The Limitations of the Stock Thermometer
Most modern grills feature a stock or dome thermometer. A built-in thermometer is designed to be convenient, allowing users to check the temperature without lifting the lid or inserting probes into the meat. However, the very design that provides convenience and ease to the user also imposes limitations on its functionality, particularly in delivering accurate temperature readings.
Since accurate temperature control is crucial for producing the highest-quality grilled meat, it’s recommended that you upgrade your Big Green Egg with grilling accessories to enhance your grilling results.
Why is there a need to upgrade to a thermometer?
Built-in dome thermometers measure the air above the lid, not the cooking surface. Since heat naturally rises, the air temperature in the dome can vary significantly from the cooking surface.
Another factor that causes inaccurate temperature readings in a dome thermometer is the airflow bias. Since heated air circulates within the dome, it can create uneven “hot spots.” Some areas might be hotter than others. Therefore, it does not read the “average” temperature but rather the temperature of a specific spot.
The ProTemp S1 thermometer effectively replaces the original analogue gauge that comes with a Big Green Egg grill. Therefore, it can measure the temperature on the top, just as the original analogue gauge. However, its capabilities go beyond that because of its longer thermometer stem, which allows it to reach closer to the grate. The ability of the longer thermometer stem to contact the cooking surface provides much-improved accuracy.
Another feature that sets the ProTemp S1 apart from the original analogue gauge is its use of a platinum sensor. In contrast, the built-in thermometers use an NTC sensor.
Platinum sensors are fundamentally more accurate in their temperature readings. The material’s electrical resistance is linear with temperature, making it more predictable and precise. On the other hand, NTC sensors use semiconductor materials that can cause temperature to drop even as temperature rises.
Platinum is more chemically and physically stable, with an accuracy range of ±0.1°C or better. Even after years of use, these sensors remain accurate with highly repeatable results. It makes it ideal for high-precision applications, such as grilling meat or low-and-slow cooking.
Finally, upgrading to the ProTemp S1 for your Big Green Egg allows you to utilise temperature compensation. External temperature changes easily influence most sensors and thermometers. As a result, measurement errors can occur without temperature compensation. You have this capability with the ProTemp S1 via the app, which detects temperature variations and compensates for them accordingly for a more reliable reading.
The next time you fire up the grill and consider using the stock thermometers, think twice. Maximise your grilling performance with the right Kamado grill accessories, such as a Big Green Egg thermometer upgrade.
Why Precision Temperature Control Matters in Kamado Cooking
Temperature control is crucial in all types of cooking, but especially in Kamado cooking. Why so? It’s because Kamado grills, such as the Big Green Egg, are known for their efficiency and heat retention.
The ceramic material is effective at locking in heat and providing airflow within the dome, ensuring consistent, even heating. However, this cooking method is also sensitive to temperature changes. Any minor fluctuations in the grill’s temperature can result in undercooked or overcooked food if you’re not paying attention.
Even if you’re off by two degrees or cooked your steak for just a minute or two more, you cannot enjoy the same flavour or texture. You wouldn’t want that on a pricey piece of meat!
One thing that is particularly challenging with Kamado cooking is that it differs from a typical grill. It is made of thick, ceramic walls. Ceramic is specifically chosen for its insulating properties, working like a heavy-duty thermal blanket that cooks the meat while maintaining steady heat.
In particular, Kamado grills can retain heat for extended periods, providing greater stability during cooking. For example, it can maintain a temperature of 225°F for up to 12 hours without requiring you to constantly add more charcoal. The ceramic does most of the work, distributing the heat inside, and does not cool off easily.
However, the Kamado heat retention capability can be a double-edged sword. It means that the temperature remains consistent throughout, with little room for adjustments as you cook. If you’re not careful with grill heat management, you could easily burn your meat. There is no way to lower the temperature instantly. If you exceed the recommended temperature for your meat, you won’t be able to “cool” the temperature. The trick is getting the temperature right from the start, where it needs to be. This design delivers maximum efficiency, but it requires a high level of timing and mastery to achieve optimal ceramic grill temperature control.
The Case for a Big Green Egg Thermometer Upgrade
Is a Big Green Egg Kamado grill thermometer upgrade worth the investment?
The Big Green Egg material is chosen for optimal grilling performance. However, this grilling powerhouse is not without its weak points, though, notably the original dome gauge.
The stock thermometer, while functional, may not deliver the accuracy and consistency needed for precise temperature control. It measures the temperature of the dome, rather than the cooking surface. If you want perfectly cooked meat, rough-guessing the grill’s internal temperature isn’t the way to go.
A feature-rich, modern digital thermometer is what you need to achieve real-time, accurate temperature data. One example is a wireless meat thermometer. It lets you monitor and manage the temperature on your Kamado grill from your smartphone or tablet. It is connected to a probe that monitors the internal meat temperature and the grate or cooking surface. Some models have multiple probes, which is ideal for cooking different types of meats or multi-level cooking.
The convenience of tracking the temperature fluctuations across different meats or surfaces ensures precise grilling. You’ll know exactly when the meat is ready without second-guessing yourself!
Modern digital thermometers feature advanced sensor technology that delivers optimum accuracy. Most thermometers have an accuracy range of ±1°F to ±1.8°F. The hyper-sensitive sensors also enable fast detection of temperature changes. It allows you to adjust your timing, making it suitable for various cooking styles, such as baking or smoking. A reliable tool maximises the versatility and full potential of a Big Green Egg!
Must-Have Kamado Accessories That Work with a Thermometer Upgrade
Are you ready to transform your Kamado grill results from good to professional quality? Here is a detailed look at the must-have Kamado grill accessories that enhance its quality, versatility, and cooking efficiency.
