= Hager ECR380D Meter

Three-phase electricity meter for energy measurement via Modbus protocol.

== Overview

This bundle provides integration with the Hager ECR380D three-phase electricity meter, designed for precise energy measurement in commercial and industrial installations. The component communicates with the meter through the Modbus TCP protocol, enabling real-time energy monitoring, power measurement, and comprehensive data collection in OpenEMS.

The Hager ECR380D supports measurement of grid consumption, production, or consumption energy depending on configuration. It provides detailed per-phase and cumulative measurements for complete energy monitoring.
