I\u2019ve been using the ThermoWorks RFX<\/a><\/strong> for more than a year now, and I can honestly say it\u2019s one of the most dependable wireless thermometer systems I\u2019ve ever used.<\/p>\n

A lot of wireless probes sound good until you actually put them in a smoker, close the lid, walk away, and expect them to keep working. That\u2019s usually where the trouble starts. In my experience, the RFX has been different. It has stayed connected well, given me readings I trust, and made it easier to cook without babysitting the smoker every few minutes.<\/p>\n

ThermoWorks designed the RFX system around a wireless probe called the RFX MEAT and a separate RFX GATEWAY. Instead of relying on standard Bluetooth from the probe itself, the probe sends its data to the gateway using ThermoWorks\u2019 patent-pending 433 MHz radio frequency system with a claimed range of up to 1,500 feet line of sight. From there, the gateway sends your cook data to the ThermoWorks app over Wi-Fi or Bluetooth, which is a big part of why this system feels more solid than a lot of other wireless options.<\/p>\n

One of the biggest selling points for me is that this probe does not just read one internal spot. The RFX probe has four independently calibrated internal sensors built into it, and ThermoWorks says the system automatically identifies the true thermal center for more precise doneness tracking. That matters because meat does not always cook evenly from one end to the other, especially on larger cuts like brisket, pork butt, or turkey breast.<\/p>\n

Another thing I like is that it is built to handle real barbecue conditions. ThermoWorks lists the external operating range at 0 to 1000\u00b0F (-18 to 538\u00b0C) and the internal operating range at 0 to 212\u00b0F (-18 to 100\u00b0C). Accuracy is listed at \u00b10.9\u00b0F from 14 to 212\u00b0F. The probe is also rated IP69K waterproof, which gives a little peace of mind when it comes to cleanup and day-to-day use.<\/p>\n

Battery life is another strong point. ThermoWorks says the probe will run up to 52 hours on a 10-minute quick charge and 65+ hours on a full 20-minute charge. The gateway itself takes about four hours to charge and runs for about 24 hours on a full charge.<\/p>\n

In actual use, what I\u2019ve appreciated most is confidence. If I\u2019m cooking a pork butt overnight or running a long brisket cook, I want to know what\u2019s going on without opening the cooker all the time or wondering whether the signal dropped out. That\u2019s where the RFX has shined for me. It has made long cooks easier and less stressful, which is exactly what a wireless system ought to do.<\/p>\n

Main Features<\/h2>\n

Four Internal Sensors<\/h3>\n

This is one of the biggest features of the RFX. Instead of relying on one reading point, the probe uses four internal thermistor sensors and can identify the lowest reading as it tracks the thermal center. ThermoWorks also offers an Advanced Mode in the app that lets you view the individual sensor channels in addition to the calculated lowest reading.<\/p>\n

Long-Range Wireless Connection<\/h3>\n

ThermoWorks states that the probe communicates with the gateway using patent-pending sub-1 GHz radio frequency with a range up to 1,500 feet line of sight. That is one of the main reasons this system stands apart from many Bluetooth-only probes.<\/p>\n

App-Based Monitoring<\/h3>\n

The gateway pushes data to the ThermoWorks app and cloud over Wi-Fi or Bluetooth so you can monitor your cook, set alerts, and review your cook history.<\/p>\n

Built for High-Heat Cooks<\/h3>\n

The probe is designed for low-and-slow smoking as well as hotter grilling cooks, with ThermoWorks listing an external heat rating up to 1000\u00b0F (538\u00b0C).<\/p>\n

Fast Charging and Long Battery Life<\/h3>\n

ThermoWorks lists 0\u201380 percent charge in 10 minutes, 0\u2013100 percent in 20 minutes, and up to 52 hours of runtime on a quick charge.<\/p>\n
