Arthexis Constellation is a Django-based software suite that centralizes tools for managing electric vehicle charging infrastructure and orchestrating energy-related products and services.

Visit our Changelog Report to browse past and future features and other updates.

• 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.

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

• 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.

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 to install with defaults, start the server with ./start.sh (optionally passing --reload or --celery), and execute a quick smoke test with pytest -k smoke. Override the role, port, reload, Celery, and test selection with the script flags when needed.

• 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.

• Linux:

  • Run ./install.sh --terminal to bootstrap a default Terminal node (pass --control, --satellite, or --watchtower as needed). Override the port with --port 8888 (the default fallback) and control Celery with --celery or --no-celery. Use ./install.sh --help to see every available option.
  • Use ./upgrade.sh with --stable (weekly) or --latest/-l/--unstable (daily) to follow the preferred release cadence.
  • Consult the Install & Lifecycle Scripts Manual for complete flag descriptions and operational notes.
  • Review the Auto-Upgrade Flow for how delegated upgrades run and how to observe them.

• Windows:

  • Run install.bat to install (Terminal role) and upgrade.bat to upgrade.
  • To run as a background service, install NSSM and use service.bat install --name arthexis (add --port if needed).
  • Installation is not required to start in Terminal mode (the default).

Upgrade channels (opt-in during install/upgrade or with scripts/delegated-upgrade.sh):

• 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 feature rollout strategies using the Node Features Cookbook.
• Curate shortcuts for power users through the Favorites Cookbook.
• Connect Slack workspaces through the Slack Bot Onboarding Cookbook.

Arthexis Constellation is still under very active development and new features are added every day.
