Get your RFX Wireless System up and running in under two minutes! This comprehensive video guide walks you through everything you need to know straight out of the box. Watch to see exactly what is included in your starter kit, followed by a step-by-step visual tutorial on downloading the ThermoWorks app, connecting your RFX GATEWAY to your Wi-Fi, and pairing your RFX MEAT probe. You will also get a quick look at how to adjust your temperature transmission intervals for different types of cooks.

Download the ThermoWorks App from the App Store or the Google Play Store. If you already have it, make sure you’ve updated to the latest version.
Once you download the app, follow the on-screen prompts to create an account.

You will need to set up RFX GATEWAY™ before setting up RFX MEAT. Plug in your RFX GATEWAY, check that your phone’s Bluetooth is turned on, and you’re ready to start!

Open the app, click the [+Device] button in the bottom right corner, and follow the in-app instructions to add RFX GATEWAY.

RFX GATEWAY LED Status:

  • Blue: First time setup mode
  • Flashing Green: Connected to Wi-Fi
  • Solid Green: Connected to ThermoWorks Cloud.
  • Flashing Red: Cloud connection issue
  • Solid Red: Wi-Fi connection issue
  • Flashing Green/Blue: Firmware update in progress.

*RFX Gateway requires a 2.4 GHz Wi-Fi connection.

After you’ve set up RFX GATEWAY, navigate back to the Devices page. Click the [+Device] button again, click RFX MEAT, and then follow the in-app instructions.

Now is the time to customize your RFX MEAT settings. You can change your device name, ring colors, high and low alerts, and more. A lot of power in the palm of your hand. 

Once you’re ready, insert RFX MEAT to the immersion line and get cooking!

Discover the engineering behind the RFX MEAT probe. Explore its advanced multi-sensor design and learn proper placement techniques to guarantee unmatched accuracy, safety, and durability on every cook.

Your food is only as done as its least-cooked part. That’s why the RFX MEAT probe features four individually calibrated sensors packed into the tip. The ThermoWorks app automatically reports the lowest reading, guaranteeing you always find the true thermal center of your meat. For the temperature-obsessed, you can enable Advanced Mode to view all four sensor readings in real time and see exactly what's happening inside your cook.

To protect the probe's advanced internal electronics, it must be inserted into your food at least up to the Minimum Immersion Line. The meat acts as a natural insulator, keeping the sensitive internal components within their safe operating range (up to 212°F/100°C), while allowing the exposed handle to withstand extreme ambient temperatures up to 1,000°F (538°C). Failing to insert the probe to this line can result in permanent damage to the device.

For the most accurate readings and ultimate protection, insert the probe up to the Recommended Immersion Line. While the minimum line keeps the electronics safe, pushing the probe to the recommended depth ensures that intense ambient heat from your smoker or grill doesn't travel down the metal shaft and falsely elevate your internal temperature readings. Proper immersion guarantees real data, not guesswork.
