Temperature probe placement

The temp probe is most likely not waterproof, indeed. Many people place the temp probe on the side of the fermentor, with some insulation around it to try to isolate the fermentor-wall temperature ...

Is the temperature range listed on the yeast manufacturers' websites ambient or fermenter?

It is definitely the temperature of the fermenting liquid. What you normally would do is fit a thermometer (like a crystal thermometer) against the side of the fermentor. Then you have a good view of ...

What is the purpose of multiple temperature probes in a brew-pi fermentation control setup?

Brew Pi seems to be intelligent to the uses ( ie positions) of the various sensors ( ie in beer vs in chamber) and so appropriate them within the software, using this as part of the PID control. ( ...
