Effortless installation, ultra-low energy use, and reliable open-close monitoring.
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 (sold separately).
When you open the door in the evening, the Aqara Door and Window Sensor can be automated to 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.
The sensor is energy efficient; one battery can last over 2 years under normal usage.
