- Hourly data exporter (InfluxDB → CSV) for prices, P1, irradiance. - LP-based 24h-foresight oracle dispatch with SoC-consistent state engine. - Reverse-engineered thuisbatterijgids.nl formula (matches their quotes to within €0.50 across three battery configs). - Catalog scraper for the 52 batteries on thuisbatterijgids.net via their /wp-json REST endpoint. - Web app (Flask) that ranks every catalog battery by honest payback and contrasts with the store's quote, deployable via the included Procfile.
