About BBQ Meat Thermometers

The art of smoking is mostly about creating the right environment for your food to take on the characteristics of smoked food that you are looking for.  That is your job as home pitmaster. Yes, seasoning, brining, quality of meat, etc. are all very important factors, most of which you can control. But the cooking environment is a huge focus, and certainly creates the need to knowing your working temperature.

The other focus is the temperature of the item being cooked. Nothing worse than thinking you had timed everything perfectly, only to find out you had achieved the right internal temp hours ago and now have a dried-out overcooked product. Brisket is not getting cheaper, and mistakes can be costly. As you will learn in this article, there are some very straightforward tools that will make your barbecue cooking process laser focused and Bluetooth enabled.

Pit & Internal Meat Temperatures

If your life involves more than sitting by the smoker to constantly monitor temps, you need a way to both, monitor temperatures, and maintain your pit temperature while you’re off doing other things. All these Wi-Fi based thermometers come with probes that you can leave in a grill or smoker throughout the entirety of the cooking session.

If you want to cook low and slow, you need to maintain a temperature around 225° for several hours, maybe all day if you’re cooking a whole brisket. Too low a temperature won’t cook your food and the lack of heat can put you in the danger zone for bacterial growth. Too high a temperature and you overcook the meat into a dry and chewy mess. All the BBQ skill in the world will mean very little without accurate readings of the temperature of the cooking environment and the internal temperature of the food.

Digital wireless thermometers come with both ambient and internal meat probes. The ambient probes are uniquely designed to slide into a special clip that mounts easily onto your grill grate. The internal meat probes are simply inserted into the meat and will remain there throughout the duration of the cook. You just want to be sure that the both the ambient probe and meat probe(s) are not placed directly over any flames.

A Wi-Fi thermometer for your smoker lets you check the temperature of your meat and your entire cooking process from your phone at a glance. These devices feature multiple probes, so you can keep an eye on each piece of meat and your ambient temperature simultaneously. You can configure the phone app to send you alerts if one of the probe thermometers goes too high or too low. It’s like getting an emergency call, “This is Meat! I’m in trouble here…”

About Pit (Thermostatic) Controllers

These fans turn on as the ambient internal temperature drops, adding air to the fire which increases the temperature. It’s like a thermostat for your house, except running hotter. The more advanced models let you create more complicated programs so you run the smoker at different temperatures for different segments of the cook.

For control that’s even more automated, all the thermometers we feature in this article have the capability to control a pit fan.

About Bluetooth Connectivity

Wi-Fi is a step up over Bluetooth thermometers at this level of complexity. Bluetooth links up one phone to your thermometer with a direct connection, limited to about 100 feet minus losses to walls. A Wi-Fi thermometer reporting data to the cloud has basically infinite wireless range, so you can keep an eye on your pork butt while running to the store. Some of the best products here do both Wi-Fi and Bluetooth so you can use them to their full potential at home or take them out camping where there’s no Wi-Fi without sacrificing performance. When it comes to grilling you can use a Wi-Fi meat thermometer but it may be a bit of an overkill, so while our pick for the best Grilling Thermometer is Thermoworks’ Signals, wireless probe thermometers like the Meater+ are designed for simple grilling tasks – read more about these probes devices here.

Below are the results of our testing to rank the best BBQ and grilling thermometers on the market today.

Think About How Many Probes You’ll Need

This number will also likely be based on what you’re cooking, but how many temperatures probes your meat thermometer comes is an essential consideration in choosing one. A good Wi-Fi BBQ thermometer should be accurate, and should feature at least two probes, though more is better. Smoking a piece of meat likely requires at least two probes, so you can monitor both the internal temperature of the meat, and the ambient temperature of the grill. If doing multiple pieces of meat, you will want multiple probes. If you’re just grilling steaks or chicken, you can likely get away with just one probe or an instant read thermometer – same for baking and other kitchen tasks.

What Makes a Good Thermometer for Barbecue?

There are two goals in getting and using a remote thermometer for your barbecue and smoking endeavors. First is measuring the internal temperature of the item being smoked or cooked. With larger items, or even differing items in the same batch, this means having multiple probes that can monitor different areas of the food, and different foods. This is not a hypothetical example; spatchcock a turkey as we did for last years Thanksgiving meal and cook it on the smoker. The standard rule of thumb is to target 165 degrees. Except that really, that tends to overcook the white meat portions. They will actually be done 10-15 lower than the dark meat. At 155 you will get clear juice in the center of the breast. At 165 you will eliminate the red bones in the hind quarte and get properly cooked dark meat. Being able to monitor both sections is really important.

The other area to monitor is the cooking environment. This uses an ambient temperature measuring probe, shaped differently from the piercing thermometers used to measure internal temps. Humidity and smoke quality are important, but the temperature is still the most important. Which is why we selected the products that we will explore here. Both of them allow multi-point monitoring, and they go one step further with a bonus feature. You can actually influence the temperature of your cooking environment by integrating these devices to your equipment.

Simplicity & Durability

There should be alerts for high and low temperatures for each channel, and those alerts should be definable to both the base station and your phone. Temperatures and alerts should be easy to read and set from either the base station or the phone.

Closeup buttons on Signals

Wireless setup should be easy, and not require punching in a lot of data into a few buttons. The data produced from the thermometer should be easily accessible and annotatable. The device should be able to operate without a Wi-Fi network if needed.

A fan control unit should effectively control temperature to a narrow band. The controller should recognize highly unusual problems like the lid being open and throw up an alert instead of just slamming the fan to maximum.

A Wi-Fi thermometer should be able to stand up to the ordinary vicissitudes of barbecue life: rain, heat, cold, falls, and more. There are enough wires around with the probes, so an internal battery is preferred.

