This comparison gets asked a lot — and it’s a fair question, because both are popular Bluetooth meat thermometers at similar price points. But once you understand how differently they work, the right choice becomes obvious for most people. Both also feature in my broader best Bluetooth meat thermometer guide, where they’re tested alongside three other top picks.

Head-to-head specs

The real difference: wires vs no wires

The MEATER probe is entirely wireless. It goes inside the meat — fully submerged — and transmits temperature data via Bluetooth from inside the cooking chamber. There is no cable running from the meat to a receiver. You close the oven or grill lid and walk away.

The TempPro TempSync uses traditional wired probes: thin stainless steel probes attached to heat-resistant cables that run from the meat to a receiver unit outside the oven or grill. You need to route the cables through a gap in your oven door or grill lid. It works well — millions of people cook with wired probes — but it is less elegant and requires a bit more setup.

For most cooks, the difference matters more than it sounds. Wires require planning: where does the cable exit? Is the gap large enough? Will the cable get pinched? A wireless probe eliminates this entirely. You insert it, close everything up, and the signal goes through the lid.

When the TempPro TempSync wins

Four probes is a genuine advantage for certain cooks. If you’re running a large smoker with chicken, ribs, and a pork shoulder all going at once, the TP25 lets you monitor every protein simultaneously. The MEATER Plus can only do one.

The 650-foot Bluetooth range is also significantly better than MEATER’s stated 165 feet (which in practice is closer to 50–80 feet through walls). If your smoker is far from your house, or you’re regularly losing Bluetooth connection with MEATER, the TP25’s range is a meaningful advantage.

When the MEATER Plus wins

For the most common cooking scenario — a single roast, whole chicken, or thick steak — MEATER’s no-wire design is genuinely superior. There’s nothing to route, nothing to kink, nothing to get pinched in the oven door. The ambient temperature sensor is built into the probe itself, not a clip-on attachment. The guided cook feature in the MEATER app (which calculates rest time and estimated finish time based on live temperature data) is best-in-class.

MEATER is also the better choice for charcoal grills and kamado-style cookers where routing a wire out of a sealed lid is awkward. The probe sits inside the cook chamber without any external cables.

How they compare in real cooking scenarios

Oven roasting (Sunday roast, whole chicken, lamb leg)

MEATER Plus is the better tool here. You insert the probe, put the joint in the oven, close the door, and monitor from your phone. No cable to route through the door seal, no risk of the cable getting pinched. The MEATER app’s guided cook calculates estimated finish time based on the live internal temperature — genuinely useful when you’re timing a roast around other dishes.

TempPro TempSync works fine in the oven but requires routing a cable through the door gap, which can let out heat over a long cook. For a single roast, this inconvenience is unnecessary when MEATER eliminates it entirely.

Charcoal grilling and kamado cookers

MEATER wins again. Kamado cookers (Big Green Egg, Kamado Joe) seal tightly — routing a cable out of the lid degrades the seal and can cause heat loss. MEATER’s probe sits inside the cooking chamber with no cable exiting. The same applies to kettle grills where you’re cooking indirect with the vents nearly closed: MEATER doesn’t interfere with airflow management.

The TempPro TempSync’s 650-foot range does give it an advantage once you have the cable sorted: you can monitor from across the garden without losing signal, which matters more on a long charcoal cook where you’re not constantly watching the grill.

Overnight low-and-slow smoking

This is where TempPro TempSync’s four probes earn their place. A pork shoulder and a brisket going simultaneously for 12 hours demands multi-protein monitoring — MEATER Plus can’t do that with a single probe. The TP25 also has a 40-hour battery life, meaning it outlasts any overnight cook without needing a recharge mid-session.

If you’re smoking one protein at a time, MEATER Plus handles it — but if your smoker regularly runs multiple racks or proteins simultaneously, TempPro TempSync’s four probes are the decisive advantage.

App comparison

The MEATER app (iOS and Android) is the standout in this comparison. The guided cook feature uses your target doneness, the current internal temperature, and the ambient cook temperature to calculate an estimated finish time — and updates it in real time as conditions change. The rest timer kicks in automatically when you pull the meat. For cooks who want hand-holding through the process, it’s genuinely excellent. The app interface is clean and well-designed.

The TempPro app is functional rather than guided. You set high and low temperature alarms for each probe, monitor the four readings simultaneously, and view a temperature history graph. There’s no guided cook mode or rest timer. For experienced cooks who just need the numbers, this is all you need. For less confident cooks, MEATER’s guided approach is more supportive.

Neither app requires a subscription. Both are free to use with the hardware. TempPro TempSync also has a physical display unit with a backlit screen showing all four probe temperatures — useful if you want to monitor without your phone, or if your phone battery is running low during a long cook. See my full meat thermometer buying guide for how this compares across the whole category.

