Asset Management

Asset Type

The app creates a Weather asset type that represents weather monitoring locations.

Creating Weather Assets

1. Navigate to Assets in Eliona.

2. Click on "Create new asset."

4. Configure the basic asset properties.

5. Save the new asset.

Location Configuration

1. Open your Weather asset.

2. Click the edit button.

3. In the "Additional Information" section:

   • Enter the location name (e.g., "Zurich, Switzerland").

   • For best results, use the format: "City, Country" or "City, State, Country."

4. Save the configuration.

5. Refresh the page to check:

   • The location name appears with additional geographic details.

   • Weather data begins to populate the asset attributes.

Location Troubleshooting

If the location is not found:

1. Try more specific location names.

2. Add country or state information.

3. Check if the location exists in the OpenWeatherMap database.

4. Check for typos in the location name.
