OpenEMS is an open-source, modular Energy Management System for monitoring and controlling energy storage, photovoltaics, EV chargers, heat pumps, and related devices. It consists of an on-site Edge runtime, a web/mobile UI, and a cloud Backend for aggregation and remote control.
Use cases
- manage home solar battery storage and PV self-consumption
- control EV charging based on solar surplus
- optimize energy use with time-of-use electricity tariffs
- integrate heat pumps and electrolysers into energy management
- monitor and control multiple sites from a central backend
- build PLC-like fast control algorithms for energy devices
When to choose
- you need an open, modular platform to integrate heterogeneous energy hardware
- you want local edge control plus central cloud aggregation
- you need device-independent, reusable control algorithms
When to avoid
- you need a turnkey consumer app without setup effort
- your project is outside energy/IoT domains
- you cannot work with Java/OSGi-based systems
