 - Use `ha-dialog`.
 - Use `DialogMixin`, which implements `HassDialogNext<T>`, for new dialogs. See `src/dialogs/dialog-mixin.ts`.
- Read dialog parameters from the mixin's `params` property and render the dialog open. Return `nothing` while required parameters are absent.
- Call the mixin's `closeDialog()` to close a new dialog. The mixin handles the `closed` event, fires `dialog-closed`, and removes the host element.
 - Existing dialogs may implement the legacy `HassDialog<T>` interface from `src/dialogs/make-dialog-manager.ts`.
- Preserve the existing `showDialog()`, open-state, and close-event lifecycle when maintaining a legacy dialog; do not copy that lifecycle into a `DialogMixin` dialog.
+- Use `@state() private _open = false` to control visibility.
+- Set `_open = true` in `showDialog()` and `_open = false` in `closeDialog()`.
+- Return `nothing` while required params are absent.
+- Fire `dialog-closed` in the close handler.
 - Use `header-title` and `header-subtitle` for simple header text.
 - Use slots when standard header attributes are not enough.
 - Use `ha-dialog-footer` with `primaryAction` and `secondaryAction` slots.

-# Demo Agent Instructions
-
-This file applies to all files under `demo/`. Follow the root `AGENTS.md` for repository-wide standards.
-
-The demo is the full Home Assistant frontend running against a mocked backend (published at https://demo.home-assistant.io). It needs no Home Assistant server, which makes it the easiest way to load the real UI in a browser, for example to take screenshots.
-
-## Running the demo
-
-Run from the repository root:
-
-```bash
-yarn dev:demo               # dev server on http://localhost:8090
-yarn dev:demo --background  # detached; also supports --status/--stop/--logs
-```
-
-## Opening a specific demo
-
-The demo contains multiple demo configurations. Select one directly with the `demo` query parameter, e.g. `http://localhost:8090/?demo=<slug>`. The valid slugs are defined in `demoConfigs` in `src/configs/demo-configs.ts`, so "the second demo" means the slug of the second entry in that list. An unknown slug falls back to the default (the first entry).
-
-## Opening a specific page
-
-The demo build uses hash-based routing: the frontend path goes in the URL hash, and the `demo` query parameter goes before the `#`. The URL format is:
-
-```
-http://localhost:8090/?demo=<slug>#/<path>
-```
-
-Useful paths:
-
- `/lovelace/0` — the selected demo's dashboard (also the default when no hash is given)
- `/energy` — energy dashboard. Its tabs are views: `/energy/overview` (Summary), `/energy/electricity`, `/energy/gas`, `/energy/water`, `/energy/now`
- `/map`, `/history`, `/todo`, `/config` — other sidebar panels
-
-Example — the water tab of the energy dashboard of the second demo:
-
-```
-http://localhost:8090/?demo=<second slug>#/energy/water
-```
-
-## Structure
-
- `src/ha-demo.ts`: Root element; sets up all backend mocks.
- `src/configs/<slug>/`: One directory per demo configuration (entities, dashboard, theme).
- `src/configs/demo-configs.ts`: Registry of demo configurations and URL slug handling.
- `src/stubs/`: Mocked WebSocket/REST APIs.
- `script/develop_demo`, `script/build_demo`: Dev server and static build wrappers.
-
-## The gallery imports these stubs too
-
-`demo/src/stubs/` is shared, not demo-private: gallery pages import from it directly. Before changing or removing anything a stub does, grep for its callers across `gallery/` as well as `demo/`, and check the affected gallery pages, not just the demo.
-
-```bash
-grep -rn "stubs/<name>" demo/src gallery/src
-```
-
-The two consume a stub differently, so demo behavior does not predict gallery behavior. A gallery page calls stubs against the `hass` from `provideHass`, where `hass.config` is the shared `demoConfig` object, so a stub that mutates `hass.config` in place is visible to the page. `ha-demo.ts` copies `components` into a new array before the stubs run, so the same mutation never reaches the demo. A change can therefore look fine in the demo while quietly breaking a gallery page.

 Gallery pages are generated by `gather-gallery-pages` in `build-scripts/gulp/gallery.js`.

- A page ID is the path under `gallery/src/pages/` without the extension, like `components/ha-button`.
- A `.markdown` file and a `.ts` file with the same page ID become one gallery page.

 - A page may have only markdown, only a TypeScript demo, or both.
 - Markdown can contain YAML frontmatter with `title` and optional `subtitle`.
 - Markdown that contains only frontmatter contributes metadata without rendering a description block.
 - TypeScript demo modules are dynamically imported for side effects when the page is opened.
 - A demo module must define a custom element named `demo-${category}-${page}` with slashes replaced by hyphens, like `demo-components-ha-button` for `components/ha-button`.
- `gallery/src/ha-gallery.ts` renders that element with `dynamicElement()` based on the current page ID.

-title: Replaced device selectors
-subtitle: How device and target selectors surface devices that were split into separate devices
---
-
-A device that used to belong to multiple config entries is split into one
-device per config entry. The original composite device is removed from the
-registry, so existing references to it (targets in automations, device
-selectors) point at a device that no longer exists.
-
-When a selector holds such a reference, it shows a **replaced** state instead of
-a plain "not found", and offers to point the reference at the replacement
-device(s). The candidate replacements are filtered through the selector's own
-filters, so in practice usually a single device matches:
-
- **Target selector** — the replaced device row offers **Replace**, which adds
-  every replacement device that matches the target filters and removes the old
-  reference.
- **Device selector** — when exactly one replacement matches, **Replace** swaps
-  to it in one click; when several match, a dialog lets you pick one.
-
-All samples below reference the removed composite device `old_composite`, which
-was split into a light device and a switch device.
