Helio Solar

Helio Solar is a dashboard for rooftop solar. It reads the inverter's own counter for systems that report to ShineMonitor through an Eybond WiFi stick, so the units shown match the meter. The site includes a live demo you can open in the browser, daily curves, health checks adjusted for weather, CSV export, and an optional evening Telegram message. It says there is no Helio account and no database holding your readings; you deploy your own copy. The FAQ says it is free, MIT licensed, and runs on Vercel's free plan. No paid Helio tier was shown, so the pricing model is Free. The demo and the dashboard are web software. Sources are helio.rishishah.in, including the FAQ.
