Add 4 new audio visualization modes powered by MusicAnalyzer:
- pulse_on_beat: BPM-synced pulsing with smooth beat phase
- energy_gradient: bass/mid/treble mapped to scrolling gradient
- spectrum_bands: three VU zones for frequency bands
- strobe_on_drop: state-driven strobe on detected musical drops
MusicAnalyzer provides BPM estimation (median IBI), beat phase tracking,
asymmetric energy envelope, 3-band frequency splitting, and drop
detection state machine (idle/buildup/drop/recovery).
Add auto_gain audio filter for automatic level normalization via rolling
peak tracking with configurable target level and response time.
Deprecate auto_gain on Audio Value Source (use the filter instead).
Mathematical wave generator that produces per-LED colors from
configurable waveform layers (sine, triangle, sawtooth, square) with
superposition, mapped through a gradient palette. Supports sync clocks,
bindable speed, and up to 8 wave layers.
- Storage model with wave validation and apply_update
- Numpy-vectorized stream with gradient LUT color mapping
- API schemas (create/update/response) and route registration
- Frontend editor with dynamic wave layer rows, gradient picker,
speed widget, and IconSelect waveform selectors
- i18n in en/ru/zh
Move HA sources, weather sources, game integration, and MQTT settings
into a dedicated Integrations top-level tab with tab-registry pattern.
Collapse tab labels to icon-only at narrow desktop widths (<=1100px)
to prevent toolbar overflow.
Rewrite audio source editor modal for capture/processed types only.
Remove old multichannel/mono/band_extract HTML sections and i18n keys.
Clean up legacy DOM section null-checks in audio-sources.ts.
Add Audio Processing Templates management UI to Streams tab:
- Template editor modal with filter list via FilterListManager
- CardSection with reconciliation for template cards
- DataCache instances for templates and audio filter defs
- Audio filter icon mappings in filter-list.ts
- i18n keys in en/ru/zh locales
MQTT broker connections are now managed as entities (like HA sources)
instead of a single global config. Each MQTTSource gets its own
runtime with auto-reconnect, ref-counted via MQTTManager.
Backend:
- MQTTSource dataclass + MQTTSourceStore (SQLite)
- MQTTRuntime (per-broker connection, refactored from MQTTService)
- MQTTManager (ref-counted pool, same pattern as HAManager)
- CRUD API at /api/v1/mqtt/sources + test + status endpoints
- MQTTRule gains mqtt_source_id field for source selection
- Automation engine acquires/releases MQTT runtimes automatically
- Legacy MQTTService kept for backward compat during transition
Frontend:
- MQTT source cards in Streams > Integrations tab
- Create/edit modal with test button
- Dashboard integration cards with health-dot indicators
- Removed MQTT tab from settings modal
Receive real-time events from games (CS2, Dota 2, LoL, etc.) and drive
LED effects through the existing color strip and value source pipelines.
Core:
- GameEventBus (thread-safe pub/sub) with standardized 23-type event vocabulary
- GameAdapter ABC + AdapterRegistry + MappingAdapter (YAML-driven)
- Built-in adapters: CS2 GSI, Dota 2 GSI, LoL Live Client, Generic Webhook
- Community YAML adapters: Minecraft, Valorant, Rocket League
- GameEventColorStripStream with 5 effects (flash/pulse/sweep/color_shift/breathing)
- GameEventValueSource with EMA smoothing and timeout
- 4 built-in effect presets (FPS Combat, MOBA Health, Racing, Generic Alert)
- Auto-setup for Valve GSI games (Steam path detection, cfg file writing)
- Demo capture engine exposed to non-demo mode
Frontend:
- Game tab in Streams tree navigation with integration cards

API:
- Full CRUD for game integrations
- Event ingestion endpoint (adapter-level auth)
- Adapter metadata, presets, auto-setup, status/diagnostics endpoints
New value source that monitors host hardware via psutil/pynvml:
cpu_load, cpu_temp, gpu_load, gpu_temp, ram_usage, disk_usage,
network_rx, network_tx, battery_level, fan_speed.
Each metric normalizes to 0.0-1.0 with configurable ranges, poll
interval, EMA smoothing, and sensor_label for multi-sensor systems.
Conditional editor fields show/hide based on selected metric.
Also fixes: WS test crash when raw_value streams lack _min_ha attr,
toast timer overlap on rapid calls, SW cache bump to v34.
Add third theme mode (system) that follows OS prefers-color-scheme.
Theme button cycles dark → light → system with monitor icon.
Listens for OS preference changes in real time when in system mode.
Fix showToast clearing previous timer so rapid calls don't cause
the toast to disappear early.
