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 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."

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."

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)

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)

Took a couple of years to talk myself into it

"Netter than expected, bought the four probe kit thinking I'd pprobably only use one of two at the most, wrong. Second cook and all four were in action monitoring a batch of sous vide chicken breasts. Thumbs up, these work nice and lucky for me have a short gentle learning curve."

Karl V. (4/5)

Fantastic!

"I hesitated ordering when the RFX first came out. I already have the Signals, so the RFX seemed like a luxury purchase. I should have bought the RFX sooner! Very easy to set up, especially if you already have the app installed. Seemless operation. I tried them first on some boneless chicken thighs. I had to weave the probes in, but they worked great!. Can’t wait to do some tri tip and brisket."

Jeffrey P. (5/5)

It just works.

"Had no issues connecting to WiFi or to the wireless transmitter. The strength on the probes remained strong for the duration of the cook. Cloud sync updates were timely and never lagged behind. Overall a great product."

Sean J. (5/5)

so far so good!

"this tool is incredibly convenient. my first cook with it was spot on! instructions were clear, and the quality of the components are obviously good. if i had one complaint, it would be that the grill temp probe was missing the grill clip, that I have received with past probes of this type. but again great job with this RFX series. I will stick with this one!"

ALEXANDER M. (5/5)

Workhorse

"Great Probes, But Plan Ahead Before Buying The ThermoWorks RFX probes themselves work great, and I’ve been very happy with their performance. My only regret is that I wish I had done a little more planning before purchasing. I originally bought the 2-probe kit thinking I could easily expand the system later as needed. Unfortunately, additional probes are around $99 each, so expanding my setup is going to cost me almost $700. If I could do it over again, I would have purchased a larger kit from the beginning. The RFX system works great, but if you think you’ll eventually want more probes, definitely price out the full setup before buying. Adding probes individually gets expensive very quickly."

Q&A

Can the RFX probe be used in an oven. I'm assuming yes, but all the photos show it only be used for barbecuing.
Yes, RFX can be used in the oven! Just make sure the RFX MEAT probe is inserted to the minimum immersion line.
Are the probes Bluetooth yet. I’m at competition with no internet. I need them to operate just in my work space
Yes, RFX GATEWAY can now communicate with your phone via Wi-Fi or Bluetooth.
In the picture there is the RFX wireless probe and an air temp probe. Does the package contain both? And how do they work together?
Yes, the RFX Starter kit includes both. In the app, you will see both the RFX MEAT temperature and the temperature from the ambient probe through the RFX GATEWAY.
Can the App be used on a laptop computer?
When on your laptop, you'll log into ThermoWorks Cloud, which is the same information you find on the app.
Can proves go into dishwasher “JW” help me last nite with startup - excellent help
Yes, RFX™ Wireless probes are dishwasher safe. Just place them securely and you’re good to go.
