## v0.3.0 (2026-05-15)

### Migration / Behavior Changes
- Each physical monitor is now its own Home Assistant device, linked to the media-server hub via `via_device`. Existing brightness and power entities migrate to per-display devices automatically on first reload — `unique_id`s are preserved, but entities will move under new devices in the UI and can be placed in their own area/room ([4156ded](https://git.dolgolyov-family.by/alexei.dolgolyov/haos-hacs-integration-media-player/commit/4156ded))
- The hub keeps the `media_player` and script buttons; per-display devices hold the power switch, brightness slider, and the new DDC/CI capability entities ([4156ded](https://git.dolgolyov-family.by/alexei.dolgolyov/haos-hacs-integration-media-player/commit/4156ded))

### Features
- **New diagnostic sensors**: `DisplayResolutionSensor` exposes the active resolution parsed from EDID ([4156ded](https://git.dolgolyov-family.by/alexei.dolgolyov/haos-hacs-integration-media-player/commit/4156ded))
- **New diagnostic binary sensors**: `DisplayPrimaryBinarySensor` and `DisplayPowerControlBinarySensor` make it visible why a power switch is or isn't created for a given display ([4156ded](https://git.dolgolyov-family.by/alexei.dolgolyov/haos-hacs-integration-media-player/commit/4156ded))
- **New select entities**:
  - `DisplayInputSourceSelect` — switch active input (HDMI1, DP1, etc.) via DDC/CI
  - `DisplayColorPresetSelect` — color temperature presets
  - `DisplayPictureModeSelect` — VCP 0xDC scene modes ([4156ded](https://git.dolgolyov-family.by/alexei.dolgolyov/haos-hacs-integration-media-player/commit/4156ded))
- **New number entity**: `DisplayContrastNumber` exposed alongside the existing brightness slider ([4156ded](https://git.dolgolyov-family.by/alexei.dolgolyov/haos-hacs-integration-media-player/commit/4156ded))
- Per-display devices now show real manufacturer/model pulled from EDID; device names no longer prepend the hub title (the hierarchy is already shown via `via_device`) ([4156ded](https://git.dolgolyov-family.by/alexei.dolgolyov/haos-hacs-integration-media-player/commit/4156ded))
- Select and number entities verify the server's `success` flag and re-sync from the actual monitor state when a write is silently rejected — some monitors honor DDC/CI reads but ignore writes for certain codes ([4156ded](https://git.dolgolyov-family.by/alexei.dolgolyov/haos-hacs-integration-media-player/commit/4156ded))

### Performance
- `api_client` no longer forces `?refresh=true` on every poll, letting the integration ride the media server's TTL cache instead of triggering a full DDC/CI probe per entity update ([4156ded](https://git.dolgolyov-family.by/alexei.dolgolyov/haos-hacs-integration-media-player/commit/4156ded))
