Matter over Thread

Works with the home you already have

Native Matter over Thread drops the U200 Lite straight into Apple Home, Google Home, Alexa, SmartThings, Home Assistant and Aqara Home. Thread's low-power mesh keeps the lock quick to respond and easy on the battery, talking directly to nearby Thread devices for fast, stable control.

Unlock your way

Leave the keys at home

Walk up and the lock recognises your phone over Bluetooth; away from home, unlock remotely from the app. Tap your phone on the bundled NFC Sticker Card to jump straight to the app, or ask Siri and Alexa to do it hands-free.

Bluetooth proximity — the Aqara app unlocks as you approach the door
Remote unlock — let family or a guest in while you're out
NFC Sticker Card — two included — tap your phone to open the app instantly
Voice control — unlock with Siri or Alexa

Quiet mode & auto-lock

Locks itself. Quietly, if you like.

A built-in gyroscope locks the door the moment it shuts, so you never leave home unsecured — with an audible reminder if it's left ajar. Slow the motor to Quiet mode at night for near-silent operation, and keep it brisk by day.

Auto-lock on close — the gyroscope senses the door shut and locks it for you
Timed auto-lock — or lock automatically a set delay after closing
Quiet · Standard · Fast — hushed by night, quick by day
Door-ajar reminder — an audible nudge if you forget to close up

Hands-on control

A turn to lock, a spring to open

Prefer the manual touch? Give the knob a 30°–60° turn and the U200 Lite locks or unlocks on its own. Switch on the Pull Spring feature and the lock retracts the latch as it opens, so you walk straight through without touching the handle.

Fits over your existing lock

Upgrade in minutes, charge twice a year

The U200 Lite mounts over your current cylinder — no drilling, nothing added to the outside of your door, and the original key still turns. A 2000 mAh battery lasts up to six months per charge and tops up over USB-C, with a low-battery alert well before you run dry.

No drilling — fits euro-profile and select Scandinavian cylinders
Keep your key — needs a cylinder with an emergency function
2000 mAh, USB-C — up to 6 months per charge, then a quick top-up

Requires a euro-profile (or select Scandinavian) cylinder with an emergency function so the key can still turn from outside. Not suitable for metal gates, and installation is not included. To use the lock within a given ecosystem you'll need that platform's Matter controller plus a Thread border router. Auto-lock and Quiet mode are off by default — enable them in the Aqara Home app. SG availability of specific ecosystem integrations may vary.
