My first fermentation with my BrewPi controller resulted in near perfect temp control, within .1F. This second fermentation seems to be going quite differently, allowing for sways of up to .8. I know this isn't going to break the beer, I'm just trying to understand why it seems to not have as tight of control anymore. Here is a screenshot of the fermentation:
As you can see, early on in the fermentation the control was nearly perfect. Once it started raising the temp from 67F to 70F is where is seems to have lost control. During my last fermentation, the system never exhibited sways this high. I'm still using the same freezer/reptile heating lamp combo.
Are there any PID parameters that I should be adjusting?
