8## Summary
9
10Simple [node.js](https://nodejs.org/) software to simulate and scale a set of charging stations based on the OCPP-J 1.6 protocol as part of SAP e-Mobility solution.
11
12## Prerequisites
13
14Install the [node.js](https://nodejs.org/) current LTS or superior version runtime environment:
15
16### Windows
17
18- [Chocolatey](https://chocolatey.org/):
19
20```powershell
21choco install -y nodejs
22```
23
24### MacOSX
25
26- [Homebrew](https://brew.sh/):
27
28```shell
29brew install node
30```
31
32### GNU/Linux
33
34- [NodeSource](https://github.com/nodesource/distributions) Node.js Binary Distributions for version >= 16.X
35
36## Installation
37
38Enable corepack if not already done and install latest pnpm version:
39
40```shell
41corepack enable
42corepack prepare pnpm@latest --activate
43```
44
45In the repository root, run the following command:
46
47```shell
48pnpm install
49```
50
51## Initial configuration
52
53Copy the configuration template file [src/assets/config-template.json](src/assets/config-template.json) to [src/assets/config.json](src/assets/config.json).
54Copy the RFID tags template file [src/assets/idtags-template.json](src/assets/idtags-template.json) to [src/assets/idtags.json](src/assets/idtags.json).
55
56Tweak them to your needs by following the section [configuration files syntax](README.md#configuration-files-syntax).
57
58## Start
59
60To start the program, run: `pnpm start`.
61
62## Start Web UI
63
64See Web UI [README.md](ui/web/README.md) for more information.
65
66## Configuration files syntax
67
68All configuration files are in the JSON standard format.
69
70**Configuration files locations**:
71
72- charging stations simulator configuration: [src/assets/config.json](src/assets/config.json);
73- charging station configuration templates: [src/assets/station-templates](src/assets/station-templates);
74- charging station configurations: [dist/assets/configurations](dist/assets/configurations);
75- charging station RFID tags lists: [src/assets](src/assets).
76
77The 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).
78
79All charging station configuration templates are in the directory [src/assets/station-templates](src/assets/station-templates).
80
81A list of RFID tags must be defined for the automatic transaction generator in a file with a default location and name: `src/assets/idtags.json`. A template file is available at [src/assets/idtags-template.json](src/assets/idtags-template.json).
82
83**Configuration files hierarchy and priority**:
84
851. charging station configuration: [dist/assets/configurations](dist/assets/configurations);
862. charging station configuration template: [src/assets/station-templates](src/assets/station-templates);
873. charging stations simulator configuration: [src/assets/config.json](src/assets/config.json).
88
89The charging stations simulator have an automatic configuration files reload feature at change for:
90
91- charging stations simulator configuration;
92- charging station configuration templates;
93- charging station authorization RFID tags lists.
94
95But 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.

325### Charging station configuration
326
327**dist/assets/configurations/\<hashId\>.json**:
328
329The charging station configuration file is automatically generated at startup from the charging station configuration template file and is persistent.
330
331The 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.
332
333#### stationInfo section
334
335The syntax is similar to charging station configuration template with some added fields like the charging station id (name) and the 'Configuration' section removed.
336
337#### configurationKey section
338
339The syntax is similar to the charging station configuration template 'Configuration' section.
340

461## UI protocol
462
463Protocol to control the simulator via a Websocket or HTTP server.
464
465### HTTP Protocol
466
467To learn how to use the HTTP protocol to pilot the simulator, an [Insomnia](https://insomnia.rest/) HTTP requests collection is available in [src/assets/ui-protocol](./src/assets/ui-protocol) directory.
468
469### Websocket Protocol
470
471SRPC protocol over Websocket. PDU stands for 'Protocol Data Unit'.
472
473- Request:
