- Parse OWM One Call 3.0 weather alerts and map to Warning structs
- Map hourly UVI from OWM response to HourlyForecast.UVIndex
- Add severity helper mapping OWM alert tags to severity levels
- Extract UVIndex through compute layer to timeline slots
- Smart warnings: use provider-supplied alerts, fall back to DWD
- Show UV index in dashboard timeline tooltips
- Add provider description below forecast dropdown with i18n
Include favicon.svg in go:embed directive to fix 404 in production.
Add legal notice (impress) and privacy policy pages with full EN/DE
translations, route handlers, and footer links.
Add OpenWeatherMap One Call API 3.0 as alternative weather provider with
configurable selection in the Forecast tab. Includes server-side retry
transport with exponential backoff for all weather providers, structured
error responses with type classification, auto-fetch on stale dashboard
data, and improved error UX with specific messages.
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.
Move dynamic HTML generation from JS template literals to native
<template> elements rendered server-side with i18n. JS now clones
templates, fills data-slot attributes via textContent (auto-escaped),
and uses event delegation instead of inline onclick/window globals.
Insert step 5 (Configure AI) into the getting-started guide with
mentions of Setup > AI Summary, --llm-provider/--llm-model CLI flags,
and Ollama local support. Renumber Fetch Forecast to step 6 and View
Dashboard to step 7.
Remove unused crypto module, DataDir/DefaultDBPath (SQLite remnant),
and ListenAndServe (replaced by direct http.Server in main). Strip 17
unreferenced i18n keys from en/de translations. Add --llm-provider,
--llm-model, and --llm-endpoint CLI flags for runtime LLM override
without a config file. Rewrite README with correct Go 1.25 version,
shields, LLM providers table, Docker/Helm deployment docs. Fix
.gitignore pattern to not match cmd/heatguard/ directory.
Pass profile timezone through DashboardData so the frontend can
compute the current hour and highlight it on the heatmap (white ring +
orange triangle marker). Only activates when the dashboard date matches
today in the profile timezone.
In cold weather (peak < 22°C, risk low), the risk card now shows a
teal "Comfortable" presentation with a checkmark icon instead of the
generic green "Low" shield.
- 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 Unicode edit/delete characters with SVG pencil/trash icon buttons,
add edit mode visual feedback (orange ring + Save/Cancel buttons), group
action buttons consistently across all entity types, add hover effects to
list items, and constrain all pages to 1800px max-width via layout template.
Skip LLM actions call when peakTempC < 22°C and risk is low. Add
low-risk guidance to both summary and actions system prompts so the
LLM returns appropriate responses on mild days. Restructure dashboard
into a top-level two-column grid with sidebar beside all main content
and remove max-w-7xl cap for full-width layout.
Replace the 720x200 SVG line chart and separate cooling strip with a
compact two-row heatmap: 24 colored temp cells (48px tall) with a thin
cooling mode row below. Hour labels every 3h, tooltip on hover/click,
responsive mobile layout (temp values hidden <640px, color-only).
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
