Developers

Developer resources and runnable SPX models

Use the SPX developer hub as the technical layer behind the product: runnable models, industry packs, protocol examples, tests, and agent-ready workflows on GitHub.

Getting started

Install SPX, check requirements, connect MCP, and run the first example before moving into full docs.

Install SPX

Getting Started

A quick onboarding page for installing SPX, checking requirements, connecting MCP, and running the first example.

Repository

Start from the public SPX examples repository on the current develop branch.

develop branch

SPX Examples on GitHub

Runnable examples, tests, profiles, and implementation patterns for SPX SDK and server workflows.

Model library

Inspect the catalog and code-defined model language behind reusable digital twins.

90+ cataloged models

Model Catalog

Cataloged SPX models across building, industrial, energy, lab, and environment domains.

code-defined twins

Model Language

The YAML modeling language used to define attributes, actions, communication, scenarios, and hooks.

Industry packs

Explore grouped examples for building automation, industrial IIoT, energy, embedded, and lab workflows.

BMS examples

Smart Building Pack

Smart-building examples for HVAC, lighting, safety, telemetry, BACnet, KNX, MQTT, Modbus, OPC UA, and Matter.

factory examples

Industrial IIoT Pack

Industrial examples for process cells, workcells, controllers, gateways, Modbus, OPC UA, MQTT, HTTP, and SCPI.

e-mobility examples

Energy Pack

Energy and EV infrastructure examples including OCPP, Modbus EVSEs, CSMS twins, and power-meter telemetry.

CI and lab examples

Embedded & Lab Pack

Embedded, firmware-validation, SCPI, BLE, LwM2M, MQTT, and lab-instrument examples for test environments.

Agent workflows

Use local MCP workflows to inspect models, validate definitions, and control running SPX instances.

MCP-ready workflows

MCP Workflow

Local MCP guidance for agent-assisted model inspection, validation, runtime control, and repository work.

Protocol examples

Open representative protocol model definitions for Modbus, OPC UA, BACnet, KNX, and MQTT.

Modbus

Modbus example model

A Modbus master PLC-style model that supervises device behavior through direct Modbus TCP endpoints.

OPC UA

OPC UA example model

A process-cell OPC UA model for testing nodes, values, subscriptions, and industrial client behavior.

BACnet

BACnet example model

A smart-building HVAC model that exposes BACnet behavior for BMS and commissioning-style validation.

KNX

KNX example model

A room-controller KNX model for testing group-address behavior and building automation logic.

MQTT

MQTT example model

An MQTT environment sensor model for testing telemetry topics, device-like state, and integration flows.
