Add bettervent.me provider with lazy-cached device list (~6,700 Eurovent-certified
heat pumps), search API endpoint, device search UI with auto-populate, BTU/kW unit
switcher for European users, and extended AC fields (SEER, SCOP, COP, TOL, Tbiv,
refrigerant). Closes#2.
Model heating mode when rooms have net heat loss in cold weather (<10°C).
AC units with heat pump capability (canHeat) provide heating capacity,
with the same 20% headroom threshold used for cooling. Adds cold risk
detection, cold-weather actions, and full frontend support including
heating mode timeline colors, room budget heating display, and i18n.
- Fix ComputeRoomBudget: no-AC rooms check if open-window ventilation
can offset gains instead of defaulting to Overloaded. Net-cooling
rooms are now Comfortable; ventilation-solvable rooms are Marginal.
- Add "comfort" cool mode for hours where outdoor is >5°C below indoor
and budget is not overloaded (winter/cold scenarios).
- Reorder determineCoolMode: sealed now before overloaded, fixing
humid+cold+no-AC giving "overloaded" instead of "sealed".
- Update LLM prompts: document comfort coolMode, add cold-weather
guidance for summary and actions generation.
- Add dashboard forecast refresh button: fetches fresh forecast +
warnings, then re-runs compute and LLM pipelines.
- Extract forecast fetch into shared fetchForecastForProfile() in db.js,
deduplicating logic between setup.js and dashboard.js.
- Add indoor humidity support, pressure display, and cool mode sealed
integration test.
Replace CLI + SQLite architecture with a Go web server + vanilla JS
frontend using IndexedDB for all client-side data storage.
- Remove: cli, store, report, static packages
- Add: compute engine (BuildDashboard), server package, web UI
- Add: setup page with CRUD for profiles, rooms, devices, occupants, AC
- Add: dashboard with SVG temperature timeline, risk analysis, care checklist
- Add: i18n support (English/German) with server-side Go templates
- Add: LLM provider selection UI with client-side API key storage
- Add: per-room indoor temperature, edit buttons, language-aware AI summary
