Does the BBQube TempMaster Pro Fit a Char-Griller Akorn?

Yes — the BBQube TempMaster Pro fits the Char-Griller Akorn Kamado. You mount the variable-speed fan to the grill's lower vent using the Adjustable Adapter for Akorn Kamado, close the top damper down to a small gap, drop your probes in, set a target temperature in the app, and the controller does the rest. The Akorn's insulated, close-lid steel body is exactly the kind of grill an automatic controller loves.

Why the Akorn is a great match for an automatic controller

The Char-Griller Akorn Kamado is a double-walled, air-insulated steel kamado. Like a ceramic Big Green Egg or Kamado Joe, it holds heat well and — crucially — it seals tightly with a lid that latches closed. That sealed design is what lets a fan-driven controller work: the TempMaster Pro governs the pit temperature by feeding measured bursts of air through the bottom vent, and a leaky grill would just bleed that control away.

Because the Akorn is thin steel rather than thick ceramic, it actually responds faster than a heavy kamado. That's a double-edged sword by hand — small vent changes swing the temperature quickly — but it's a gift for an automatic controller, which reacts in real time so you never chase the dial.

What adapter do I need for the Char-Griller Akorn?

The fan needs an airtight path into the firebox, and every grill's lower vent is shaped differently. For the Akorn you use the Adjustable Adapter for Medium-to-Large Kamado, which is designed to seat against the Akorn's sliding bottom damper (it also fits Kamado Joe Jr and similar 18-inch kamados). The adapter creates a sealed coupling so the fan's airflow goes into the coals rather than escaping around the edges.

Two quick setup notes:

• Bottom vent: With the adapter installed, the fan handles the air. Leave the Akorn's slide damper open enough to seat the adapter; the controller meters the actual flow.
• Top vent: Set the top damper to a small crack — roughly a dime-to-nickel-sized opening for low-and-slow. You want exhaust to escape, but not so much draft that air rushes through with the fan off.

Learn the manual craft first

Before you set-and-forget, it's worth understanding how the Akorn holds temperature on its own — it makes you a better cook and helps you troubleshoot.

The charcoal setup

Use lump charcoal for a kamado; it lights cleaner and produces less ash than briquettes, which matters in the Akorn's narrow firebox. For low-and-slow, arrange unlit lump around a small pocket of lit coals so the fire spreads slowly (a simplified minion method). Add a couple of wood chunks — hickory or apple for pork, oak for beef — buried in the lump.

Use a heat deflector for indirect cooking

Ribs, pork butt, and brisket all cook indirect, meaning the meat isn't over direct flame. A stainless heat deflector / drip pan for the Akorn Kamado blocks radiant heat and catches drippings — essential for even, low-temperature cooking. (Running the smaller Akorn Jr? Grab the Akorn Jr heat deflector instead.) You can add a little water to the drip pan for humidity, which also buffers temperature swings.

Dialing it in by hand

To hold 225–250°F manually, start with both vents barely open and creep up. The single biggest Akorn mistake is opening the vents too far, overshooting to 350°F, then fighting to bring it back down — a sealed kamado sheds heat slowly, so recovery from an overshoot takes ages. Small moves, then wait 10–15 minutes to see the effect. For a deeper dive on fire management and doneness science, AmazingRibs.com (amazingribs.com) is a solid, trustworthy resource.

The set-and-forget upgrade: BBQube TempMaster Pro

Once you understand the craft, the honest truth is this: holding a steady pit temperature for 8–14 hours is the hardest, most tedious part of low-and-slow — and it's exactly what the BBQube TempMaster Pro automates. Set your target (say 225°F), and the variable-speed fan feeds precise air to keep the Akorn locked in, adjusting continuously as fuel burns down or the weather shifts. Multiple probes track pit temp plus one or more meat probes, and you monitor everything from the phone app.

What that means for your day:

• Overnight briskets without 3 a.m. vent checks. Set it before bed, watch the app when you feel like it, sleep.
• Repeatable results. The same 225°F every cook, so your rub-and-timing experiments actually mean something.
• More time with your guests instead of hovering over the grill.

One honest caveat: the TempMaster Pro is a fan controller for charcoal and close-lid grills like the Akorn. It is not a pellet-grill controller — different animal entirely.

A few Akorn accessories worth having

While you're setting up, a heavy-duty dome cover keeps the Akorn's painted steel exterior from rusting between cooks. And if you want to branch out, the Akorn pizza ring turns your kamado into a high-heat pizza oven, with an optional rotisserie add-on kit for the 20-inch Akorn.

Bottom line

The BBQube TempMaster Pro fits the Char-Griller Akorn Kamado with the adjustable kamado vent adapter. Learn the vents and a heat deflector first, then let the controller take over the hardest job — holding temperature — so your smokes become genuinely hands-off.
