Wi-Fi Fridge Thermometer with Phone Alerts

A small sensor that sits in the fridge and sends the temperature to your phone. Set a range — say 2 to 8 °C — and it pings you the moment the fridge drifts out of it, wherever you are.

• Wi-Fi (Bluetooth in some stores)
• Phone alerts
• Temperature history graph
• Battery

Why you’d want it: A thermometer tells you the fridge was warm when you happen to look. This one tells you the moment it happens, and keeps a graph, so a bad fridge or a door left ajar can't quietly ruin a month of vials.

Picking tip: Wi-Fi models alert you from anywhere; Bluetooth-only ones alert you when your phone is within range of the house, which is still useful but not the same. The sensor goes on the middle shelf, not the door. Export the history once a month if you want a record.
