+
+## Project Overview
+
+**HA Entity Scanner & Manager** — Webapp self-hosted (Docker) pour scanner, lister, filtrer et gérer les entités Home Assistant. UI en français, orientée admin.
+
+Spécification complète : `consigne.md`
+
+## Tech Stack
+
+- **Backend** : Python FastAPI, SQLite (SQLModel/SQLAlchemy), client HA REST + WebSocket
+- **Frontend** : Vue 3 + Vite
+- **Déploiement** : Docker + docker-compose
+- **Config** : variables d'environnement `HA_BASE_URL`, `HA_TOKEN`
+
+## Architecture
+
+Backend API (FastAPI) + Frontend SPA (Vue 3), séparés. Le backend sert de proxy vers Home Assistant — le token HA ne doit jamais être exposé côté frontend.
+
+### Endpoints backend
+
+| Méthode | Route | Description |
+|---------|-------|-------------|
+| GET | `/api/health` | État app + état HA |
+| POST | `/api/scan` | Lance un scan asynchrone |
+| GET | `/api/entities` | Liste paginée + filtres (query params) |
+| GET | `/api/entities/{entity_id}` | Détails entité |
+| POST | `/api/entities/actions` | Actions bulk (disable/enable/hide/favorite…) |
+| GET | `/api/audit` | Journal des actions |
+
+### Base de données SQLite
+
+- `entities_cache` : cache des entités HA (entity_id PK, domain, friendly_name, state, attrs_json, timestamps)
+- `entity_flags` : flags locaux (ignored, favorite, notes)
+- `audit_log` : historique des actions (action, entity_ids, result, error)
+
+### Désactivation des entités
+
+Deux modes selon le type d'entité :
+1. **Désactivation réelle** via entity_registry/device_registry (WebSocket API HA) quand possible
+2. **Fallback** : masquage/ignore local (flag en DB) — l'UI doit indiquer clairement le mode utilisé
+
+## Build & Run Commands
+
+```bash
+# Docker
+docker-compose up --build
+docker-compose down
+
+# Backend (dev)
+cd backend
+pip install -r requirements.txt
+uvicorn app.main:app --reload --port 8000
+
+# Frontend (dev)
+cd frontend
+npm install
+npm run dev
+
+# Tests
+cd backend
+pytest
+pytest tests/test_entities.py -k "test_parse"  # test unique
+```
+
+## Development Order (from spec)
+
+1. Backend : health + scan + entities list
+2. Frontend : page liste + filtres + détails
+3. Flags locaux (ignore/favorite)
+4. Désactiver/masquer via API HA officielle
+5. Audit log + finitions UI
+
+## Key Constraints
+
+- UI langue française uniquement
+- Scan asynchrone — ne jamais bloquer l'UI
+- Token HA en variable d'environnement, jamais dans le HTML/JS
+- CORS maîtrisé côté backend
+- Toute action sur une entité doit être journalisée dans `audit_log`

+# HA Entity Scanner & Manager
+
+Webapp self-hosted pour scanner, lister, filtrer et gérer les entités Home Assistant.
+UI en français, orientée admin.
+
+## Fonctionnalités
+
+- **Scanner** les entités HA (REST API + WebSocket registry)
+- **Lister** avec tri, pagination, recherche texte
+- **Filtrer** par domaine, état, disponibilité, device_class, intégration, zone
+- **Gérer** : favori, ignorer, désactiver/réactiver
+- **Désactivation** via HA entity_registry (WebSocket) avec fallback local
+- **Journal** des actions (audit log)
+
+## Installation (Docker)
+
+```bash
+# Cloner le projet
+git clone <url> && cd ha_explore
+
+# Configurer
+cp .env.example .env
+# Éditer .env avec votre HA_BASE_URL et HA_TOKEN
+
+# Lancer
+docker-compose up --build
+```
+
+L'application est accessible sur `http://localhost:8080`.
+
+## Variables d'environnement
+
+| Variable | Description | Défaut |
+|----------|-------------|--------|
+| `HA_BASE_URL` | URL de Home Assistant | `http://10.0.0.2:8123` |
+| `HA_TOKEN` | Token d'accès longue durée HA | (requis) |
+
+## Développement
+
+### Backend
+
+```bash
+cd backend
+python -m venv venv && source venv/bin/activate
+pip install -r requirements.txt
+uvicorn app.main:app --reload --port 8000
+```
+
+### Frontend
+
+```bash
+cd frontend
+npm install
+npm run dev
+```
+
+Le frontend (port 5173) proxy les appels `/api` vers le backend (port 8000).
