I did notice the delay on the display when I was testing out the smoker feature but did not see the fan cycle being interrupted. However my Auger On time is slightly different, I found the sweet spot to be 23s. The Average ambient temperature here is around 77f-82f throughout the year, at 23s it gets to 160f and holds quite well there. Smoke+ mode was enabled, but the button on the WebUI - I think I'd like to enable this mode in Hold mode as well, to increase the smoke output. This should be easy enough, but I think we need a separate button for fan cycling in the WebUI. - Again I think this would be a first, I don't think other comercial controllers have the ability to smoke much whilst running PID cycle, at least that's the case with GMG, holds temps amazing tight close to +/-2f but then very little smoke. I agree a separate button for fan cycling is a good idea. |

Just FYI on the current status on this feature. Still validating the changes that are on my local dev environment - will be doing a smoked chicken tonight. :) Once I'm satisfied that I haven't broken anything too much, I'll push to the development branch here. |

The first video is showing the limited use of the encoder Just allows the setting of the initial cook and setting the target temp of the food probes Physical.use.of.encoder.1.mp4The next 2 videos are the app, but as you can see its really limited, there are no ways to control the fan, no smoke + etc. In fact your restricted to using the probes they sell as an extra, there is no way to tune other temp probes. App.settings.mp4This shows the use of recipes with junk still left from the developer. App.recipies.mp4The hardware looks well put together, unfortunately the software execution is really poor, I was planning on developing my own firmware for this but then I found PiFire. |

I haven't got my screens yet but I have found some dimensions for the 1.3" IPS screen so I Updated the face plate to include that. It looks like we can go up to a 1.8" screen without any problems. |

Ugh, so the version of the screen (ST7789) that I picked up with I2C based, which is what I wanted, but it looks like there aren't any python libraries to support this version yet. All of them appear to be SPI based. :( I should have done more research, luckily they are cheap. Let me know if you have any luck finding anything. I may look at some other screens to see what else we can use. Another option to use a larger screen may be to mount it so that it's more on the outside of the grill body, not flush with the surface. Maybe even angled up a little so that it's easier to see. In the meantime, I may work on improving some of the dashboard buttons w/Javascript... I'm a novice at JS, but learning as I go which is fun. |

Very cool! Keep hacking at it. You can get started by copying the
SSD1306.py module and then swapping out the imported libraries to use this
display. Then just replace the commands, etc. for painting the screen.
Might be a good way to learn. :) BTW, I highly recommend this channel on
youtube: https://www.youtube.com/channel/UC6HfeAa0vWeSWS6IcNAjZ2A to learn
more of the deeper Python functionality. The way he goes through his
lessons is excellent for learning.
I'm still not having any luck getting mine up and running. I'm sure I've
got some pins swapped somewhere, but I need to just spend time to guess and
check. :) I'll try the Adafruit libraries... I just hate adding an extra
layer (circuitpython) on top of all the other libraries that are already
loaded (RPI.GPIO).

I like it. I'm cool if you want to do a pull request on the dev branch with your edits / additions for this and maybe document what you have done to install the luma module in the header of the display_st7789.py file. Once I get my new screen, I can start to play with it from there. But take your time, I'm not in any rush at the moment, still waiting on shipping. :) BTW... I found (and ordered) some much more high end 2.5mm jacks to use for the probes. This has been a weak point in my current hardware setup, because my jacks are very low quality and don't work well with all my probes. Not sure where else these could be sourced, and they are expensive, but might be worth it. https://www.amazon.com/gp/product/B01M2AZTUQ |

Awesome! Have fun! I'm going to start adding the physical button controls
to the display module, but will probably prototype it in PyGame first.

Was thinking since the screen is a touch screen, we could use that instead
of physical buttons?

Good thought. I'll look into it. It might take a fair amount of
re-architecture to get the touch to work properly. Also, might require
another library for the touch support. Right now I'm using the version
without the touch screen, but I do believe I have the touch screen version
as well.

Unfortunately, in smoke mode, since it's just a dumb cycle, it's generally
going to run hotter. You could extend the cycle, reduce the amount of
auger on time and see if that helps. Your best bet is to get an Amaz'n
Smoker (
https://www.amazon.com/MAZE-N-Pellet-Smoker-Smoking-Works/dp/B007ROPJ1M)
which will basically smoke at very low temperatures. It's
temperamental though. Also, for cheese, I've found that you will want to
refrigerate your cheese for at least 24 hours after a smoke to ensure full
penetration. Don't try tasting the cheese right after smoking - you will
be disappointed. :)

I'm not sure if this is the place for this question, but I was wondering
about cold smoking. Has anyone tried and was wondering if they could so
what's the coldest they'd be able to do it without a dedicatedcold smoking
device? I know my grill will technically do about 180 but verticals will do
colder, like about 150. I'd like to do cheese and the like. I've seen
people use ice baths on barrel versions and I'd do the same. I was just
wondering if its possible to do cooler with these types of pids controllers
or if it's limited to the type of smoker.

So I really like the smoke+ option as it does seem to help produce much more smoke and seems the grill can hold temps better for the cook but in my opinion there are two things that I feel are issues.
Do you think we could control this with a global or something else so the work cycle loop is not restarted but still be able to toggle it on and off if needed? This might be more moot if # 2 can be implemented.
Maybe something like below You could add a toggle in settings as well I guess. I have not tested this just thought it up today. If you don't mind let me know your thought on this and if it would be a good or bad idea. |

Moving the feature discussion here.
I've gotten the chance to try out the Smoke Plus feature this weekend and overall I think it's an impressive start. However, it is not without issues. There are some necessary fixes / improvements:
I think this will keep me busy for a while. :)
