Allow composite sources to reference other composite/mapped sources as
layers. Adds cycle detection (via transitive dependency graph walk),
depth limiting (MAX_COMPOSITE_DEPTH=4), and a runtime safety net in the
stream manager. Frontend layer dropdown now shows all source types
except the source being edited.
17 new tests covering cycles, depth limits, and valid nesting — all
715 tests passing.
Introduces a new "group" device type that aggregates multiple physical
(or nested group) devices into one virtual device. Supports two modes:
- Sequence: LEDs concatenated end-to-end (led_count = sum of children)
- Independent: full pixel array resampled to each child independently
Includes cycle detection (DFS) to prevent circular group references,
delete protection for devices referenced by groups, recursive LED count
resolution for nested groups, and reorder controls (move up/down) for
child devices in the UI.
Backend: Device model, API schemas, GroupLEDClient, GroupDeviceProvider,
route validation, processing pipeline integration.
Frontend: type picker, child device picker with reorder, mode selector,
i18n (en/ru/zh), layers icon, CSS for group child rows.
Tests: 20 unit tests for cycle detection, LED count resolution, and
GroupLEDClient (sequence slicing, independent resampling, cleanup).
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
- Game integration editor modal with adapter picker, config fields, event mappings
- game_event source type in CSS and ValueSource editors
- Setup instructions overlay (markdown rendered)
- Live event monitor and connection test
API:
- Full CRUD for game integrations
- Event ingestion endpoint (adapter-level auth)
- Adapter metadata, presets, auto-setup, status/diagnostics endpoints
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

- Add BaseSqliteStore as drop-in replacement for BaseJsonStore
- Convert all 16 entity stores to SQLite

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.

via the OpenRGB SDK server (TCP port 6742). Includes auto-discovery,
health monitoring, state snapshot/restore, and fast synchronous pixel
send with brightness scaling. Also updates TODO.md with complexity notes.
