3.3. Real-Time Temperature Chart
The eWeLink app records the temperature detected by the probes and generates a real-time temperature chart. This feature allows you to track temperature changes throughout the cooking process, providing valuable insights for consistent results.
3.4. Timer Reminder
Utilize the timer function in the eWeLink app to set a resting period for your freshly cooked meat. Once the timer concludes, you will receive a reminder, ensuring your meat rests properly before serving for optimal tenderness and flavor.

5. Troubleshooting
If you encounter issues with your SONOFF BMT01, refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not powering on. | Dead or incorrectly installed batteries. | Replace batteries with new AAA batteries, ensuring correct polarity. Check if the battery insulation sheet has been removed. |
| Cannot connect to eWeLink app. | Wi-Fi/Bluetooth issues, incorrect password, device too far from router/phone. | Ensure phone's Bluetooth and Wi-Fi are on. Verify Wi-Fi password. Move device closer to router/phone. Restart the thermometer and try pairing again. Ensure you are using a 2.4GHz Wi-Fi network. |
| Inaccurate temperature readings. | Probe not fully inserted, damaged probe, or probe not calibrated (though typically not user-calibrated). | Ensure probes are fully inserted into the meat and the thermometer unit. Check probes for visible damage. Test probes in boiling water (212°F/100°C) or ice water (32°F/0°C) for approximate accuracy. |
| No alerts received. | App notifications disabled, device not connected, or target temperature not set. | Check app notification settings on your phone. Ensure the thermometer is connected to the app. Verify that a target temperature has been set for the active probe. |
If the problem persists, please contact SONOFF customer support for further assistance.
