For the parent who needs to know the moment a child arrives home from school or the renter securing a ground-floor apartment, this smart WiFi door sensor delivers immediate peace of mind. It focuses not just on home security but on simplifying your daily routines with reliable, instant alerts.
You receive app notifications the second a door or window opens, letting you confirm your teen is safely inside before their text comes through. With no hub or fees, setup is straightforward using the Tuya Smart app on 2.4GHz WiFi. The included batteries last over six months, and the app warns you before they run low, so you are never caught off guard.
Use voice commands through Alexa or Google Assistant to check if a door is closed, and automate other Tuya smart devices—like turning on lights when the front door opens. Its adhesive mount holds firmly on doors, windows, or even drawers, making it versatile for any entry point in your home.
