In the AirGradient admin section you can setup groups. You can reach the Place Administration with the hamburger menu or via https://app.airgradient.com/settings/place . Please note that this administration menu is ONLY available for administrators.
Larger organisations e.g. schools or companies might have different sections that they want to see separated in the AirGradient dashboard and reports. For these Groups can be set up here.
Then under Locations above, a location can be assigned to a specific group.
