Hey there. Short answer, No. This is because you are talking about two independent thermocouples that are placed in different parts of the drum. The digital temp read out on your roaster is reading from the thermocouple that is placed in the center/left of the drum. While the bean temp reading on RoastPath or any profile software you connect to is going to be pulling from the thermocouple in the drum door, fully immersed in your bean mass. These two areas of the drum, even without beans in the drum, are going to be at very different temps. The bean probe that reads out on the side of your roaster is really there to provide a safety function (i.e., shut off the gas solenoid if it reaches a critical temperature). Since it's not fully submersed in your bean mass, like the one in your drum door, it's not the most precise one to roast with. Well it's not that it's not precise, it's as precise as it is accurate, but it's just going to have a much shallower temp curve then the tc stuck in your bean mass. Hope that helps to clarify.

Thanks, Ian.
