I’ve never used a BBQ temperature controller. I’ve had my Big Green Egg Large since Christmas 2025 and cooked on it about 35 times, all on the vents, and my longest cook was a thirteen-hour pulled pork that didn’t need topping up. A controller is a small fan on the bottom vent that holds the temperature for you. I think it earns its money if you cook for a living, if you can’t stay outside for a long cook, or if you cook overnight and want to sleep. For everyone else, learning the vents is part of the fun, and a controller takes some of that away. I haven’t used any of the controllers below, so what I say about them comes from the makers and from reviewers who have. I’m going to try to get hold of some of these and test them over the coming months, and I’ll update this page when I do.

Key takeaways
- I’ve cooked on my Egg about 35 times without a controller. My thirteen-hour pulled pork held its temperature on the vents alone, and I didn’t have to add charcoal.
- On my Egg, 120°C (250°F) is the bottom vent about 99% shut, and 220°C (430°F) is a finger’s width open, maybe two. Learning that is part of the fun, and it’s the job a controller does for you.
- A controller and fan in one kit costs from about £187 (the Flame Boss 400 kamado kit, shipped from the US) to £469 (the BBQ Guru UltraQ kit).
- On a Weber kettle, I’d buy the kettle first and learn the vents. If you still want automation after six months to a year, Weber’s Kettle Smart Ring is £289.
- If you’re buying a kamado anyway and know you want a fan, Kamado Joe’s Konnected Joe has one built in, at £1,999.

Best overall: Flame Boss 400 kamado kit, £186.88

A Wi-Fi controller with a fan and an adapter for a kamado’s bottom vent. On Amazon UK it’s sold and shipped by Amazon US, and the £186.88 includes about £32 of estimated import charges.
Bill McGrath tested the FB400 for AmazingRibs and wrote that “the temperature regulation is the best that I have observed to date”. He also found the app’s instructions “on the sparse side”.
Consider it if you have a kamado and want the cheapest kit that comes with the fan.
Skip it if you’d rather buy from a UK shop, because this one comes from the US.
Best for: kamado owners who want a complete kit for the least money.
Best for a Big Green Egg: Big Green Egg EGG Genius, £330

Big Green Egg’s own controller. It clips into the Egg’s draft door, with one wire that clips to the grid to read the temperature inside and one probe for the food, and a small fan that blows air in when the temperature drops. You run it over Wi-Fi from your phone, tablet or computer, and it has to be plugged in. It’s £330 from Big Green Egg UK.
Vindulge tested one and found it “worked perfectly” with the Egg 70 feet from their router, through three thick walls. They also found “the plastic housing is not as durable as other units”, and that it isn’t weatherproof, so it shouldn’t be left out in the rain.
Consider it if you have an Egg and want the controller made for it.
Skip it if you have any other BBQ, or you want something that can live outside.
Best for: Egg owners who want Big Green Egg’s own.
Best for a Weber kettle: Weber Kettle Smart Ring, £289

A ring with a fan and a screen that sits under the lid of a Weber kettle. Weber says it fits 57cm Weber kettles but not the Compact or any kettle with a hinged lid, so it fits the Master-Touch GBS but not the Master-Touch Premium.
James Hills reviewed it for Mantripping in August and said it “behaves more like a convection oven with a fire at the bottom”. He also found it has to stay plugged in for the whole cook, through a USB-C port, and that Weber doesn’t include a battery.
On a kettle, I’d buy the kettle first and learn the vents. If you still want automation after six months to a year, add the Ring, and if it never feels worth £289, don’t buy one.
Consider it if you own a 57cm Weber kettle without a hinged lid.
Skip it if you have a kamado or any other kettle.
Best for: Weber kettle owners who’ve learnt the vents and still want automation.
Best for cook graphs: FireBoard 2 Drive and Drive Blower Fan, £269 plus £76.49

The FireBoard 2 Drive is a six-channel Wi-Fi and Bluetooth thermometer that can run a fan, and the G3 Drive Blower Fan is sold separately. BBQ Land sells the Drive for £269 and the fan for £76.49. The fan comes with two kamado adapter plates, and BBQ Land sells other adapters on their own.
Dean Schumann reviewed the pair for Smoked BBQ Source, on a set FireBoard sent him for free, and said “the app is class leading”. He also found there were “no actual instructions for installation” in the box.
Consider it if you want to watch several probes at once and look back at graphs of your cooks.
Skip it if you only want the fan control, because you’re paying for six channels.
Best for: anyone who wants the cook graphs as well as the fan.
Cheapest from a UK shop: Inkbird ISC-007BW, £199.99

