The plan for Helios, straight from the project's GitHub milestones: what shipped, what's brewing right now, and what's on the horizon.

Helios Forecast is a separate integration, planned and released on its own cadence. These milestones come straight from its own GitHub repository, independent from the card above.

I'm Jérôme, 44, the developer behind Helios. After years across the whole stack, backend, frontend, 3D, games, embedded, I wanted to build something that actually matters to me.
A card won't save the planet, I know. But guilt and numbers nobody reads change no one: people change when they can finally see what's happening in their own home. That's the whole point of Helios, make energy visible, tangible, even beautiful, so acting on it stops feeling like a duty and starts feeling obvious.
Helios is free and open source, built by one person in the open.
Helios is an independent community project, not created by, endorsed by, or affiliated with the Open Home Foundation or Home Assistant. Home Assistant and the Home Assistant logo are trademarks of the Open Home Foundation.