1. Heat Deflectors
There’s no question that Kamado grills are highly versatile. However, they cannot do this on their own. They require proper setup for optimal results, regardless of whether you’re baking, smoking, grilling, or reverse-searing.
Heat deflectors control indirect heat and convection by acting as a barrier between the heat and the food. The ceramic dome provides insulation, while heat deflectors allow even heat distribution. This process also creates more individual cooking zones that sustain longer cooking periods.
Use it in conjunction with an accurate grill thermometer to determine the optimal placement of deflectors for improved temperature management. A ceramic plate setter is one example of a heat deflector for Kamado grills. It is ideal for smoking, baking, and low-and-slow cooking, as it offers even, indirect heat. Some Kamado grill brands already include this as an accessory, but it’s a worthwhile investment if you don’t have one.
A cast-iron griddle is also a notable heat deflector, especially when searing or cooking at high temperatures. For baking, a pizza stone or pizza steel can enhance heat retention and ensure even heat distribution. Both options are excellent for baking pizzas or breads on the Kamado grill.
2. Charcoal Baskets
A charcoal basket is another essential grilling accessory for the Big Green Egg. The basket positions the charcoal to allow tighter, more efficient placement. This setup enables better airflow, ensuring consistent cooking, which is ideal for low-and-slow cooking methods.
Why is proper charcoal placement important in Kamado cooking? It helps to build a more stable fire. When the fire is stable, it means the temperature remains stable. You need this predictability for precise ceramic grill temperature control, especially when cooking for extended periods. A consistent heat source also eliminates unnecessary hot spots that can skew your temperature readings.
3. Airflow Tools
You can do this by adjusting the exhaust vent damper on the top or the air intake vent damper on the bottom. Proper airflow is essential to stabilise the grill’s temperature.
4. Wireless Meat Thermometer Probes
Multiple wireless probes are a lifesaver when cooking with a Kamado grill. It is beneficial when cooking different types of meat, such as ribs, chicken, or brisket.
Depending on the specific model, some thermometers can come with up to six probes. You can insert those probes into each meat, allowing you to track internal temperature changes as the cooking progresses remotely. Some even have modern features that let you enter the target temperature and set an alarm when the meat reaches that temperature.

Choosing the Right Thermometer Upgrade
A Big Green Egg thermometer upgrade isn’t just about ditching the built-in dome thermometer. It unlocks the grill’s full potential for the best results. However, there are numerous options available: which one should you choose?
Wired vs Wireless
The first decision you’ll need to make is whether to choose a wired or wireless thermometer.
Wired thermometers have probe wires that connect to the central display unit. It is a simple setup that offers excellent accuracy in most cases. The downside of wired thermometers is the lack of remote monitoring, so you need to stay close to the grill to check the temperature.
The other option is a wireless thermometer. It utilises Bluetooth to transmit temperature data to a remote device, such as a phone or tablet, within the specified range. These thermometers typically come in a compact design and can send alerts directly to the device, ensuring the food is neither overcooked nor undercooked. The strength of the Bluetooth signal may be affected by the Kamado grill’s thick ceramic walls, so consider this when making your choice.
Temperature Probe Accuracy
Investing in premium components is non-negotiable with thermometers. They are exposed to extreme heat, fire, smoke, and moisture. Anything less than premium could break down easily, resulting in inaccurate readings.
Speaking of accuracy, look for thermometers with an accuracy range of ±1°F to ±1.8°F. Achieving the perfect level of doneness is crucial to ensuring food safety.
Accuracy varies based on the type of sensor used. The best options are those made with high-grade RTD sensors, which are thin and highly responsive, enabling real-time temperature detection.
Aside from temperature accuracy, check the thermometer’s heat resistance. The components must withstand up to 500 degrees F (indirect heat), and the ProTemp S1 can withstand up to 1000 degrees F. The best materials for Kamado cooking techniques are silicone or braided stainless steel. You should steer clear of those made with plastic or cheap rubber components; they are not suitable in high-heat environments.
Professional-Grade
There’s no question: pro-grade thermometers, such as the ProTemp S1, are the best choice for upgrading from a traditional analogue thermometer on the grill dome or other wired models.
Those built-in analogue dome thermometers rely on basic NTC sensors, which can drift by ±10°F or more under heat and smoke, leading to guesswork that risks overcooked brisket or underdone poultry. Wired thermometers aren’t much better—they tether you to the grill with cumbersome wired probes and displays, offering spotty accuracy without the freedom to roam.
The ProTemp S1 changes the game with its lab-calibrated Platinum sensor, delivering ±0.5°F accuracy—10 times sharper than NTC setups. It’s this precision in readings that’s ideal for professional cooking techniques, such as sous vide and searing steaks to exact doneness.
Compared with entry-level options, the ProTemp S1 packs a robust wireless technology suite. Its advanced Bluetooth capability punches through thick ceramic walls without signal dropouts, ensuring real-time readings and alerts straight to your device. It even withstands temps up to 1000°F for those marathon low-and-slow smokes. Plus, features like cloud-synced cook history and estimated cooking times let you nail the perfect temp and timeline, delivering consistent results every time.
But the ProTemp S1 isn’t just a thermometer—it’s your all-in-one controlling hub that turns your grill into a smart setup. Wirelessly connect it to a temperature-controlled fan for automated airflow adjustments and up to four wireless probes to monitor internal meat temps across multiple cuts at once. Everything stays wireless and clutter-free, so your cooking station remains tidy and focused, not tangled in a web of cords.