+
+### Tests
+
+```bash
+cd backend
+pytest -v
+```
+
+## Architecture
+
+```
+frontend/     Vue 3 + Vuetify 3 (SPA)
+backend/      FastAPI + SQLite (SQLModel)
+  app/
+    routers/  health, scan, entities, actions, audit
+    services/ scanner, entity_actions
+    models.py, database.py, ha_client.py, config.py
+```
+
+## API Endpoints
+
+| Méthode | Route | Description |
+|---------|-------|-------------|
+| GET | `/api/health` | État app + connexion HA + statut scan |
+| POST | `/api/scan` | Lance un scan asynchrone (202) |
+| GET | `/api/entities` | Liste paginée + filtres |
+| GET | `/api/entities/{id}` | Détails d'une entité |
+| POST | `/api/entities/actions` | Actions bulk (disable/enable/favorite/ignore) |
+| GET | `/api/audit` | Journal des actions |
+
+## Limitations
+
+### Désactivation des entités
+
+Deux modes existent selon le type d'entité :
+
+1. **Désactivation HA réelle** : via `config/entity_registry/update` (WebSocket).
+   Fonctionne pour les entités enregistrées dans le registry HA.
+   L'entité est marquée `disabled_by: "user"` côté HA.
+
+2. **Fallback local** : si la désactivation via registry échoue (entité non enregistrée, erreur WS),
+   l'entité est marquée `ignored_local: true` en base locale.
+   Elle reste active côté HA mais est masquée dans l'app.
+
+L'UI indique clairement le mode utilisé via des badges distincts.

+# CONSIGNE — Claude Code — Webapp “HA Entity Scanner & Manager”
+
+## Objectif
+Développer une webapp self-hosted (Docker) qui se connecte à Home Assistant (URL : `http://10.0.0.2:8123` et token:eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJhNjI1NzkyYjZhZmE0MTliOTEwMmFiMGQ4YjExNDZjNiIsImlhdCI6MTc3MTY4MTE2NSwiZXhwIjoyMDg3MDQxMTY1fQ.uus2-4HCDFajj2oFPiiW9b3KjhxF-DdhFN0XuZ_n5E8) pour :
+1) **Scanner / récupérer** la liste des entités,
+2) **Afficher** une page web avec **liste + filtres**,
+3) Permettre de **désactiver** une ou plusieurs entités (ou, si la désactivation native n’est pas possible via API HA, fournir une alternative fiable et clairement indiquée à l’utilisateur).
+
+## Contraintes et attentes générales
+- Langue UI : **français**.
+- UI : claire, orientée “admin”, table + panneaux, responsive.
+- Architecture standard : **Backend API + Frontend**.
+- Stockage : **SQLite** par défaut (persistant via volume Docker).
+- Auth : au minimum **token HA** côté backend (jamais exposé côté frontend). Idéalement variable d’environnement.
+- Journalisation : logs backend lisibles + page “Journal” simple (dernières actions : scan, désactivation, erreurs).
+- Fournir un **README** (installation, variables d’env, utilisation).
+- Ne jamais bloquer l’UI : scan asynchrone + état d’avancement.
+
+## Périmètre fonctionnel (MVP)
+### A. Connexion Home Assistant
+- Paramètres :
+  - `HA_BASE_URL = http://10.0.0.2:8123`
+  - `HA_TOKEN = eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJhNjI1NzkyYjZhZmE0MTliOTEwMmFiMGQ4YjExNDZjNiIsImlhdCI6MTc3MTY4MTE2NSwiZXhwIjoyMDg3MDQxMTY1fQ.uus2-4HCDFajj2oFPiiW9b3KjhxF-DdhFN0XuZ_n5E8`
+- Tester la connexion via l’API REST Home Assistant.
+- Si erreur : message UI explicite (HTTP code + cause probable).
+
+### B. Récupération des entités
+- Récupérer la liste des entités (au minimum : `entity_id`, `state`, `attributes`, `last_changed`, `last_updated`).
+- Normaliser les champs utiles pour l’affichage :
+  - `domain` (ex: light, switch, sensor)
+  - `friendly_name`
+  - `device_class`, `unit_of_measurement`, `icon`
+  - `area_id` / `device_id` / `integration` si accessibles (sinon marquer “non disponible”)
+  - booléen `is_hidden` / `is_disabled` / `is_available` si déductible
+- Mettre en cache en base (table `entities_cache`) et timestamp du dernier scan.
+
+### C. UI de listing + actions
+- Page principale : tableau (virtualisé si besoin) avec colonnes configurables.
+- Action : sélection multiple (checkbox) + actions en lot :
+  - “Désactiver”
+  - “Réactiver” (si applicable)
+  - “Masquer (UI)” (fallback si désactivation native impossible)
+- Afficher un panneau “Détails” à droite quand on clique une entité :
+  - attributs bruts JSON
+  - infos clés (domain, nom, device_class, etc.)
