Range-Extending Booster

More power

This CPT accessory boosts signal strength and allows you to recharge your Predictive Thermometer even when you don’t have access to USB power.

Perfect for smoking, grilling or other outdoor cooking - the Booster helps you overcome radio obstacles like thick-walled metal smokers and grills. Use the Booster as a relay station, while you control settings and observe temps from far away with the Combustion Display or App.


You can even “daisy-chain” other MeatNet devices (like the Display) as relay “hops” to cast a signal even farther. The CPT + Booster + Display + App can reach up to 1000ft! (300m!)

Cordless recharge

The Booster’s onboard battery has enough juice to recharge your Predictive Thermometer fully up to 8 times. When stored in the Booster, a Predictive Thermometer will stay fully charged and ready-to-go for up to 6 months.

Stay ready so you don’t have to get ready!

30-day trial

2-year warranty

We’re confident that the Predictive Thermometer will become one of your trusted cooking tools. If you’re not absolutely in love after 30 days, send it back, no questions asked.

What’s it all about?

It's a range-extending cordless power station for the Combustion Predictive Thermometer

Extends range up to an additional 330ft(100m). Use the Booster to overcome radio obstacles like metal grills and smokers, walls, ovens, whatever. Place the Booster beside your cooking area and it will relay the signal to where you are (well, pretty darn far anyway).

Incredibly simple to use

Just turn it on and let it do its thing. The Booster will relay any and all signals from any MeatNet device. There's no set-up or passwords or any of that - it just works. Still works when the internet is down.

Stay ready always

Nestled in the Booster, your Predictive Thermometer can stay ready (in standby) for over 6 months.

Camping and Cookouts and Weekends Oh My

With the Booster, you don't need wall power to recharge your thermometer - the onboard battery can do that lickity-split (well, in about 20 minutes depending on how much it needs).

iOS and Android apps 

The Booster relays signals to and from the Combustion App so you can monitor and control your Predictive Thermometer from your phone or device.

Also works with the Combustion Display

Booster works with the Combustion Display to extend potential range up to 1000ft total!

All orders are shipped in the order received. 

It takes 1-3 business days to process orders and get them on their way. At that point, you'll get a shipping confirmation email. Shipped!

In periods of very high demand, products may be temporarily back ordered while we are waiting for inventory to arrive.

In that case, the estimated ship date will be listed in checkout (for example “ESD: Aug 21, 2023”) - that’s when your order is expected to arrive at our US warehouse for delivery shipping + handling.

When it arrives depends on the shipping method, location and (for international orders) customs inspections and other random events. 

Domestic shipping

Prices and shipping options are listed in checkout. (Don't use the fast delivery options for products that are back-ordered! It won't help much in that case.)

Worldwide shipping

No surprises! We ship to most countries Delivered Duties Paid (DDP). That means everything-taxes, duties, import fees, and shipping fees-are calculated and pre-paid at check-out.


Can it be used in a ____?

If you can cook meat in it, then almost certainly yes. Grills, smokers, ovens, ranges, pans, induction, air-fryers, rotisseries, slow-cookers? All good.

Microwaves are no-go. Sorry, Sparky.

The handle is safe up to 600ºF. The internal components are good just above 220ºF, but don’t worry: they’re insulated by the food while it cooks.

How’s it different from other wireless thermometers?

8 sensors. Competing wireless thermometers have 2 (at most!).

Those “extra” sensors are a huge advantage for you. They create context so we can figure out the effective size of the food, how evenly it’s cooking, and exactly how things are changing. This leads to more accurate predictions. More data equals less guessing.

By comparing temps at each sensor, we can find the lowest internal temperature every time, even when you miss the “center.” We’ve all done that, because most of the things we cook aren’t a uniform block. That doesn’t matter with the Predictive Thermometer.

The extra sensors also allow us to locate and measure the surface temperature.

If you want more consistent results from your favorite recipes, keep reading.

What’s special about surface temperature measurement?

Surface temperature is the secret to consistent, precision cooking. That's because the temp at the surface of your food is the temperature the rest of the food feels.

It's nowhere near as hot as the surrounding oven. That's because your food sweats. As it does, the evaporating juices cool the surface. How much? Depends on the food. That's why we measure at the surface. And by the way, we’re the only one who can.

By measuring surface temp, you can adjust your oven or smoker to control the true cooking temp, bringing a level of precision to your cooking usually only possible with sous vide.

Why Bluetooth?

The newest Bluetooth standards gives us the strongest possible signal, and it’s far more consistent than WiFi. No dead spots.

Secondly, there’s no “handshake” problem. A WiFi router requires sign-in every time you start up (or restart) a device (sometimes it happens automatically, but not always). That’s the last thing you need when your pork chops are in the oven.

The way we have it set up, it’s no hassle. If the thermometer is on, it’s broadcasting. If the display (or your mobile) is on, it’s receiving that broadcast. It’s just simpler that way. You shouldn’t need tech support to cook a ribeye.

Can I hack it?

Yes. Easily. All the temperature data is broadcast in the open, where you can grab it with any Bluetooth device. We use an open standard so clever dev-type people can make their own apps.

It’s impossible to build an app that’s all things for all cooks. We know folks will want specialty apps more suited to certain styles of cooking, and that’s great. Go hog wild! Our stuff is free to build on, and what you build remains yours.

Open standards also mean the Predictive Thermometer will be able to work with many smart appliances. It can be the “eyes” of a connected kitchen, telling appliances what they need to know so they can (for instance) adjust the heat level when needed.

Hello. We’re Combustion Inc.
We build nice things that make cooking enjoyable.

You don’t need much to prepare a great meal: A sharp knife (like actually sharp), a few good pans, and a modest assortment of other tools are enough. You should definitely have a good digital thermometer. And we think it should be smart enough to take the guesswork out of cooking. We made ours that way, so that your food will be just right, every time.
