MEATER Plus vs ThermoWorks Signals: Which Smart Meat Thermometer Wins?
If you have ever pulled a brisket off the smoker only to discover it is dry and overcooked, you already know why a smart meat thermometer matters. Two names dominate the conversation among serious grillers and smart-home cooks: the MEATER Plus and the ThermoWorks Signals. Both promise set-and-forget cooking with phone alerts, but they approach the job from completely different philosophies. One is a sleek, single-probe wireless wand designed for elegance and guided cooking. The other is a rugged, four-probe command center built for long smokes and data nerds.
In this head-to-head comparison, we break down design, accuracy, connectivity, app experience, and overall value so you can choose the right tool for your cooking style.

Design & Build Quality
The MEATER Plus is essentially a polished stainless-steel rod with a pointed tip and a ceramic handle. It is minimalist to the point of being almost invisible once it is inserted into a roast. The bamboo charging block doubles as a display stand and looks at home on a kitchen counter or mounted near a grill. There are no wires, no base station on the grill itself, and nothing to snag on a lid. For anyone who values clean lines and a small footprint, the MEATER Plus is the clear aesthetic winner.
The ThermoWorks Signals, by contrast, looks like something you would find in a commercial test kitchen. The base unit is chunky, rubberized, and built to survive being knocked off a prep table. It has a large backlit LCD, physical buttons you can press with gloved hands, and a magnetic back plus a built-in stand. Four color-coded probe ports line the side, and each probe uses a braided, heat-resistant cable. This is not a pretty device — it is a workhorse. If you are the kind of cook who drops things, splashes sauce everywhere, and leaves gear outside in the rain, Signals will outlast the MEATER Plus by years.

Probe Performance & Accuracy
Both devices claim ±1.8°F accuracy, and in real-world testing they trade blows. The real difference is in how they measure.
The MEATER Plus uses a single probe with two sensors — one at the tip for internal meat temperature and one in the ceramic handle for ambient grill temperature. This dual reading is brilliant for low-and-slow barbecue because you can see exactly what the meat is doing and what the pit is doing on the same screen. The downside is that the internal sensor maxes out at 212°F, which means you cannot use the MEATER Plus to track the surface temperature of a screaming-hot steak or a pizza stone. It is optimized for roasts, poultry, and briskets, not searing.
The ThermoWorks Signals uses separate, dedicated probes for each food item plus a dedicated ambient probe with a grill clip. The Pro-Series probes are the same lineage used in ThermoWorks' legendary Thermapen, and they respond noticeably faster when you open a smoker lid or move a probe between cuts. Because each probe is independent, you can monitor a whole turkey, a rack of ribs, a side of vegetables, and the pit temperature simultaneously — something the single-probe MEATER simply cannot do. The ambient probe also handles much higher temperatures, making Signals the better choice for pizza ovens, high-heat searing, and kiln-style smokers.
If you cook one large cut at a time and want guided doneness predictions, MEATER Plus feels more refined. If you juggle multiple proteins or run a competition-style cook, Signals is the only realistic option.
Connectivity & Range
This is where the two products diverge most dramatically, and it is usually the deciding factor for buyers.
The MEATER Plus connects directly to your phone over Bluetooth, with an effective range of about 165 feet in open air. For true remote monitoring — say, watching a brisket from your living room while the grill is in the backyard — your phone must stay within Bluetooth range to act as a bridge to MEATER Cloud. Alternatively, you can add the MEATER Link hub or a second device running the MEATER Link app to serve as a dedicated bridge. It works, but it adds complexity and another gadget to manage.
The ThermoWorks Signals has Wi-Fi built directly into the base unit. You connect it to your home network once, and from that point on the device reports to ThermoWorks Cloud independently of your phone. You can leave the house, drive across town, and still check your cook from a browser or the app. This is a huge advantage for overnight smokes, long road trips with a trailer-mounted smoker, or anyone who does not want to babysit a Bluetooth bridge. The trade-off is that Signals depends on your home Wi-Fi reaching the grill — if your router does not cover the patio, you will need a Wi-Fi extender or mesh node.
For users building a connected outdoor space, pairing Signals with a reliable mesh system is worth the investment. Our guide to the best mesh Wi-Fi systems covers options that handle backyard coverage well.
