Welcome to the nymea EV-Dash experience plugin repository. Please keep the following guidelines in mind when working on this codebase:
## Purpose
The dashboard should should give an overview of conofugred ev chargers in the system, show the status of each ev charger, information and provide
## Structure
- The `plugin` directory contains the Qt c++ implementation of the experience plugin
- The `EvDashJsonHandler` class provides the JSON RPC API definition and declaration of the experience
- The `EvDashWebServerResource` represents the webserver HTTP backend and handles REST API requests and file requests starting with the path /evdash
- The `dashboard` folder contains the webinterface, a html + javacript based website representing the frontend.
- The `EvDashWebServerResource` represents the webserver HTTP backend and handles REST API requests and file requests starting with the path /evdash. This class provides file access to the static resources and provides secure generated data access
- The `dashboard` folder contains the webinterface, a html + js file based website representing the frontend. The interface will be compiled into the plugin using the dashboard.qrc file.
- The dashboard should be brandable, providing 3 colors and icons should allow to change the style of the webinterface
- The dashboard uses a websocket to communicate with the API interface in `EvDashEngine`.
## General workflow
- Keep pull request descriptions concise but informative, mentioning both user-visible changes and internal refactors.
