Suite Features

• Compatible with the Open Charge Point Protocol (OCPP) 1.6 by default, while allowing Charging Stations to upgrade to newer protocols if they support them.

Role Architecture

Arthexis Constellation ships in four node roles tailored to different deployment scenarios.

[!NOTE] Terminal is the default role and keeps environment-changing capabilities disabled by default. Other roles may enable host-level features (such as networking changes or background services), so choose them only when those capabilities are needed.

Quick Guide

1. Clone

• Linux: open a terminal and run git clone https://github.com/arthexis/arthexis.git.
• Windows: open PowerShell or Git Bash and run the same command.

For preloaded environments without Git remotes configured, see the remotes note in the Install & Lifecycle Scripts Manual.

2. Start and stop

Terminal nodes can start directly with the scripts below without installing; Control, Satellite, and Watchtower roles require installation first. Both approaches listen on localhost:8888 by default.

For local bootstrapping, run ./install.sh --terminal, start the server with ./start.sh, and run a quick smoke test with pytest -k smoke. For full runtime options and advanced usage, refer to the Install & Lifecycle Scripts Manual.

• VS Code
  • Open the folder and go to the Run and Debug panel (Ctrl+Shift+D).
  • Select the Run Server (or Debug Server) configuration.
  • Press the green start button. Stop the server with the red square button (Shift+F5).

• Shell
  • Linux: run ./start.sh and stop with ./stop.sh.
  • Windows: run start.bat and stop with stop.bat.

3. Install and upgrade

• Linux: run ./install.sh --terminal (or another role preset) and use ./upgrade.sh for updates.
• Windows: run install.bat and upgrade.bat.

Detailed install flags, service-management choices, and upgrade-channel behavior are documented in:

• Install & Lifecycle Scripts Manual
• Auto-Upgrade Flow

4. Administration

• Access the Django admin at localhost:8888/admin/ to review and manage live data. Use --port with the start scripts or installer when you need to expose a different port.
• Browse the admindocs at localhost:8888/admindocs/ for API documentation that is generated from your models.
• Follow the Install & Administration Guide for deployment, lifecycle tasks, and operational runbooks.
• Onboard and service chargers with the EVCS Connectivity & Maintenance Cookbook.
• Configure payment gateways with the Payment Processors Cookbook.
• Reference the Sigils Cookbook when configuring tokenized settings across environments.
• Understand seed fixtures and per-user files with Managing Local Node Data.
• Manage exports, imports, and audit trails with the User Data Cookbook.
• Plan node capability adoption and configuration using the Node Features Cookbook.
• Curate shortcuts for power users through the Favorites Cookbook.
• Connect Slack workspaces through the Slack Bot Onboarding Cookbook.

5. Development

• Browse the Developer Documentation Library for architecture references, protocol manuals, and contribution workflows.
• Command convention:
  • Default to .venv/bin/python manage.py ... for Django and developer tasks.
  • Prefer ./command.sh ... (or command.bat ... on Windows) for operational tasks when an instance is already up.
  • Keep using dedicated scripts (for example install.sh, start.sh, upgrade.sh) when a task has a specific lifecycle entrypoint.
