About this item

• Remote Monitoring via APP: These alarms connect to the Tuya APP via 2.4G WiFi, allowing you to remotely monitor doors and windows for pool door alarms, windows, garages, shops, and daily use. If a child or pet unexpectedly opens a door, real-time detection instantly sends an alert to your phone. These are reliable door alarms for kids safety, providing intelligent 24/7 protection and keeping you informed at all times.
• How to Connect the Wi-Fi Door Alarms: Download Tuya Smart app, enable Wi-Fi and Bluetooth. Set the window alarm's main unit to 0, insert 2 AAA batteries. Within 5 seconds, cycle switch: 0-1-0-1. Red light and beep indicate pairing mode. In the app, tap Add Device, enter 2.4G Wi-Fi password to connect.
• Smart APP Control: This alarm offers full-function smart control via the Tuya APP. Receive real-time door/window open/close alerts, and monitor every door alarm sensor and window alarm sensor directly from your phone. Switch between Doorbell/Alarm/Off modes, and adjust volume levels—all remotely to adapt to different scenarios. The device operates on stable 2.4G WiFi for reliable performance. Plus, the APP interface clearly displays the remaining battery percentage, so you always know when it's time for a replacement.
• 3 Modes + Adjustable Volume : This alarm allows you freely switch between 3 modes. Alarm Mode 1: Alarm sounds for 1 minute. Alarm Mode 2: Alarm on door open, off when closed. Chime Mode: Door chimes when door opens. When the magnet separation exceeds 0.78 inches, a high-decibel alarm is triggered with a flashing red light, while an instant alert is pushed via the APP for dual protection—ideal for window sensors for security applications.
• Easy Installation: This door sensor alarm features peel-and-stick installation with double-sided tape—no wiring needed. Simply align the magnet with the arrow mark (gap within 2 cm) for precise, high-sensitivity triggering. It operates reliably in temperatures from -10°C to 50°C, making it ideal for window sensors for security. Powered by 2 AAA batteries (not included), it offers long battery life and low-battery alerts.
