When charging your probe on the ProTemp Plus Stand, the colored battery icon on the screen will display an animation. Once fully charged, the icon will show as full and flash, indicating the probe is ready for at least 30 hours of use. If you are not sure if the probe has been fully charged or if it is unable to be charged, please go to My Connections>>My Paired Probes>>Tap it to check its battery. If the probe isn’t charging properly, please try the following:

1. Clean the remaining grease on the probe before charging.
2. Adjust the metal plate in the Stand’s charging slot to ensure proper contact with the probe: Fix Your Plus Charging Stand: Solve Loose Contact Issues Fast!
3. Restart the stand, then place the probe in another slot to charge it. (Both the front and back slots can be used to charge the probe.)

If the issue persists, please try these steps:

• Download the LightBlue app and check if “Probe” appears in the device list. Each charged probe should display as a separate entry.
• Record a short video showing the probe charging and send it to [email protected]. We’ll review it promptly and resolve the issue.

To verify if your probe is charging correctly on the 4-in-1 Charger, please check the following:

1. Charging Indicator: A blue light will appear at the corresponding charger slot when the probe is charging. The light will turn off once the probe is fully charged, indicating it’s ready for at least 30 hours of use.
2. Probe Orientation: Ensure the probe is inserted correctly, with its tail making full contact with the metal plate in the charger’s slot. Place the probe in another slot to charge it.

If you are not sure if the probe has been fully charged or if it is unable to be charged, please go to My Connections>>My Paired Probes>>Tap it to check its battery. If the issue persists, please try these steps:

• Download the LightBlue app and check if “Probe” appears in the device list. Each charged probe should display as a separate entry.
• Record a short video showing the probe charging and send it to [email protected]. We’ll review it promptly and resolve the issue.

Please note that the 4‑in‑1 Probe Charger is designed solely for charging multiple wireless probes at the same time—up to four. The wireless probes cannot connect directly to the app; they must be paired with our smart thermometers, such as the ProTemp S1 or the ProTemp Plus Series. You can watch the probe tutorial here: How to Add a Wireless Probe to ProTemp S1 & Charge It with the 4-in-1 Charger. If your probe cannot be added via the app, please check the following steps:

• Ensure your thermometer is turned on, and place it close to the probe so it can receive and transmit the signal properly.
• Before adding a probe, also ensure your thermometer is connected to Wi‑Fi through the app. The Wi‑Fi icon on the display should be solid (not flashing).
• Confirm that your probe is fully charged. When connecting, remove it from the ProTemp Plus Stand or 4‑in‑1 Charger, as Bluetooth cannot be detected while the probe is charging in the slot.
• Please note that each probe can only be connected to one thermometer at a time (either ProTemp S1 or ProTemp 2 Plus).

If you are unsure about the probe’s pairing status, please delete all connections in the app, exit and restart your app, reconnect your thermometer, and then re‑add the probe.

Please remove the fully-charged probe from the Charger or Plus Stand, and insert it into the slot again to activate it.

To ensure optimal performance, please kindly check the following:

1. When inserting the probe, make sure the tip goes past the safety line, but avoid placing the meat too close to the tail end.
2. The tail end of the probe should not come into contact with the grill or any other surfaces.
3. We recommend disconnecting all connections in the app and then reconnecting the probe to check.

If the problem continues, please send us relevant screenshots, photos, or videos showing the issue. This will help us analyze the situation more accurately and provide a solution as quickly as possible.

If your S1 does not display temperature data or display LLL, we recommend that you confirm whether the S1 Main Unit is correctly installed on the Base Unit and ensure that all contact points between the Main Unit and the Base Unit are in normal contact. You can watch our tutorial video to install it: ProTemp S1 Installation.

You can also reset S1 by pressing the RESET button next to the charging port to see if it can fix the issue. If it still fails, please take a video of the installation progress and send it to [email protected], and we will check and provide you with a solution.

To ensure safe and effective charging for your S1, please kindly note the following:

• Keep ports dry: Before charging, make sure both the S1’s charging port and the charging cable are completely dry and free from moisture or oil.
• Avoid heat exposure: Do not charge the S1 on surfaces that have not fully cooled down, such as recently used stoves. Prolonged exposure to residual heat may compromise device safety.
• Charge before use: Ensure the S1 is fully charged prior to operation. Do not charge the device while it is actively being used on a grill.
• Use the original power sources: Always use the original charging block. Additionally, you can use a 5V⎓2A DC adapter and a Type-C charging cable.
