Helio is an open-source application that provides real-time data on daily energy production from rooftop solar systems, directly sourced from the inverter's energy counter. It offers historical data, savings calculations, and can be deployed on Vercel in five minutes, with no tracking or database requirements.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
