1. はじめに
The Aqara Smart Lock U200 is designed to provide convenient and secure keyless entry to your home. It integrates with various smart home ecosystems through Matter over Thread technology, offering multiple unlocking methods and smart features.
2. セットアップ
2.1 互換性チェック
Before installation, verify your door's lock cylinder compatibility. The U200 supports Euro profiles and select Scandi cylinders. For US deadbolt locks, ensure compatibility with backsets of 2-3/8" (60mm) and 2-3/4" (70mm).

The U200 requires a 2-in-1 Matter Controller and Thread Border Router for full functionality across various smart home ecosystems. Compatible devices include Aqara Hub M3, Apple HomePod, Apple TV 4K, Amazon Echo devices, Google Nest Hub, and Samsung SmartThings Hub.

2.2 インストール
The U200 is designed for hassle-free installation, often fitting over existing door locks without drilling or screwing. It is compatible with Euro profiles and select Scandi cylinders, as well as US single deadbolts.

For Euro Mortise Locks, ensure your cylinder is equipped with an Emergency Function. For US Deadbolt Locks, PH1 screwdriver is needed for installation.


2.3 Door Lock Calibration
After installation, close the door and unlock it. Then, press the Set button for 3 seconds to initiate calibration. The lock will automatically adjust its stroke. Ensure the knob operates smoothly after calibration.
2.4 Power Setup
The U200 lock is powered by a rechargeable Li-Ion battery. It is recommended to charge the battery for 3 hours the first time it is used. As an additional option, a power bank can be attached to the doorknob for convenient charging of the Smart Lock.

The keypad accommodates 1.5V AAA batteries and offers hard-wired powering capabilities. AAA batteries are not rechargeable, and a hardwired setup requires a 12V-24V AC or DC power supply.

3.2 Quiet Unlock Mode
The U200 features a Quiet Unlock Mode, which allows the door to unlock slowly, reducing noise levels. This feature can be activated directly from the keypad and does not require a hub or Thread border router.

3.3 自動ロック
Thanks to the built-in gyroscope, the U200 can remind you if the door is left open and automatically lock it after closure. This feature is available within the Aqara Home app (ensure firmware is updated).

3.4 アプリ統合
The Aqara Smart Lock U200 seamlessly integrates with the robust Matter platform and is compatible with Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, and Aqara Home. With the Aqara Hub M3, you can enable remote unlock and set up automations.

4. メンテナンス
4.1 バッテリー寿命と充電
The U200 lock's rechargeable Li-Ion battery provides up to 6 months of battery life (based on up to 8 daily unlocking and locking actions via fingerprint/NFC). The keypad uses 1.5V AAA batteries or can be hardwired. Monitor battery levels via the Aqara Home app.
4.2 クリーニング
To clean the lock and keypad, use a soft, dry cloth. Avoid abrasive cleaners or solvents that could damage the finish.
5。 トラブルシューティング
If the knob is not smooth after installation, slightly loosen the three screws on the mounting plate to prevent over-compressing the cylinder. If the knob does not turn smoothly after installation, please try reinstalling the unit.