If you’re looking for something a little cheaper and like the idea of wireless cooking, check out the results from our wireless probe thermometer testing.

Why the bi-metal thermometer that came with your grill sucks.

Bi-metal thermometers and gauges that come with your grill or smoker can’t be trusted.

bi-dial thermometers not accurate

The coil method they use is not nearly as accurate as more advanced digital thermometers, and the thermometers are usually built to poor quality standards. As a result, these kinds of bi-metal dial thermometers unreliable and prone to very inaccurate temperature readings, often off by up to 50 degrees! They’re also quite slow, taking 30 seconds to a minute to read the final temperature.

Hopefully, you were only planning on using these gauges for monitoring the ambient temperature of the grill. Even if they were accurate, they aren’t designed for using on meat – which is why they sit in the lid of the grill, way too high up to actually tell you even the ambient temperature of the grill.

So why even bother with them?

“It’s so hard to get that perfect bark on a brisket with a bi-metal dial gauge because they’re rarely ever accurate. I’ve tested many of them and find that they are usually of by at least 15°F and seen them off by as many as 50°F straight from the factory.” — jacob cordero

High Tech

Fireboard 2 High Tech Technology

These folks do like their tech, and now so do we. First, the basics. The device has built in Li-Ion batteries that will easily power through a 24 hour cook time period, and will re-charge easily with a USB base in 4-6 hours. The device has 6 thermometer inputs for flexible use with large cuts or differing foods, along with the probe measuring ambient temperatures. All probes us the same plug in for ease of use.


fireboard thermometer Connectivity

When it comes to communication, the Firebird really begins to spread its wings. First choice, like most of use in some fashion on our smart phones, is through Bluetooth. The proprietary app allows for easy monitoring and control of all the inbound information, and the ability to change the parameters as needed. The device is also Wi-Fi compatible allowing remote monitoring from virtually anywhere. You can even connect through Alexa with voice commands when your hands are busy.


Fireboard Thermometer Data stored on cloud

As a result of collecting so much data from both methods, the apps allow you to build your own cloud stored library of process and cook techniques that work well for you. Setting an expectation that is based on your own experience is an exciting way to hone and perfect your barbecue skills. The data synchronization can go directly through the Wi-Fi, or indirectly via Bluetooth if the Wi-Fi is unavailable. Then you can download for your own records and building essentially your own cookbook.


fireboard thermometer hardware

The probes come with 6-foot braided wire covered leads offering heat resistance well over 550 degrees. The base unity has a large display that is easy to read in most light conditions, and is capable of reading temperatures from -94 degrees to 752 degrees. Yes, they do offer upgraded sensing probes for temperatures that extreme.

Ease of use

All aspects of the connectivity and hardware are very approachable and easy to use. Once your initial connectivity is established things sync up naturally and with little bother. Alerts and communication points are very intuitive, and the directions are written in fairly straightforward language.


Fireboard thermometer Blower fan system

With the Drive Fan Cable, you integrate the Drive Blower fan system for keeping your temperature where you want it.  The unit blows at 20CFM, more than enough to breath life back to the fire when the temperature has begun to fall off. For charcoal or wood burning systems this is a great addition. For more on how the Fireboard 2 stacks up to other simaular Wi-Fi devices, see our full testing and results here.

Smoke X4

Extended Range

Smoke X4 testing transmission distance

The full name of this unit is Smoke X4 Long-Range Remote BBQ Alarm Thermometer. It lives up to that name and then some. Bluetooth and Wi-Fi connectivity are restrictive in some ways and subject to signal degradation over long distances without being boosted along the way. ThermoWorks uses RF technology to offer an astounding line-of-sight range of almost a mile and a quarter, or two full kilometers.


smokex4 thermometer Accuracy

ThermoWorks does take geekdom to a whole new level. It is no surprise that their high-quality consumer products do so well. The company has an internationally accredited laboratory dedicated to calibrating devices related to temperature. They are literally the experts in this field with equipment that has published accuracy to +/-0.000015 degrees Celsius. We surely don’t use that kind of accuracy when barbecuing, but it is pretty cool knowing the manufacturer of your measuring device has that capability.


Smokex4 thermometer Hardware

Not everyone wants to use their phone for everything, we get that. The Smoke X4 has the base unit, then has a separate receiver unit, allowing you to use your phone for phone stuff. The coordination of these two devices allows for the long-range communication. We have certainly taken our barbecue show on the road, and out in more remote environments not needing the phone is handy. Both devices use ‘AA’ batteries. The receiver gets 1,800 hours, the base unit gets 330 hours. The base unit can also be powered through an AC adapter.

As careful as we try to be, the barbecuing environment is not without hazards, particularly for electronics. Even if is just a sloshed beer, risks abound. Alleviating one the bigger risks, ThermoWorks produces these devices to provide splash protection rated to ISO66. Basically, safe from everything short of submersion.


smoke x4 thermometer Probes

The Smoke X4 manages four probes with all the data easy to read on the base unit or the receiver unit. The package includes three food sensor probes and one ambient temperature probe. These have the same exacting standards of precision that the company is known for. One great touch is that the probes have a colored silicone ring at the probe and 4 feet away at the plug for ease of identification.


connecting Billows to SmokeX

This unit can drive the proprietary ‘Billows’ device that is a fan for bringing your fire back to life and facilitate more constant temperatures in your cooking environment. If using Bluetooth is important, they have devices that use that, cloud storage and all those bells and whistles. All of this makes it come as no surprise that ThermoWorks is very well represented throughout competitive barbecue, helping multiple teams bring home the awards.


We see each of these systems as great choices we are confident will deliver the results you want for superior barbecue. This should help you with the differences, and similarities, so that you can see which is a better fit for how you approach the craft of barbecue.
