Stages messed up about ureflowoven-esp32-micropython

Yes, the stage status changes when the it reaches certain temp which is defined by the "stages" in the profile json file. What it does is just letting user know the stage status of the process rather than making a real impact on temp control, except that the integration part of the PID is only enabled when it reaches 'reflow' stage.

The target temp the temp control logic tries to sync with is defined in "profiles" in profile json, along with the corresponding timeline.

That was implemented by adafruit in the original code, and I don't think it's not reasonable, nor can I think of a better solution, so I didn't change it.

I assume tuning the PID params should improve the performance of your hardware. I would suggest increase Kp and Ki, and decrease Kd.

As it turned out, the problem with the curve falling could be fixed by PID tuning. Yet, I don't find it logical that the displayed stage changes with the reaching of the temperature. The stage is specified by the profile, so it would be more logical to change the state once the time is reached. If the temperature doesn't reach the specified value because the PIDs are wrong (as in the photo above) that is a different problem to fix, but still, I would expect the machine to report the phase specified in the profile.

I'm not sure which way is more logical but think it not a big problem as long as the actual temp can be well controlled to meet the ideal profile.
