Smart Features
Auto-Lock & Door Magnetic Sensor
The built-in magnetic sensor detects when your door is closed and automatically locks it after a set period (configurable via app). You can also disable this feature for passage mode. The sensor also provides real-time notifications if the door is not properly closed or is left open.


Do Not Disturb & Passage Mode
Activate 'Do Not Disturb' mode to mute lock sounds during specific times, ensuring quiet. 'Passage Mode' allows the door to remain unlocked for continuous access, ideal for gatherings or busy periods.

Temporary Passwords
Generate temporary passwords through the app for guests, cleaners, or delivery personnel, providing controlled access for a limited time.

Real-time Notifications
Receive instant alerts on your smartphone for all lock activity, including unlocks, door status, and low battery warnings.

Voice Control
The lock is compatible with Amazon Alexa, allowing for convenient voice commands to lock or unlock your door.

Exclusive Display Screen
The lock features an intuitive display screen that shows date, time, battery level, current mode (e.g., Passage Mode, Privacy Mode), and password input status.

Battery Management
The lock is equipped with a built-in 37Wh rechargeable lithium battery, providing up to 365 days of standby time in non-Wi-Fi mode. Power consumption will increase in Wi-Fi mode. The eSmartLock app will provide low battery alerts, and the lock itself will also indicate a low battery status on its display.
