Following the basis of https://adam-s.ca/quick-temperature-logging-probe/ I setup a wireless temperature probe to monitor the temperature in my fridge because who knows what the temperature is when the dial is set to 3 😉 (there is a joke about a fridge that goes to 11 somewhere there).
Results were very surprising as the 95% confidence interval was so tight together I though something was wrong. Looking at the trend chart we see that there might be some oscillations if we tracked for longer but this was already a 3-4 day time frame O_o. It would be extremely shocking to me if there were oscillation with a period of 7-8 days.Follow ups.
Follow ups & Notes
- Trial with different locations as obviously positioning further away from cooling coils will have higher temperatures.
- Trial with larger battery bank to get large time frame trending
- This was done on a cheap & old mini fridge so there might be value in testing newer hardware.
- The fridge was heavily stocked with high heat capacity items so hysteresis may be playing a bit of a part here.
- Higher polling frequency, though 15s should be more than frequent enough.
