The whole point was keeping the temperature sensor readable remotely so that you didn’t have to pay someone to stand around all day.
Absolute worst case, add a second temp sensor for the automated chill cycles. Pretty sure temperature sensors aren’t that expensive.





I feel like you’re not understanding what I am trying to convey. Or I am not being clear enough?
A temperature sensor being hacked is nothing to worry about. Worst case scenario, the hacked sensor will report the wrong temperature and some employee will come running over to the freezer. Upon manual inspection they will realise the temperature is in fact not +50°C despite the exposed sensor reporting that.
The freezers automated freezing/heating just runs off an other separate temperature sensor that won’t be hacked since it is not exposed to the internet.
Don’t this make sense to you? 😅
