I have a Thermoworks Signals 4 channel probe. In the past I've always set the temp based on what the panel says. Now using the signals I put the ambient temp probe near the controllers probe and the temps are wildly different. Somewhere on the order of ~20-30 degrees off or more. So... do I go by the Signals and ignore the controller temp ???? I have the temp set to 235 and the probe is reading 253. I know the temp will fluctuate during the heating cycle. It will show between 240-270 during heating. What does everyone do? Am I over thinking it? Should I go back to setting and go to bed?
