Designed for professional kitchens and food service environments, RFX delivers continuous remote temperature monitoring across extended cooks. Wireless probes track internal temperatures in real time so teams can verify doneness, maintain consistency, and protect food safety without interrupting service. Built on patent-pending sub-GHz radio frequency technology, RFX maintains a stable probe-to-gateway connection across kitchens, smokers, ovens, and production spaces—without the dropouts common to Bluetooth®.

Each gateway supports 50+ probes and sends continuous data to the ThermoWorks app and cloud for visibility across multiple cooks simultaneously. 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 50+ hours on a single charge. Whether monitoring briskets in a BBQ pit, verifying pasteurization in cook-chill systems, or tracking temperatures through conveyor ovens, RFX provides reliable, real-time data to support operational efficiency, consistency, and food safety compliance.
  • Monitor Multiple Cooks in Real Time: RFX Gateway supports 50+ probes to track multiple cuts, batches, or cooking stations simultaneously.
  • Stable Long-Range Wireless Signal: Patent-pending sub-GHz RF maintains a dependable probe-to-gateway connection across kitchens, smokers, and large production spaces.
  • Reliable Where Bluetooth Falls Short: Sub-GHz RF penetrates walls, ovens, and equipment where Bluetooth probes often lose signal.
  • Follow Temperatures Across the Entire Cook: Four independently calibrated internal sensors monitor temperature changes along the probe length for clearer insight into doneness and product consistency.
  • Verify Critical Control Points: ±0.9°F accuracy supports HACCP programs and helps confirm critical cooking and pasteurization temperatures.
  • Built for High-Heat Cooking Environments: Probe withstands external temperatures up to 1,000°F for grills, rotisseries, smokers, and high-temperature ovens.
  • Designed for Extended Production Cooks: 65+ hours of battery life supports overnight smoking, large batch cooking, and long production runs.
  • Remote Tracking Through App and Cloud: RFX Gateway sends real-time data to the ThermoWorks app and cloud via Wi-Fi or Bluetooth for alerts, logs, and cook history.

RFX Gateway

RFX MEAT

The RFX system abandons unreliable Bluetooth in favor of our patent-pending Sub-1 GHz radio frequency. Engineered for uncompromising durability, this professional-grade technology effortlessly pushes signals through thick steel smokers, heavy dutch ovens, and commercial oven walls. By prioritizing signal density over novelty, RFX delivers the most stable, uninterrupted wireless thermal data available for precision cooking.
The RFX Meat Probe captures internal temperatures and transmits them via our patent-pending Sub-1 GHz RF technology directly to the RFX Gateway. Acting as a powerful bridge, the gateway instantly processes that raw thermal data and pushes it over Wi-Fi or Bluetooth to the ThermoWorks App, ensuring your cooks are monitored with exacting, continuous reliability.
The RFX probe transmits temperature data up to a commanding 1,500 feet line-of-sight directly to the gateway. Once the gateway connects to your local Wi-Fi network, your monitoring range becomes infinite. This robust architecture ensures you can track your cooks with absolute certainty from anywhere in the world via the cloud-connected ThermoWorks App.
Absolutely. The RFX ecosystem is engineered with a grounded, long-term vision, designed to grow alongside your culinary needs. The current RFX Gateway acts as the central hub for a future-proof mesh network, preparing your setup to seamlessly integrate a growing lineup of specialized ThermoWorks probes, and sensors without forced obsolescence.
Traditional Bluetooth thermometers hit a strict hardware bottleneck, capping out at just four connections. By utilizing our proprietary Sub-1 GHz RF technology, the RFX Gateway bypasses these consumer limitations, effortlessly managing up to 50 independent probes simultaneously. This purpose-driven capability allows professional kitchens and pitmasters to scale operations with absolute confidence.

Reviews

Best service!

"I’ve had some difficulty getting all things correct with my RFX……. but…. since the customer service is awesome, I’ve been able to sue this unit excellently. I have a problem with the Meat and got it worked out and bought a second one too. Appreciate the quality of product and seervice from Thermoworks!"

Best Wireless Thermometer

"I spent some time reviewing different wireless thermometers when I bought one (Chef IQ Sense) last year and was not happy with it because it always lost connection. When reading reviews online it seems that's what a lot of these type of thermometers have in common. I was watching Mad Scientist Barbecue with Jeremy Yoder and he was using the RFX system. Clicked on his link and went to the website. I liked what I saw and decided to spend the extra money to get a 2 probe starter pack. I've used it once so far for grilling steak. Never lost connection once. The old one I had bought would've lost connection at least 3x. I love how the probes charge separately from the unit transmitting the temps. I'm looking forward to future cooks."

— Albert H. (5/5)

Works super well. Great battery life.

"First, I had problems syncing the system to my account due to old account issues. The customer service team fixed it immediately and it didn't slow me down at all. Amazing customer service. Second, the wireless performance is amazing. I tossed these in my Weber kettle and smoky mountain and the readings are rock solid. Battery lasts forever. Love the magnetic charging pods, makes storage super easy. The only thing I feel is missing is a wireless ambient probe. It's not a make or break thing since I'm usually smoking with Billows and need the wire there anyway. But it would be pretty nice to not have any wires going into my smoker. Anyway, 10/10 will buy again."

awesome

"just did my first cook with it and i compared readings with mybuilt in air temp thermometer, the thermoworks rfx, and fireboard 2 drive. built in varied 15 -30 degrees off of the other 2. but the rfx and fireboard stayed within .5 degrees of each other. The reason i bought the RFX is i am tired of probes failing mid cook and having to buy new probes all the time. i have spent more money on probes then i did on the unit. the rfx works awesome and what i thought was interesting it would be the first everytime with a change in temp. I cook alot of meat for charity and if the rfx is as reliable as my thermopen one is then i will save a fortune. i got it when it first came out"

RFX Wireless Probe

"Only used it once, but it works great. Will not over cook those steaks again. Gave it 4 stars as initial set video didn’t match the current software version on the device resulting in a bit of trial and error getting everything pared. Didn’t help I waited until I was ready to put the steaks on the grill to set up. Another great Thermoworks product in my tool kit."

"Love mine so got one for each member of the family!"

RFX Wireless Probe is great

"Recently purchased the RFX Wireless Probe Starter Kit. I have cooked fish twice using the probes. The RFX is easy to set up and allows me to set temps in the app to alert me when I have different sizes of fish, yet allowing each to cook to the perfect temp. The RFX range and signal strength is excellent. I can monitor the cooking temps with my fish on the grill while I am in the kitchen getting the rest of the meal ready."

— Gordon S. (5/5)

Nice unit

"This is replacing a different brand. Just finished my first overnight cook and it performed great. Minor learning curve. . . very satisfied!"

— clay b. (5/5)

IMO better than chefs temp!

"I bought the RFX gateway along with the the billows fan to run my old country gravity smoker. I previously had a chef’s temp S1 temp and breezo fan. I noticed that the digital temp probe on the chef’s temp was not accurate, and the breezo fan would blow right by my set temperature. I’ve been through 2 breezo fans and currently have another one sitting in an unopened box. I guess it’s the algorithm or the probe that keeps my temps rock solid with the rfx system. Hopefully it lasts!"

— Edward W. (5/5)

Rfx

"The rfx has really been a solid performer for me. Ive only had it for about 2 weeks but was utilized for brisket, pork butt, country ribs, steaks and smoked meatloaf. I have nothing bad to say about the rfx and am happy I purchased it."

— Scott C. (5/5)
