Solar Cube is a Home Energy Management System (HEMS) that automatically optimizes energy from PV, the grid, and battery storage based on tariffs, forecasts, and real-time system conditions. It runs locally within your network, offering monitoring via Home Assistant and access to historical data through a web portal. The PRO plan also enables secure remote access via a mobile app.