A controller with an adjustable fan and three probes, two for the food and one for the temperature inside the BBQ. You run it from Inkbird’s app over Wi-Fi or Bluetooth, and Inkbird says it only works with 2.4GHz Wi-Fi.
A member of the BBQ Brethren forum who tried one on a test cook said it “held rock solid temp”, and that there’s “only 1 temp alert setting”.
Consider it if you want a complete kit from a UK seller for under £200.
Skip it if you want to know it’ll fit your BBQ before you order, because Inkbird’s page doesn’t say what it fits or which adapters come with it.
Best for: anyone after the cheapest kit sold by a UK shop.
Best for more than one BBQ: BBQ Guru UltraQ kit, £469

BBQ Guru’s controller with an app over Bluetooth and Wi-Fi. FireFly Barbecue’s £469 kit comes with the controller, the Pit Viper fan, a power supply, a universal adapter, a pit probe and a food probe.
Mark Jenner tested it for Food Fire Friends on a Kamado Joe Big Joe III and a Weber Smokey Mountain, and found the temperature control “hands-free, accurate, and effective”. His complaints were that it has “no battery powered option, it must always be plugged in”, and that the display “tells you very little”.
Consider it if you want an app and a kit that comes with a universal adapter.
Skip it if you want to save money, because the Flame Boss and Inkbird kits both come with a fan for less than half the price.
Best for: anyone who wants an app and one kit for more than one BBQ.
Best without an app: BBQ Guru DigiQ DX3 kit, £349

A controller with a screen and buttons and no Wi-Fi or app, so you set it and check it standing at the BBQ. FireFly Barbecue sells the kit for £349 with a pit probe and a food probe.
Bill McGrath at AmazingRibs found that “the DX3 did an excellent job of temperature control” over about five and a half hours of ribs. He also pointed out that “it does not interface with the internet or smart devices”, and that the instructions in the box were thin.
Consider it if you don’t want another app and you’ll be near the BBQ anyway.
Skip it if you want to check on the cook from indoors.
Best for: anyone who doesn’t want an app.
Best if you own a Signals: ThermoWorks Billows, £66 (plus £216 for a Signals)

A fan rather than a whole controller. It takes its orders from a ThermoWorks thermometer, and Thermapen UK sells it with the Signals or the RFX Gateway in mind. Thermapen says it fits “most fan openings on steel, ceramic and charcoal grills”, and that bigger vents need a mounting kit.
Bill McGrath at AmazingRibs found that “the temperature regulation was excellent”, but that the Signals and Billows together are “pretty basic compared to other thermostatic controllers on the market”.
Consider it if you already own a Signals, because then it’s £66.
Skip it if you don’t. The pair comes to £282, which is more than the Flame Boss or Inkbird kits.
Best for: anyone who already has a ThermoWorks Signals.
Best built in: Kamado Joe Konnected Joe, £1,999

A whole kamado with the controller built in. It has a button that lights the charcoal for you, a control panel on the front and a fan, and you set the temperature on the panel or in Kamado Joe’s app over Wi-Fi. Kamado Joe lists it at £1,999.
Lizzy Briskin tested it for T3 and found “the sensors on the grill are extremely accurate”, but that if she wandered too far from the grill with her phone, “I would lose connection”.
Consider it if you’re buying a kamado anyway and know you want a fan from the first cook.
Skip it if you already have a kamado, or you’re not sure you’ll want the fan.
Best for: anyone buying a new kamado who wants the fan built in.
What a BBQ temperature controller does
A controller has a probe that reads the temperature inside the BBQ and a small fan that pushes air in through the bottom vent. You set the temperature you want, and it runs the fan when the fire drops below it and stops when it’s there. That’s why they’re also sold as BBQ fan controllers. Most have an app, so you can see the temperature on your phone and change it from indoors.
How the fan goes in depends on the kit. ThermoWorks says to close every vent but one and fit the Billows into that one, with a mounting plate if the vent is too big. Big Green Egg’s EGG Genius clips into the Egg’s draft door, and Weber’s Kettle Smart Ring sits under the lid of the kettle.
Do you need a kamado temperature controller?
I don’t think most people do. A kamado’s thick ceramic walls hold the heat, and once you know what the vents do, it stays where you put it. On my Egg, 120°C (250°F) is the bottom vent about 99% shut, and my thirteen-hour pulled pork held its temperature on the vents alone.

Holding a temperature is the easy half. Moving it is harder, because the ceramic holds the heat and coming back down after you’ve overshot can take an hour, so you learn to creep up on the number you want. A controller does that for you. For me, learning it is part of the fun of owning a kamado, and if you’re new to one, I’d learn the vents before you buy a controller.

