A complete MeatGeek review of the best Bluetooth grill thermometers on the market. With extensive research and testing we bring you the pros, cons, and our favorite value pick for the best wireless digital meat thermometer money can buy.
Comparing bluetooth vs wi-fi
Every self-respecting chef and aspiring grillmaster has a reliable meat thermometer in their arsenal, but it’s no longer enough to just read temperatures accurately; a meat thermometer needs to be wireless-enabled and capable of many different smart functions, letting you monitor your meat conveniently from a distance, right on your phone. That’s the idea behind the myriad of W-IFI meat thermometers.
WiFi Meat Thermometers are awesome. They offer more wireless range, allowing you to monitor the internal temperature of your meat from virtually anywhere in the world – if both you and your thermometer have an internet connection. But what happens when you don’t? Ever tried taking a WiFi Thermometer camping? That’s when a Bluetooth meat thermometer comes in handy.
Wi-Fi capable devices are also more expensive then stand-alone Bluetooth thermometers. We found many of our readers liked the idea of owning a Wi-Fi temp reader but didn’t always want to spend the extra money. This is what lead us on a journey to discover the best Bluetooth thermometers.
While Wi-Fi thermometers need a W-iFi signal in range, Bluetooth thermometers pair directly with your smartphone – via Bluetooth – no need for an internet connection. You can grill at the park, the beach or the campsite, without needing to carry around your WiFi router (who does that, anyway). And if your home Wi-FI doesn’t reach out to the grill well enough to work, just fire up the Bluetooth.
Bluetooth won’t have as much range as WiFi thermometer, which works through the cloud. Most devices will top out at about 150 feet – line-of-sight, at least. That number will even less when walls and doors get in the way. (Some work better through walls than others).
One or two thermometers out there might get 300 feet, such as the GrillEye. But, 150 feet should be enough to do most tasks around the kitchen or campsite or let you relax on the deck, while the meat is on the grill out back.

5 Best BLUETOOTH thermometers
#1 THERMOWORKS BLUEDOT
Our Top Pick for the best Bluetooth Thermometer on the market is the ThermWorks BlueDOT.
Compact, tough and superbly-simple, it’s the Bluetooth-enabled version of the DOT – ThermoWorks’ best alarm thermometer. Quick to setup, easy to operate and still totally-affordable, it’s got everything we want in a Bluetooth thermometer with none of the frills - and blows many cheaper alternatives out of the water in terms of quality and reliability.
What We Like
The BlueDOT is ridiculously simple. There’s a small, round display with both current and target temperatures on display, as well as backlight. On the front are two navigation buttons for setting the alarm, and on the back is a power button – and that’s it. No frills.
It’s tough and compact – IP65 rated for splash resistant and dustproofness, the DOT is built to stand up to the rigors of a commercial kitchen - so it can handle your kitchen like a champ. Just don’t try dunking it underwater or subjecting it to too much abuse.
It comes with a ThermoWorks Pro-Series probe, which has a total range from -58°F to 572°F and is accurate to within +/- 1.8°F of the actual temperature. And, it’s pretty fast – not the fastest probe we’ve used, but plenty fast enough - for everything from smoked briskets to thin steaks. Whatever you’re cooking, this probe will let you know exactly how hot it is and exactly when it’s done. The cable is roughly 4 feet long.
The ThermoWorks App is as good as it gets. It’s one of the simplest and most intuitive smart thermometer apps we’ve tried; easy and quick to navigate and set up.
You can set high and low alarms and alerts, name probes, chart your cooks with graphs, and even change how often the thermometer updates its temperature on the display. And, while the device itself can only set Max Temp alarms, the app lets you set a minimum temperature alarm, too.
The only things missing are presets for foods you cook regularly, like brisket or pork, and note-taking in the cooking graph/log area.
The big display is easy to read to at a glance. Pretty much everything you need to know is displayed, and there’s a nice 10-second backlight you can turn on or off with the press of a button. Don’t underestimate this; being able to quickly look over and see where your food stands can be mighty handy when you’re juggling multiple cooking tasks.
It runs off 2 AAA batteries – and gets a respectable 500 hours of runtime out of them. That’s not as much runtime as some of the other thermometers in our testing, but enough to do quite a quite a few all-day smokes without needing to replace the batteries. QUITE a few.
