Aqara Sensors

Control from Anywhere, No Hub Required: Built-in Wi-Fi 6 allows you to lock, unlock, and check the status of your door remotely via the Aqara Home app, Alexa, or Google Home—no additional bridge or hub necessary. (*Only support 2.4GHz Wi-Fi.)
Multiple Ways to Unlock & Anti-Peep Security: Open your door via keypad code, app, voice control, physical key, or shareable offline passwords. The Anti-Peep function allows you to enter random digits before or after your real code to hide it from onlookers, while the backlit keypad ensures easy visibility in the dark.
6 Months of Battery Life with Emergency Power: Operates on 4 AA batteries for up to 6 months. If the batteries run out while you’re away, simply use the USB-C emergency port for an instant temporary charge to get you back inside.
Enhanced Safety & Durability: Features Auto-Lock, Night Latch Mode, Failed Attempt Lockout, and Do Not Disturb Mode for total peace of mind. With AES-128 encryption, IPX3 weatherproofing (operating from -31°F to 150°F), and simple DIY installation, it’s built secure to withstand the elements.
Seamless Smart Home Integrations & Automations: Works directly with Aqara doorbells (like the G410) for a live view and one-tap unlocking. Create automations triggered by your lock status and enable Matter connectivity via compatible hubs to sync with Apple Home, Home Assistant, and SmartThings.
