The heatermeter is a bit unique in that the PID method(s) that CapnBry uses can control two outputs, a fan and a damper.
When I was doing PID stuff back in the dark ages I think I mostly set up controllers with one input (temperature, pressure, flow, whatever) and one output (valve, burner, heater, vent, whatever).
Is there a discussion somewhere on single input multiple control output algorithms and methods? Maybe even somewhere where CapnBry discussed what he did in the heatermeter?
looking around the googleverse, there's lots of discussions and course-level stuff on single in single out. Almost all the multiple out uses some sort of proportional slaving from one output to the other. Or else feeding the input to separate separate PID controllers for each output.
I can certainly go into the source (thank you Capn for leaving it up and available) but if there was already higher level discussions that would be a better place to start.
Where I'm ruminating on going with this is maybe prototyping an ESP32 based controller for my kamado just for fun. And it beats mowing the yard....which is not fun 8).
Thanks!
