How Helios evolves, straight from the project's GitHub milestones.
Loading the roadmap...
Helios Forecast is a separate integration, planned and released at its own pace. These milestones come straight from its own GitHub repository, independent from the card above.

I'm Jérôme, 44, the developer behind Helios. After years spent across the whole stack, backend, frontend, 3D, games, embedded, I wanted to build something that truly matters to me.
A card won't save the planet, I know. But guilt and numbers nobody reads change no one: we change when we can finally see what's happening in our own home. That's the whole point of Helios: make energy visible, tangible, even beautiful, so that acting stops being a chore and becomes the obvious thing to do.
Helios is free and open source, built by a single person, in full transparency.
Helios is an independent community project. It is not created or endorsed by, nor affiliated with, the Open Home Foundation or Home Assistant. Home Assistant and the Home Assistant logo are trademarks of the Open Home Foundation.