App Experience & Smart Home Ecosystem
The MEATER app is polished, modern, and heavily opinionated in a good way. You select your protein, target doneness, and cooking method, and the app calculates estimated finish time using its predictive algorithm. It walks you through resting, carryover cooking, and even suggests when to pull the meat off early. The interface is gorgeous, the animations are smooth, and it integrates with Alexa, Google Assistant, and Apple Watch. For a home cook who wants a digital sous-chef, MEATER is unmatched.
The ThermoWorks Signals app is more utilitarian. It gives you live graphs, high and low alarms for every probe, and a simple web dashboard you can open on any browser without installing anything. There is less hand-holding and more raw data. You set your own targets, you interpret your own curves, and you make your own calls. Power users love this; beginners sometimes find it intimidating. Signals does not currently integrate with voice assistants in a meaningful way, and there is no guided cook mode — it trusts you to know what you are doing.
Neither ecosystem requires a subscription, which is a refreshing change from much of the smart-home world. Both store cook history in the cloud so you can review past sessions, which is invaluable when you are dialing in a new recipe or trying to reproduce a championship brisket.
Value & Long-Term Ownership
The MEATER Plus typically retails in the mid-range tier and includes everything you need in the box: probe, bamboo charger, and USB cable. Replacement probes are moderately priced, and the rechargeable battery should last for years before it shows meaningful degradation. The main long-term cost is the optional MEATER Block or Link hub if you want multi-probe functionality or hands-free cloud bridging.
The ThermoWorks Signals sits in the premium tier, often costing nearly twice as much as the MEATER Plus. However, you get four probes in the box, and the base unit supports up to six. Replacement Pro-Series probes are reasonably priced and widely available. The AA battery approach sounds old-fashioned, but it is actually a strength — when batteries die at hour 14 of a smoke, you swap in fresh ones in ten seconds rather than waiting for a recharge. ThermoWorks also has a reputation for excellent customer support and long product lifespans, which matters when you are spending this kind of money.
On pure cost-per-probe, Signals wins. On cost-per-feature-for-a-casual-cook, MEATER Plus is the better deal.
The Verdict: Who Should Buy What?
There is no single winner here — only the right tool for the right cook.
Choose the MEATER Plus if:
- You mostly cook one large protein at a time — roasts, whole chickens, prime rib, or brisket.
- You want a guided, app-driven experience with predictive finish times.
- You value sleek design and a wire-free setup.
- You cook primarily on a grill or oven that is within Bluetooth range of your phone.
- You want Alexa or Apple Watch integration for hands-free checks.
Choose the ThermoWorks Signals if:
- You regularly cook multiple items at once — competition barbecue, holiday feasts, or batch meal prep.
- You need true Wi-Fi connectivity without a phone bridge, especially for overnight smokes.
- You work in high-heat environments like pizza ovens or sear stations.
- You want rugged, commercial-grade build quality that can survive real abuse.
- You prefer raw data and manual control over guided cooking modes.
Many serious enthusiasts eventually own both — the MEATER Plus for elegant weeknight roasts and the Signals for weekend-long barbecue sessions. If you can only pick one, let your typical cook decide: elegance and guidance point to MEATER, while capacity and independence point to Signals.
Frequently Asked Questions
Can I use the MEATER Plus and ThermoWorks Signals together?
Yes. Because they use separate apps and do not interfere with each other's wireless signals, many pitmasters run a MEATER Plus in the main roast while using Signals to monitor side dishes, ambient pit temperature at multiple points, or a second protein. Just be aware that you will need to check two different apps during the cook.
Do either of these thermometers require a paid subscription?
No. Both MEATER Cloud and ThermoWorks Cloud offer remote monitoring, cook history, and firmware updates at no additional cost. Neither company currently locks core features behind a paywall, which is one of the reasons both devices remain popular compared to subscription-heavy competitors.
Which thermometer is better for smoking brisket overnight?
For unattended overnight smokes, the ThermoWorks Signals has the edge because its built-in Wi-Fi does not depend on a phone staying within Bluetooth range. You can sleep inside, leave the house for supplies, or check in from a hotel room while traveling. The MEATER Plus can do overnight cooks, but only if you keep a bridge device (phone or MEATER Link) powered and within range of the grill the entire time.
Are replacement probes easy to find for both brands?
Yes. Both MEATER and ThermoWorks sell replacement probes directly through their websites and through major kitchen retailers. ThermoWorks Pro-Series probes are particularly well-stocked because they are shared across several ThermoWorks products. MEATER replacement probes are model-specific, so make sure you order the correct generation for your charger.
