Josh,

I think you may be sitting on a gold mine with your BBQ Command Center.

From what I have read, unless I am misunderstanding the information, the Stoker and BBQ Guru are on/off type controls. I think your method with the PID loop and variable damper and fan controls are much more sophisticated and would provide much more control and a rock solid temperature line without the above and below setpoint cycling associated with on/off type controls -- IMHO.

Thanks. It's been a fun little project. I'd have to play with a Guru or a Stoker to see for sure, but I'll bet they use PID loops as well. They just don't vary the speed of the fan. I think they pulse the fan as needed. Same RPM's, just more or less pulses depending on how much of an adjusment to make. I could be way off though.