WS now sends color RGB data for color-type streams. Test modal renders
a color history swatch strip below the chart, colors the chart line and
fill area with the current output color, and shows rgb() in the stats.
Works for static_color, animated_color, and adaptive_time_color sources.
New value source types:
- ha_entity: reads numeric values from HA entity state/attribute, normalizes
via min/max range, applies EMA smoothing. EntitySelect for HA connection
and entity selection with live entity list fetching.
- gradient_map: maps a float value source (0-1) through a gradient entity.
EntitySelect for both input source and gradient with inline previews.
- css_extract: extracts single color by averaging LED range from a color
strip source. EntitySelect for source selection.
Value source type picker:
- Filter tabs (All / Numeric / Color) above the icon grid
- showTypePicker extended with filterTabs + onFilterChange support
Palette selectors converted to EntitySelect:
- Effect palette, gradient preset, and audio palette selectors now use
command-palette style EntitySelect with gradient strip previews
Tab indicator fixes:
- Icon now updates on tab switch (was passing no args to updateTabIndicator)
- Visible with any background effect active, not just Noise Field
- Noise Field is the default background effect for new users
Dashboard section collapse fix:
- Split header into clickable toggle (chevron+label) and non-clickable
actions area — buttons no longer trigger collapse/expand
Discriminated union fix (422 errors):
- source_type/target_type now always included in update payloads for:
CSS editor, LED target, HA light target, simple calibration,
advanced calibration
Introduce BindableFloat abstraction that allows any numeric property to be
either a static value or dynamically driven by a ValueSource. Backward-compatible
serialization: plain float when unbound, {value, source_id} dict when bound.
Backend:
- storage/bindable.py — BindableFloat dataclass + bfloat() helper
- 25+ scalar properties converted across all entity types
- Runtime VS acquisition in ColorStripStreamManager for CSS bindings
- All stream hot loops use self.resolve() for live values
- KeyColorsColorStripStream now inherits ColorStripStream
Frontend:
- BindableScalarWidget (slider + VS picker toggle) for all editors
- TypeScript BindableFloat type + helpers
- Graph editor edges for all bindable properties
- Audio source channel IconSelect grid
Fixes: daylight longitude, candlelight wind_strength/candle_type from_dict

- Card crosslinks for HA source, CSS source, brightness VS
- HA connection status icon, text metrics (Hz, uptime)
- Brightness value source selector in editor
New output target type `ha_light` that sends averaged LED colors to HA
light entities via WebSocket service calls (light.turn_on/turn_off):
Backend:
- HARuntime.call_service(): fire-and-forget WS service calls
- HALightOutputTarget: data model with light mappings, update rate, transition
- HALightTargetProcessor: processing loop with delta detection, rate limiting
- ProcessorManager.add_ha_light_target(): registration
- API schemas/routes updated for ha_light target type
Frontend:
- HA Light Targets section in Targets tab tree nav
- Modal editor: HA source picker, CSS source picker, light entity mappings
- Target cards with start/stop/clone/edit actions
- i18n keys for all new UI strings
Add full Home Assistant integration via WebSocket API:
- HARuntime: persistent WebSocket client with auth, auto-reconnect, entity state cache
- HAManager: ref-counted runtime pool (like WeatherManager)
- HomeAssistantCondition: new automation trigger type matching entity states
- REST API: CRUD for HA sources + /test, /entities, /status endpoints

- Center settings tab bar, reduce tab padding for 6-tab fit
- External URL save button: icon button instead of full-width text button
- Remove redundant settings footer close button
- Footer "Source Code" link replaced with "About" opening settings
- i18n keys for en/ru/zh
Replace plain <input type="file"> with a styled drag-and-drop zone
featuring hover/drag states, file info display, and remove button.
Fix 10 review issues: add 401 handling to upload, remove non-null
assertions, add missing i18n keys (common.remove, error.play_failed,
error.download_failed), normalize close button glyphs to ✕,
i18n the dropzone aria-label, replace silent error catches with toast
notifications, use DataTransfer for cross-browser file assignment.
