One device per scene playlist (model "Scene Playlist"), each with:
- a switch (start/stop; the server cycles one playlist at a time, so starting one stops any other)
- a "Current Scene" sensor that resolves the active preset name from scene_presets while this playlist is cycling
- an "Items" diagnostic sensor (configured scene count; no state_class)
The coordinator reads scene_playlists plus the flat playlist_state from the /api/v1/snapshot payload and gains start_playlist()/stop_playlist(); __init__ registers and prunes per-playlist devices and reloads on playlist-id changes; the event listener also refreshes on the playlist_state_changed WS event. Shared device/lookup/running-state plumbing lives in a new LedGrabPlaylistEntity base (entity.py) used by both the switch and the sensors. Adds en/ru translation keys.
Note: this also lands the in-progress coordinator migration from the per-request fan-out to the single /api/v1/snapshot poll that was already present in the working tree.
Requires the led-grab server /api/v1/snapshot to emit scene_playlists + playlist_state (companion server change, tracked separately).
- Server device exposing CPU/RAM/GPU/temperature/battery sensors via
/api/v1/system/performance, plus last-restart timestamp (cached with
jitter threshold so the recorder doesn't see poll wobble) and version.
- Update entity backed by /api/v1/system/update — installs via
/apply, hides the install button when the server reports
can_auto_update=false.
- Sync-clock entities: reset button, speed number, running switch, and
the event listener now refreshes on entity_changed events too.
- Bump manifest to 0.4.0.
HACS-compatible custom component split out from the main LedGrab repo.
Creates light, switch, sensor, number, and select entities for each
configured LedGrab device.
