2026.7.1
First HACS release of Helios Forecast.
An accurate, self-learning solar production forecast for Home Assistant. It computes your PV forecast on the server from Open-Meteo irradiance and your installation geometry, then learns a correction from your home's own recorded production so it tracks your real behaviour over time.
What you get:
- A native solar forecast provider for the official Energy dashboard.
- A clean set of sensors (power now and next hour, per-day energy and peaks over 7 days, energy left today) ready for automations.
- A sub-hourly detail series the Helios card reads for full-fidelity visuals.
Configuration is one entry per panel line, so each roof orientation gets its own forecast, device and entities.
