ThermoWorks RFX vs MEATER Pro: a radio relay against a phone bridge

ThermoWorks RFX and the Meater 2 Plus solve the same overnight-brisket problem in genuinely different ways. RFX routes through a dedicated hardware relay, the RFX GATEWAY, sitting outside near the cooker. The Meater 2 Plus sends Bluetooth from the probe to its charger, which relays to your phone, and calls in a second device only if you want to go further than that (E·24). Whether either one actually holds a signal through fourteen hours of an unattended cook, a probe stuck in the meat, through a steel cooker wall, across a yard, through the side of a house, into a phone in someone's pocket, has almost nothing to do with the range number printed on either box. It has everything to do with what's actually carrying that signal, and what happens the moment something gets in the way. A claimed range in feet tells you almost nothing about which approach works in your yard, because every range claim on both boxes assumes conditions neither box states plainly enough to trust on its own.

We read ThermoWorks' current RFX product and help-center pages, an early pre-launch marketing claim to see how the range number has moved since, AmazingRibs' instrumented reviews of both probes, and forum and outlet accounts of how each system behaves in an actual house. The Meater side carries a naming complication we already dug into: our comparison of the Meater 2 Plus against the Combustion Predictive Thermometer found that Meater's own store now sells this hardware as MEATER Pro, with the manufacturer's current page and AmazingRibs' still-live review disagreeing on several numbers. We carry that same labeling discipline forward here: every Meater figure below is tagged by the page or review it came from, never blended into one number. These are two different manufacturers, so nothing in this comparison is one company's evidence counted twice.

The Meater 2 Plus, still going by two names

A housekeeping matter first, because it changes which Meater numbers below you can trust unlabeled. The meater-2-plus product URL at Meater's own US store no longer serves a page called Meater 2 Plus; it serves one titled for the renamed MEATER Pro line instead (E·2). That matches what we found putting together the Combustion comparison, not a new discovery, but worth re-confirming rather than assuming it still holds. The MEATER Pro review judges the probe on its own evidence.

The numbers still don't fully agree between pages. Meater's current MEATER Pro manufacturer page lists a 221°F internal probe limit, a 1000°F ambient/handle limit, a 2,500-foot open-air Bluetooth claim with 250 feet as the realistic home figure, and a $99.99 price (E·3). AmazingRibs' own review, still live and last updated July 10, 2026, tests and prices the identical hardware under the Meater 2 Plus name, and its spec box lists a 932°F handle rating, a 250-foot range described as an ideal-conditions figure rather than a typical one, and an $80.00 price (E·4). We found no change log reconciling the handle-temperature gap, so every Meater spec in this comparison is labeled by which page it came from, the same rule our earlier comparison used.

The short table

Sensors: a wired grill clip against a sensor in the handle

Both probes throw more than one sensor at the placement problem, but they solve the ambient-reading problem in opposite ways. Meater builds 5 sensors along the food end of its probe and a sixth into the handle, reading the air near whatever the handle happens to be sitting in (E·3). RFX puts four sensors near the tip and none in the handle at all; for the reading that isn't touching the food, it swaps in a separate wired probe with a grill clip that lives away from the meat entirely, plugged into the Gateway rather than riding the food probe (E·5, E·7).

That is a real, checkable design difference, not a marketing distinction. A sensor riding in a probe's handle sits wherever the handle sits, usually a few inches from the food it's supposed to be helping you avoid overcooking, and a third-party compilation of Meater's own guidance notes as much: the ambient reading changes over time even while the cooker's actual temperature stays flat (E·8). A clip mounted on the grate is deliberately somewhere else, doing one job. Neither maker has published an independent instrumented test of its own ambient probe's tolerance against a reference bath, so this section describes architecture, not accuracy. We can tell you which design makes more physical sense. We can't yet tell you which one reads truer.

