 ### Immich configuration (lightweight + low power)

-Immich uses an API key and a `/api` base path. This integration requests the asset search endpoint and downloads the configured image size into a local cache before displaying them. That keeps bandwidth and power usage low while still letting `slide` do its normal scaling and transitions.
+Immich uses an API key and a `/api` base path. This integration requests the asset search endpoint and downloads the configured image size into a local cache before displaying them. That keeps bandwidth and power usage low while still letting `slide` do its normal scaling and transitions. If you have RAW/HEIC images, set `size` to `preview`/`thumbnail` or use `extensions` to limit results to JPEG/PNG; `slide` will also fall back to `preview` if a `fullsize` download isn't readable. Immich metadata (EXIF original time / created time) is stored alongside cached assets so `<exifdatetime>` continues to work even if the cached image doesn't contain EXIF data.
+
+#### Getting an Immich API key
+
+In the Immich web UI, go to Settings and find **API Keys** (menu labels can vary by version), then create a new key and copy it.
+
+#### Required API key permissions
+
+`slide` uses Immich search plus the asset view/download endpoints, so the API key should include:
+* `asset.read` — required by Immich search endpoints (used to retrieve asset metadata).
+* `asset.view` — required for the viewAsset endpoint (thumbnail/preview/fullsize).
+* `asset.download` — required if you set `size` to `original` (download endpoint).
+
+#### Finding an Immich user ID
+
+You can use a user ID to show all assets owned by that user.
+
+Common ways to find it:
+* **Admin UI**: In Immich, open the Admin/Users page, click the user, and copy the UUID shown in the user details or URL.
+* **API (non-admin)**: Call the `users/me` endpoint with the API key and read the `id` field:
+```
+curl -H "x-api-key: IMMICH_API_KEY" http://immich.local:2283/api/users/me
+```

+
+This guide adds a Home Assistant dashboard to control `slide` via MQTT (play/pause/next, plus Immich filters).
+
+Default MQTT topics used by `slide`:
+
+- Control: `slide/control`
+- Immich control: `slide/immich`
+
+If you changed topics in your `slide` config, update the YAML below to match.

+## Notes
+
+- If you changed the MQTT topics in `slide`’s config, update all `topic:` entries to match.
+- `extensions` filters by file extension (e.g., `jpg,jpeg,png`) to avoid RAW/HEIC if your display environment can’t decode them.
+- `refreshSeconds` controls how often `slide` refreshes the Immich asset list.
