Lately I've been practicing my brisket smoking. Normally I have guests and I play with the smoker temp to get the brisket to rest about 2 hours before the party. Friday I smoked a practice brisket. It's just like a real brisket, but with no party time to aim for. I put the iGrill probes in the point and flat, and then used an iDevice probe to monitor chamber temp.
I set the setpoint to 225 and started the smoke. Initially the PID controller kept the temperature about 20 def F hotter than set point. I was annoyed, but offsets happen so I changed the controller setpoint to to 210 and the chamber temp fell to 223. Close enough.
As the meat temperature rose from 40 deg F, the setpoint and chamber temperature came closer together. When the meat hit 140, the difference was 1 deg F.
The Auber is a multi-step PID controller. Next brisket is 11/21. I'm planning to create a profile that starts at 210, and after 2 hours shifts the setpoint to 225 to see how the chamber temperature behaves.
