   7 ## Summary
   8
   9 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.
  10
  11 ## Prerequisites
  12
  13 Install the [node.js](https://nodejs.org/) LTS runtime environment:
  14
  15 ### Windows
  16
  17 - [Chocolatey](https://chocolatey.org/):
  18
  19 ```powershell
  20 choco install -y nodejs-lts
  21 ```
  22
  23 ### MacOSX
  24
  25 - [Homebrew](https://brew.sh/):
  26
  27 ```shell
  28 brew install node@16
  29 ```
  30
  31 ### GNU/Linux
  32
  33 - [NodeSource](https://github.com/nodesource/distributions) Node.js Binary Distributions for version >= 16.X
  34
  35 ## Installation
  36
  37 In the repository root, run the following command:
  38
  39 ```shell
  40 npm install
  41 ```
  42
  43 ## Initial configuration
  44
  45 Copy the configuration template file [src/assets/config-template.json](src/assets/config-template.json) to [src/assets/config.json](src/assets/config.json).
  46 Copy the authorization RFID tags template file [src/assets/authorization-tags-template.json](src/assets/authorization-tags-template.json) to [src/assets/authorization-tags.json](src/assets/authorization-tags.json).
  47
  48 Tweak them to your needs by following the section [configuration files syntax](README.md#configuration-files-syntax).
  49
  50 ## Start
  51
  52 To start the program, run: `npm start`.
  53
  54 ## Start Web UI
  55
  56 See Web UI [README.md](ui/web/README.md) for more information.
  57
  58 ## Configuration files syntax
  59
  60 All configuration files are in the JSON standard format.
  61
  62 **Configuration files locations**:
  63
  64 - charging stations simulator configuration: [src/assets/config.json](src/assets/config.json);
  65 - charging station configuration templates: [src/assets/station-templates](src/assets/station-templates);
  66 - charging station configurations: [dist/assets/configurations](dist/assets/configurations);
  67 - charging station RFID tags lists: [src/assets](src/assets).
  68
  69 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).
  70
  71 All charging station configuration templates are in the directory [src/assets/station-templates](src/assets/station-templates).
  72
  73 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).
  74
  75 **Configuration files hierarchy and priority**:
  76
  77 1. charging station configuration: [dist/assets/configurations](dist/assets/configurations);
  78 2. charging station configuration template: [src/assets/station-templates](src/assets/station-templates);
  79 3. charging stations simulator configuration: [src/assets/config.json](src/assets/config.json).
  80
  81 The charging stations simulator have an automatic configuration files reload feature at change for:
  82
  83 - charging stations simulator configuration;
  84 - charging station configuration templates;
  85 - charging station authorization RFID tags lists.
  86
  87 But the modifications to test have to be done to the files in the build target 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.

 272 ### Charging station configuration
 273
 274 **dist/assets/configurations/\<hashId\>.json**:
 275
 276 The charging station configuration file is automatically generated at startup from the charging station configuration template file and is persistent.
 277
 278 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.
 279
 280 #### stationInfo section
 281
 282 The syntax is similar to charging station configuration template with some added fields like the charging station id (name) and the 'Configuration' section removed.
 283
 284 #### configurationKey section
 285
 286 The syntax is similar to the charging station configuration template 'Configuration' section.
 287
