DLMS Meter Simulator

DLMS Meter Simulator is a high-performance platform for testing DLMS/COSEM-compatible systems at scale. It emulates anything from a single device to millions of meters, delivering realistic energy readings, voltage and current measurements, and load profiles, with DLMS Security Suite support and modern cryptography.

Built for demanding lab, development, and QA environments, it reproduces real-world network behavior — configurable latency, jitter, and unreliable connectivity — alongside power-outage scenarios, while enabling heavy load and stress testing for Head-End and MDM systems.

With flexible deployment options and straightforward integration, it lets teams validate performance, security, and interoperability quickly and reliably.

• Massive-scale simulation - Emulate anything from a single meter to millions, with many meters served per network endpoint — far beyond the scale typical simulators reach.
• DLMS Security Suite support - Security Suites 0, 1, and 2, with modern AES cryptography, high-level authentication (GMAC, SHA-256), and optional data compression.
• Realistic meter behavior - Believable, reproducible register values and load profiles — interval, half-hour, and daily — matching real-world patterns.
• Load profiles & outage scenarios - Configurable load-profile channels and intervals, plus power-down/outage simulation with standards-aligned status flags.
• Network-condition emulation - Inject latency and jitter and simulate unreliable links to validate client behavior under stress.
• Head-End & MDM load testing - Generate high-load, high-stress traffic to validate large-scale system performance.
• Built-in management UI - Configure and monitor the simulator through a multi-language web interface.
• Live reconfiguration - Update the simulated fleet on the fly without restarting.
• Flexible deployment - Run via Docker, Kubernetes (Helm chart), or as a portable hardware appliance for field demos and labs.
• Standards-based integration - Standard DLMS/COSEM interfaces connect to any Head-End or MDM system.

Thanks to modern technologies, the DLMS Meter Simulator delivers high-performance simulation. It enables seamless testing and validation of various software platforms — from small setups to large deployments — while maintaining accuracy, security, and real-world-like behavior. Deterministic data generation makes test runs repeatable, ensuring issues are reproducible across teams and CI pipelines.
