  1. I don't know how much did you pay for those logging temperature probes but open source "Ruuvitag" would have been a nice option here. The idea is to run single (pretty high quality) Bosch sensor with a small battery and output the data as Bluetooth LE signal. You put a smartphone (or some other compatible device) nearby and use that to log as many sensors as you have. The con side of this setup is that you need additional device for logging, the pro side is that you can keep the logging side in room temperature and monitor all the probes wirelessly. As an additional bonus, you can change the software in the sensor devices to do other stuff that hobbyists have figured out. That said, it seems that the price of Ruuvitag has nearly doubled since it was originally published so it's starting to get too expensive.

  2. Great research! I've been saying for a long time that I want smart fridge but not "smart as in WLAN connection and web browser" but "smart as in it optimizes second derivative of the temperature inside the fridge".

  3. To keep stuff "indefinitely" in freezer, you should keep the temperature below –21 °C (about -6 °F) at all times. I doubt that this single compressor system is far from that.