What We Don't Like
- Bluetooth range is only about 95 feet line-of-sight. Obstacles can greatly impair this, and we’d really like to see it get closer to 150 to 200 feet.
- You can’t mute it. We’d like to be able to turn off the alarm when trying to cook quietly.
- The app doesn’t have presets for foods and meats you make often.
#2 THERMOWORKS Signals
Replacing the old ThermaQ Blue is ThermoWorks Signals, which stands out from other Bluetooth thermometers thanks to its Wi-Fi capability.
It’s a lot like the BlueDOT’s big brother, but with more features – in addition to WiFi. It’s also the most expensive thermometer in our roundup. However, it holds our #1 spot for the best Wi-Fi grill thermometer, you can see the complete Signals review here (or just read below for the summery). Thus, if you don’t need the dual Wi-Fi/Bluetooth, it may be a better idea to simply choose a cheaper one like the BlueDOT or Inkbird.
It’s got both WiFi and Bluetooth. This way, you can use it both at home and in places where WiFi isn’t available – like the campsite. You can switch between them seamlessly, too, just by toggling one on/off on your phone. Bluetooth range is roughly 95 feet.
It comes with 4 Pro-Series probes.
These thermistor probes have a range from -58°F to 572°F and are accurate to within +/- 1.8°F. Our testing found them right on the money. Being equipped with four probe channels gives you enough flexibility to monitor multiple roasts or pit temps simultaneously, and the Signals works with a wide array of probes from Thermoworks and other manufacturers alike.
The body is IP66-rated, meaning its dust-resistant and splashproof. The build is also totally rock solid and insanely durable, built for the rigors of the commercial kitchen but just as at home on your back grill.
The display is large and easy to read to at a glance. Everything you need to know is always displayed right in front, and there’s no need to scroll through to turn certain features on or off. It’s also got a bright backlight that can be toggled of/off.
It stands up on its own. You can place it firmly on the countertop or grill side table or use the two magnets on the back for mounting to your grill, oven, or fridge.
Navigating and using are insanely easy. All the controls you need are located right on the front - including navigation, backlight and volume.
The rechargeable battery lasts 16 hours on a single charge. It recharges via an unusual USB-C cable.
The app is ridiculously easy to use. Everything is straightforward, but it’s also packed with all the features you need – like alarms and cooking graphs. You can even change how often the temperature refreshes. Setup is quick and painless, unlike many other thermometers.
- Bluetooth Range is limited. We’d like to get more than 95 feet – and some other Bluetooth Thermometers can.
- It’s expensive. Like we said earlier, there are much cheaper options to choose from – unless you just like the idea of having Wi-Fi.
- The probe connectors melt at high temperatures. ThermoWorks rates them for about 700°F - so way more than your typical 225°F pit but not much hotter than a searing hot grill.
- You can’t mute the buttons. You can mute alarms, but the navigation buttons on the front will always beep.
#3 Inkbird ibt-4xs
Our favorite Bluetooth thermometer before we tried the BlueDOT the Inkbird rolls ease-of-use, durability, and price into a convenient package.
The IBT-4XS is a wireless Bluetooth meat thermometer with four probe channels and compatibility with both iOs and Android phones, meant for grilling and smoking, as well as cooking or baking in the kitchen. It is smart, capable, and easy-to-use.
Inkbird reached out to us and asked if we would like to test out and review the IBT-4XS for them. While we knew they were a manufacture of temperature controllers we had our reservations of how well it would preform when grilling or smoking.
The Inkbird IBT-4XS comes neatly packaged in small, but surprisingly high-quality, brown cardboard box, that gives it a quality feeling superior to most devices in a similar price range. When you open it, you first see the device itself seated in plastic, and underneath will find 4 temperature probes, a USB charging cable, 2 metal probe clips for keeping them placed securely in the meat, and an instruction manual. Each of the temperature probes comes individually wrapped in plastic, with the cables neatly coiled, and a rubber cap protecting the pointed ends.
The device is small and sharp-looking and features only two buttons – an On/Off switch on the bottom and a touch-button on the front screen (kind of like the touch-button found on newer iPhone models). On the front, you’ll also find the 4 ports for attaching the meat probes, and on the back, a micro USB port for charging.
