 If you run Music Assistant as a Home Assistant add-on:
 - Use the IP address of your Home Assistant server
- Enter `8095` in the port field
 - Do **not** use your Home Assistant URL or ingress URL

 ### Remote Access

-For access outside your home network, you'll need to expose Music Assistant through a reverse proxy (e.g., Nginx Proxy Manager, Cloudflare Tunnel).

-## Authentication
-
-Ensemble supports multiple authentication methods:
-
-| Method | Status |
-|--------|--------|
-| Music Assistant native auth | Tested |
-| No authentication | Tested |
-| Authelia | Implemented, not recently tested |
-| HTTP Basic Auth | Implemented, not recently tested |

ChrisandClaude Opus 4.5	1f3a01c22f	Bump version to 2.9.3-beta Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-01-27 19:20:19 +00:00
ChrisandClaude Opus 4.5	27e1b8b746	Fix local player track data disappearing when selected When selecting the builtin/local player from the player selector overlay, the track info would disappear because the queue API returns null for local players. The code was clearing _currentTrack unconditionally. Now for the builtin player: - Preserve cached track data instead of clearing it - Restore from cache if _currentTrack is null - Update notification with actual track info when available Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-01-27 19:14:36 +00:00
ChrisandClaude Opus 4.5	9be3737a9d	Add centralized LibraryStatusService for consistent library/favorite state - Create LibraryStatusService singleton for single source of truth - Add LibraryStatusMixin for reactive status in StatefulWidgets - Convert all card widgets to use centralized service: - album_card, artist_card, playlist_card, podcast_card - radio_station_card, track_row, audiobook_row - Convert detail screens: album_details_screen, artist_details_screen - Fix album stuck in library after removal: - Add removeFromCacheByLibraryId() to SyncService - Add markCachedItemDeletedByLibraryId() to DatabaseService - Update removeFromLibrary() to sync all caches This ensures library/favorite status changes are immediately reflected across all instances of the same item throughout the app. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-01-27 19:14:36 +00:00
ChrisandClaude Opus 4.5	882e8b2ea4	Simplify player selection logic Remove confusing auto-switch behavior that could change the selected player unexpectedly right before the user taps play. Removed settings: - "Prefer Local Player" - "Disable Auto-Switch" New simplified logic: 1. User's manual selection is always respected 2. On app reopen: restore last selected player 3. If selected player goes offline: switch to local player 4. First launch (no history): select local player 5. Local player unavailable: select first available Kept "Smart Sort" setting for display order only. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-01-27 19:14:36 +00:00
ChrisandClaude Opus 4.5	aef9423b42	Improve adaptive color contrast using HCT color space - Replace HSL-based color adjustments with HCT (Material Design 3 standard) - Use proper WCAG contrast ratio calculations instead of luminance threshold - Implement binary search to find minimum tone adjustment for contrast - Ensure minimum chroma of 36 for primary colors to prevent washed-out highlights - Add color scheme caching for instant loading on revisits - Pre-extract colors on album tap for faster initial load Fixes issue where highlighted library button was darker than unhighlighted state on albums with dark/muted covers (e.g., Portishead, NIHT).
