The short answer
If you smoke on charcoal (kamado, Weber Smokey Mountain, kettle, drum or offset) and want it to hold temperature by itself, get a fan-based temperature controller. The Flame Boss 400 Universal WiFi is the best all-round pick for kettles, bullets, drums and offsets, and the Inkbird WiFi & Bluetooth controller kit is the best value. If you mainly need to watch several temperatures at once, a multi-probe thermometer like the ThermoWorks Signals is the best choice, and it can also run a fan with ThermoWorks’ Billows add-on. For pellet grills, which already control their own temperature, a multi-probe thermometer is all you need.

Controller vs multi-probe thermometer: what’s the difference?
| Temperature controller | Multi-probe thermometer | |
|---|---|---|
| What it does | Reads pit temp and runs a fan to feed air to the fire, holding a set temperature | Reads and alerts on pit and meat temperatures |
| Controls the fire? | Yes | No (unless paired with a fan accessory) |
| Works with | Charcoal smokers with an air intake the fan can attach to | Any grill, smoker or oven |
| Best for | Overnight charcoal cooks and hands-off temperature control | Monitoring several meats, pellet or gas cookers |
A controller only works if the smoker’s lid and vents are reasonably airtight. The fan can add air, but it can’t remove it, so a leaky smoker runs hot no matter what the controller says.
If you only need to watch one or two cuts without wires, see our guide to the best wireless meat thermometers.

1. Flame Boss 400 Universal WiFi: best controller overall
Flame Boss controllers are a long-time favorite among Weber Smokey Mountain and kettle owners. The 400 Universal uses a variable-speed fan that adjusts airflow gradually rather than switching fully on and off, which helps avoid temperature overshoot. It connects over WiFi, so you can set and watch the pit from your phone and view graphs of your cooks, and it comes with two probes. Flame Boss lists it for Weber and Char-Griller cookers, drum smokers and offsets.
Who it’s for: Charcoal cooks who want true overnight, hands-off smoking.
Good to know: this Universal version does not fit Big Green Egg, ceramic or other kamado cookers; Flame Boss sells a separate ceramic version for those. Check fitment before you buy, and plan for a power source near the smoker.

2. Inkbird WiFi & Bluetooth Controller Kit: best value controller
Inkbird’s controller kit gives you most of what a fan controller does for considerably less money. It connects by WiFi and Bluetooth, its fan adjusts speed automatically to hold the pit temperature, and it pauses when it detects the lid is open. The kit includes three meat probes and an oven probe, and it runs on 5V USB power, so a power bank works where there’s no outlet. Inkbird sells it for ceramic and kamado cookers.
Who it’s for: First-time controller buyers on a budget.
Good to know: Check that the fan adapter fits your cooker before you buy. Inkbird also sells the ISC-027BW controller in a separate listing.

3. ThermoWorks Signals: best multi-probe thermometer
ThermoWorks is known for accuracy, and Signals is its four-channel WiFi and Bluetooth BBQ thermometer. Use one channel for the pit and three for meat, with alarms on your phone. On its own it’s a monitoring tool, but it can control the ThermoWorks Billows fan, turning it into a temperature controller for charcoal smokers.
Who it’s for: Anyone who wants a dependable, accurate thermometer that works on any cooker, with the option to add fan control later.
Good to know: The Billows fan is a separate purchase. Check the latest version and color on Amazon, as listings vary.

4. FireBoard 2 Drive: most channels and data
The FireBoard 2 Drive is a six-channel cloud-connected thermometer with a built-in output for a blower fan, so it works as both a monitor and a controller. Its app and cloud logging are popular with competition cooks and people who like to review graphs of every cook.
Who it’s for: Big cooks with multiple meats and people who want detailed cook data.
Good to know: The fan is often sold separately or in bundles, so compare listings carefully.

5. MEATER Pro XL: best wireless probes
The MEATER Pro XL includes four completely wire-free probes that each read both internal meat temperature and the ambient temperature around the meat. With WiFi, you can check from anywhere. No wires means no pinched cables in lids, and it works on rotisseries.
Who it’s for: Cooks who hate wires or use a rotisserie, and those cooking several proteins at once.
Good to know: It doesn’t control the fire. Thin cuts can be harder to probe correctly because the probe must be inserted deep enough.

6. ThermoPro TP829: best budget multi-probe
The TP829 is a simple, affordable four-probe thermometer with a handheld receiver and long RF range. No app, no WiFi setup, just reliable readings and alarms.
Who it’s for: Budget buyers who want to monitor several temperatures without a smartphone.
Good to know: RF range drops through walls and obstacles, and there’s no remote access beyond the receiver.

Also worth a look: BBQ Guru UltraQ
BBQ Guru was one of the original fan-controller makers, and the UltraQ is its WiFi controller. It’s another strong option for kamado and ceramic grill owners. Check BBQ Guru UltraQ on Amazon.
How to choose
- Cooker type: Controllers are for charcoal smokers. Pellet, electric and gas cookers already regulate temperature, so get a thermometer.
- Adapter fitment: Confirm there’s an adapter for your exact grill model.
- Number of probes: One pit probe plus at least two meat probes covers most cooks.
- Connectivity: WiFi lets you check from anywhere; Bluetooth and RF are limited to range.
- Power: Fans need an outlet or battery pack for overnight cooks.
- Airtight smoker: Seal leaks first; a controller can’t fix a leaky lid.
Tips for using a fan controller
- Close the bottom vent fully and attach the fan there; leave the top vent only slightly open.
- Bring the smoker up to temperature gradually. Kamados in particular are hard to bring back down after overshooting.
- Clip the pit probe at grate level near the meat, not touching metal.
- Keep the controller and fan dry; cover them in rain.
FAQ
Do I need a BBQ temperature controller?
Not if you use a pellet, electric or gas cooker, which already control temperature. On charcoal smokers, a controller makes long, overnight cooks far easier.
Do BBQ fan controllers work on offset smokers?
Some do with the right adapter, but they work best on airtight charcoal cookers like kamados, bullet smokers, kettles and drums. Leaky offsets are harder to control.
What is the best multi-probe meat thermometer?
The ThermoWorks Signals is a strong all-round choice for accuracy and app features. The ThermoPro TP829 is a simpler budget option, and the MEATER Pro XL is best if you want wire-free probes.
How many probes do I need for smoking?
At least three: one for the pit at grate level and two for meat. More channels help for big cooks with several cuts.
Can a thermometer control my smoker?
Only some can. The ThermoWorks Signals can run the Billows fan, and the FireBoard 2 Drive has a built-in fan output. Standard thermometers only monitor.
