Hi there! Thanks for reaching out about your sleep tracking showing only 1.5 hours when you actually slept 8 hours. Let's get this sorted out together.

To start, could you tell me if you are using any other sleep apps or devices in conjunction with the Hume Health app, like Apple Health? Also, have you tried syncing your device or app data recently? Sometimes syncing issues can cause discrepancies in sleep data.

Meanwhile, here are some steps to try:

1. Check the App Sync Settings:
Ensure your Hume Health app is properly connected and syncing with any devices or apps that track your sleep (such as Apple Health). Sometimes the data doesn’t update correctly if the connection is broken.

2. Force Sync Your App:
Try closing the Hume Health app completely and reopening it to force a sync. Alternatively, you can try logging out and back into your Hume account.

3. Verify Device Sensors and Placement:
Sleep tracking depends on sensors detecting movement and sometimes heart rate. Make sure your device or any paired hardware (like a smartwatch or body pod) is properly worn and charged overnight.

4. Update the App:
Check the App Store to see if there's an update for the Hume Health app. Sometimes bugs causing inaccurate data are fixed in newer versions.

5. Check for Firmware Updates on Devices:
If you use a device like the Hume Body Pod or a smartwatch, ensure their firmware is up to date, which helps improve tracking accuracy.

If after these steps your sleep still doesn't reflect correctly, please let me know. We can then look deeper into possible app or device issues, or check if there are any ongoing sync problems reported.

Does that sound good? Also, any details you can share about your setup will help me assist you better!
