Aqara Smart Door Lock B50

Your door, in your pocket. No hub required.

With Wi-Fi 6 built in, the B50 connects straight to your home network — no separate bridge to buy. Lock, unlock, and check activity and status anytime through the Aqara Home app, Alexa, or Google Home, whether you're on the sofa or overseas.

Everyone gets in their own way

Keypad passcode, the app, a voice command to Alexa or Google Assistant, or the trusty physical key — pick whatever suits the moment. Offline passwords keep working even without Wi-Fi or a hub, and can be issued or shared to guests remotely.

• Anti-peep passwords — add random digits before or after your real PIN so no one can read your code over your shoulder
• Backlit keypad — the keys light up for clear entry in low light and after dark
• Offline passwords — issue time-limited codes for guests or cleaners — no connection needed at the door

Long battery life, and a way in even at zero

Four AA batteries keep the B50 running for up to six months, and swapping them is a two-minute job. If they ever run flat at the worst moment, the USB-C port on the underside takes a quick charge from a power bank — enough to get you through the door.

Works with what you already run

Out of the box the B50 speaks Aqara Home, Alexa, and Google Home. Pair it with a compatible Aqara hub and it joins Matter too, so it sits alongside Apple Home, SmartThings, Home Assistant and more.

• Aqara doorbells — link with an Aqara doorbell such as the G410 or G5 to see who's there and unlock straight from the app
• Scenes and automations — make the lock a trigger or an action — arm sensors on lock, turn off lights on the way out
• Matter, via a hub — add an Aqara Hub M3, G5 or M100 to bridge the B50 into Matter platforms
