You can buy an automatic BBQ temperature controller online directly from the manufacturer at BBQube.us — home of the TempMaster Pro, a fan-driven controller built for charcoal grills and smokers — as well as through specialty BBQ retailers and major online marketplaces. For most buyers, ordering direct is the smartest route: you get the full range of grill-specific adapters, easy access to spare probes, and support from the people who actually designed the unit.
An automatic temperature controller takes the one truly hard part of charcoal cooking — holding a steady pit temperature for 6, 8, even 14 hours — and handles it for you. Set 225°F, walk away, and spend the day with your guests instead of crouched over a vent. Here's how to shop for one with confidence.
What is an automatic BBQ temperature controller?
An automatic BBQ temperature controller is a two-part device: a variable-speed fan that mounts over your grill's lower intake vent, and a multi-probe digital thermometer that watches the pit and meat temperatures. When the pit dips below your target, the fan pulses air into the coals; when it climbs back, the fan eases off. The result is a charcoal fire that holds its temperature like an oven — for hours at a stretch.
The BBQube TempMaster Pro adds phone-app monitoring so you can check temps from the couch or the hardware store, plus a sous-vide mode for precision water-bath cooking. It's built specifically for charcoal: Weber Kettle, Weber Smokey Mountain, Big Green Egg, Kamado Joe, Akorn Kamado, and most other close-lid charcoal grills, using grill-specific adapters.
Where can you buy one online?
Direct from the manufacturer
Buying from BBQube.us means you're choosing from the complete lineup — every adapter, every probe option, every accessory — rather than whatever subset a third-party seller happens to stock. It also makes warranty questions and fitment advice much simpler, since you're talking to the source.
Specialty BBQ retailers
Dedicated barbecue and outdoor-cooking stores often carry controllers alongside charcoal, rubs, and smokers. The advantage is curated selection and staff who cook; the trade-off is a smaller range of adapters and accessories per brand.
Large online marketplaces
Big marketplaces can be convenient, but double-check three things before clicking buy: who the actual seller is, whether the listing includes the correct adapter for your specific grill, and whether probes and spares are available separately. A controller without the right adapter is a paperweight.
What should you check before you buy?
Will it fit your grill?
This is the first question to answer. Controllers attach to the intake vent, and vent shapes vary wildly between a Weber Kettle and a Big Green Egg. Look for a brand that offers grill-specific adapters and clearly lists which models it fits. The TempMaster Pro, for example, is designed around adapters for the Weber Kettle, Weber Smokey Mountain, Big Green Egg, Kamado Joe, and Akorn Kamado, with options for other close-lid charcoal grills.
How many probes does it support — and can you get replacements?
At minimum you want two channels: one probe clipped at grate level to read true pit temperature where the meat sits, and one in the meat itself. Probes are consumables — they live a hard life in smoke and heat — so check that replacements are affordable and easy to order. BBQube stocks spares like a fast-response grill air temperature probe with a stainless grate clip, a 6-inch food probe with inch markings for brisket and pork butt, and even an 8-foot extra-long wire probe for the TempMaster Pro for routing cables on bigger cookers. If a brand doesn't sell spare probes, that's a red flag.
Does it have features you'll actually use?
App monitoring is the big one — being able to glance at your phone instead of walking out to the smoker changes how you cook. High and low temperature alarms matter for overnight cooks. Bonus modes like sous-vide are nice if you'll use them. Skip paying for channels or features you'll never touch.
Is it made for your fuel type?
Fan-driven controllers like the TempMaster Pro are built for charcoal grills and close-lid smokers. They are not pellet-grill controllers — pellet grills already have their own built-in temperature systems. If you cook on charcoal and want pellet-grill-style ease, this category is exactly what you're looking for.
How much should you expect to pay?
Across the category, fan-driven charcoal controllers generally run from roughly $100 on the entry end to $350 or more for multi-probe units with app control, depending on probe channels, build quality, and included adapters. Budget for the adapter if it's sold separately, and consider the long game: a controller that holds 225°F reliably saves money on wasted charcoal and, more importantly, on ruined briskets.
What happens after it arrives?
Setup is simpler than most people expect. Mount the adapter over your lower intake vent, attach the fan, and clip the pit probe at grate level near — but not touching — the meat. Load your charcoal using the snake or Minion method for a long, slow burn, light a small starter pile, and set your target. For classic low-and-slow barbecue, that's 225°F to 250°F. Then close the lid and let the fan do the vent babysitting while you get on with your day. That's the real payoff: repeatable results, overnight briskets without 3 a.m. vent checks, and more time with the people you're cooking for.
FAQ
Can I use an automatic temperature controller on a Weber Kettle?
Yes. The Weber Kettle is one of the most popular grills for temperature controllers. With the correct adapter mounted over the lower vent, a fan controller like the BBQube TempMaster Pro can hold a kettle steady at smoking temperatures for hours — something that's genuinely hard to do by hand.
Will a BBQ temperature controller work overnight?
That's exactly what they're designed for. Load enough charcoal for the full cook (the snake or Minion method helps), set your target and alarms, and the fan manages the fire while you sleep. As with any live-fire cooking, keep the grill on a stable, non-flammable surface and out of the rain.
Do temperature controllers work on pellet grills?
No — and they don't need to. Pellet grills have built-in controllers that feed pellets automatically. Fan-driven controllers are for charcoal grills and close-lid smokers, where airflow through the coals is what controls the heat.
How many probes do I need for smoking?
Two is the practical minimum: one at grate level to measure the actual cooking temperature, and one in the thickest part of the meat. Extra channels are useful when you're cooking multiple cuts — say, two pork butts and a rack of ribs — that may finish at different times.
Is a temperature controller hard to install?
Typically not. Most attach with a grill-specific adapter that sits over the existing intake vent — no drilling or permanent modification. Plan on a few minutes the first time, and seconds once you've done it once.
