Light Automation - When you open the door in the evening, the Aqara Door and Window Sensor will send a signal to the Aqara Wall Switch to turn on the lights. No matter how late you get home, the lights will automatically turn on.
Security Reminder - Turn on alarm mode when you leave the house or when you are asleep. If a door or window is opened, the Hub will sound an alarm and send a notification to your phone.
Aqara Door and Window Sensor T1 detects the current status of doors or windows via the distance of the magnets inside the sensors between the sensor and the magnet. The sensor is also energy efficient and one batter can last over 2 years under normal usage.
