WiFi Freezer Alarm with Two Sensors

This WiFi thermometer includes two wireless sensors and a hub that continuously monitors refrigerator and freezer temperatures. It is designed for homeowners, RV owners, and laboratory staff who need immediate awareness of temperature excursions that could spoil food, vaccines, or experiments. The system sends alerts through three channels so you can act quickly from anywhere.

2.4GHz WiFi Only with 131ft Sensor Range

The hub connects solely to 2.4GHz networks and will not join 5GHz bands, which may require router configuration in modern dual-band homes. Each sensor must remain within 131ft of the hub, and the hub supports up to 30 sensors in total. Hub offline alerts notify you of power outages, but the hub itself needs mains power and network access to relay data.

Replaces Standalone Thermometers Without Remote

Unlike basic analog or digital thermometers that only show a local reading, this kit adds push notifications, email alerts, and an 80dB audible alarm on the hub. The upgrade is worth it when you cannot be on site to hear a beep or check a display, such as monitoring a garage freezer, a hot tub, or a laboratory incubator overnight.

Questions about this item

Should I buy the two-sensor kit or add more sensors later?

The hub supports up to 30 sensors within 131 ft, so you can start with the two included sensors and expand coverage whenever needed.

What does the ±0.9°F accuracy mean for my freezer?

Readings stay within nine-tenths of a degree Fahrenheit of the true temperature across the full -40 °F to 257 °F range, giving reliable alerts for food safety.

Does the 2.4 GHz Wi-Fi limit where I can place the hub?

The hub connects only to 2.4 GHz networks, so it must be within range of that band; Ethernet is not available on this model.
