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.
