2026.7.2

Helios Forecast 2026.7.2. Update via HACS.

Fixed

• Setup no longer crashes when Open-Meteo returns a missing cloud hour (a None value), which failed the coordinator in a loop (setup_retry) whenever a production sensor was configured. Thanks @chaoslion and @MrShwa for the report and the confirmation. (#14)

Improved

• The reliability score degrades gently across the forecast horizon instead of dropping ~12 %/day and bottoming out by day +5, so the later days are no longer under-rated. (#16)
• The learned correction now accounts for outdoor temperature: panels lose output as they heat up, and the analog ensemble matches past hours on temperature as well as cloud cover and sun geometry. (#17)

Internal

• Full strict cleanup pass: ruff lint and formatting, a fully type-checked package (mypy), and a CI lint job so it stays clean. No behaviour change.

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.
