Rename the "profiles" entity to "automations" throughout the entire
codebase for clarity. Updates Python models, storage, API routes/schemas,
engine, frontend JS modules, HTML templates, CSS classes, i18n keys
(en/ru/zh), dashboard, tutorials, and command palette.

Profiles now activate scene presets instead of individual targets, with
configurable deactivation behavior (none/revert/fallback scene). The
target checklist UI is replaced by a searchable combobox for scene
selection that scales well with many scenes.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Feature 1 — Profile Conditions: time-of-day, system idle (Win32
GetLastInputInfo), and display state (GUID_CONSOLE_DISPLAY_STATE)
condition types for automatic profile activation.
Feature 2 — Scene Presets: snapshot/restore system that captures target
running states, device brightness, and profile enables. Server-side
capture with 5-step activation order. Dedicated Scenes tab with
CardSection-based card grid, command palette integration, and dashboard
quick-activate section.
Feature 3 — MQTT Integration: MQTTService singleton with aiomqtt,
MQTTLEDClient device provider for pixel output, MQTT profile condition
type with topic/payload matching, and frontend support for MQTT device
type and condition editor.

- Add protocol field (ddp/http) to storage, API schemas, routes, processor
- WledTargetProcessor passes protocol to create_led_client(use_ddp=...)
- Target editor: protocol dropdown + keepalive in collapsible Specific Settings
- FPS, brightness threshold, adaptive FPS moved to main form area
- Hide Specific Settings section for serial devices (protocol is WLED-only)
- Card badge: show DDP/HTTP for WLED devices, Serial for serial devices

DDP uses fire-and-forget UDP, so when a WiFi device becomes overwhelmed
by sustained traffic, sends appear successful while the device is
actually unreachable. This adds:
- HTTP liveness probe (GET /json/info, 2s timeout) every 10s during
streaming, exposed as device_streaming_reachable in target state
- Adaptive FPS (opt-in): exponential backoff when device is unreachable,
gradual recovery when it stabilizes — finds sustainable send rate
- Honest health checks: removed the lie that forced device_online=true
during streaming; now runs actual health checks regardless
- Target editor toggle, FPS display shows effective rate when throttled,
health dot reflects streaming reachability, red highlight when
unreachable
- Auto-backup scheduling support in settings modal
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Backend: GET /api/v1/system/backup bundles all 11 store JSON files into a
single downloadable backup with metadata envelope. POST /api/v1/system/restore
validates and writes stores atomically, then schedules a delayed server restart
via detached restart.ps1 subprocess.
Frontend: Settings modal (gear button in header) with Download Backup and
Restore from Backup buttons. Restore shows confirm dialog, uploads via
multipart FormData, then displays fullscreen restart overlay that polls
/health until the server comes back and reloads the page.
Locales: en, ru, zh translations for all settings.* keys.

Type is set at creation and cannot be changed, so hide the selector
when editing (same pattern already used in value source editor).
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Add real-time value source test: WebSocket endpoint streams get_value() at
~20Hz, frontend renders scrolling time-series chart with min/max/current stats
- Add auto-gain for audio value sources: rolling peak normalization with slow
decay, sensitivity range increased to 0.1-20.0
- Always show brightness overlay on LED preview when brightness source is set
- Refactor ValueStreamManager to shared ref-counted streams (value streams
produce scalars, not LED-count-dependent, so sharing is correct)
- Simplify acquire/release API: remove consumer_id parameter since streams
are no longer consumer-dependent

New per-target property: when effective output brightness
(max pixel value × device/source brightness) falls below
the threshold, LEDs turn off completely. Useful for cutting
dim flicker in audio-reactive and ambient setups.
Threshold slider (0–254) in target editor, badge on card,
hot-swap to running processors, persisted in storage.

Introduces an engine+template abstraction for audio capture, mirroring the
existing screen capture engine pattern. This enables multiple audio backends
(WASAPI for Windows, sounddevice for cross-platform) with per-source
engine configuration via reusable templates.
Backend:
- AudioCaptureEngine ABC with WasapiEngine and SounddeviceEngine implementations
- AudioEngineRegistry for engine discovery and factory creation
- AudioAnalyzer class decouples FFT/RMS/beat analysis from engine-specific capture
- ManagedAudioStream wraps engine stream + analyzer in background thread
- AudioCaptureTemplate model and AudioTemplateStore with JSON CRUD
- AudioCaptureManager keyed by (engine_type, device_index, is_loopback)
- Auto-migration: default template created on startup, assigned to existing sources
- Full REST API: CRUD for audio templates + engine listing with availability flags
- audio_template_id added to MultichannelAudioSource model and API schemas
Frontend:
- Audio template cards in Streams > Audio tab with engine badge and config details
- Audio template editor modal with engine selector and dynamic config fields
- Audio template dropdown in multichannel audio source editor
- Template name crosslink badge on multichannel audio source cards
- Confirm modal z-index fix (always stacks above editor modals)
- i18n keys for EN and RU

Place the overlay button inside the preview screen as a pill toggle,
add it as a tutorial step that auto-skips in device calibration mode.
Tutorial engine now skips hidden/missing targets in both directions.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add min_value and max_value fields to AudioValueSource so audio
brightness can be mapped to a configurable range (e.g. silence =
30% brightness floor instead of fully black).