Accuracy: not really a contest

On the one instrumented test each probe has, the food-temperature question is close to settled, and settling it does not really favor either probe. AmazingRibs read the RFX MEAT probe at 134.9, 160.2 and 204.9°F against 135, 160 and 205°F targets, a worst-case miss of 0.2°F, and called the results near-perfect (E·9). The same reviewer's Meater 2 Plus test came back at 134.7, 159.9 and 205°F against those same three targets, a worst-case miss of 0.3°F (E·4). RFX measured a shade tighter on its one test, but on a single unit checked against an unnamed reference at only three points, a tenth of a degree of daylight is well inside the noise of the protocol itself, not a demonstrated accuracy edge. Both sit comfortably inside their own claimed tolerance, ±0.9°F for RFX and ±0.5°F for Meater (E·6, E·3). If you're choosing between these two on food-probe accuracy alone, the evidence in this packet won't give you a reason.

Declared vs measured

Connectivity architecture: a radio relay against a phone bridge

Headline range numbers are close to meaningless without the wiring behind them, and these two products are wired completely differently. RFX MEAT talks to the RFX GATEWAY over a patent-pending Sub-1 GHz radio frequency, a frequency ThermoWorks chose specifically because it pushes through steel smokers and cast-iron Dutch ovens better than Bluetooth does (E·1). The Gateway then does the rest of the work on its own: it joins a 2.4GHz WiFi network and relays your probe's data to the cloud and the app without your phone anywhere nearby (E·11). Bluetooth still shows up in this system, just in a narrower role. It's how the Gateway first receives its WiFi password during setup, and, as of an app update in mid-2025, it's also available as an offline local mode when WiFi isn't an option (E·11, E·21).

Meater has no WiFi relay, but it does have a relay stage. The probe talks Bluetooth to its charger, which is in the box, and the charger talks Bluetooth to your phone; Meater's support guide gives up to 33 feet for the first leg and up to 250 for the second and says to keep the charger as close to the cooker as possible (E·24). That is a smaller job than the RFX Gateway's, but it is still a piece of hardware you place. Go further than Bluetooth's own range and there's no separate box to buy beyond that charger: you press a second phone or tablet into service running MEATER Link or MEATER Cloud, and that device becomes the bridge (E·12). It's a genuinely different kind of system, not just a smaller number on a spec sheet. RFX asks you to own, place, and keep charged one more piece of hardware. Meater asks you to park its charger near the cooker and to have a spare device around on the rare cook where Bluetooth alone won't reach.

The range numbers, and why the feet don't settle anything

Here's where the marketing gets messy on both sides. ThermoWorks' current RFX Starter Kit page claims 1,500 feet line-of-sight, unobstructed, with roughly 560 feet once something gets in the way, according to an independent review that quotes the same manufacturer figures (E·6, E·16). ThermoWorks' own help center cautions that a line-of-sight number represents a best case with no physical barriers at all, and recommends judging wireless gear by radio frequency rather than by the distance claim printed on the box (E·13). Before RFX ever shipped, AmazingRibs' preview article quoted ThermoWorks touting an industry-leading 2,132 feet line-of-sight, a number that appears on no current ThermoWorks page we could find (E·14). Nobody we found has explained the gap. It could be a pre-launch spec that got revised once real units shipped, or a preview article that overstated an early claim. Either way, the sound move is to trust the number on the page selling the product today, 1,500 feet, and treat 2,132 as a claim that didn't survive contact with launch.

Meater's own range story splits the same way, and we already flagged it above: 2,500 feet open air on Meater's current page against a 250-foot figure AmazingRibs explicitly calls an ideal-conditions number in its still-live review (E·3, E·4). Two different manufacturers, two different products, the identical pattern: the bigger number comes from marketing copy, and the number attached to an actual test or a stated caveat is smaller.