When a BBQ temperature controller earns its money
If you cook for a living. If you’re catering, cooking in a restaurant, or feeding a hundred people off three Big Joes at an event, you need every grill at the same temperature while you’re busy with everything else.
If you can’t stay outside for eight hours. Maybe it’s a disability or trouble getting about, small children who need watching, a house full of guests, or a job that keeps pulling you inside. A controller means you can still do a long low-and-slow and get on with the rest of the day.
If you cook overnight and want to sleep. A long cook that runs through the night needs someone keeping an eye on the fire. With a controller, the fan does that instead of you.
When it doesn’t
If you’re outside anyway. Chicken thighs, sausages, a whole chicken, ribs, a pork loin or a lamb rump are all done in a few hours, and you’re standing by the BBQ for most of it. Glancing at the vents every so often is enough.
If you’re new to your BBQ. The vents are the main thing to learn on a charcoal BBQ, and a controller doesn’t teach you them. Cook without one for a while first. If you still want one after that, you’ll be deciding from experience.
If the cooking is the fun. If part of why you bought a kamado was learning it and cooking outside, a controller takes some of that away.
What a controller costs you
I cook on my Egg twice a week these days, which is about 104 cooks a year. A 12kg bag of lump does me about 8 cooks, and the bag I use most weeks is B&Q’s Restaurant Lumpwood at £20, so that’s 13 bags and about £260 a year, or £2.50 of charcoal a cook.
Spread over five years of cooking like that, which is about 520 cooks, a controller adds:
| Controller | Price | Per cook over five years |
|---|---|---|
| Flame Boss 400 kamado kit | £186.88 | about 36p |
| Inkbird ISC-007BW | £199.99 | about 38p |
| Weber Kettle Smart Ring | £289 | about 56p |
| Big Green Egg EGG Genius | £330 | about 63p |
| FireBoard 2 Drive and fan | £345.49 | about 66p |
| BBQ Guru DigiQ DX3 kit | £349 | about 67p |
| BBQ Guru UltraQ kit | £469 | about 90p |
If you cook as often as I do, that’s well under the £2.50 the charcoal costs. If you cook once a month, the same controllers work out at about £3 to £8 a cook over five years, which is more than the charcoal.
Frequently asked questions
What is the best automatic temperature controller for a BBQ?
It depends on what you cook on. For an Egg, Big Green Egg’s own EGG Genius is made for it. For a 57cm Weber kettle without a hinged lid, it’s Weber’s Kettle Smart Ring. If you want a complete kit for the least money, the Flame Boss 400 kamado kit is £186.88 on Amazon UK, and if you want graphs of every cook, the FireBoard 2 Drive. For most people cooking at home, though, I’d learn the vents first.
Can I fit a temperature controller to my Big Green Egg?
Yes. The EGG Genius clips into the Egg’s draft door, and the kamado kits from other makers come with adapters for a kamado’s bottom vent. Check the maker lists your size of Egg before you buy.
Does a BBQ temperature controller need mains power?
Most do. Big Green Egg says the EGG Genius has to be plugged in, Food Fire Friends found the BBQ Guru UltraQ has no battery option, and Mantripping found the Weber Kettle Smart Ring has to stay connected to power through the whole cook. FireBoard says its Drive can run the fan from the FireBoard’s own battery, but the fan “may not reach full speed on battery power alone”. So you’ll want a socket or an outdoor extension near the BBQ.
Do I need Wi-Fi for a temperature controller?
Only if you want to check on the cook from your phone. The BBQ Guru DigiQ DX3 has no Wi-Fi or app at all. The Inkbird only works on 2.4GHz Wi-Fi, and T3 found the Konnected Joe lost its connection when the phone went too far from the grill.
Will a temperature controller work on a Weber kettle?
Yes. Weber’s Kettle Smart Ring is made for 57cm Weber kettles, though not the Compact or the hinged-lid models. ThermoWorks says the Billows fits most fan openings on charcoal BBQs, and the BBQ Guru UltraQ kit comes with a universal adapter.

Disclosure
I’ve never owned or used a temperature controller, and nobody sent me any of these. My Big Green Egg Large was a Christmas present from my sister Kate. Big Green Egg had supplied it to her for a paid content partnership, which has since ended. Smoke and Lump has no commercial relationship with any of the makers or shops on this page and earns nothing from the links. More in the affiliate disclosure.
The verdict: do you need a BBQ temperature controller?
Most people cooking at home don’t. I’ve done about 35 cooks on my Egg on the vents alone, including a thirteen-hour pulled pork, and learning the vents is part of the fun. If you cook for a living, can’t stay outside for a long cook, or want to sleep through an overnight one, a controller earns its money, and the Flame Boss 400 is the cheapest complete kit. For everyone else, learn the vents first.
