The lock has been up and running for a number of weeks, and overall it’s been great.
Pros
UWB - amazing tech everyone in the house loves just walkign up to the door and it magically unlocking
Speed - motor is great compared to the previous lock. It unlocks very fast and hasn’t had jamming issues.
Look and feel - good size and good feel to it
Cons
Set-up - complex smart home setups might have headaches. I run Home Assistant and an Apple ecosystem. But my netowrk vlan set-up was making it tough to get everything to play nice. Figured it out and haven’t had issues since. This is more of a Matter short-coming and limitation with vlans
Home Assistant Support - Again might be a Matter limitation, but the controls and data are limited. Would love to see the door status, code management, and most important which code or person unlocked exposed to HA. Don’t know which are Matter limitations vs Aqara gaps at the moment.
Overall this is a great lock and the UWB support alone made it well worth the upgrade.

I think I’m going to try this thing out and get rid of my Level lock

That’s what I did, I removed my Level Lock Pro and I’m glad I gave it a try. The Level Lock Pro is nice, looks great and works well.
The Aqara U400 simply has so much more to offer and works just as good if not better. UWB alone is enough to swap out Locks.
When you walk up to the door, it unlocks and puts a smile on your face as you walk in. (It’s weird)

Is this lock compatible with Apple Home Kit?

My front door is newer and the seals are I guess “tight”. When we close our door we have to push on it just slightly to lock the deadbolt. Does anyone have any recommendations? It’s really the only reason I haven’t made the move to a smart deadbolt.

One question: is it anti-picking?
Got Dufy locks last year with all their cameras. Feeling Aqara has really moved up in the game in the past 16 months since I bought everything. Convincing myself to not start over again to switch/consolidate ecosystems.

Hi everyone,
One of the biggest benefits for me is early morning runs with my dog. My wife is usually still sleeping, and with the U400 I can just walk out the door without grabbing keys or worrying about noise. No pockets, no key jingle, no double-checking the lock.
The UWB unlock has been very consistent. I approach the door, it unlocks automatically, and I’m out. When I get back, the auto-lock kicks in, which has been huge for peace of mind. I used to have those moments later in the day where I’d think, “Did I lock the front door?” That’s completely gone now.
Day to day, it just fades into the background, which is exactly what I want from a smart lock. It works quietly, reliably, and removes friction from a routine I do every single day.
If you’re someone who runs, walks a dog, or just wants to leave the house without thinking about keys or whether the door is locked, this has been a noticeable upgrade.
Happy to answer any questions if others are on the fence. Aqara Products SmartLockU400

I would really love to get a ULOCK 400 to replace my current Homekey U50. But I have to admit, the jump from $110 to $270 makes is a little hard to justify just for the one functional improvement of walk-up unlock (especially sine we both generally use our Apple Watches for the lock and dont have to get out our phones)

This lock was easy to install. I love just walking up to the door and having it unlock for me. So far battery life seems to be good. I definitely recommend this lock. SmartLockU400

One day I’ll have non-hollow outer doors in my house and I’ll buy so many smart deadbolts
