6. Troubleshooting
- Device not connecting to Wi-Fi:
- Ensure your Wi-Fi network is 2.4GHz. The device does not support 5GHz networks.
- Verify the Wi-Fi password is entered correctly in the app.
- Make sure the device is within range of your Wi-Fi router.
- Restart the device by removing and reinserting the batteries, then try the pairing process again.
- Inaccurate Temperature Readings:
- Ensure the probe is properly positioned and not obstructed.
- Allow sufficient time (e.g., 30 minutes) for the probe to stabilize to the ambient temperature of the appliance.
- Calibration: If you suspect consistent inaccuracy, the probe temperature can be calibrated via the Smart Life app.
- In the app, tap the list icon in the upper-right corner of the device page, then select "Setting".
- Find "Probe Temp Calibration" and adjust the value as needed.
- Confirm the changes.

- No App Notifications:
- Check if temperature alert ranges are correctly set in the app.
- Ensure your phone's notification settings allow alerts from the Smart Life app.
- Verify the device is connected to Wi-Fi and reporting data.
- Limited Account Access: The device can typically be added to one primary Smart Life account. Sharing access with other family members may require specific app features or workarounds, which can vary by app version.
