4.1. Charging the Probe
Insert the probe into the charging dock. The battery charge indicator on the charging dock will be red when charging and turn off when fully charged. The probe fully charges in approximately 30 minutes.

4.2. App Installation
Download the official Tempwise app from your smartphone's app store (available for Android and iOS devices). Ensure your phone's Bluetooth is enabled.
4.3. Bluetooth Pairing
Open the Tempwise app on your smartphone. The app will guide you through the pairing process. Ensure the probe is charged and within Bluetooth range of your device. The thermometer uses Bluetooth LE5.0 for connection.
5. Operating Instructions
5.1. Inserting the Probe
Carefully insert the probe into the thickest part of the meat, avoiding bones. It is crucial to insert the probe deep enough so that the internal temperature sensor is fully within the meat and beyond the safety line marked on the probe. This ensures accurate internal temperature readings.

5.2. Using the App
Once the probe is inserted and connected via Bluetooth:
- Select Food Type: In the app, choose the type of food you are cooking from the 23 USDA presets or create a custom preset.
- Set Target Temperature: Adjust the target internal temperature and desired doneness (e.g., rare, medium, well-done).
- Set Alarms and Timer: You can set a temperature pre-alarm to notify you when the meat is approaching its target temperature, and a cooking timer for overall duration.
- Monitor Progress: The app will display real-time internal and ambient temperatures. You will receive notifications on your smartphone when the target temperature is reached or if a pre-alarm is triggered.
6. Maintenance
6.1. Cleaning
The probe has an IP67 waterproof rating, making it easy to clean. It is also dishwasher safe. Ensure the probe is thoroughly cleaned after each use to prevent bacterial growth and maintain hygiene.
6.2. Storage
Store the probe and charging base in a dry, cool place when not in use. Keep them away from extreme temperatures and direct sunlight to prolong their lifespan.
7. Troubleshooting
- No Temperature Reading: Ensure the probe is fully inserted into the meat beyond the safety line. Check if the probe is charged and properly connected to the app via Bluetooth.
- App Connectivity Issues: Verify your smartphone's Bluetooth is on and the app has necessary permissions. Ensure you are within the 30m/98ft Bluetooth range. Restarting the app or your phone may resolve minor connection glitches.
- Inaccurate Readings: Calibrate the thermometer if you suspect inaccuracies. The calibration range is -7℃~+7℃/-12.6℉~+12.6℉.
- Where can I use it? The thermometer is suitable for various cooking environments including ovens, grills, and barbecues.
- Where can I place it? You can place the charging base and your monitoring device anywhere within the Bluetooth connection range.
8. User Tips
- Always ensure the probe is inserted past the safety line for accurate internal temperature readings.
- Utilize the USDA presets for common meats to ensure optimal doneness without guesswork.
- Take advantage of the pre-alarm and timer functions to avoid overcooking and achieve perfect results.
- Monitor cooking progress remotely via the app, allowing you to attend to other tasks or guests without constantly checking the food.
- The thermometer requires one AAA battery for the charging base.
