Tuya WSSTH3 Smart WiFi Smoke Detector: WiFi connectivity for remote alerts
This smart smoke detector is for homeowners who want reliable fire safety without constant maintenance. It goes beyond basic alarms by integrating with your smart home for peace of mind, especially when you're away. The app sends a notification within 10 seconds of detecting smoke, so you can act fast even if you're at work or traveling.
You can check battery status and review alarm history from your phone, eliminating guesswork about its condition. It works with Alexa and Google Assistant for voice control, letting you test it hands-free. Install it on ceilings in bedrooms or hallways as recommended, and use the silence mode to mute false alarms from cooking without disabling protection.
