Chatthen CSAF869 Door Alarm with WiFi Sensor and Alarm Light: Emits 120dB alarm and flashes red light when door or window is opened
For parents who need to know when a child comes home from school or for anyone securing a home office, the Chatthen eMylo Door Alarm offers more than basic security. It provides a reliable layer of awareness that lets you focus on your day without constant worry.
When the door opens, the 120dB alarm sounds immediately, and you get an instant notification on your phone through the Smart Life app. The red light flashes to draw attention, ensuring you never miss an alert. You can customize the volume and set timers, so it only activates when you need it, like during work hours or at night.
This WiFi door sensor works with Alexa and other Tuya Smart devices for smart home integration. Link it to turn on lights automatically when you arrive home, adding convenience to your routine. Installation is simple with adhesive tape, and AAA batteries power it for long-term use, with low battery alerts sent to your app.
