The Netatmo Smart Smoke Detector 4-Pack offers comprehensive home protection with advanced smart features and long-lasting battery life. This wireless smoke detection system sends real-time notifications directly to your smartphone upon smoke detection, ensuring immediate information even when you are away from home. Each detector operates on a battery designed for 10 years of use, eliminating the need for frequent battery changes and providing continuous protection throughout the product's lifespan. Installation is straightforward with easy ceiling mounting and connection via the dedicated mobile app. The smoke detector continuously self-monitors its battery status, smoke sensor functionality, and WiFi connection, automatically sending alerts to your smartphone if any components require attention. An 85 dB audible alarm activates upon smoke detection, while the smartphone app allows you to silence false alarms remotely without physical access to the ceiling unit. You can configure regular sound test reminders through the app at monthly, semi-annual, or annual intervals to check the alarm's proper functioning. The system operates independently without integration into expensive smart home ecosystems. Made from durable white plastic housing, these detectors maintain a discreet appearance while ensuring reliable smoke detection capability. The 4-pack configuration ensures comprehensive coverage for multiple rooms or larger living areas, creating a connected security network in your home. This smoke detection solution combines traditional safety standards with modern smart technology for enhanced comfort and peace of mind in home protection.