The verdict

For most home cooks, the MEATER Plus is the better thermometer. The no-wire design removes friction from every cook, and monitoring a single protein covers 90% of everyday cooking. The TempPro TempSync is the right call if probe count genuinely matters to you — four simultaneous readings at this price is hard to beat. Neither is a wrong choice; they solve the same problem differently.

Frequently Asked Questions

Is MEATER better than TempPro TempSync?
It depends on your cooking style. MEATER Plus is better if you want a completely wireless probe with no cables and cook one protein at a time. TempPro TempSync is better if you need four simultaneous probes, longer Bluetooth range, or prefer a lower entry price. Both are accurate to +/-1C and produce reliable results.

Does the TempPro TempSync have an app?
Yes. The TempPro TempSync has a companion app (TempPro) that lets you monitor all four probes from your phone, set temperature alarms, and track cook history. The app works alongside the physical display unit, which shows all four probe temperatures simultaneously without needing your phone.

Can MEATER Plus monitor multiple probes?
The standard MEATER Plus is a single-probe system. To monitor two probes simultaneously, you need the MEATER Pro Duo. To monitor four probes, you need the MEATER Block (which holds and charges four probes and extends range via Wi-Fi).

What is the battery life of the TempPro TempSync?
The TempPro TempSync receiver is USB rechargeable and lasts approximately 40 hours per charge. The probes themselves don’t require separate batteries — they connect via cable to the receiver.

Which is easier to set up, MEATER Plus or TempPro TempSync?
MEATER Plus is simpler to set up: charge the bamboo block, pair with the app via Bluetooth, and it’s ready. TempPro TempSync requires connecting each probe cable to the receiver, pairing the receiver with the app, and routing cables appropriately for your cooking setup. Once set up, both work reliably. MEATER is meaningfully easier for first-time users.

Can I use MEATER Plus in a gas grill?
Yes. MEATER Plus works in gas grills, charcoal grills, kamado cookers, and kitchen ovens. The probe is rated for ambient temperatures up to 527F, which covers all standard grill environments. The wireless design is particularly well-suited to gas grills where you want to monitor temperature without a cable trailing from the grill lid.

Smoking demands more from a thermometer than any other cooking method. You’re monitoring internal temperature over 10–18 hours, often overnight, with the meat in a sealed chamber. Range, battery life, and probe count all matter in a way that doesn’t apply to a 25-minute oven roast.

These are the thermometers that actually hold up to a long smoke. Each also features in my best Bluetooth meat thermometer guide, where I compare them for everyday cooking as well as long smokes.

How I tested

Each thermometer was tested across multiple smoke sessions: brisket (12-15 hours at 225°F), pork shoulder (10 hours), whole chicken (3.5 hours), and spare ribs. I monitored Bluetooth range from inside the house during each cook, checked app stability over extended sessions, and tested battery life over consecutive cook days. Probe accuracy was verified against ice water before and after extended high-temperature use.

No products were provided free of charge by manufacturers. All were purchased at standard retail prices or tested via long-term personal use. See my full meat thermometer buying guide for how this compares across the whole category.

Frequently Asked Questions

What probe thermometer is best for a smoker?
The TempPro TempSync is the best all-round probe thermometer for smoking: four probes, 650-foot Bluetooth range, rechargeable, and priced around $45.99. For overnight cooks where you want to monitor from anywhere, the MEATER Pro Duo adds Wi-Fi connectivity. The Inkbird IBT-4XS is the best budget option with four probes around $49.99.

How many probes do I need for smoking?
Two probes cover most smoking scenarios: one in the meat, one monitoring ambient temperature near the grill grate. Four probes become useful when running multiple proteins simultaneously. If you only ever smoke one protein at a time, a single-probe thermometer like the MEATER Plus (with its built-in ambient sensor) is sufficient.

Can you leave a meat thermometer in the smoker for the whole cook?
Yes — that’s exactly what probe thermometers are designed for. All the thermometers in this guide are rated for sustained use in smoker environments. Wired probes should have cables routed away from direct flame. MEATER probes sit inside the meat throughout the entire cook without any external cable concern.

What temperature do you smoke a brisket to?
195-205F (91-96C) internal temperature. Many pitmasters target 203F specifically. At this temperature, collagen has fully converted to gelatin, giving you the tender, pull-apart texture that defines a properly cooked brisket.

Does smoke affect thermometer accuracy?
No. Smoke itself doesn’t interfere with probe temperature readings — the probe measures internal meat temperature directly via a metal sensor, not through the smoke-filled air. What smoke does affect is Bluetooth signal slightly, which is why range matters more for smoking than for a quick indoor cook.

What’s the difference between smoking and grilling in terms of thermometer needs?
Smoking runs much longer (10-18 hours vs 10-30 minutes for grilling) and often overnight, so battery life, Bluetooth/Wi-Fi range, and the ability to leave the probe in for the entire cook matter far more than they do for a quick grilled steak.
