Designed for serious BBQ and all-day smoking sessions, RFX is built to stay reliable when other wireless probes drop out. Set alerts, track your cook in real time, and let the brisket run undisturbed — no hovering over the grill, no lost connection. Whether you're smoking pork shoulder overnight or managing ribs from inside the house, RFX gives you the confidence to step away without sacrificing control.

Built on patent-pending sub-GHz radio frequency technology, RFX maintains a stable connection up to 1,500 feet line of sight — without the range limits of Bluetooth®. Four independently calibrated sensors deliver ±0.9°F accuracy across critical cooking ranges, while the RFX MEAT™ probe withstands external heat up to 1,000°F and runs up to 52 hours on a quick charge. The RFX GATEWAY™ sends continuous data to the ThermoWorks app via Wi-Fi or Bluetooth, so you can monitor, review cook history, and hit precise doneness every time.

Everything you need to get started: RFX GATEWAY™ (receiver), RFX MEAT™ (wireless probe), Pro-Series® Air Probe (ambient temperature), grate clip, charging block, power adapter, USB cable, and probe rings.

  • Long-Range RF Connection: Patent-pending sub-GHz radio frequency technology maintains a stable connection up to 1,500 ft line of sight.
  • Designed for Unattended Cooks: Maintains consistent temperature data during long cooks without the dropouts common to Bluetooth®.

Reviews

Great wireless thermometer, clunky app

"I tried several different brands of wireless thermometers, and this is by far the best. Great signal strength, accuracy and battery life. The only thing holding it back is the clunky app. It works well enough to use, but it could be improved upon. The Apple Watch app is also completely useless."

— Kurt M. (4/5)

Love the RFX

"I already own 2 thermopens, and a “signals” unit. All of these ThermoWorks products are great. The RFX is a game changer! Easy set up, easy to use and accurate. I’ve already added more probes to my starter kit. I use it at home and when I volunteer to cook for veterans organizations raising money to support our vets! I’m a loyal ThermoWorks customer!!!"

— No L. (5/5)

Great design and engineering

"Just received and tested. The title says it all. 2.4MHz WiFi channel is an excellent idea to maximize transmission distance and penetration. My only negative comment is that the little Lifesaver candies don’t have any flavor. And they’re chewy. But it was a cute thought."

— Elliot (5/5)

Replaced my ThermaQ Blue with

"Replaced my ThermaQ Blue with the RFX system as I needed probes for cooking meat on the rotisserie. Works very well. I will also use additional probes for smoking a brisket at the same time as a chicken is on the rotisserie. Also, the probes work well for calibrating our oven. Just insert the probe into a sponge and place in a covered ceramic casserole dish filled halfway with water."

— Dan W. (5/5)

Phenomenal thermometers for asymmetric cooking.

"These were a game changer for me doing large sessions on the smoker with different cuts going at the same time. Now I dont have to constantly open the door to probe everything. The app is clean and concise. Being able to set temp alarms for each individual probe along with the air temp probe takes alot of stress out of long overnight cooks. Custom alarms wake me up in the event of a flame out so I can fix it ASAP. No more waking up to a stone cold smoker with undercooked meat."

— Jake (5/5)

IT'S THE PRODUCT I WAS WAITING FOR

"I've had my RFX 3 probe system for several years now & it's the best product I've used bar none! I use it cooking everything on the smoker, grill or in the oven. I've been a smoker enthusiast for 40 years and have trusted the quality of ThermoWorks for years now. The recent purchase of the RFX 1 probe and the RFX 2 probe kits are birthday / Christmas gifts for my kids who got the smoking bug from me. Gave 'em Thermopen Ones when it came out. I think I bought 5 of them for family and friends. The RFX MEAT probes will make great gifts! Now about the NANO!"

— Bill O. (5/5)

Nest probes I've used.

"I purchased these back in June for a long overnight smoke on several briskets. I've had wired probes and other wireless probes by several other manufacturers. The RFX probes are option packed, stay connected and are accurate as all get out. I don't use them every time I cook but when I do I have no trouble with connecting. The probes are charged by a AAA battery, in the base and the batteries last a long time. The gateway is rechargeable and has held a full charge for several months of non use. The gateway and probe charging bases have magnets are store conveniently on the side of my refrigerator."

— Butch (5/5)

PERFECT MINI SIZE

"The mini RFX probe is perfect for smaller cuts of meat. You don’t have to worry about burning out the probe or it coming out the other side. Great for Filet and Tri-tip. It also reports temp to the app really quick. HIGHLY RECOMMEND."

— Dally (5/5)

The range is incredible; it

"The range is incredible; it easily maintains a connection from several dozen meters away, even through a metal smokehouse. It’s a real shame, though, that it doesn’t measure the ambient temperature like some other sensors, such as the Meater."

— Marcin K. (5/5)

Exactitude

"I used my RFX gateway for the first time. Smoked four chicken legs on a Kamado at 225 followed by a reverse sear. It took less than 25 minutes from the first charcoal ignition to a stable Kamado temp that didn’t vary over 1.5 degrees during 45 minutes of low temp cooking. My probe which looked way too long for the thigh in which it was inserted worked perfectly as checked with my thermopen. Those four temperature points found the middle despise the fact that the tip was near the end of the thigh. And this is my first cook. I can only imagine how pleased I’ll be when I refine things with experience."

Q&A

Does this come with a NIST Certificate (Like your Explore Thermapen NANO does) for each probe?
Each RFX MEAT™ probe does comes with its own NIST-traceable calibration certificate.
Does the starter kit include a charging block for the probe?
Yes, each probe in the starter kit will include a charging block.
Can the RFX probe be used for baked goods?
Yes. As long as you submerge the probe up to the minimum immersion line in your food, RFX is is a great way to monitor baked goods in your oven.
Does the RFX communicate through aluminum foil in a smoker? When I smoke pulled pork, the last stage is in a foil pan covered and sealed with foil and another cheap probe I purchased lost communication.
Aluminum foil can block wireless signals if the probe is completely sealed inside! RFX uses powerful sub-GHz radio frequencies to pierce through obstacles, but for the best results when wrapping pulled pork, make sure the end of the probe pokes slightly outside of the foil wrap. Leaving that end exposed inside the smoker chamber ensures your RFX Gateway maintains a rock-solid connection all the way through.
Can the RFX™ Wireless Probe Starter Kit software operate a Billows fan?
Yes, RFX GATEWAY can operate a Billows fan controller.