- Replace URL-based image_source/url fields with image_asset_id/video_asset_id
on StaticImagePictureSource and VideoCaptureSource (clean break, no migration)
- Resolve asset IDs to file paths at runtime via AssetStore.get_file_path()
- Add EntitySelect asset pickers for image/video in stream editor modal
- Add notification sound configuration (global sound + per-app overrides)
- Unify per-app color and sound overrides into single "Per-App Overrides" section
- Persist notification history between server restarts
- Add asset management system (upload, edit, delete, soft-delete)
- Replace emoji buttons with SVG icons throughout UI
- Various backend improvements: SQLite stores, auth, backup, MQTT, webhooks
API Input:
- Add interpolation mode (linear/nearest/none) for LED count mismatch
between incoming data and device LED count
- New IconSelect in editor, i18n for en/ru/zh
- Mark crossfade as won't-do (client owns temporal transitions)
- Mark last-write-wins as already implemented
LED Preview:
- Fix zone-mode preview parsing composite wire format (0xFE header
bytes were rendered as color data, garbling multi-zone previews)
- Fix _restoreLedPreviewState to handle zone-mode panels
FPS Charts:
- Seed target card charts from server metrics-history on first load
- Add fetchMetricsHistory() with 5s TTL cache shared across
dashboard, targets, perf-charts, and graph-editor
- Fix chart padding: pass maxSamples per caller (120 for dashboard,
30 for target cards) instead of hardcoded 120
- Fix dashboard chart empty on tab switch (always fetch server history)
- Left-pad with nulls for consistent chart width across targets
Dashboard:
- Fix metrics row alignment (grid layout with fixed column widths)
- Fix FPS label overflow into uptime column
- Add warm, cool, neon, pastel built-in gradients (promoted from frontend presets)
- Change gradient seeding to add missing built-ins on every startup (not just first run)
- Add searchable option to IconSelect component for filtering by name
- Enable search on gradient, effect palette, and audio palette pickers
- Simplify modal titles: "Add Gradient" / "Edit Gradient" instead of "Add Color Strip Source: Gradient"
- Update INSTALLATION.md and .env.example
- Replace truncated plaintext release notes with full-screen overlay
rendered via `marked` library
- Server reconnection does a hard page reload instead of custom event
Replace 22 individual JSON store files with a single SQLite database
(data/ledgrab.db). All entity stores now use BaseSqliteStore backed by
SQLite with WAL mode, write-through caching, and thread-safe access.
- Add Database class with SQLite backup/restore API
- Add BaseSqliteStore as drop-in replacement for BaseJsonStore
- Convert all 16 entity stores to SQLite
- Move global settings (MQTT, external URL, auto-backup) to SQLite
settings table
- Replace JSON backup/restore with SQLite snapshot backups (.db files)
- Remove partial export/import feature (backend + frontend)
- Update demo seed to write directly to SQLite
- Add "Backup Now" button to settings UI
- Remove StorageConfig file path fields (single database_file remains)
- Add unfreeze_saves() to base_store.py and call it in e2e cleanup.
The backup restore flow calls freeze_saves() which sets a module-level
flag that silently disables all store _save() calls. Without reset,
this poisoned all subsequent persistence tests (9 failures).
- Fix os_listener toggle to use toggle-switch/toggle-slider CSS classes
instead of nonexistent switch/slider classes (was showing plain checkbox).
- Add mandatory test run to CLAUDE.md pre-commit checks.
All 341 tests now pass.
The os_listener field existed in the backend model but was never
exposed in the UI. It defaulted to false, so OS notifications were
captured to history but never fired the visual effect. Now shows
a toggle at the top of the notification section, defaults to ON
for new sources.
New audio source type that filters a parent source to a specific frequency
band (bass 20-250Hz, mid 250-4kHz, treble 4k-20kHz, or custom range).
Supports chaining with frequency range intersection and cycle detection.
Band filtering applied in both CSS audio streams and test WebSocket.
New standalone WeatherSource entity with pluggable provider architecture
(Open-Meteo v1, free, no API key). Full CRUD, test endpoint, browser
geolocation, IconSelect provider picker, CardSection with test/clone/edit.
WeatherColorStripStream maps WMO weather codes to ambient color palettes
with temperature hue shifting and thunderstorm flash effects. Ref-counted
WeatherManager polls API and caches data per source.
CSS editor integration: weather type with EntitySelect source picker,
speed and temperature influence sliders. Backup/restore support.
i18n for en/ru/zh.
- Add /api/v1/system/shutdown endpoint that triggers clean uvicorn exit
- Persist all 15 stores to disk during shutdown via _save_all_stores()
- Add force parameter to BaseJsonStore._save() to bypass restore freeze
- Restart script now requests graceful shutdown via API (15s timeout),
falls back to force-kill only if server doesn't exit in time
- Broadcast server_restarting event over WebSocket before shutdown
- Frontend shows "Server restarting..." overlay instantly on WS event,
replacing the old dynamically-created overlay from settings.ts
- Add server_ref module to share uvicorn Server + TrayManager refs
- Add i18n keys for restart overlay (en/ru/zh)
Replace the gradient stop editor (canvas, markers, stop list) in the
CSS editor gradient section with a simple gradient entity selector.
