The challenge
Solar, battery and inverter data in Home Assistant is detailed but raw. A family wants plain answers: where the power is coming from, how long the battery will last, what tomorrow and load shedding look like, and what it all saved.
How it works
A Node.js engine reads Home Assistant, builds a clean live model and an analysis layer, and serves a black-and-gold phone app. Control features are designed but deliberately locked until the observer has proven itself.
What we built
- Live energy flow between solar, grid, house and battery, updated every 2 seconds
- Solar-today chart and an opportunity tip for spare power
- Tonight and tomorrow forecast, with load-shedding warnings and battery pre-charge planning
- Daily briefing that logs every event with its reason, never just "AI decided"
- History in rand: money saved, solar produced, self-sufficiency
- Home hub for lights, cameras, TV, geyser, pool pump, water tank and holiday mode
- Read-only by design: it never changes inverter settings
Where it stands
Working prototype with a full demo mode, built to run live on a home system.
