ProTemp S1

For optimal performance and longevity, we recommend placing both the S1 thermometer and the Breezo control fan in environments where the temperature stays within safe operating limits.

• Minimum temperature: Avoid prolonged exposure below 32°F (0°C), as this may significantly reduce battery life and affect overall functionality.
• Maximum temperature: The fan is heat-resistant up to 302°F (150°C), while the S1 thermometer is rated for up to 140°F (60°C).

Given that winter temperatures can dip below the recommended minimum, and high-heat cooking zones may exceed safe limits, we advise using the product in a protected or temperature-controlled setting to ensure reliable operation. Proper placement and shielding will help extend the life of your device and maintain accurate performance.

The ProTemp S1 is designed to fit almost all grills and smokers on the market. Simply remove your existing gauge thermometer and replace it with the S1, or drill a new hole if needed(do not drill ceramic).

There are 4 different variants of the ProTemp S1.

Universal Version: This model has a base stem diameter of 7.8 mm (0.3 inches) and is compatible with most grills and smokers, including Weber, Kamado Joe (except Big Green Egg), drum, offset, and kettle grills. It’s ideal if your grill’s gauge hole is approximately 0.3 inches or larger.

BGE Version: Designed specifically for Big Green Egg grills or other grills with smaller gauge holes like Primo Oval XL, this version has a thinner base stem diameter of 4.1 mm (0.16 inches). It’s perfect for Big Green Egg, Primo Oval XL, or similar grills with smaller ports (For the Primo XL series, since the thermometer hole diameter may vary depending on the production year, it is recommended to measure the diameter of the thermometer hole before purchasing the ProTemp S1).

5.5” Special Edition: Its base stem diameter is the same as the Universal Version, at 7.8 mm (0.3 inches), but its stem length is longer, at 5.5 inches, making it suitable for devices where the thermometer is farther from the food, like Old Country Gravity Fed smoker.

1.5″ Short Stem Edition: Retaining the same base stem diameter as the Universal Version, at 7.8 mm (0.3 inches). This model features a shorter 1.5-inch stem. The reduced length ensures better compatibility with grills requiring limited internal clearance, preventing interference with lid operation. It’s particularly well-suited for certain gas grills, such as the Weber Genesis and Napoleon Prestige PRO series.

We recommend measuring the gauge hole on your grill to ensure the perfect fit before choosing a version.

No need if your grill has an analog thermometer—just replace it. If there’s no hole (like on some offset smokers), you can drill one. Just skip drilling on ceramic grills.

The Base Unit of ProTemp S1 is fully waterproof. However, the Main Unit has an IP54 rating, which provides limited protection against dust and splashing water. Please avoid exposing the unit to water. For enhanced protection, we recommend installing the optional ProTemp S1 Waterproof Silicone Protective Cover (sold separately).

Although the probe is waterproof, it cannot be washed in a dishwasher, as this can cause damage to the internal sensors of the probe (as mentioned in the manual).

No. The ProTemp S1 does more than just read dome temp. We use platinum sensors for 10x accuracy over analog, a long stem to get closer to grate level, and a temp compensation function in the app. Our tests show just a 3-5°F difference from a wired grate-level probe in Kamado grill before app compensation.

If you experience connection issues with your probes (can not connect the probes to ProTemp S1/ProTemp Plus Series, or the probe is disconnected during use), please try the following step-by-step guide:

1. Delete all your connection in the app, including ProTemp S1, ProTemp Plus/ProTemp 2 Plus and probes.
2. Uninstall the ChefsTemp app and reinstall it, ensure that your app is the latest version.
3. Fully charge everything: Place all probes in the 4-in-1 Charger or ProTemp Plus/ProTemp 2 Plus Stand for at least 15 minutes.
4. Pair probes one at a time: Take only one probe out of the Charger/Stand to pair. Wait for it to connect successfully, then put it back, and repeat with the next probe (Click on “…” in the upper right corner of the app homepage, click on “My Connections”, click on “Add New Probe”, and then click on “Probe” in “SEARCHING FOR NEARBY PROBES”).
5. Ensure that your ProTemp S1 and ProTemp Plus/ProTemp 2 Plus Stand are located close to the probe to ensure smooth transmission of probe signals.

