WiFi Freezer Thermometer with Alarm

The MOCREO WiFi Freezer Thermometer monitors temperatures from -40°F to 257°F with ±0.9°F accuracy using a slim 1.3mm DS18B20 probe. It connects to a 2.4GHz network and sends App push notifications, Email alerts, and triggers a loud 80dB Hub beep alarm.

Homeowners monitoring fridges, freezers, or hot tubs

This system suits users who want remote alerts and local audible alarms for a single appliance or a whole property. It is not for buyers who need a sensor range beyond 131ft or compatibility with 5GHz Wi-Fi networks.

Supports up to 30 sensors per Hub

One H3 Hub connects up to 30 compatible sensors for whole-home coverage including aquariums and wine cellars. Each sensor runs up to two years on its 1800mAh rechargeable battery and stores two years of data for export. The wireless link reaches 131ft, so distant outbuildings may need an additional Hub.

Questions about this item

What Wi-Fi network does the H3 hub require for the sensor to connect?

The H3 hub connects only to a 2.4GHz Wi-Fi network; 5GHz networks are not supported.

Can I add this sensor to an existing MOCREO hub that already runs other probes?

One H3 hub supports up to 30 sensors, so you can pair this probe alongside MS1, ST6, ST9 or SW2 devices already on the same hub.

How do I confirm the system is logging correctly after pairing?

Open the MOCREO Smart app and verify the live reading appears, the temperature graph updates, and the hub emits an 80dB beep when a threshold is crossed.
