Yes — the BBQube TempMaster Pro fits the Big Green Egg. Like other close-lid charcoal cookers, the Egg works beautifully with an automatic temperature controller because its ceramic body holds heat steadily, and the TempMaster Pro's variable-speed fan replaces the fine hand-tuning you'd otherwise do at the bottom vent. You attach the fan to the lower draft door (usually with a grill-specific adapter), close the top and bottom vents down to a small fixed opening, set your target pit temperature in the app, and let the controller do the breathing.
Why does the TempMaster Pro work so well on a kamado?
An automatic controller regulates airflow. More air in through the bottom vent means a hotter fire; less air means a cooler one. On a charcoal grill, that airflow is normally controlled by hand — you nudge the bottom vent open a hair, wait 15 minutes, check the dome thermometer, and adjust again. It's fussy, and it's the number-one reason low-and-slow cooks go sideways.
The Big Green Egg is one of the easiest cookers to automate because ceramic kamados are naturally stable. Once the ceramic mass comes up to temperature, it resists swings. The TempMaster Pro's fan simply feeds that fire the exact amount of oxygen needed to hold your target — whether that's 225°F (107°C) for a brisket or 500°F (260°C) for pizza-adjacent high heat.
How does the fan attach to a Big Green Egg?
The Egg's bottom draft door is the mounting point. There are two common approaches:
- Slide the fan into the open draft door and close the cast-iron slider down to hold it in place, sealing gaps with the door.
- Use a grill-specific adapter that fits the draft-door opening cleanly, which gives the tightest seal and the most repeatable results.
Which Egg you own matters mostly for fit dimensions. The Large and Medium Egg are the most common, and both accept a fan at the lower vent. XL and Mini/MiniMax draft openings differ in size, so confirm your adapter matches your Egg's model before your first cook.
How do I set up the vents on a Big Green Egg with a controller?
The single most important rule with any fan controller on a kamado: the fan is your only air-in source, so restrict all other airflow.
- Bottom vent: The fan mounts here. Any part of the draft door not covered by the fan/adapter should be closed.
- Top vent (daisy wheel): Set it to a small fixed opening — roughly a dime-to-nickel-sized gap for low-and-slow. This is your exhaust; you don't adjust it during the cook.
- Fire: Light a small area of charcoal (not the whole load) so the controller can bring temperature up gradually rather than overshooting.
If you leave the top vent wide open, the fan will run constantly and struggle to hold a low temperature. A common beginner mistake is opening every vent "to be safe" — do the opposite.
Learn the manual craft first
Even with a controller, it pays to understand what's happening. On a Big Green Egg, holding 225–250°F by hand means lighting a small starter spot, cracking the bottom vent about a finger-width, and setting the daisy wheel to a small opening. Ceramic kamados are forgiving because the thick walls buffer temperature swings — but they're also slow to react. Open a vent too far, wait 20 minutes, and you'll blow past your target and spend the next hour clawing it back down.
That lag is exactly why the TempMaster Pro shines on a kamado. Instead of chasing the temperature, you set 225°F and the fan makes hundreds of tiny corrections you'd never make by hand.

What can you cook on a Big Green Egg with the TempMaster Pro?
- Overnight brisket at 225–250°F with no 3 a.m. vent checks.
- Pork butt — a 9 lb (4 kg) butt at 250°F runs roughly 12–14 hours through the stall.
- Ribs at 250–275°F.
- Poultry at 325–375°F for crisper skin.
- Sous-vide-style low-temp cooks using the controller's sous-vide mode.
You still want a good internal-meat probe and target doneness temps — brisket and pork butt around 200–205°F internal, chicken to 165°F, ribs to tender (probe-slides-in feel, usually 195–203°F).
What about other kamados?
The TempMaster Pro isn't limited to the Egg — it fits Kamado Joe, Char-Griller Akorn, Weber Kettle, Weber Smokey Mountain and other close-lid charcoal grills via the right adapter. If you run an Akorn Kamado, the Adjustable Vent Adapter for Medium-to-Large Kamado and Kamado Joe Jr gives a clean lower-vent seal, and a stainless heat deflector / drip pan sets you up for true indirect low-and-slow. You can browse the full controller and accessory lineup at bbqube.us.
One honest caveat: the TempMaster Pro is a fan-driven controller for charcoal and close-lid grills. It is not a pellet-grill controller and won't run a pellet auger.
FAQ
Do I need a special adapter for a Big Green Egg?
The fan can slide into the bottom draft door and be held by the cast-iron slider, but a grill-specific adapter that matches your Egg's model gives the tightest seal and the most repeatable results. Confirm the fit for your Egg size (Medium, Large, XL) before your first cook.
Which vents do I leave open on the Big Green Egg?
The fan becomes your air-in source at the bottom, so close any uncovered part of the draft door. Set the top daisy wheel to a small fixed opening — about a dime-to-nickel gap for low-and-slow — and don't adjust it during the cook.
Will the TempMaster Pro hold 225°F overnight on a kamado?
Yes. Ceramic kamados hold heat exceptionally well, and the controller's variable-speed fan makes constant small corrections to maintain your target, so an overnight brisket at 225–250°F needs no manual vent checks.
Can I use it for high-temp cooks or just low-and-slow?
Both. The TempMaster Pro can drive the fire up to searing and pizza-range temperatures on a kamado, as well as hold low-and-slow targets. It also includes a sous-vide mode for controlled low-temperature cooking.
Does it fit other grills besides the Big Green Egg?
Yes — it fits Kamado Joe, Char-Griller Akorn, Weber Kettle, Weber Smokey Mountain and other close-lid charcoal grills with the correct adapter. It is not compatible with pellet grills.
