You don’t think there’s anything to learn from 4-5 days of real-time operational data? If you were monitoring your fridge with a unit like this and became familiar with what “normal” looks like, you could spot a problem before it became an emergency.
Cool down time, cycle frequency, cycle length, high and low temps, and the ability to compare this data to ambient temps is all something a glass of water can’t do. I seriously doubt a sick cooling unit could produce those same plots.
If you were logging data from a temperature probe in a glass of water in the fridge, you would see the initial cool down time take longer, but then you would see very little change in the temperature of the water once the cooling unit started cycling. You wouldn’t be able to see the high and low points nearly as well, and the water temperature would always lag behind what the cooling unit was doing. A glass of water also isn’t going to tell you about an intermittent problem that occurred several hours before you took its temperature.
