Yes—the BBQube TempMaster Pro fits the Weber Smokey Mountain (WSM). You install the included variable-speed fan onto the cooker's lower intake vent using a Weber Kettle/Smokey Mountain adapter, drop the pit probe onto the grate, set your target temperature in the app, and the controller feeds the fire exactly the air it needs to hold that temp for hours.
How does the TempMaster Pro attach to a Weber Smokey Mountain?
The Weber Smokey Mountain has three lower dampers around the base of the charcoal bowl. To run an automatic controller, you seal two of them and mount the fan over the third. The Lower-Vent Adapter for Weber Kettle and Smokey Mountain connects the TempMaster Pro's fan to that single intake vent, giving the controller full authority over the airflow into the fire.
Installation takes a couple of minutes and requires no tools or drilling:
- Close two of the three bottom dampers completely.
- Clip or seat the adapter over the remaining open vent.
- Attach the TempMaster Pro fan to the adapter.
- Set your top vent about half open—the controller manages intake, the top vent stays as your fixed exhaust.
Because the fan now controls the only meaningful air path into the coals, the TempMaster Pro can speed up to build heat or idle down to a whisper to hold a target like 225°F (107°C) without you touching a thing.
Which WSM sizes does it work with?
The setup works across the Weber Smokey Mountain lineup—the 14.5-inch, 18.5-inch, and 22.5-inch models all share the same style of bottom intake dampers. The larger 18.5 and 22.5 cookers hold temperature especially well with a controller because their bigger charcoal capacity and water pan give you a long, stable burn to regulate.
Learn the manual craft first
Even if you plan to automate, it helps to understand what the controller is doing for you. On a WSM, the classic hands-on method is:
- Minion method: Fill the charcoal ring with unlit briquettes, then pour a small chimney of lit coals on top. The fire burns slowly across the pile.
- Water pan: Fill it to act as a heat sink and humidity source—it smooths out temperature swings and makes 225–250°F easier to hold.
- Vent control: Use the bottom dampers to dial airflow. More air = hotter, less air = cooler. The top vent stays mostly open.
The hardest part of low-and-slow isn't the seasoning or the wood—it's holding a steady temperature for 8, 12, or 16 hours without spikes and crashes. That's the exact problem the BBQube TempMaster Pro solves.
Why use an automatic controller on a WSM?
The WSM is already a fantastic set-and-forget smoker by charcoal standards. Adding the TempMaster Pro takes it further:
- No 3 a.m. vent checks. Set your target and sleep through an overnight brisket while the controller holds the line.
- Repeatable results. The same pit temp, cook after cook, regardless of wind or outside weather.
- Phone-app monitoring. Watch pit and meat temps from the couch or the backyard, with alerts when your food hits target.
- Less fuel babysitting. The fan meters air precisely, so you burn charcoal more efficiently instead of chasing runaway temps.
You set your target—say 225°F for a pork butt or 250°F for ribs—and enjoy the day. The multi-probe thermometer tracks your pit and up to several pieces of meat, and the sous-vide mode is there when you want it. Explore the system at bbqube.us.
Is the TempMaster Pro right for every grill?
The TempMaster Pro is a fan-driven controller built for charcoal and close-lid cookers—the WSM, Weber Kettle, Big Green Egg, Kamado Joe, Akorn Kamado, and similar. It is not a pellet-grill controller. As long as your cooker seals reasonably well and you can mount the fan to a single intake vent, the controller can regulate it.

FAQ
Do I need an adapter for a Weber Smokey Mountain?
Yes. The WSM has three lower dampers, so you close two and mount the fan on the third using the Lower-Vent Adapter for Weber Kettle and Smokey Mountain. It seats over the intake vent with no drilling required.
Does the TempMaster Pro fit all WSM sizes?
Yes. The 14.5-inch, 18.5-inch, and 22.5-inch Weber Smokey Mountain models all use the same style of bottom intake dampers, so the same adapter and fan setup works across the lineup.
Where should the top vent be when using the controller?
Set the top vent about half open and leave it fixed. The controller manages intake air through the fan; the top vent simply serves as a steady exhaust.
Can it hold 225°F overnight without me watching it?
That's the main benefit. Set your target temperature and the variable-speed fan feeds the fire only the air it needs, holding a steady pit temp for hours while the app monitors and alerts you.
Will it work on a pellet grill too?
No. The TempMaster Pro is a fan-driven controller designed for charcoal and close-lid cookers like the WSM, Weber Kettle, and kamados. It is not compatible with pellet grills.
