Hey Product Hunt 👋
Our rooftop solar came with the SmartClient app. Every day I opened it for one number: how many units did the roof make today? It took 6 taps to find it.
So I built Helio. It opens straight on today's units, read from the inverter's own counter, with live power, history and savings in your own currency around it.

Which inverter brand do you use? That decides what I support next.
Love the idea! Turning a 6-tap daily routine into a simple, focused dashboard is exactly the kind of problem-solving indie products should be about. Also love the self-hosted, privacy-first approach.
Today's units plus a tariff you can set yourself is a useful combination. It makes the savings estimate easier to relate to your own bill.

Who hunted Helio?
Helio was hunted by Rishi Shah. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it.
