This refactoring streamlines how IoT Boxes communicate with Odoo databases across delivery, POS, manufacturing, and self-order workflows. It should make device connectivity easier to maintain and more consistent, reducing future complexity without introducing a new business feature.

The communication between the IoT Box and a DB can be:
- Longpolling,
- Websocket,
- Simple fetch from one side or the other.

We refactored all this in order to simplify the communication.
