Information Information

Take absolute control of your front door with the Aqara Ultimate Smart Entry Kit. This all-in-one bundle combines our sleek U300 Smart Lock, the AI-powered G4 Video Doorbell, and the next-generation M3 Hub to create the most secure, intelligent, and responsive entry system for your home.

Description Description

See, Speak, and Unlock—All in Sync: Experience total front door command. The G4 Video Doorbell streams crisp 2K video to your phone, while its on-device AI instantly recognizes familiar faces. The U300 lock lets you grant access with a fingerprint, your phone via Apple Home Key, or a PIN. The M3 Hub ensures these devices work together seamlessly for instant response.
The Power of Local Control: The revolutionary M3 Hub is the brain of your system. It runs automations directly on the device ("edge computing"), not in the cloud. What this means for you: When the G4 doorbell recognizes a family member, it can instantly unlock the U300 door lock without any internet-related delay. It's faster, more reliable, and works even when your Wi-Fi is down.
Unrivaled Privacy and No Monthly Fees: Your privacy is paramount. The G4 Doorbell's facial recognition and video recording, along with the M3 Hub's automation processing, are all handled locally. Enjoy features like 7-day free secure cloud and local storage options without mandatory monthly subscriptions tying you down.
Build Your Smart Home Universe: This kit is your foundation for a truly integrated smart home. The M3 Hub is a Matter Controller and Thread Border Router, bridging Zigbee, Wi-Fi, and IR devices. This means you can create powerful automations that extend beyond your front door—unlock the door to trigger lights throughout the house, adjust the thermostat, and open the blinds for the ultimate "welcome home" scene.
Designed for a Modern Home: With its sleek, minimalist design, the U300 lock complements any decor. The combination of easy, keyless entry and powerful, behind-the-scenes automation from the M3 and G4 delivers a sophisticated and effortless living experience that feels like the future.

There are a lot of features! Combine this with the door lock and you’ve got one heck of a set up!By the way, running this, it’s really Apple home and SmartThings. I am fairly certain it would be very seamless with Home Assistant because they have sort of an agreement to make it work wellIf you combine with the door locks, and maybe you don’t need them but you get to even have facial recognition. I’m learning more but there’s just a lot to it. My house is already pretty decked out and I’m really aiming for a very cohesive and professional look and layout. The idea is to sort of prove that you can have a system that is just as good and hopefully even better than some of the gold standard products where you actually need to pay the organization to set it up and they generally will build drivers for you if neededI’m running SmartThings along with Aqara, which does a great job hooking it up nicely to SmartThings and it forms a Zigbee to matter bridge. This video shows up on SmartThings nicely and maybe I can update more later on.Since I have Apple TV 4K, I went ahead and hooked everything up with that as well. It’s not my primary one but since my lock can open with NFC on my phone, I went ahead and hooked it up to Apple for that reason. But I can tell you that this runs seamlessly with Apple as well. Video shows up very nicely, etc.

Works reliably and easy to install

Works great with its own app, and with Apple HomeKit (and HomeKey). Installed easily, and has worked reliably now for a couple of months. It just works. Battery seems to need charging only every couple of months.My only complaint is the keypad is pretty big for mounting outside (much bigger than something like a Ring doorbell). I’d have preferred an option for a more discreet small NFC only pad to use with HomeKey and NFC tags.Installed on a euro door lock with pull spring, using just the screws that clamp it to the cylinder.

Excellent produit

Un article nommé désir, merci.Fait le job.Petit timing pour la pose et la configuration, mais fonctionne nickel chrome. Je recommande.

Setup was not great, seems to work once connected

Works like a charm, this model doesn’t have a neutral, my house is older and it doesn’t have a neutral wire. Works perfectly.

After 3 months

Its so smart and understandable thing! You can hire it for 24/7 and enjoy! Just the only problem is the wire plug! Easily theft can take it out and bring it, the design of that area is awful
