I recently came across almost exactly this with my smoker! I have a controller which uses ambient and meat temperature probes and a fan to control the fire’s temperature. I need to know when the ambient temperature falls below a certain point as I then have to intervene before dinner is ruined. I also want to know when the fan is struggling to keep up, as that means the fire needs more fuel, and it’s easier to deal with that before the temperature drops too low.

I love that I have taken humanity’s oldest technology and complicated it to the point where I have the same problems as the buildings running our very newest technology. Makes a good brisket though.
