WiFi Refrigerator and Freezer Monitoring in One Device

Use NS3 as a WiFi fridge thermometer for two nearby cold-storage zones. The temperature + humidity probe fits the refrigerator compartment, while the temperature-only probe tracks the freezer.

Freezer Alarm Notifications on Your Phone

Set independent temperature limits and receive alerts when readings move outside the configured range. Offline notifications, remote mute and an anti-false-alarm delay help you respond without treating every brief door opening as an emergency.

Dual Probes for a Fridge-and-Freezer Pair

Both 4.92 ft (1.5 m) probe cables connect to the same display. Keep the monitor outside the appliance, route the thin cables through the door seal and use it for adjacent refrigerator, freezer or reptile warm-and-cool zones.
