Very good topic!



Moto Z shot of one of my Rasberry Pis at work, hidden in a fridge.
It is one-wired to 4x DS18B20 sensors in other fridges, logging temperatur since 2013 without any hickups. Only some power outages destroying sd-cards and uptimes.

You can access his http here. The script shows a combined log of all 4 pis and 9 fridges spread over 200qm
