WiFi Smoke Detector with 10-Year Battery, Smart Fire Alarm, Compatible with Tuya/Smart Life App

【Reliable Safety Guarantee】Connects to the Tuya/Smart Life app via a 2.4 GHz Wi-Fi network. As soon as smoke is detected, your smartphone immediately receives a notification. To prevent false alarms, the alarm only triggers when the smoke concentration reaches ≥0.45 dB/m². 【10-Year Battery & 10-Year Sensor Warranty】This Wi-Fi smoke detector is equipped with a photoelectric sensor that detects smoldering and slow-burning fires, with a battery life of up to 10 years. 【Device Sharing Function】The device can only be connected to a mobile app. However, you can share it with up to 12 different app accounts, so all shared users can receive real-time push notifications. 【Real-Time Push Notifications】No matter where you are, when the device detects danger or a malfunction, you receive real-time notifications, allowing you to quickly take action to protect your property and your family's safety (Make sure your phone has a cellular or Wi-Fi connection). 【Why Didn't the Smoke Detector Trigger When Burning Paper at Home?】The complete combustion of a bright flame produces little smoke, often insufficient to reach the triggering threshold (≥ 0.45 dB/m) of the photoelectric detector. It is recommended to extinguish three candles simultaneously in a small space and direct the dense smoke towards the side grille of the detector. The alarm should sound after 3 to 5 seconds. You can also press the "TEST/HUSH" button to test the device.
