3 probes, 3 different temps in same place

Hi all, just getting my BrewPi Spark v2 build going and so far I’m super psyched for the control I’ll have.

I have three probes (beer, fridge, room) installed and working. The three vary from each other to a small degree - literally. Two of the probes read at 0.1 degree F difference, while the third is 0.2 different.

Should I care? I can’t imagine that difference impacting my fermentation in a significant way.

Is there an ideal location for the one that reads 0.2 higher than the others, such as us that one for “room” and the other two for fridge and beer?
