Multi-channel wired monitoring against wire-free freedom
Managing long brisket and pork shoulder cooks requires continuous thermal awareness. The ThermoWorks Signals and the MEATER Pro 2 Plus offer two distinct technological solutions:
- ThermoWorks Signals (4-Channel Command Center): A commercial-grade standalone base station featuring a large backlit display and four wired Pro-Series probe channels (three food probes and one high-temperature grate air probe). It connects to Wi-Fi and Bluetooth simultaneously, graphing pit and meat temperatures with laboratory-grade ±1.8°F precision.
- MEATER Pro 2 Plus (Completely Wire-Free Smart Probe): Eliminates probe cables entirely. A slender 5 mm stainless steel probe houses 5 internal core sensors to identify the true center of the meat, while the rear FlameGuard ceramic head withstands direct fire up to 1,000°F.
Technical comparison
| Feature | ThermoWorks Signals | MEATER Pro 2 Plus |
|---|---|---|
| Channels | 4 Simultaneous wired channels | 1 Cut per wireless probe |
| Probe Style | High-temp Pro-Series silicone cables | 100% Wire-free stainless steel |
| Ambient Heat Limit | 572°F (Air probe) | 1,000°F (FlameGuard safe) |
| Display | Large physical backlit LCD | Smartphone app only |
| Fan Control | Compatible with Billows fan | None |
| Rotisserie Compatible | No (Wires will twist and snap) | Yes (Full 360° rotation) |
| Water Resistance | IP66 Splash-proof | 100% Waterproof (Submersible) |
Which workflow fits your cooker?
- Charcoal & Offset Smokers (Signals): When managing a Weber Smokey Mountain or offset stick burner, monitoring the pit grate temperature is as vital as monitoring the meat. Signals tracks both simultaneously, and can plug into a Billows fan to automate pit airflow while you sleep.
- Rotisseries & Open Grills (MEATER Pro): When roasting prime rib or whole turkeys on a motorized rotisserie, or searing steaks on a kettle, wires are cumbersome or impossible. The MEATER Pro stays completely inside the cut with zero cables to snag on grill grates or door gaskets.
Use our smoker time calculator to project target internal temperatures and plan your rest times with precision.
Who each one is for
Choose the ThermoWorks Signals if you want to monitor multiple pieces of meat alongside your smoker chamber temperature on one physical screen, or plan to automate charcoal temperature using a Billows draft fan.
Choose the MEATER Pro 2 Plus if you want completely wire-free convenience, cook on motorized rotisseries, or sear steaks over 1,000°F open flames without damaging probe cables.
Common questions
- Can the ThermoWorks Signals control firebox airflow fans?
- Yes. The Signals unit connects directly to the ThermoWorks Billows BBQ temperature control fan, automatically modulating airflow into charcoal smokers to hold exact pit temperatures overnight.
- Why is a wire-free probe required for rotisseries?
- Wired probe cables wrap around the spit rod and snap as a rotisserie rotates. Because the MEATER Pro 2 Plus has no external cables, it rotates freely inside whole chickens and roasts.
- How many individual cuts can each system monitor at once?
- The ThermoWorks Signals monitors four physical probe channels simultaneously on its backlit display. The MEATER Pro 2 Plus package monitors one cut per probe.
- How do the smartphone apps compare?
- Both offer cloud graphing, customizable alarm thresholds, and exportable temperature logs over Wi-Fi and Bluetooth.
