Gaoducash 3-pack door sensor Smart Door and Window Sensor: Wi-Fi and Bluetooth dual connecting mode
This smart door sensor is for the parent who wants to know when a child arrives home from school or the pet owner who needs to monitor a door left ajar. While many focus on home security, these sensors offer peace of mind through connection, letting you stay informed without constant checking.
You receive an instant alert on your phone the moment a door opens, so you know your teen is home safe before they even text. The two-way Wi-Fi and Bluetooth setup takes minutes with no hub, and it works with Alexa or Google Assistant for voice commands. Create routines to turn on lights when a door opens, adding convenience to your daily routine. With included batteries and low-power warnings, you never worry about it failing unexpectedly.
