3 [![REUSE status](https://api.reuse.software/badge/github.com/SAP/e-mobility-charging-stations-simulator)](https://api.reuse.software/info/github.com/SAP/e-mobility-charging-stations-simulator)
7 Simple [node.js](https://nodejs.org/) software to simulate a set of charging stations based on the OCPP-J 1.6 protocol as part of SAP e-Mobility solution.
13 - [Chocolatey](https://chocolatey.org/):
16 choco install -y nodejs-lts
21 - [Homebrew](https://brew.sh/):
29 - [NodeSource](https://github.com/nodesource/distributions) Node.js Binary Distributions for version 16.X
31 ## Configuration files syntax
33 All configuration files are in the JSON standard format.
35 **Configuration files list**:
37 - charging stations simulator configuration: [src/assets/config.json](src/assets/config.json);
38 - charging station configuration templates: [src/assets/station-templates](src/assets/station-templates);
39 - charging station configurations: [dist/assets/configurations](dist/assets/configurations);
40 - charging station RFID tags lists: [src/assets](src/assets).
42 The charging stations simulator's configuration parameters must be within the `src/assets/config.json` file. A charging station simulator configuration template file is available at [src/assets/config-template.json](src/assets/config-template.json).
44 All charging station configuration templates are in the directory [src/assets/station-templates](src/assets/station-templates).
46 A list of RFID tags must be defined for the automatic transaction generator with a default location and name: `src/assets/authorization-tags.json`. A template file is available at [src/assets/authorization-tags-template.json](src/assets/authorization-tags-template.json).
48 **Configuration files hierarchy and priority**:
50 1. charging station configuration: [dist/assets/configurations](dist/assets/configurations);
51 2. charging station configuration template: [src/assets/station-templates](src/assets/station-templates);
52 3. charging stations simulator configuration: [src/assets/config.json](src/assets/config.json).
54 The charging stations simulator have an automatic configuration files reload feature at change for:
56 - charging stations simulator configuration;
57 - charging station configuration templates;
58 - charging station authorization RFID tags lists.
60 But the modifications to test have to be done to the files in the build result directory [dist/assets](dist/assets). Once the modifications are finished, they have to be reported or copied to the matching files in the build source directory [src/assets](src/assets) to ensure they will be taken into account at next build.

228 ### Charging station configuration
230 **dist/assets/configurations/\<hashId\>.json**:
232 The charging station configuration file is automatically generated at startup from the charging station configuration template file and is persistent.
234 The charging station configuration file content can be regenerated partially on matching charging station configuration template file changes. The charging station serial number is kept unchanged.
236 #### stationInfo section
238 The syntax is similar to charging station configuration template with some added fields like the charging station id (name) and the 'Configuration' section removed.
240 #### configurationKey section
242 The syntax is similar to the charging station configuration template 'Configuration' section.
246 To start the program, run: `npm start`.
248 To start the program with a UI controller, run: `npm start:server`.
249 Then, start/stop the simulator by going to `https://<hostname:port>` in a browser. Localhost port will default to 8080. For Cloud Foundry, the port is assigned based on the `process.env.PORT` environment variable.
253 In the [docker](./docker) folder:
