Generated from engineering intent
The building system is created from model definitions and requirements, not assembled manually as a static demo scene.
Before hardware exists
AI-assisted Digital Twin Platform
SPX creates, runs, validates, and improves real-world system models in one runtime.

Why SPX exists
Build and validate system behavior before hardware is ready.
SPX gives engineering teams a live digital twin runtime for earlier integration, protocol testing, and validation.
Running as a live system
SPX instantiates the twin immediately so you can inspect state, behavior, and interactions before any physical setup exists.
Connected through real protocols
Communication endpoints are part of the twin itself, so software can talk to MQTT, BACnet, Modbus, OPC UA, or KNX behavior in one runtime.
Runtime proof
Inspect a running digital twin, not a static mock.
SPX exposes live instances, values, scenarios, communication endpoints, and debugging evidence while the twin is running.
Runtime dashboard with active digital twins, live values, and observability.
Live twin instances
Inspect endpoints, values, state, and health for each running digital twin in one place.
Runtime scenarios and snapshots
Recreate timing-sensitive flows and restart from known baselines without rebuilding your whole test environment.
Observability while behavior is live
Diagnose faults, drift, and communication behavior from runtime evidence instead of inferring from incomplete stubs.
Protocols
Protocol simulators connected to running digital twins.
Validate MQTT, Modbus TCP, OPC UA, BACnet, and KNX integrations against controllable twin behavior before physical systems are ready.
Validate MQTT device behavior, topic flows, and automation scenarios without physical hardware.
Test OPC UA clients against realistic nodes, subscriptions, namespaces, and twin behavior.
Test Modbus TCP devices with realistic register maps, timeouts, and runtime logic.
Validate BACnet objects, schedules, alarms, and smart-building workflows.
Validate KNX group-address traffic, actuator semantics, and building automations.
