Protocol simulator
Use SPX to simulate KNX group-address traffic, actuator behavior, schedules, and runtime control in one digital twin environment.
SPX works as a KNX simulator for group-address traffic, sensors, actuators, schedules, and smart-building automation logic. The simulator is tied to a running digital twin, so KNX behavior can be validated before onsite commissioning.
SPX gives building automation teams a repeatable way to test KNX integrations, actuator semantics, and scenario-driven behavior without waiting for physical KNX hardware or a complete building setup.
Related features
Expose protocol connections as part of the running twin so software can validate live communication behavior.
Recreate real-world scenarios, edge cases, timing issues, and failure modes before those problems reach hardware-dependent stages.
Start from reusable device, system, and domain models instead of rebuilding every twin from scratch.