Virtual device with configurable LED count, RGB/RGBW mode, and simulated
send latency. Includes full provider/client implementation, API schema
support, and frontend add/settings modal integration.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add a 💡 button in the calibration modal header (CSS mode only) that
toggles the LED overlay visualization. Auto-stops overlay on modal close
if started from the dialog. Checks and reflects current overlay status
on modal open.
Fix serial devices creating a new connection on every edge test toggle,
which triggered Arduino bootloader resets. Now reuses the cached idle
client for all device types.

New source_type "api_input" allows external clients to push raw LED
color arrays ([R,G,B] per LED) via REST POST or WebSocket. Includes
configurable fallback color and timeout for automatic revert when no
data is received. Stream auto-sizes LED count from the target device.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Replace single "adaptive" type with adaptive_mode sub-selector by two
distinct source types in the dropdown. Removes the adaptive_mode field
entirely — the source_type itself carries the mode. Clearer UX with
"Adaptive (Time of Day)" and "Adaptive (Scene)" as separate options.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
New "adaptive" value source type that automatically adjusts brightness
based on external conditions. Two sub-modes: time-of-day (schedule-based
interpolation with midnight wrap) and scene brightness (frame luminance
analysis via numpy BT.601 subsampling with EMA smoothing).
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Background task samples system (CPU/RAM/GPU) and per-target (FPS/timing) metrics
every 1s into a 120-sample ring buffer (~2 min). New API endpoint
GET /system/metrics-history returns the buffer. Dashboard charts now seed from
server history on load instead of sessionStorage, surviving page refreshes.
Also removes emoji from brightness source labels.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Extend value source brightness modulation to Key Colors targets (matching LED target support).
Also fix stream subtab CSS selector collision that broke target subtab selection, and use 🔢 emoji
for value source UI elements.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Introduces a new Value Source entity that produces a scalar float (0.0-1.0)
for dynamic brightness modulation. Three subtypes: Static (constant),
Animated (sine/triangle/square/sawtooth waveform), and Audio-reactive
(RMS/peak/beat from mono audio source). Value sources can be optionally
attached to LED targets to control brightness each frame.

Segments are redundant now that the "mapped" CSS type handles spatial
multiplexing internally. Each target now references one color_strip_source_id
instead of an array of segments with start/end/reverse ranges.
Backward compat: existing targets with old segments format are migrated
on load by extracting the first segment's CSS source ID.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Audio sources moved to separate tab with dedicated CRUD API, store, and editor modal
- New "mapped" color strip source type: assigns different CSS sources to distinct LED sub-ranges (zones)
- Mapped stream runtime with per-zone sub-streams, auto-sizing, hot-update support
- Target editor auto-collapses segments UI when mapped CSS is selected
- Delete protection for CSS sources referenced by mapped zones
- Compact header/footer layout

New scrcpy/ADB capture engine that captures Android device screens over
ADB using screencap polling. Supports USB and WiFi ADB connections with
device auto-discovery. Engine-aware display picker shows Android devices
when scrcpy engine is selected, with inline ADB connect form for WiFi
devices.
Key changes:
- New scrcpy_engine.py using adb screencap polling (~1-2 FPS over WiFi)
- Engine-aware GET /config/displays?engine_type= API
- ADB connect/disconnect API endpoints (POST /adb/connect, /adb/disconnect)
- Display picker supports engine-specific device lists
- Stream/test modals pass engine type to display picker
- Test template handler changed to sync def to prevent event loop blocking
- Restart script merges registry PATH for newly-installed tools
- All engines (including unavailable) shown in engine list with status flag

Audio capture now produces per-channel FFT spectrum and RMS alongside
the existing mono mix. Each audio color strip source can select which
channel to visualize via a new "Channel" dropdown. This enables stereo
setups with separate left/right segments on the same LED strip.
Also shows the device LED count under the device selector in the target
editor for quick reference.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Each target now has a segments list where each segment maps a color strip
source to a pixel range (start/end) on the device with optional reverse.
This enables composing multiple visualizations on a single LED strip.
Old targets auto-migrate from the single source format on load.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add new "audio" color strip source type with three visualization modes
(spectrum analyzer, beat pulse, VU meter) supporting WASAPI loopback and
microphone input via PyAudioWPatch. Includes shared audio capture with
ref counting, real-time FFT spectrum analysis, and beat detection.
Improve all referential integrity 409 error messages across delete
endpoints to include specific names of referencing entities instead of
generic "one or more" messages.

