The Auber requires no “magic” to work with any analog electric cooking device. They don’t work AT ALL with any digitally controlled cooking device.
The MB40 I bought needed to be modified (using simple instructions available on the web) to route around the controller and allow the heating element to be controlled by a PID - turning it into an analog cooking tool. Some electric smokers, including some MB smokers, are natively analog and will require no such modification.
And, as I’ve said before, the PID is great for other cooking tasks using tools that are already analog. Like most crock pots, or roaster ovens. I really like it. 22quarts of venison stock placidly processing in my garage at a precise 190° for 24 hours or so makes me kind of giddy.
I’ve used a couple of iterations of MB30’s over the years, and have smoked on a kamado joe using a partyQ. And caveman style using a Weber grill. And over a water smoker. If I had more budget, motivation and time, I’d probably be looking at a reverse flow stick burner. But this MB40/Auber/Mailbox is a combo that works better than any other setup I have used. If you got the impression I think it works better then setups I have NOT used, you are reading more in to my words than is actually there.
Whether Aubers that can be set up with a blower for charcoal is something I never researched. And it really has nothing to do with this thread. I never looked into it, because it had nothing to do with my setup.
I did buy the Auber circulation fan kit, for installation in the MB box - which handily prevents hot/cold spots. Really happy with it.