Upon turning the Inkbird on, you will see the current temperature reading (if any) displayed on the front in large red font, a probe indicator, battery level, Bluetooth indicator if your phone is paired, and a temperature unit display (C or F). You can even rotate the display by tapping the Power/Pairing button twice.
The Inkbird Thermometer has magnets on the back as well, so you can mount the device easily to the side of your grill or oven if you’re cooking inside. And they’re actually quite heavy-duty magnets; the device feels secure and shouldn’t go anywhere, freeing up some space on the counter.
The Inkbird IBT-4XS runs off a 1000 MAH Lithium-Ion battery, which is charged via Micro USB. A USB charging cable is included, and Inkbird really talks up the 1.64 ft length in their marketing materials. Personally, I wish the cable was longer; it’s just a bit too short to charge comfortably on a wall outlet. The battery is supposed to last up to 60 hours of use, but we haven’t had a chance to try that just; the device will go into a sort of sleep mode if left on with no input from a probe. Charging the device fully takes about two hours, and you can’t charge it while it’s turned on and monitoring meat.
Pairing the device to your phone via Bluetooth is exceedingly simple:
- Download the BBQ Go App from the App Store
- Turn your phone’s Bluetooth on
- Follow the instructions in the app – which is as easy as simply pressing the Connect button while the light is flashing.
The app recognized the device right away, and it took about 2 seconds to connect. In the future, your phone and the thermometer will automatically pair when you have the app open, so you can just fire up and go.
It works with both iOS and Android smartphones.
Inkbird says the device has a range of up to 150 feet, and while we didn't measure distance exactly, that appeared to be about right when taking a short walk away from the grill. That should be more than enough distance to head into the kitchen while the food is on the grill or smoker - unless you have a very large yard or live in an apartment complex (like some of us do). In which case we would recommend selecting one of these WIFI thermometers.
Now for the part we've all been waiting for. Here's where most of the previous bluetooth devices we reviewed fall short – after all, you're only as good as data you receive.
When you open the app, you will see four different temperatures displayed – one for each of the four probes. There’s a selection of presets you can choose from – such as Beef, Chicken, Pork, Hot Smoke, etc – and several preset temperatures for each, e.g. Rare (125F), Medium-Rare (130F), and so on. You can delete these presets, customize them, and add your own temperature settings.
Each probe can be set differently, and you can set both timers and desired temperatures for each one; the app will alert you either when the temperature is reached, or the timer is up. You can even choose different colors for each of the probes to help keep track of them.
The small round icon (shown in the previous screenshots) keeps track of the progress of the meat as it gets closer to it’s target temperature.
At the top, there is also a menu that displays current Firmware version, lets you toggle between F and C as your preferred mode of temperature display, as well as turn off notifications if the device and phone become disconnected (out of range, dead battery, etc). You can set an Alarm Interval for repeating temperature alarms for the same probe and enable or disable the alarm ringtone or vibration. You can even change the language to German, Spanish, Italian, French or even Dutch.
Lastly, there is a Temperature Graph function, which lets you keep track of your grill and smoke sessions in a handy chart.
Overall, it shows that this device was manufactured by a company with experience in home automation technology. The entire app interface is very simple and easy to use and should have you out on the grill with little in the way of setup.
Where the rubber [meats] the road: Putting the inkbird to use
So how does it fare on the grill? To test the Inkbird IBT-4XS out, we fired up the grill and threw on some top sirloin steak (but not before seasoning them with gratuitous amounts of salt and pepper). Inserting the probes was as easy as it should be; the probes are about 5” long, which makes them perfect for sliding into the center of a thick steak and still large enough for larger pieces of meat such as brisket or a whole chicken. Be methodical when inserting though; the probe poked through the side of one of our steaks, giving an inaccurate temperature reading and saying it was done long before the center of the steak had reached the desire temperature. (That goes all for thermometers and meats, of course).
The probe cables are about 4.9 feet long each, which is great when using very large grills and smokers where your thermometer needs to be far away from the heat.
For regular grilling, however, we found that they are just too long, and tangle with each other easily, especially when flipping the steaks. This would be less of an issue when smoking for long periods of time but was quite frustrating. There isn’t necessarily much any thermometer could do to prevent this issue, but some kind of cordwrap, or organizer would be nice.
The quality of the braided cables, however, seems more than adequate for a thermometer in this price range.