+  - boutons d’action sur cette entité
+
+## “Désactiver une entité” — règles d’implémentation
+Home Assistant n’offre pas toujours une “désactivation” universelle via une simple API REST. Claude Code doit :
+
+1) **Rechercher la méthode la plus correcte** selon le type d’entité :
+   - Si l’entité est gérable via **registry** (entity_registry / device_registry) via WebSocket API, utiliser la méthode officielle.
+   - Sinon, proposer un **fallback** :
+     - “Masquer” (côté HA si possible via registry) ou “Ignorer dans l’app” (flag local DB) avec libellé clair.
+     - Option “Désactiver en empêchant les services” : non (trop intrusif) sauf si explicitement demandé.
+2) L’UI doit **indiquer clairement** ce que fait l’action (désactivation HA réelle vs masquage/ignore local).
+3) Toute action doit être **journalisée** (quoi, qui, quand, résultat, erreur).
+
+## Brainstorming — filtres “judicieux” à implémenter
+Implémenter une barre de filtres combinables + chips actives :
+1) **Recherche texte** (entity_id, friendly_name).
+2) **Domain** (multi-select) : light/switch/sensor/… + compteur par domaine.
+3) **État** :
+   - `state` exact (on/off/…)
+   - “Indisponible” (`unavailable`, `unknown`)
+4) **Disponibilité** :
+   - disponibles vs indisponibles
+5) **Dernier changement** :
+   - “modifié dans les 5 min / 1 h / 24 h”
+6) **Attributs** :
+   - `device_class` (multi-select)
+   - `unit_of_measurement` (multi-select)
+7) **Source / intégration** (si accessible) :
+   - ZHA / Zigbee2MQTT / ESPHome / MQTT / Tapo / Reolink / …
+8) **Zone / Pièce** (area) si accessible.
+9) **Entités problématiques** (smart filters) :
+   - “spam logbook” : change très souvent (détecter fréquence)
+   - “entités orphelines” : pas de device_id / integration inconnue
+   - “noms manquants” : pas de friendly_name
+10) **Statut de gestion** (dans l’app) :
+   - “Désactivées”
+   - “Masquées”
+   - “Ignorées localement”
+11) **Favoris** :
+   - Marquer favori (flag local) pour accès rapide.
+
+## UX attendue
+- En-tête :
+  - bouton “Scanner maintenant”
+  - indicateur “Dernier scan : …”
+  - statut connexion HA (OK/KO)
+- Zone filtres :
+  - champ recherche + filtres en dropdown + chips
+- Table :
+  - tri colonnes (domain, nom, last_changed, state)
+  - pagination ou virtual scroll
+  - multi-sélection + actions groupées
+- Panneau latéral détails :
+  - affichage propre des attributs JSON
+  - actions rapides (désactiver/masquer/ignorer/favori)
+
+## Tech recommandée (choix par défaut)
+- Backend : **Python FastAPI**
+  - Client HA via REST + WebSocket (si nécessaire pour registry)
+  - SQLite via SQLModel ou SQLAlchemy
+- Frontend : **Vue 3 + Vite** (ou React si préféré), UI simple
+- Docker :
+  - `docker-compose.yml` avec volumes (db + config)
+  - variables d’environnement pour `HA_BASE_URL`, `HA_TOKEN`
+
+## Endpoints backend (à produire)
+- `GET /api/health` : état de l’app + état HA
+- `POST /api/scan` : lance un scan (asynchrone)
+- `GET /api/entities` : liste paginée + filtres (query params)
+- `GET /api/entities/{entity_id}` : détails
+- `POST /api/entities/actions` : actions bulk (disable/enable/hide/unhide/ignore/unignore/favorite/unfavorite)
+- `GET /api/audit` : dernières actions
+
+## Données (SQLite)
+Tables minimales :
+- `entities_cache` : entity_id (PK), domain, friendly_name, state, attrs_json, last_changed, last_updated, fetched_at
+- `entity_flags` : entity_id (PK), ignored_local (bool), favorite (bool), notes (text)
+- `audit_log` : id, ts, action, entity_ids_json, result, error
+
+## Exigences qualité
+- Gestion d’erreurs explicite (HA down, token invalide, timeout).
+- Timeout réseau configurable.
+- Tests minimaux :
+  - test de parsing entités
+  - test filtre domain/state
+  - test “action bulk” (mock HA)
+- Sécurité :
+  - le token HA ne doit jamais apparaître dans le HTML/JS.
+  - CORS maîtrisé.
+
+## Livrables attendus
+- Arborescence projet complète.
+- `docker-compose.yml`
+- Backend FastAPI prêt à lancer.
