OpenEMS
OpenEMS is a free, modular open-source platform for monitoring, controlling, and integrating energy storage, renewable sources, and related devices and services. Its stack combines OpenEMS Edge for on-site device communication and control, OpenEMS UI for browser and smartphone access, and OpenEMS Backend for connecting Edge systems over the internet for aggregation, monitoring, and control. The architecture supports fast PLC-like control and reusable device-independent algorithms. Integrations cover batteries, solar and battery inverters, EV chargers, meters, tariffs, and data services, using interfaces such as MQTT, Modbus/TCP, Modbus/RTU, InfluxDB, M-Bus, 1-Wire, JSON/REST, and JSON/Websocket. Edge and Backend use Eclipse Public License 2.0; UI uses GNU Affero General Public License 3. Production deployment guidance covers Debian, Ubuntu, or Docker, and Java 21 is required. Source is available online and on GitHub, with monthly releases described. The getting-started setup is intended for testing, not production.