Included in the package are two metal clips in the same style as many other meat thermometers. These clips can be used to mount the probes to the grill and take its ambient temperature reading. Doing so is very simple and gave a steady reading that matched the grill’s own.
With the temperature probes firmly planted in the thickest part of the steak, the Inkbird gave us a pretty accurate internal temperature; Inkbird says it’s accurate to +/- 2F, and using a regular kitchen meat thermometer to judge, we’d say that’s pretty accurate.
We set each the probes in each of our steaks to the Beef preset, to a 120F Rare. We had a few problems getting the readings right on our first steak, as the probe was not correctly inserted and was poking out the other side into the grill. The IBT-4XS promptly let us know that the steak was well-overdone, flashing and buzzing until we removed the steak and fixed the probe. From there it was relative smooth grilling.
For some reason, however, the device only alerted us when one of the steaks had reached its desired temperature of 120F. While my phone vibrated and the device itself beeped quite loudly with that steak, it was completely silent when the second steak reached 120F, even letting the temperature creep past the target. After playing with the settings, we couldn’t figure out whether this was human error or a glitch, but after testing out the device a few more times, we couldn't recreate this issue. Perhaps there was a setting we had forgotten to customize.
And how did the steaks turn out? Upon removing them from the heat and letting them sit for several minutes, we sliced into some perfectly rare steaks – seared on the outside but still juicy and red all the way through.
Seeing as how easy it is to overdo steak – getting it a bit too late and eating it medium or medium-well – Inkbird does its job.
- It can handle up to 4 probes at once, with 4 prone channels. 4 food probes are included, as well as two clips for mounting some of the probes as ambient probes to monitor the grill temperature. The probes are accurate within +/- 1F of the true temperature and work very well. The probe cables are also very long – 4.9 feet each. That makes working with them on the grill easy (but also makes them hard to store neatly, which we’ll get to).
- Temperature range is from 32F to 572F – more than enough for most smoking and grilling jobs.
- The device itself is compact and durable. You can fit the thermometer in your hand and it feels well put-together. On the back are magnets for mounting to the side of the grill or even the fridge.
On that note, the probe cables are also durable, made of braided metal cable. We have no reservations on their ability to withstand heavy use.
- It runs off an internal 1000Mah Li-ion battery, which can be charged via Micro USB. The battery is rated to last 60 hours of use – more than enough for several grilling sessions, or even several long smoking sessions. It also comes with a 1.64-foot-long Micro USB charging cable (Inkbird is very particular about that range, for some reason…)
- Bluetooth range is 150 feet. We find the Inkbird really does get about that much range, even with some walls and doors in the way. And 150 feet of range put it squarely in typical territory for Bluetooth thermometers, as almost all of them get that much range.
- The app is super easy to setup, intuitive to use, and displays all four probe temps at once. There’s a host of smart features available, and you can set min/max temperatures for each piece of meat individually. There’s also a whole host of preset options to choose from (Beef, Chicken, Hot Smoke, etc) and you can customize each of these presets precisely to your liking.
- When the target temperature is reached, the app will let you know – setting off an alarm that rings and vibrates your phone – quite loudly – until you turn it off and attend to your meat.
- And, don’t forget the graphs and logs. Want to see exactly how long it took to that piece of meat, and how hot the temperature got and when? The app will let you do that. You can even export them via .csv to archive and learn from later.
- There’s a 12-month warranty. Inkbird believes in their product and wants you to, too – and to be totally confident in using it.
Yeah, there are a few things we don’t like. These include…
- The body is not waterproof or weatherproof. When you’re planning on leaving your thermometer outside all day while smoking a massive piece of meat, it’s nice to not have to worry about it getting wet from unexpected rain or thunderstorms. It’s also nice to have it protected against splashing grease and water when cooking. That would be a welcome improvement.
- The Cables are long, but hard to wind up. They get tangled easily when cooking with several of them at once. It’s great to have this extra length when you’re doing a lot smoking on a huge pit, but the extra length is a bit frustrating when you’re not. And there’s no convenient way to wind them up.
- The probes are not color-coded. This would be a huge, welcome addition to the kit – and many others – and would make telling the difference between probes so much easier. As it stands, there’s no way to tell which probeis which while it’s on the grill and when you’re glancing at your phone from inside the kitchen.