+- Frontend page unique fonctionnelle.
+- `README.md` clair.
+- Une section “Limitations” expliquant la différence entre :
+  - désactivation réelle HA via registry (si implémentée)
+  - masquage/ignore local si non possible selon entité.
+
+## Ordre de réalisation imposé
+1) Backend : health + scan + entities list (sans disable)
+2) Frontend : page liste + filtres + détails
+3) Ajout flags locaux (ignore/favorite)
+4) Implémenter “désactiver/masquer” via API HA la plus officielle possible
+5) Audit log + finitions UI + README final

+# Design — HA Entity Scanner & Manager
+
+**Date** : 2026-02-21
+**Statut** : Approuvé
+
+## Architecture globale
+
+```
+Frontend (Vue 3 + Vuetify 3)  ──►  Backend (FastAPI)  ──►  Home Assistant
+       SPA :5173                    API :8000                  :8123
+                                    SQLite DB                REST + WS
+```
+
+- **Frontend** : SPA Vue 3 + Vite + Vuetify 3, appelle `/api/*`
+- **Backend** : FastAPI, proxy sécurisé vers HA (token jamais exposé côté client)
+- **DB** : SQLite via SQLModel, 3 tables (entities_cache, entity_flags, audit_log)
+- **Client HA** : `aiohttp` pour REST (`/api/states`) et WebSocket (`/api/websocket`)
+- **Déploiement** : Docker + docker-compose, variables d'env `HA_BASE_URL` / `HA_TOKEN`
+
+## Backend — structure des modules
+
+| Module | Responsabilité |
+|--------|---------------|
+| `app/main.py` | App FastAPI, CORS, lifespan |
+| `app/config.py` | Settings via pydantic-settings (env vars) |
+| `app/models.py` | SQLModel : EntityCache, EntityFlag, AuditLog |
+| `app/database.py` | Init SQLite, get_session |
+| `app/ha_client.py` | Client aiohttp : REST states + WS registry |
+| `app/routers/health.py` | `GET /api/health` |
+| `app/routers/scan.py` | `POST /api/scan` (async background task) |
+| `app/routers/entities.py` | `GET /api/entities`, `GET /api/entities/{id}` |
+| `app/routers/actions.py` | `POST /api/entities/actions` |
+| `app/routers/audit.py` | `GET /api/audit` |
+| `app/services/scanner.py` | Logique scan : fetch + normalize + upsert DB |
+| `app/services/entity_actions.py` | Logique disable/enable/hide via WS ou fallback |
+
+## Frontend — composants principaux
+
+| Composant | Rôle |
+|-----------|------|
+| `App.vue` | Layout principal, header avec statut HA |
+| `EntityTable.vue` | `v-data-table-server` avec tri, pagination, sélection |
+| `FilterBar.vue` | Recherche texte + dropdowns domaine/état + chips actives |
+| `EntityDetail.vue` | Panneau latéral détails + actions |
+| `AuditLog.vue` | Page journal des actions |
+| `ScanButton.vue` | Bouton scan + indicateur progression |
+
+## Base de données SQLite
+
+### entities_cache
+- `entity_id` (PK), `domain`, `friendly_name`, `state`
+- `attrs_json` (TEXT — attributs HA complets)
+- `device_class`, `unit_of_measurement`, `area_id`, `device_id`, `integration`
+- `is_disabled`, `is_hidden`, `is_available` (booléens déduits)
+- `last_changed`, `last_updated`, `fetched_at`
+
+### entity_flags
+- `entity_id` (PK), `ignored_local` (bool), `favorite` (bool), `notes` (text)
+
+### audit_log
+- `id` (PK auto), `ts` (datetime), `action` (text), `entity_ids_json` (text), `result` (text), `error` (text)
+
+## Scan asynchrone
+
+`POST /api/scan` lance une `BackgroundTask` FastAPI. Un état en mémoire (`idle`/`scanning`/`done`/`error` + progression) est exposé via `GET /api/health`. Le frontend poll le health pour afficher la progression.
+
+## Désactivation des entités
+
+1. **Méthode principale** : WS API HA `config/entity_registry/update` avec `disabled_by: "user"`
+2. **Fallback** : flag `ignored_local=true` en DB locale
+3. L'UI affiche un badge distinct selon le mode utilisé (désactivé HA vs ignoré local)
+4. Toute action journalisée dans `audit_log`
+
+## Choix techniques
+
+- **Python FastAPI** + **aiohttp** (client HA REST + WS)
+- **SQLModel** (SQLAlchemy + Pydantic)
+- **Vue 3** + **Vite** + **Vuetify 3**
+- **Docker** + **docker-compose**
+- UI en **français** uniquement
