Vivifly WiFi Sensor 90mm x 63mm x 25mm sku-12426109603

The Vivifly Tuya-compatible KONLEN temperature sensor measures 90mm x 63mm x 25mm, Works with Google Assistant, and is listed as sku-12426109603. It monitors temperature in real time and sends phone alerts through the Tuya Smart or Smart Life app when readings cross preset limits. The app supports remote monitoring, °C/°F selection, history export, and sharing with other users. Its probe has a 1 meter cable for indoor or outdoor measurement; the digital display panel is not waterproof and must stay indoors. Set upper and lower alarm limits, such as 27 to 33 centigrade. Below 27 or above 33, the app receives an alert, the built-in buzzer sounds, and the displayed number flashes. The buzzer's default alarm time is 15 seconds and cannot be adjusted. A DC5V 1A adapter is included. The built-in 3.7V 600MA rechargeable backup battery provides about 6 hours of standby time. Before first use, open the back cover and turn on the battery switch on the circuit board. The stated detecting range is -40 to +120, temperature accuracy is 0.5, and measurement error is ±1, ±3%RH. The sensor uses 2.4G WiFi and does not support 5G. A flashing green indicator shows pairing status. Hold the pairing key for 6-12 seconds until the LED flashes rapidly, 5 times in one second.