For the price, the Inkbird IBT-4XS provides an excellent value for a wireless Bluetooth meat thermometer. Most grilling fanatics and amateur smokers may never need the quality, features and robustness of the more expensive thermometers out there (like our #1 overall pick in wireless thermometers The Fireboard). In that case, the InkBird fits the bill perfectly. It’s easy to setup and use, it reads temperatures quite accurately, and while not bombproof, is well-built and durable enough for everyday use.
There are a few things we would like to see, such as weatherproofing and impact-resistance. And the cables are a bit long, becoming easily tangled when dealing with multiple pieces of meat. It would also be nice to have some kind of color coding so you can more easily keep track of which probe is plugged into which port at a glance. You can set different colors for each probe on the app, but there is nothing included to mark the physical probes.
For the price, however, the Inkbird IBT-4XS is a solid meat thermometer. While there are other similar Bluetooth thermometers available at comparable prices, the Inkbird offers more probes than most, and has a much simpler interface.
Overall, the Inkbird IBX4S is a solid Bluetooth meat thermometer. It’s durable, quality and compact. The temperature probes are accurate and consistent. The internal battery is powerful and easy to charge, with a long life of 60 hours. Inkbird offers more probes than most, and the user friendly app provides a whole host of features. It’s also reasonably-priced, making it the benchmark to which we compare the other top Bluetooth thermometers.
The IGrill2 is a compact, stylish Bluetooth thermometer that tends to fly under the radar but packs a punch in its small size and mid-range price. It’s a great device with plenty of features, accurate temp readings and 4 probe channels. Our only complaints are that Bluetooth signal is sometimes weak and the build isn’t as heavy-duty as we would like.
- It’s compact. Only about 2” by 2”, it fits in the palm of your hand and weighs practically nothing.
- It works with up to 4 probes at once. That’s as many as the Inkbird and the Signals, and 3 more than the BlueDOT. It comes with two meat probes, which IDevices touts as “pro-level” and ready to withstand high temperatures and steam. You can purchase an optional ambient probe and clip, as well as more meat probes, for a full setup. Probes cables are 48” long.
- The Probes are consistent and accurate. IDevices says they’re correct up to within 1 degree of true temperature. Tests have proven that accurate.
- Bluetooth range tops out at 150 feet. This competes with virtually every other Bluetooth thermometer in this price range, and is 50% more than the #1 BlueDot. The Bluetooth signal is consistent, unlike a lot of cheaper options.
- The app has preset and custom settings for alarms and alerts. The Minimum possible temperature you can set is -22F, while the maximum is 572F. Alarms and alerts pop up on your phone, and you can of course create cooking logs and graphs and export them as spreadsheets. The app is available for both iOs and Android.
- The app can pair to more than one iGrill at once. This is handy if you’re having a super-big-BBQ, and want to use more than 4 probes simultaneously.
- There are magnets on the back panel for mounting. You can stick it on the side of your grill, on the fridge – anywhere metallic that is convenient for you while you grill.
- Battery life is touted as 200 hours. While that’s not nearly as much as the ThermaQ’s 4000, it’s more than enough for most of us. You’ll get many grilling sessions out of the 2 AA batteries included. Auto Shut Off turns it off after a period of inactivity, preserving that battery life and ensuring you get 200 hours of good use.
- Battery life is touted as 200 hours. While still beaten out by the BlueDOT’s 500, 200 hours more than enough for most of us. You’ll get many grilling sessions out of just the 2 AA batteries included. Auto Shut Off turns it off after a period of inactivity, preserving that battery life for max use.
- The illuminated display on the front makes reading the probes at a glance, easy.
- The Bluetooth doesn’t go through walls. Yes, range is 150 feet – but that’s with a clear line of sight and no obstructions. Try walking around the house while the thermometer is attached to the grill, and you’ll have some issues.
- The body is not the most durable. Compared to other thermometers – the BlueDOT and Inkbird, especially – the IGrill 2 feels cheap and lightweight and we’ve heard from some people that it doesn’t hold well over the long run.
Overall, it’s another great device with a lot of capability and features, accurate readings and 4 probe channels. But the Bluetooth signal can be weak, and the build isn’t as heavy-duty as we would like.
