Fix: Grafana dashboard Orion-LD + Stellio persistence investigation

- ✅ Grafana dashboard updated with proper time filters - ✅ Orion-LD pipeline validated (6 tables, 5+ rows in CrateDB) - ❌ Stellio pipeline blocked: QuantumLeap /v2/notify doesn't support NGSI-LD native format (TypeError: argument of type 'float' is not iterable) - 📝 QuantumLeap expects NGSI-v2 format ({"value": X, "type": "Number"}) but receives NGSI-LD (direct values) Next steps: - Focus on Orion-LD pipeline (working) - Consider Stellio as experimental / future work
ADD: Updated architecture with Stellio pipeline diagram

+# Bilan Smart City - Session 2026-05-05
+
+## ✅ Réalisations
+1. **Traceability (source/mqttTopic)** ajoutée avec succès dans :
+   - Orion-LD (port 2026) ✅
+   - Stellio (port 8087) ✅
+   
+2. **Simulator.py** corrigé :
+   - ORION_CONTEXT nettoyé (sans source dedans)
+   - publish_orion() : PATCH avec @context complet
+   - Suppression entités "zombies" (409 Conflict + 404 Not Found)
+   
+3. **Modern Data Stack** document créé : `references/modern-data-stack.md`
+
+## ❌ Problèmes en cours
+1. **FROST-Server** (port 8090) :
+   - Erreur : `Setting db.jndi.datasource must not be empty`
+   - Cause : Container sur mauvais réseau Docker
+   - Status : **Bloqué** (à réparer plus tard)
+   
+2. **OpenRemote** :
+   - Erreur : `[Errno -2] Name or service not known`
+   - Status : **DNS/Connexion** (à réparer plus tard)
+
+## 📋 Prochaines étapes
+1. Modern Data Stack (MDS) - voir `references/modern-data-stack.md`
+2. Réparer FROST (networking Docker)
+3. Réparer OpenRemote (DNS)
+4. Intégration Grafana avec nouveaux champs source/mqttTopic

+# Bilan Grafana Datasources - 05-05-2026
+
+## Statut
+- ✅ **Prometheus** : Fonctionne (plugin natif, network partagé)
+- ❌ **InfluxDB** : Problèmes de config (read-only + health check fails)
+- ❌ **Orion-LD / FROST / Stellio** : Plugin simple-json INCOMPATIBLE
+
+## Solutions
+
+### InfluxDB
+1. **Problème** : Datasource "read-only" (provisioned)
+2. **Solution A** : Modifier `/etc/grafana/provisioning/datasources/datasources.yaml` dans le container
+3. **Solution B** : Supprimer la datasource provisioned et la recréer via API
+4. **Configurer** :
+   - URL : `http://digital-twin-influxdb:8086`
+   - Version : `Flux` (v2)
+   - Organization : `smartcity`
+   - DefaultBucket : `smartcity`
+   - Token : (récupérer depuis container InfluxDB)
+
+### Orion-LD / FROST / Stellio (NGSI-LD / SensorThings)
+**NE PAS utiliser** `grafana-simple-json-datasource` (incompatible).
+
+**À FAIRE** :
+1. **Option 1** : Installer plugin NGSI-LD dédié (si existe)
+2. **Option 2** : Créer un micro-service adaptateur (Node.js/Python) qui :
+   - Implémente l'API simple-json
+   - Traduit les requêtes vers NGSI-LD/SensorThings
+   - Expose sur un port (ex: 9000)
+3. **Option 3** : Utiliser l'API HTTP directement dans un panel :
+   - Installer plugin "JSON API" dans Grafana
+   - Faire des requêtes GET vers les APIs
+   - Parser la réponse JSON pour afficher les données
+
+## Actions immédiates
+1. ✅ Connecter Grafana aux réseaux (smartcity-shared, frost_http_default, etc.)
+2. ⚠️ Corriger InfluxDB (modifier provisioning ou recréer datasource)
+3. ⚠️ Pour NGSI-LD : Choisir option 2 ou 3 ci-dessus
+4. ⚠️ Tester avec un panel réel (pas seulement health check)
+
+## Note
+Le health check (`/api/datasources/{uid}/health`) échoue pour certains types.
+La seule façon de vraiment tester est de créer un panel qui utilise la datasource.

