Eastron / Microcare SDM Meters

Integration with Eastron/Microcare SDM630 and SDM120 electricity meters via Modbus protocol.

Overview

This bundle provides integration with Eastron and Microcare energy meters, supporting both three-phase (SDM630, SDM72D-M-2) and single-phase (SDM120) installations. The components communicate with meters through the Modbus TCP protocol, enabling real-time energy monitoring and comprehensive data collection in OpenEMS.

Eastron meters are widely deployed in residential, commercial, and industrial installations. They support energy consumption, production, or grid measurement depending on configuration.