Composite sources stack multiple existing color strip sources as layers
with configurable blend modes (Normal, Add, Multiply, Screen) and per-layer
opacity. Includes full CRUD, hot-reload, delete protection for referenced
layers, and pre-allocated integer blend math at 30 FPS.
Also eliminates per-frame numpy allocations in color_strip_stream,
effect_stream, and wled_target_processor (buffer pre-allocation).

LED skip: set first N and last M LEDs to black on a target. Color sources
(static, gradient, effect, color cycle) render across only the active
(non-skipped) LEDs. Processor pads with blacks before sending to device.
Rename standby_interval → keepalive_interval across all Python, API
schemas, and JS. from_dict falls back to old key for existing configs.
Remove legacy migration functions (_migrate_devices_to_targets,
_migrate_targets_to_color_strips) and legacy fields from target model.

Filter Template meta-filter: reference existing PP templates inside others
for composable, DRY filter chains. Filters are recursively expanded at
pipeline build time with cycle detection. New `select` option type with
dynamic choices populated by the API.
Keepalive optimization: serial devices (Adalight, AmbiLED) don't need
keepalive — they hold last frame indefinitely. Check `standby_required`
capability at processor start, skip keepalive sends for serial targets,
and hide keepalive metrics in the UI. Rename "Standby Interval" to
"Keep Alive Interval" throughout the frontend.

New features:
- Procedural effect source type with fire, meteor, plasma, noise, and aurora algorithms
using palette LUT system and 1D value noise generator
- 12 predefined gradient presets (rainbow, sunset, ocean, forest, fire, lava, aurora,
ice, warm, cool, neon, pastel) selectable from a dropdown in the gradient editor
- Auto-crop filter: min aspect ratio parameter to prevent false-positive cropping
in dark scenes on ultrawide displays
Optimization:
- Static/gradient sources without animation: stream thread sleeps 0.25s instead of
frame_time; processor repolls at frame_time instead of 5ms (~40x fewer iterations)
- Inverted isinstance checks in routes to test for PictureColorStripSource only
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Add dynamic "Hardware max ≈ N fps" recommendation below FPS slider,
computed from LED count (WLED: protocol timing) or baud rate (serial).
Reuses shared _computeMaxFps from devices.js with named constants.
- Fix gradient looking different across targets sharing the same stream:
configure() now uses max LED count across all consumers; _fit_to_device
uses np.interp linear interpolation instead of truncate/tile.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Replace animation Enable checkbox with None option in effect selector;
show effect description tooltip; disable speed slider when None selected
- Allow target FPS range 1-90 (was 10-90) across UI and backend validation
- Scope serial COM connections to target lifetime (no idle caching);
use temporary connections for power-off/test mode
- Fix serial black frame on stop: flush after write, delay after task
cancel to prevent race with in-flight thread pool write
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
FPS is a consumption property (how fast to send to a device), not a
production property. Two targets sharing the same source may need
different FPS. This moves the fps field from PictureColorStripSource
to WledPictureTarget across the full stack.
The capture stream now auto-adjusts its rate to max(all connected
target FPS values) via ColorStripStreamManager tracking per-consumer
FPS. UI updates: FPS slider in target editor, FPS badge on target
cards, LED count repositioned in CSS editor, consistent speed icons.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- color_cycle is now a top-level source type (alongside picture/static/gradient)
with a configurable color list and cycle_speed; defaults to full rainbow spectrum
- ColorCycleColorStripSource + ColorCycleColorStripStream: smooth 30 fps interpolation
between user-defined colors, one full cycle every 20s at speed=1.0
- Removed color_cycle animation sub-type from StaticColorStripStream
- Color cycle editor: compact horizontal swatch layout, proper module-scope fix
(colorCycleAdd/Remove now exposed on window, DOM-synced before mutations)
- Animation enabled + Frame interpolation checkboxes use toggle-switch style
- Removed Potential FPS metric from targets and KC targets metric grids

Introduces a new 'static' source type that fills all device LEDs with a
single constant RGB color — no screen capture or processing required.
- StaticColorStripSource storage model (color + led_count=0 auto-size)
- StaticColorStripStream: no background thread, configure() sizes to device
LED count at processor start; hot-updates preserve runtime size
- ColorStripStreamManager dispatches static sources (no LiveStream needed)
- WledTargetProcessor calls stream.configure(device_led_count) on start
- API schemas/routes: source_type Literal["picture","static"]; color field;
overlay/calibration-test endpoints return 400 for static
- Frontend: type selector modal, color picker, type-aware card rendering
(🎨 icon + color swatch), LED count field hidden for static type
- Locale keys: color_strip.type, color_strip.static_color (en + ru)
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Add explicit led_count to PictureColorStripSource (0 = auto from calibration)
- Stream pads with black or truncates to match led_count exactly
- Calibration dialog: show led_count input above visual editor in CSS mode
- Calibration dialog: pre-populate led_count with effective count (cal sum) when stored value is 0
- Calibration dialog: sync preview label live as led_count input changes
- CSS editor: group brightness/saturation/gamma into collapsible "Color Corrections" section
