Hi there! I'm sorry to hear that your Letsfit E27 isn't showing the weather. I can help you troubleshoot this. Here are a few things we can check together:

1. Check Bluetooth Connection: Ensure your smartwatch is properly paired with your phone. Go into your phone’s Bluetooth settings and confirm that the Letsfit E27 is connected.

2. App Permissions: Open the Letsfit app on your phone and check if it has permission to access location services. The weather feature typically requires this to provide accurate data.

3. Weather Settings: Within the Letsfit app, navigate to the settings where you can find the weather feature. Make sure that weather services are turned on and that you’ve selected the correct location.

4. App Update: Sometimes, issues arise due to outdated applications. Please check for any updates in the app store for the Letsfit app and install them.

5. Restart Devices: Restart both your smartwatch and phone. This simple step can often resolve connection issues.

6. Re-pair Watches: If the above steps don't work, try unpairing the watch from your phone and then re-pairing it.

Please go through these steps and let me know if the weather feature starts working! Are you satisfied with the solution I provided? If the issue persists, we can dive deeper.