This method avoids signal interference between probes and helps the app detect them correctly.

If your probe still cannot connect, you can perform the following confirmation steps:

1. Click on the probe icon on the probe page to perform fault diagnosis. You can watch this video to perform the operation: New ChefsTemp App Update Guide | How to Diagnose Disconnection Issues
2. After charging the probes, remove them from the Charger/Stand, download and open the LightBlue app, search for “Probe”, and see if you can find them. Each charged and removed probe will display a line of “Probe”.
3. Please take a video of your complete connection operation, screenshots of the app homepage and diagnostic information, as well as LightBlue screenshots and send them to us. We will analyze and provide a solution for you.

Please watch our tutorial video to ensure you’re following the correct Wi-Fi setup process: How to Pair Your ProTemp S1 with Bluetooth and Wi-Fi | Step-by-Step.

If you are still stuck on the Wi-Fi connection step, please check the following tips:

• 1. Confirm the Wi-Fi icon on your S1 screen is solid (not flashing). A missing icon indicates Wi-Fi is off, while a flashing icon suggests an unstable connection.
• 2. Check App Permissions: Make sure the ChefsTemp app has all required permissions—especially location access—enabled on your device.
• 3. Check Wi-Fi Settings: Ensure your Wi-Fi is on a 2.4GHz network. If 5GHz Wi-Fi only, simply create a guest 2.4GHz Wi-Fi network in the router app, making it easier for smart devices to join.
• 4. Password and SSID: Use the orange magnifying glass to auto-detect the SSID, and double-check that the Wi-Fi password is entered correctly, as spell-check may alter it.
• 5. Router Settings: Disable fast roaming (e.g., 802.11r) on your router, as it may prevent the S1 from connecting.

When charging your S1, a charging animation will appear on the battery icon. A flashing, fully charged icon indicates the S1 is completely charged. A fully charged S1 provides at least 40 hours of usage. For optimal charging, use the original charging cable with a power source not exceeding 20W.

Remove the S1 Main Unit from the Base first, then charge the S1 Main Unit. Do not charge ProTemp S1 on cooking equipment!

If your S1 isn’t fully charging or has a short battery life, try the following:

1. Use a different power supply and charging cable, then recharge the device.
2. Ensure your S1 firmware is updated to the latest version.
3. Reset S1 by press the RESET Button next to the S1 charging port

If it still fails, please send a video of the issue (showing the charging progress) to our support e-mail: info@chefstemp.com, we will help you further.

After using the ProTemp S1, the water droplets inside are most likely caused by condensation.

The main unit has an IP54 waterproof rating, which means it is protected against dust and light splashes of water, but it is not fully waterproof. During cooking, the high temperature and humidity inside the grill cause moisture to enter through small gaps. When the unit cools down quickly to room temperature, the moisture condenses into water droplets inside.

How to handle it:

• Remove the main unit and place it in a warm, dry, well-ventilated area. Let it dry naturally.
• Wait until it is completely dry before using or charging it again.

To prevent this in the future, remove the main unit from the grill after cooking and store it indoors. Avoid leaving it in the grill while it cools down rapidly.

If the problem happens repeatedly or the device stops working after drying, please contact ChefsTemp Customer Support at info@chefstemp.com for assistance.

The ProTemp S1 is designed to replace the original grill thermometer, providing reference temperature data. Since temperature differences within various areas of the grill/smoker can be significant, sometimes varying by over 100°F, we recommend installing the ProTemp S1 in the original thermometer port for more accurate readings.

If your grill/smoker does not have a thermometer port, you may need to create one and position the ambient probe of ProTemp S1 closer to the meat for more accurate temperature measurements.

If there are still issues, please contact our customer service via phone or email for support.
