I have been trying to cool a litle Fridge with a certain temperature (20°) for a day with many different settings. The result so far is fluctuating between 19.8° + 21° which does not satisfy me.
My setting is as follows:
A cool box (small refrigerator with Peltier element)
Raspberry 4 with Brewblox
18b20 Temperature Sensors
Can someone explain to me with which settings I can create a stable temperature with my equipment
Thank you I am grateful for any help
