Work Well Feels Solid/Premium.. Pairing to the Aqara M3 Hub Thread over Matter was a little Gimmicky.

I like this lock mostly because there are very few smart options that aren’t deadbolts. The silver finish looks good and feels solid in the hand. It doesn’t feel cheap, but it’s also not on the level of a high-end decorative handle set. For me that’s fine, it fits in well with our foyer and doesn’t stand out in a bad way. Installation was straightforward. I followed an online video just to be sure I was doing it right, and everything needed was in the box. Adding it to the Aqara hub was simple, and then bringing it into Home Assistant via Matter and into Apple Home via Matter was also easy. Apple HomeKey works great on this lock. You also get multiple ways to unlock: physical key (included), NFC keycard (not included), Apple HomeKey, and Bluetooth through the Aqara app. Fingerprint unlocking is where things fall short. That was the main reason I bought this lock. The idea is you grab the handle naturally, it reads your thumb, and the door unlocks. The advertised 99% accuracy is nowhere near my experience. With just one thumb enrolled, it worked maybe 40% of the time. I ended up registering the same thumb as three separate fingerprints to try to capture different angles and grip positions. That bumped it up to around 75%, but that’s still not good enough. It definitely fails the “wife test” since she’s had to call me a few times because it wouldn’t unlock for her and I had to open it remotely. Battery life seems fine so far, but I’ll know more over a full year. In Home Assistant, you can see the firmware version, battery percentage and voltage, and tweak settings like how long the lock is disabled after failed attempts, which is nice. In short: it’s a good-looking, solid-feeling smart handle lock that fills a gap in the market and integrates well with Home Assistant and Apple Home via Matter. But if you need fingerprint unlocking to work almost every time, this version isn’t there yet. I’ll be watching to see if Aqara releases an updated model with better fingerprint accuracy before I buy another one for another door.

I bought 2 and although It can be a challenge to program these are the best and fastest fingerprint door locking handle on the market IMO. They can be setup and programmed via bluetooth prior to actually installing on the door, just pop the batteries in and using the ACARA app, create users and enter passcodes and fingerprints. Very study heavy duty door handle. Super fast. If that is all you want that's all you need to do. If you need to make changes or check your battery level you will have to be within 30' of the lock to be able to connect to it via the Acara app If you want remote functionality and notifications you'll need an Acara M3 hub to bridge these doorlocks to your wifi network. I have the Acara M3 hub and have connected and integrated it into my HomeAssistant server. This monitors my battery levels automatically and i can remotely control my locks all from my home assistant. Works awesome. I highly recommend this lock. I have 2 of them on my main house exterior door and my garage main door. Over 6 months of use and batteries are still at 90% under moderately heavy use.

These are the most reliable finger print door lock I have ever used in a residential application. The read speed and accuracy is the fastest I've ever experienced. Having the NFC unlock option via HomeKit is also great for if you're wearing gloves. The installation and setup instructions are via a very simple Youtube video, which is also straightforward. The only challenge I ran into is that it steers you into believing you need a Aqara hub for Homekit control; This is not the case. Once the device is setup in the app, open the Apple Home app and manually add the device using the QR Code. It will add quickly and pairs reliably.

2nd review purchased feb 2025 lock no longer functioning as of today September 20 2025 .7 month life span! Smart lock worked great the first 6 months. It started with outside door handle falling off in my hand. Then after repair fingerprint sensor not working! Waited as the keypad , fob and apple key still worked! Was instructed by manual to factory reset to potentially reclaim fingerprint reader! Did this today. Now nothing works app can’t find smart lock. Smart lock won’t go into pairing mode. Won’t pair with matter with blue tooth or its magic pair feature. I’m an experienced home automation technician and I was testing this device to recommend to clients! Disappointed!!! Let’s see what the tech support does. It’s easier to get in contact with the prime minister . Support contacted me ! September 22 ! They decided to send me a replacement unit! They were very nice and accommodating! I was taken care of swiftly! Let’s hope the new unit last more than 6 months.
