Hello! I understand your DreamMapper app isn't showing any readings, and I'd be happy to help you get that sorted out. To get us started, could you please tell me if you’ve tried syncing your device with the app yet and if your Bluetooth on your Windows device is turned on? Also, is your DreamMapper app updated to the latest version? Sometimes syncing issues or outdated app versions can cause readings not to appear.

Once I get a bit more info on what you’ve tried, I can guide you through some steps. Meanwhile, here are some initial things we can check:

1. Check Bluetooth Connection: Make sure Bluetooth is enabled on your Windows PC and that your DreamStation or therapy device is paired with the app.

2. Manual Sync: In the DreamMapper app, look for a sync option—sometimes you'll need to manually trigger the sync by pulling down on the screen or selecting a ‘Sync Now’ button.

3. Date and Time Settings: Ensure your PC’s date, time, and time zone settings are set to automatic, as incorrect settings can prevent data syncing.

4. Update the DreamMapper App: Confirm that your app is updated to the latest version through the Microsoft Store or app source you used.

If those basic steps don’t solve it, we can move to checking device settings and possibly resetting Bluetooth connections.

Could you share which of these you’ve already tried or any other details you've noticed? That way, I can tailor the help better for your Windows setup.
