Smart 3-Way Alert Thermometer

This WiFi refrigerator thermometer comes as a two-pack of white wireless sensors with a gateway for remote temperature monitoring. Each unit uses a 2.7mm NTC probe delivering ±0.5°C accuracy across a -40°C to 70°C range. The system sends instant app notifications, email alerts and an 80dB buzzer alarm when temperatures exceed your preset limits.

Home Kitchen and Multi-Fridge Users

The kit suits households wanting whole-home coverage because one gateway handles up to 10 sensors within 70m. It is not for buyers who need 5GHz Wi-Fi compatibility, as the gateway only supports 2.4GHz networks. Installations requiring hard-wired Ethernet connectivity or local-only operation without cloud services should look elsewhere.

Capacity and Temperature Headroom

The operating range covers deep-freeze storage down to -40°C and ambient monitoring up to 70°C, handling typical fridge, freezer and hot-tub duties comfortably. Battery-backed sensors continue logging during brief network drops, but the gateway must stay within 100m of the router in open air for cloud alerts to function.
