HelioPeak 2.3.2 — Send your solar data to an AI assistant
NEW: Export for AI Analysis
Generate a self-contained file with your full production, consumption, and grid data, plus a structured prompt designed for AI assistants. Paste it into Claude, ChatGPT, Gemini, or any other AI of your choice and get a detailed 14-section analysis. No subscription, no server in the loop, your data stays with you.
- Choose between Large (24 months of data) or Small (3 months) depending on which AI you'll use
- Pick the response language: English, Dutch, French, German, Italian, or Spanish
- Multi-system export — select which systems to include
- One-tap share to Mail or Messages bundles the prompt and the file together, ready to forward to your AI assistant
- Available free for all users from Settings → Export & Reports
NEW: Grid cards on every tab
Grid Import and Grid Export cards now appear on all three Dashboard tabs (Production, Consumption, Combined) and on the matching Day charts. Cards automatically hide for systems without grid data.
Reliability
- Fixed a freeze that could briefly affect cold launches on older devices with multi-year histories
- Resolved an edge case in the cached data export where a small amount of legacy data could cause a partial export
- Help & FAQ deep-links from Settings now navigate correctly on the first tap
Privacy & Security
- API key entry now uses a masked field with a reveal toggle, matching iOS best practices for credentials
- Tightened error handling to ensure no PVOutput response details ever appear in user-visible error messages
Thank you for using HelioPeak. As always, feedback is welcome at info@heliopeak.app.
