Gaoducash YG400A Smart Smoke Detector Fire Alarm: WiFi connectivity with app notifications via Tuya Smart or Smart Life App
This smart smoke detector is for the homeowner who wants more than a loud beep. It's for the parent who needs to know about a potential kitchen mishap while at work, or the remote caregiver who wants to check on an elderly relative's safety. While many alarms focus on loud alerts, this device gives you proactive peace of mind through your smartphone.
You receive instant app notifications for alarms, faults, or low battery warnings, so you can act fast even when you're not home. The advanced photoelectric sensor reduces false alarms from cooking smoke, and you can link it with other Tuya smart devices—like setting lights to flash red when smoke is detected. The self-check feature sends an alert if there's an issue, and installation is straightforward with included batteries and screws. This isn't just a detector; it's a connected tool that helps you protect what matters most.
