Hi,

Odoo’s Fleet Management app is web-based and requires an internet connection, so it does not natively support offline operation. This can be a challenge for environments like mining sites where there is no cellular or Wi-Fi connectivity.

To achieve offline functionality, options include developing a custom mobile or tablet app that stores data locally and syncs with the Odoo server when connectivity is available, or deploying a local Odoo instance on-site with periodic synchronization to the main database. Both approaches require custom development and careful handling of data conflicts.

Hope it helps