Gradients are now created/edited exclusively in the Gradients tab.
Fix effect and audio palette pickers to populate from gradient entities
dynamically instead of hardcoded HTML options.
Unify all gradient/palette pickers via _buildGradientEntityItems().
Also: rename "None (use own speed)" → "None (no sync)" for sync clocks.
Add i18n keys for gradient selector and missing error messages.
Add full gradient editor modal with name, description, visual stop
editor, tags, and dirty checking. Gradient editor now supports ID
prefix to avoid DOM conflicts between CSS editor and standalone modal.
Fix color picker popover clipped by template-card overflow:hidden.
Fix gradient canvas not sizing correctly in standalone modal.
New notification effects:
- Chase: light bounces across strip with Gaussian glow tail
- Gradient flash: bright center fades to edges with exponential decay
Queue priority: notifications with color_override get high priority and
interrupt the current effect.
Also fixes transient preview for notification sources — adds WebSocket
"fire" command so inline preview works without a saved source, plus
auto-fires on preview open so the effect is visible immediately.
Effects: add 7 new procedural effects (rain, comet, bouncing ball, fireworks,
sparkle rain, lava lamp, wave interference) and custom palette support via
user-defined [[pos,R,G,B],...] stops.
Gradient: add easing functions (linear, ease_in_out, step, cubic) for stop
interpolation, plus noise_perturb and hue_rotate animation types.
Daylight: add longitude field and NOAA solar equations for accurate
sunrise/sunset based on latitude, longitude, and day of year.
Candlelight: add wind simulation (correlated gusts), candle type presets
(taper/votive/bonfire), and wax drip effect with localized brightness dips.
Also fixes editor preview to include all new fields for inline LED test.
Add 5 WebGL shader background effects (Aurora, Plasma, Digital Rain,
Starfield, Warp Tunnel) via a new bg-shaders.ts engine that shares
a dedicated canvas. Add 5 style presets (Sakura, Ocean, Copper, Vapor,
Monolith) with distinctive font pairings. Remove CSS particles effect
in favor of shader-based alternatives. Fix dot grid visibility and
tune all shader intensities for subtle ambient appearance.
Add style presets (font + color combinations) and background effect
presets as a new Appearance tab in the settings modal. Style presets
include Default, Midnight, Ember, Arctic, Terminal, and Neon — each
with curated dark/light theme colors and Google Font pairings.
Background effects (Dot Grid, Gradient Mesh, Scanlines, Particles)
use a dedicated overlay div alongside the existing WebGL Noise Field.
All choices persist to localStorage and restore on page load.
Auth is now optional: when `auth.api_keys` is empty, all endpoints are
open (no login screen, no Bearer tokens). Health endpoint reports
`auth_required` so the frontend knows which mode to use.
Backup/restore fixes:
- Auto-backup uses atomic writes (was `write_text`, risked corruption)
- Startup backup skipped if recent backup exists (<5 min cooldown),
preventing rapid restarts from rotating out good backups
- Restore rejects all-empty backups to prevent accidental data wipes
- Store saves frozen after restore to prevent stale in-memory data
from overwriting freshly-restored files before restart completes
- Missing stores during restore logged as warnings
- STORE_MAP completeness verified at startup against StorageConfig
- Notification history: replace text buttons with icon buttons, use modal-footer for proper positioning
- CSS test: reject 0-LED picture sources with clear error message, show WS close reason in UI
- Calibration: distribute LEDs by aspect ratio (16:9 default) instead of evenly across edges
- Value source schedule: replace native time input with custom HH:MM picker matching automation style
- Remove "No ... yet" empty state labels from all CardSection instances
- Refactor process-picker.ts into generic NamePalette with two concrete
instances: ProcessPalette (running processes) and NotificationAppPalette
(OS notification history apps)
- Notification color strip app colors and filter list now use
NotificationAppPalette (shows display names like "Telegram" instead of
process names like "telegram.exe")
- Fix case-insensitive matching for app_colors and app_filter_list in
notification_stream.py
- Compact browse/remove buttons in notification app color rows with
proper search icon
- Remove old inline process-picker HTML/CSS (replaced by palette overlay)

UI fixes:
- Automation card badge moved to flex layout — title truncates, badge stays visible
- Automation condition pills max-width increased to 280px
- Dashboard crosslinks fixed: pass correct sub-tab key (led-targets not led)
- navigateToCard only skips data load when tab already has cards in DOM

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Backend:
- VideoCaptureSource dataclass with url, loop, playback_speed, start/end_time,
resolution_limit, clock_id, target_fps fields
