Key, Bluetooth, and even works with Alexa and Google Home. Basically, if you have a smart home ecosystem, this lock's like, "Sure, I can work with that." The Good: Keyless Entry: No more fumbling with keys like a caveman. Just use your phone or the keypad. It's like I'm in a sci-fi movie every time I come home. Multiple Entry Options: You can unlock it with your phone, Apple Watch, or even set up multiple codes for different people. Got in-laws visiting? Give them their own code and revoke it when they leave. Genius. Integration: Works with Apple HomeKit, Google Home, Alexa, and IFTTT. You can even set it up to unlock when your kid gets home from school. It’s like having a personal doorman. Security: This lock is no joke. Meets BMHA Grade 3 standards, which is solid for home use. Plus, you can rekey it if needed, so you’re not stuck if something goes wrong. Easy Installation: Comes with all the parts and screws you'll need. Just follow the QR code instructions and you're golden. The Bad: Bulky Design: This thing is a beast. It's like strapping a mini safe to your door. Not the most elegant, but hey, it’s a smart lock, not a fashion statement. Hub Required: If you want to integrate it with HomeKit or Google Home, you need a hub. More gadgets, more money. They get you every time with this stuff. Battery Life: Runs on four AA batteries. While they claim it lasts long, if you live in a place with harsh winters, you might be swapping batteries more often than you’d like. At least there's a USB-C port for emergency power. Overall, the Aqara Smart Lock U50 is a solid choice if you’re looking to upgrade your home security without breaking the bank. It’s got a few quirks, like needing a hub for full functionality and its less-than-sleek design, but the convenience and peace of mind it offers are worth it. I’m giving it 4 out of 5 stars because, let’s face it, nothing’s perfect, but this comes pretty close for the price.
