I searched through the pinned topics and the first 12 pages and couldn't find what I was looking for.
For some reason my HM stopped working after doing about 4 cooks with it. I put it away for several months (had to focus on grad school). I recently got it out and magically it's working again. In the process I reinstalled the software and calibrated my probes. I don't remember the PID settings I was using and how much to open the dampers so I'm looking for advice on initial settings, and then how to tune it.
What are some good initial settings to use and are there guides on how to tweak the settings to get it all happy?
How much should I open the dampers?
Is there a guide somewhere on adjust all the PID parameters? I thought there was one but couldn't find it.
Here's what I'm running;
22.5" WSM
a full basket of Kingsford charcoal
HM 4.3 with a rPi3, thermocouple version
Microdamper with the basic fan
I'm in the central valley of California so air temps will be pretty average. The smoker is under an overhang, not far from the house so it doesn't get a lot of wind.
EDIT: I forgot to say I dialed in the servo so it's opening and closing correctly. If I remember correctly from last Spring I would run the bottom damper that the HM is connected to wide open and one damper on top fully open. I think when the servo at the bottom closed 100% it would choke off enough air to bring the temp down. But I'll take advice you have for me.
