Hi! I understand that the "sun energy" or solar energy display is missing on your FoxCloud2.0 app’s start screen. Let's see how we can get that back for you.

Just to clarify before we begin, is the rest of the app functioning normally? For example, are you able to see other data like load, grid, or battery info? Also, have you recently updated the app or made any changes to your system hardware or network?

Meanwhile, here are some steps we can try to restore the sun energy display:

1. Restart the App: Close the FoxCloud2.0 app completely and reopen it. This can sometimes refresh the data display.

2. Check for App Updates: Go to your app store and ensure you have the latest version of FoxCloud2.0 installed. Updates often fix display and data sync issues.

3. Verify Network Connectivity: Make sure your device is connected to the internet and the Fox inverter or solar system is also online. Sometimes the app may not show solar data if it can't communicate with the system.

4. Re-login or Sync: Try logging out of the app and logging back in. This can force the app to sync fresh data from your system.

5. Reset Wireless Dongle (if applicable): Some users have resolved similar display issues by unplugging the wireless dongle from the inverter and plugging it back in, which restarts the radio communication.

6. Check System Status: If possible, verify via your solar installer or monitoring portal that your solar panels and inverter are functioning properly and sending data to FoxCloud2.0.

If after these steps the sun energy data is still missing, it could be related to a temporary app or server issue. The FoxCloud2.0 service sometimes undergoes maintenance that temporarily affects data like solar output display.

Could you please try these steps and let me know the outcome? Also, if there are any error messages or unusual signs within the app, please share those details with me. That will help me guide you further!
