Installer and Packs (spx-examples)

Use the spx-examples installer to assemble a ready-to-run bundle of models, services, and optional UI.

Use the spx-examples installer when you want a complete, ready-to-run bundle: selected models, supporting services (MQTT, BACnet, KNX, etc.), and optional UI. The installer generates a self-contained folder you can share with teammates.

The installer lives in the public spx-examples repository: https://github.com/HammerHeads-Engineers/spx-examples

Golden path (6 steps)

Prerequisites:

• macOS, Linux, or Windows (PowerShell or pwsh)

• Docker and Docker Compose v2 (docker compose)

• Python 3.9+

1. Clone spx-examples:

   git clone https://github.com/HammerHeads-Engineers/spx-examples.git
   cd spx-examples

2. Set SPX_PRODUCT_KEY (treat it as a secret; use env/CI secrets and never commit it):

   export SPX_PRODUCT_KEY="YOUR_REAL_KEY"

   $env:SPX_PRODUCT_KEY = "YOUR_REAL_KEY"

3. Generate a bundle (canonical command):

   python -m installer generate \
     --packages smart_building_pack \
     --profile-ids bms_quickstart \
     --with-ui \
     --output build/spx-generated

4. Enter the output folder:

   cd build/spx-generated

5. Start the stack (script or docker compose):

   • macOS/Linux: ./spx-start.sh

   • Windows: pwsh ./spx-start.ps1

   • Or: docker compose -f docker-compose.generated.yml --env-file .env up -d

6. Verify it is healthy:

   docker compose -f docker-compose.generated.yml --env-file .env ps
   curl -fsS http://localhost:8000/health

   Success criteria:

   • curl returns JSON with "status":"ok".

   • docker compose ps shows spx-server as Up (healthy).

Prerequisites

• Docker and Docker Compose v2 (docker compose)

• Python 3.9+ with pip (installer requirement in spx-examples pyproject.toml)

• Tests and local tooling in spx-examples are exercised on Python 3.9-3.12 in CI (pack tests run on Python 3.10.14)

• A valid SPX product key (SPX_PRODUCT_KEY)

Optional:

• Node.js + npm if you include BLE models (the start script installs @simplephysx/spx-ble-adapter).

Run the installer from the repo (interactive wizard)

git clone https://github.com/HammerHeads-Engineers/spx-examples.git
cd spx-examples

Start the wizard:

• macOS/Linux: ./spx-install.sh

• Windows (PowerShell): pwsh ./spx-install.ps1

By default, artifacts are generated under build/spx-generated/.

Non-interactive generation

Use pack and profile selectors to build bundles without prompts. Example:

python -m installer generate \
  --packages embedded_lab_pack \
  --profile-ids scpi_lab \
  --no-ui \
  --start \
  --output build/spx-generated

Other useful flags:

• --protocols mqtt,modbus,http (filter by protocols)

• --no-examples (skip model/instance bootstrap in start scripts)

• --no-ui or --with-ui

• --allow-missing-product-key (writes REPLACE_ME into .env)

• --start (launch after generating)

What gets generated

Inside the output folder (for example build/spx-generated/):

• docker-compose.generated.yml: compose file with only the selected services.

• .env: product key placeholder (SPX_PRODUCT_KEY=REPLACE_ME) for this bundle.

• bundle.json: selected packages, models, services, and instances; consumed by the bootstrap runner to register models and create instances.

• bootstrap_runner.py: lightweight bootstrap script invoked by spx-start.

• spx-start.sh / spx-stop.sh: start/stop helpers for Bash or zsh.

• spx-start.ps1 / spx-stop.ps1: start/stop helpers for PowerShell.

• assets/: copied service configs (MQTT, KNX, Home Assistant, Matter).

• extensions/: copied custom Python extensions.

• library/: selected model YAMLs copied into the bundle for self-contained sharing.

Start and stop the stack

From the generated folder:

• Start:

  • macOS/Linux: ./spx-start.sh

  • Windows: pwsh ./spx-start.ps1

• Stop:

  • macOS/Linux: ./spx-stop.sh

  • Windows: pwsh ./spx-stop.ps1

The start scripts:

• verify docker and Python,

• install missing Python modules (requests, spx-python),

• optionally install and run the BLE adapter if BLE services are selected,

• run docker compose down --remove-orphans and then docker compose up -d,

• bootstrap models and instances from bundle.json.

Security and CI notes

• Do not commit .env files containing SPX_PRODUCT_KEY.

• Use CI secrets to inject SPX_PRODUCT_KEY and SPX_BASE_URL.

• Share bundles with SPX_PRODUCT_KEY=REPLACE_ME (or remove .env before sharing).

• Avoid putting keys into command history; prefer environment variables.

How to verify (Integrator / QA / Developer)

Integrator:

• curl -fsS http://localhost:8000/health

• docker compose -f docker-compose.generated.yml --env-file .env ps

• Confirm your target protocol port is listening (for example Modbus on 5020-5120).

QA/CI:

• python -m installer generate --packages <pack> --output build/ci/<pack> --no-start

• build/ci/<pack>/spx-start.sh

• curl -fsS http://localhost:8000/health

Developer:

• Update library/catalog/*.yaml and profiles/<pack>/*.yaml, then regenerate: python -m installer generate --packages <pack> --output build/spx-generated

Cleanup and uninstall

• Stop containers: ./spx-stop.sh or pwsh ./spx-stop.ps1

• Remove containers and volumes: docker compose -f docker-compose.generated.yml --env-file .env down -v

• Remove generated files: delete the generated folder (for example build/spx-generated)

• Remove BLE adapter (if installed): npm uninstall -g @simplephysx/spx-ble-adapter

Build shareable installer packages (optional)

If you need a redistributable archive (no repo clone):

scripts/build_installer_package.sh

This creates dist/spx-installer/ and dist/spx-installer.tgz. Recipients extract and run ./spx-install.sh or pwsh ./spx-install.ps1.

For single-file installers:

scripts/build_self_extractors.sh --version v1.2.3

Outputs:

• dist/spx-installer-v1.2.3.run (macOS/Linux)

• dist/spx-installer-v1.2.3.ps1 (Windows)

Packs and profiles

Packs and profiles define the model and service bundles available to the installer. See: Industry packs and profiles.
