If your S1 is not displaying probe temperature data, please verify the following:

1. The probe is securely connected to the S1.
2. The probe is fully charged.
3. The probe channel displayed on the S1 matches the channel where the probe is connected.

You can also try disconnecting all connections in the app and reconnecting to see if the issue persists. If the problem continues, please record a short video demonstrating the issue.
