As Seen On
“Connectivity was excellent, both around the house over Wi-Fi and over cellular to the cloud. I walked about 430 feet away from the backyard to the end of the cul-de-sac, holding the base station, and it was still connected to the probe sitting in a sponge, within a cast-iron Dutch oven, resting in a steel smoker.”

Automatically stores cooking data in the cloud
How RFX stacks up
Move freely around your home, yard, or business.
When unobstructed and in direct line of sight, our signal reaches up to 1,500 ft between RFX MEAT and RFX GATEWAY. (That’s over 1,000 ft further than our closest Bluetooth competitor.)
The secret behind our superior signal
Bluetooth operates at a 2.4 GHz frequency, which means more signal peaks per second. Higher frequency signals experience greater attenuation, or loss of strength, when encountering obstacles like smoker walls. That's because shorter wavelengths are more easily absorbed.
The patent-pending sub-GHz wireless technology of RFX operates at a much lower frequency, 433 MHz, which translates to fewer signal peaks per second (longer wavelengths) and significantly better penetration through barriers. This lower frequency allows RFX to blast through thick metal smokers, home walls, and other robust obstacles, ensuring a strong, reliable connection no matter where you are. Stay truly connected with RFX.
Nothing Works like ThermoWorks
Accuracy in every sensor
Roast, smoke, grill, and fry meats to restaurant-level perfection. Four hidden probe sensors are independently calibrated to find the true thermal center of your cook—and deliver ±0.9°F accuracy between 14 and 212ºF.
Precision you can trace
Each RFX MEAT probe comes with a digital certificate of calibration to certify that your instrument has been tested against international laboratory standards, including those set by the National Institute of Standards and Technology (NIST).
Ambient temperatures you can trust
Competitors’ built-in ambient sensors give inaccurate readings as cold meat acts as a heat sink, pulling heat from the metal probe and skewing the measurement of the ambient sensor by 75°F or more. Even if these sensors were accurate, they're placed in an evaporative cooling zone around the meat. This means your ambient sensor is not reading the accurate temperature of your cooker. Our Pro-Series® Air Probe plugs directly into RFX GATEWAY for precise placement and true ambient temperature measurements.
Multi-device management for businesses
RFX GATEWAY handles 50+ wireless RFX MEAT probes simultaneously, ideal for professional kitchens and large-scale operations. We’ve future-proofed RFX: Your gateway is also compatible with a whole suite of forthcoming ThermoWorks RFX products.
What the pros are saying
“I’ve been waiting two years for this. RFX will not only supplant the existing products but create a new category of reliability that doesn’t really exist.”
—Jeremy Yoder, culinary mastermind behind the “Mad Scientist BBQ” YouTube channel
“Now that’s technology you can count on.”
—Tuffy Stone, legendary pitmaster, restaurateur, and BBQ Hall of Famer

How RFX works
Communication flexibility for every cooking scenario.
1. RFX MEAT connects to RFX GATEWAY via patent-pending sub-GHz RFX wireless technology.
2. When connected to Wi-Fi, RFX GATEWAY sends data to our mobile app via ThermoWorks Cloud. Or, cook offline with a direct gateway-to-smartphone Bluetooth connection.
Go further with ThermoWorks App + Cloud
Supervise in real-time:
Track your cook from anywhere, set crucial alerts, and instantly view cloud data in our mobile app.
Access powerful data tools:
Monitor temperature highs and lows, visualize data with graphs, and make informed adjustments using the cloud.
Connect devices securely:
Lock any device to your cloud account to protect data and prevent accidentally connecting to your neighbor’s gateway.
Scale up seamlessly:
Upgrade features with a paid Cloud Pro account — required for 11+ devices. (RFX probes and gateways count as individual devices).

Important Information
Essential Steps to Maximize Performance and Extend the Life of Your RFX MEAT™
FULL IMMERSION:
Always ensure that the probe is fully inserted up to the immersion line.
This will protect the internal electronic components and prevent excessive heat exposure that will damage your RFX MEAT probe and void your warranty.
NOTE: Your food may change shape as you cook. If you notice that your food is contracting away from the immersion line, push your probe in until the immersion line is reached.
CLEANING:
Clean your probe thoroughly after every use. For proper charging, RFX MEAT probes should look “shiny” and clean after each use. Food particles, smoke residue, and polymerized oil can accumulate on the probe, discoloring them and forming a varnish that prevents proper charging, shortening battery life.
TIP: Use a mildly abrasive cleaning pad for regular cleaning. If the varnish is heavy and the probe resembles your grill grates, use Bar Keeper’s Friend with your abrasive pad to restore it.
