Similar to the nerd question - could you describe your approach to the freezer monitor? I have a cabin I don't live nearby to, and I basically can't keep anything in the freezer. It seems to go out often enough to unfreeze then refreeze the ice cube water.
I was thinking a flat thermistor. Then I started thinking - what if it's not the power, but the freezer itself?
Now I'm getting into a battery to log when power is out, save that state, continue logging temps, then transmit after the wifi (assuming loss of power - although I have a UPS for the modem/wifi that will last a few hours) is available again. This obviously adds complexity.
Would love to hear your approach to that project....