Looking for a Bluetooth thermometer with some serious range? Perhaps you’re looking for the GrillEye, with its impressive 300’ foot Bluetooth range – twice what any other thermometer offers. It takes up to 6 probes at once - though it’s not the most accurate at reading temperatures. The build also feels cheap and flimsy, knocking it down to last place on the list.
- The GrillEye has 6 probe ports, allowing you to monitor quite a bit of meat at once, and mix in an ambient probe or two. Two meat probes are included with the package, as are two ambient probes.
- GrillEye probes are FDA-certified for use with food. Made with space-grade aluminum, they’re the first in the world to claim that honor. We’re not exactly sure what benefit that lends over non-certified probes, but it certainly sounds cool.
- The LED screen shows two temperature readings – target and current. The screen is coated in an anti-glare polymer coating reflects sunlight and keeps things easy to read. It’s actually quite glossy and stylish to look at in person.
- The body is compact, lightweight, yet durable. An adjustable stand, made of space-grade aluminum, lets you determine its angle and height so you can stand it up and read it easily.
- The GrillEye app lets you set target temperatures and alarms, and both sound and vibration will go off. It essentially uses the same app as the Firebird and other devices, meaning you have all the same functionality – charts, graphs, logs, etc.
- Bluetooth range is up to 300 feet. This is twice what any other thermometer offers, three times what the BlueDOT is capable of, and easily the GrillEye’s main selling point. The Bluetooth signal is strong, consistent and works through walls – though those will affect the overall total range.
- The probes are not consistent or accurate. They tend to be off and sometimes they even wildly fluctuate – showing as far as 34F off what they should be. This discrepancy is even noted in the documentation, and surprising for a meat thermometer of any quality. It’s a great way to accidentally ruin some chicken or expensive steak.
- The build quality really could be better. The device looks great, as we mentioned, but it just doesn’t hold up the way we’d expect from a thermometer this expensive. It’s also not waterproof, which would be most welcome and boost our opinion of this thermometer significantly.
Overall, we like the GrillEye. It has powerful Bluetooth capabilities and range and can work with up to 6 probes at once. But it’s not accurate in its temperature readings, and the build feels cheap and flimsy, which knock it a bit lower down the list.
Buyer's guide to bluetooth meat THERMOMETERS
What To Look For When Choosing A Device For Your Meat
What exactly are you looking for when choosing a Bluetooth meat thermometer? Ask yourself these questions when looking at your next device….
How Many Probes/Channels Does It Have? Are There Ambient Probes?
This should probably be your main consideration. How many probe channels does the thermometer have, and how many probes does it come with? Most will come with about 4 probe channels. Ideally – if you do a lot of grilling – you’ll have about 6, so you can monitor several pieces of meat and the pit temperature. Some thermometers, on the other hand, only have 2 channels.
How Consistent and Accurate Are The Probes?
Most thermometer devices come with high-quality probes (Thermistors or RTD probes) that are very accurate, often within +/- 1F of the true temperature. Others…not so much. Many probes are just inconsistent and poor, and will report widely swinging, inaccurate temperatures – sometimes as much as 30 or 50 degrees off! Be sure to read some reviews and make sure the device you pick has reliable, quality probes that will report the right temperature and prevent ruining your brisket by accident.
How Much Range Does It Get? How Strong is the Bluetooth?
Most Bluetooth thermometers offer about 150 feet of range, line-of-sight, meaning that walls and other obstructions will severely affect the range. A few devices – such as the Inkbird – have stronger signals that we find are less affected by walls, while others get even less than the advertised 150 feet. A few devices boast ranges of 300’.
How Smart Is It?
You wouldn’t be getting a Bluetooth thermometer if it weren’t for the smart features and the app. Most thermometer apps will have a variety of presets for different meats (Steak, BBQ, Chicken, Pork) that can all be customized to your own definition of “Medium-Rare.” They’ll all have minimum and maximum temperatures you can set, and alerts, alarms and notifications that pop up on your phone when those temperatures are reached.
And, most will also have cooking graphs and charts, so you can create logs of your smoking and grilling sessions, see what went wrong, and export them to go over later. Some even let you share these logs with your grilling buddies on social media!
Nobody wants their thermometer to die while the meat is on the grill. Make sure the device gets good battery life, and that the battery (or two) can be easily recharged or replaced. Some devices even claim to get 3000 hours of life off two AA’s….