Real-world reports for RFX split by house, which is itself the finding. One reviewer measured about 300 feet through a single wall before losing the connection to their Gateway (E·16). Another reported the probe staying connected after moving a roast from a smoker outside straight into an oven inside the house, through two exterior walls and an oven door (E·17). A Pitmaster Club forum poster called the hardware rock solid with zero drops from probe to Gateway or Gateway to WiFi (E·18). A year-long review reported no dropouts across more than a year of overnight cooks (E·19). And a reader comment on that same Smoked Meat Sunday review described regular disconnects during oven roasting even with the Gateway sitting one to two feet away (E·16). Five accounts, five different outcomes, none of them wrong. Range for this class of product depends on your specific walls, your specific unit, and your specific router placement more than any spec sheet, ours included, can promise.

Software you're trusting to keep working

Both of these are wireless products whose usefulness depends partly on an app neither company is obligated to keep updating forever, and partly, for RFX, on a cloud account. At retrieval, the ThermoWorks app's App Store listing showed version 1.102.4, last updated July 30, 2025, with a release history that includes adding an offline Bluetooth Only mode back in June 2025, something Engadget's launch-era review had specifically noted RFX lacked (E·15, E·21). The MEATER app's listing showed version 5.0.0, updated August 6, described in its own release notes as a major redesign (E·22).

RFX carries one more software dependency Meater doesn't: a ThermoWorks Cloud account for the Gateway to sync through. ThermoWorks' help center names three of its other BBQ devices, BlueDOT, Signals and Smoke Gateway, as needing no billing plan at all, with free access, notifications and storage (E·20). RFX isn't on that list. We could not find ThermoWorks' specific device-limit pricing for RFX beyond that omission, so we can't tell you what, if anything, a multi-probe household actually pays past a free allotment, only that the free pass other ThermoWorks BBQ devices get doesn't appear to extend to RFX (E·20). Neither app currently offers a genuine predicted-finish-time feature we could confirm; at retrieval ThermoWorks' had none, and this comparison did not independently test Meater's own time estimate against a clock (E·10, E·3).

Price, this month

At retrieval, ThermoWorks priced the RFX MEAT probe at $99.00 and the Gateway at $89.00 bought separately, a combined $188.00 that matches the compare-at price on its own 1-probe starter kit, itself selling for $179.00 (E·1, E·5, E·6). A still-live AmazingRibs review lists that same 1-probe kit at $159.00, a lower number than ThermoWorks' current page shows (E·9). Both figures sit above launch-era pricing from late 2024, when Engadget listed the probe at $89 and the Gateway at $79 individually (E·15). Meater 2 Plus, meanwhile, sat at $80.00 at AmazingRibs against a $99.99 manufacturer list price for the same hardware under the MEATER Pro name (E·4, E·3). Line the current numbers up and Meater is the cheaper way into this category by a wide margin, one probe against two pieces of hardware, even before RFX's cloud account enters the picture.

What would change this

An independent range test that put both systems through the same house, the same walls, on the same day, would replace today's pile of mismatched anecdotes, one reviewer's 300 feet, another's clean signal through an oven door, a reader's dropouts at two feet, with an actual number worth comparing. ThermoWorks explaining the gap between its pre-launch 2,132-foot claim and its current 1,500-foot spec, even a sentence, would resolve a question this comparison can't. An independent instrumented test of RFX's wired ambient probe, checked against a reference bath the way each maker's food probe already has been, would close a testing gap that currently applies to both products' ambient readings. And a clear statement of what a multi-probe RFX household actually pays once free ThermoWorks Cloud limits run out would let a reader do real total-cost-of-ownership math instead of guessing from an absence. For where both sit among the main leave-in probes, see our wireless meat thermometer guide.

For the reader whose actual question is simpler than any of this, whether the chicken hit a safe internal temperature, our guide to claimed versus independently measured accuracy covers instant-read pens that answer it for a fraction of either system's price, no probe left in the oven required.

Correction, 28 October 2026: an earlier version said the Meater 2 Plus talks Bluetooth directly to your phone. Meater's own support guide describes the path as probe to charger, then charger to phone, with the charger kept close to the cooker, and the connectivity sections now say so (E·24).
