Choosing among BBQ thermometers & controllers often comes down to one practical tension: do you want the ThermoHaven G4's app-led remote control, or the ThermoMaven G2's explicitly two-probe wireless setup? The useful answer is not that one wireless meat thermometer suits every cook. It is which monitoring style matches the way you grill, smoke, roast, or manage a BBQ.
Quick verdict
Choose the ThermoHaven G4 when Smart App Control is the deciding feature for a grill, BBQ, or smoker. Choose the ThermoMaven G2 when a two-probe setup with WiFi and Bluetooth is more important. Both are digital meat thermometers with instant-read, leave-in, oven-safe, easy-clean, and remote-read features, so the choice comes down to connectivity, probe setup, price, and condition.

Where each product wins
ThermoHaven G4 wins the app-first brief. Smart App Control is part of its product title, and the description presents remote control through a smart app. That makes it the more direct match for someone who wants to monitor meat while stepping away from the grill, BBQ, or smoker.
ThermoMaven G2 wins the multi-probe brief. Its title and description call out two probes, WiFi, and Bluetooth, while the wireless range is stated as up to 3000 ft. The mobile app also includes alerts and presets, giving the G2 a clearly defined monitoring setup for BBQ, smoking, grilling, roasting, ovens, and rotisseries.
Product notes
ThermoHaven G4 Wireless Meat Thermometer

The ThermoHaven G4 is a sensible choice when remote app control is the main reason to add a wireless meat thermometer. Its title specifically covers grill, BBQ, and smoker use, while the feature list includes leave-in use, oven-safe operation, instant read, easy cleaning, and remote read. Those details give it a broad cooking-tool profile without requiring a separate use case for every cooking session. The concrete limitation is the price: at USD 109.99, it is $60 higher than the ThermoMaven G2. Choose the G4 when the Smart App Control phrase reflects a feature you expect to use regularly; otherwise, the higher listed price is harder to justify from the shared cooking functions alone.
ThermoMaven G2 Wireless Meat Thermometer

The ThermoMaven G2 brings a more explicitly defined wireless setup: a smart base station, dual waterproof probes, WiFi and Bluetooth connectivity, plus a mobile app with alerts and presets. Its rechargeable design is another practical detail for cooks who plan to keep a meat temperature monitor in regular rotation. The main limitation is its open-box condition, which may rule it out for shoppers who specifically want new-condition gear. The G2 is the stronger match for someone who wants the product's two-probe configuration and named wireless connections, rather than prioritizing the G4's Smart App Control wording. Its listed cooking range also includes BBQ, smokers, grills, ovens, and rotisseries.
Final choice by use case
- App-led remote monitoring: Choose the ThermoHaven G4, whose title puts Smart App Control at the center and whose features include remote read.
- Two-probe monitoring: Choose the ThermoMaven G2 for the explicitly named dual-probe setup.
- WiFi and Bluetooth: The ThermoMaven G2 is the direct fit because both connections are named.
- Grill, BBQ, and smoker focus: The ThermoHaven G4 matches those three cooking contexts directly in its title.
- Broader named cooking coverage: The ThermoMaven G2 is described for BBQ, smoking, grilling, roasting, ovens, and rotisseries.
The final decision is straightforward: pick the G4 when app control is the priority, and pick the G2 when two probes and explicitly named WiFi and Bluetooth matter more.
