I have a wifi thermometer attached to the side of my fermenter. I also have another in the same room a few feet away from the fermenter. When a certain yeast gives a temp range for a wort, such as 59-73F, should I use the room temperature thermometer or the one on the fermenter to gauge the correct temp for fermentation? I have heard that active fermentation can cause a reading of as much as 10 degrees higher at the thermometer attached to the fermenter. Cheers!
