v2.9.0-rc2 — features + bug fixes (beta)

⚠️ Pre-release for HACS beta testers — not auto-installed for normal users.

Install: HACS → Air Quality Card → ⋮ → "Redownload" → enable "Show beta versions" → pick v2.9.0-rc2.

What's new since rc1

Bug fixes (carried over from rc1)

• #22 — Time-based graph X axis (spikes appear at the correct time)
• CO2 status now correctly shows all 5 tiers including "Moderate"
• Humidity/temperature boundary off-by-one fixes

Features (new in rc2)

• #25 — Outdoor-only mode (already in rc1)
• #23 — Optional min/max per metric (show_min_max: true)
• #21 + #24 — Custom thresholds per metric (e.g., temperature_thresholds: [22, 25, 28, 31])
• #20 — Compact display mode (display: compact) with HA-native tap_action/hold_action/double_tap_action
• #19 — Custom sensor order (order: [temperature, humidity, co2, ...])
• #10 — Localization for status badge, recommendations, radon advisory titles, and editor labels (en/es/fr/de). Spanish/French/German contributed by @b0rv3g4r4 from PR #11.

Smoke-test checklist

Regressions from rc1 (highest priority)

• All sensors that worked in rc1 still render normally
• CO2 still shows "Moderate" for 800-1000 ppm range
• tVOC spikes still align with their actual time on the graph
• Outdoor-only configs still hide the recommendation strip
• Existing dashboards (no new config) look identical to rc1

New features

• Min/max — add show_min_max: true → confirm ↓ X · ↑ Y line under each metric
• Custom thresholds — try temperature_thresholds: [22, 25, 28, 31] on a tropical-climate temp sensor → 28°C should now show "Warm" (orange), not "Hot" (red)
• Compact mode — display: compact + tap_action: { action: navigate, navigation_path: /your/path } → card shrinks to title + badge and navigates on tap
• Reorder — order: [temperature, humidity, co2, pm10, pm25] → sensors appear in that order
• Localization — set HA language to Spanish (or override with language: es) → status badge shows "Excelente"/"Bueno", recommendations show "Abre la ventana" etc.

Editor (visual config)

• Open the editor on an existing card. Confirm all sections render, labels show correctly, save and reload round-trips cleanly.
• In Advanced, confirm the new options appear: show_min_max, order, display, tap_action, hold_action, double_tap_action, language.

Console check

Browser DevTools should show: AIR-QUALITY-CARD v2.9.0-rc2. No new errors compared to rc1.

Known limitations in rc2 (deferred to rc3 or stable)

• Per-sensor status labels (Safe / Low / Moderate / High / Dangerous on each metric) are not yet translated — they still show English. The status badge at the top is translated. Will land in a follow-up.
• Radon advisory subtitle prose ("EPA recommends mitigation above X") is still English; the title is translated.
• Editor doesn't have a UI picker for <metric>_thresholds — set via YAML.

Tests

node test.js — 360 passed, 0 failed (up from 250 in rc1).
