Smart Freezer Thermometer Kit with LoRa Hub, Three Sensors, App Alerts and Five-Year Batteries – YoLink

A smart freezer thermometer kit uses long-range LoRa communication to monitor three refrigerators, freezers, greenhouses or other spaces without adding traffic to Wi-Fi. The selected YoLink package includes one hub and three white temperature sensors.

Sensors report to the YoLink app from up to one-quarter mile in open air and can trigger push, email or limited SMS alerts at custom thresholds. Each sensor measures -4°F to 122°F with up to ±0.36°F accuracy in its central range and runs on two included AA batteries for up to five years.
