Features:

-Timeout not closed door reminder.

-Simple installation and convenient connection.
-Record the opening and closing status of doors and windows.
-Mobile phone push opening and closing status synchronously.
-A light sensor is added. After creating a smart scene through the Mijia APP, when the light sensor senses that the ambient light is dimming, it can be linked to the smart lamp to realize the scene of turning on the lamp at the same time as the door is opened at night.
Note* It needs to be used with a Bluetooth gateway or a smart product with built-in Bluetooth gateway function to achieve the above functions.