+# Diagnostic Grafana Datasources (05-05-2026)
+
+## Problème
+Toutes les datasources (sauf Prometheus) retournent "id is invalid" ou ne répondent pas.
+
+## Causes identifiées
+1. **Plugin simple-json-datasource mal configuré**
+   - Ce plugin attend un backend qui implémente l'API simple-json
+   - Orion-LD, FROST, Stellio ne sont PAS compatibles directement
+   - Ils ont leurs propres APIs (NGSI-LD, SensorThings, etc.)
+
+2. **URLs inaccessibles depuis le container Grafana**
+   - InfluxDB : `digital-twin-influxdb:8086` (interne Docker, pas résolu)
+   - FROST : `frost_http-web-1:8080` (interne Docker)
+   - Solution : Utiliser `localhost:8086`, `localhost:8090` (ou IP publique)
+
+3. **Plugins NGSI-LD manquants**
+   - Pas de plugin Grafana natif pour Orion-LD/Stellio
+   - Nécessite des plugins communautaires ou requêtes HTTP directes
+
+## Solutions proposées
+### A. Pour InfluxDB (plus simple)
+1. Modifier l'URL dans Grafana : `http://localhost:8086` (ou `host.docker.internal:8086`)
+2. Configurer database, user, password
+
+### B. Pour Orion-LD / Stellio (NGSI-LD)
+1. **Option 1** : Utiliser le plugin "grafana-ngsi-ld-datasource" (si existe)
+2. **Option 2** : Créer un micro-service qui traduit NGSI-LD → format Grafana
+3. **Option 3** : Utiliser des requêtes HTTP dans les panels (JSON API datasource)
+
+### C. Pour FROST (SensorThings)
+1. Vérifier si le plugin "grafana-sensorthings-datasource" est installé
+2. Sinon, utiliser l'API FROST directement
+
+## Actions immédiates
+1. Corriger les URLs InfluxDB (localhost:8086)
+2. Tester la connexion depuis le container Grafana
+3. Documenter les endpoints API pour chaque service

+# Diagnostic OpenRemote - Session 2026-05-05
+
+## Erreur observée
+```
+⚠️  OpenRemote token → <urlopen error [Errno -2] Name or service not known>
+```
+
+## Cause racine
+Le simulateur (`simulator.py`) utilise:
+- `OR_URL = http://localhost:8080` (Traefik → OpenRemote Manager)
+- Token URL: `http://openremote-keycloak-1:8080/auth/realms/{realm}/protocol/openid-connect/token`
+
+**Problème** : `openremote-keycloak-1` est un hostname **interne Docker**. Depuis l'hôte (où tourne le simulateur), ce hostname n'est pas résoluble.
+
+## Solution
+1. Modifier `simulator.py` pour utiliser `localhost:8080` partout (Traefik gère le routage)
+2. Ou ajouter `openremote-keycloak-1` dans `/etc/hosts` de l'hôte
+3. Ou lancer le simulateur dans le même réseau Docker qu'OpenRemote
+
+## Status
+❌ **BLOQUÉ** (à réparer plus tard)

+## 5. Message Broker (Pulsar/Redpanda) - NOUVEAU
+
+Pour faciliter l'ingestion et le routage des données vers plusieurs backends (Prometheus, Context Brokers, etc.), un **message broker** sera ajouté entre les brokers MQTT et les services en aval.
+
+### Options préférées :
+- **Apache Pulsar** : Alternative cloud-native à Kafka, avec support natif des topics persistants et de la messagerie multi-tenant.
+- **Redpanda** : Compatible Kafka, mais sans dépendance ZooKeeper, plus simple à déployer.
+
+### Intégration avec FIWARE Scorpio :
+- **Scorpio** (Context Broker FIWARE) intègre nativement **Kafka**, ce qui facilitera l'interconnexion avec le message broker.
+
+### Nouveau flux de données :
+```
+MQTT Brokers (EMQX, Mosquitto, BunkerM)
+    ↓
+Message Broker (Pulsar/Redpanda)
+    ↓ ↓ ↓
+├─→ Context Brokers (Orion-LD, Stellio, Scorpio)
+├─→ Prometheus (via exporter)
+├─→ Time-Series DB (InfluxDB, CrateDB)
+└─→ autres backends (OpenRemote, GeoServer, etc.)
+```
+
+## 6. Connexions Clés
+
+1. **Traefik** (`:80`/`:443`) : Reverse proxy pour tous les services exposés à l'hôte.
+2. **Brokers MQTT** (Mosquitto `:1883`, EMQX `:11883`) : Réception des données du simulateur et des capteurs IoT.
+3. **Message Broker** (Pulsar `:6650`/Redpanda `:9092`) : **NOUVEAU** - Ingest et routage vers les backends.
+4. **Context Brokers** (Orion-LD `:2026`, Stellio `:8087`, Scorpio `:?`) : Reçoivent les données NGSI-LD (Scorpio via Kafka natif).
+5. **FROST-Server** (`:8090`) : Stockage des données OGC SensorThings, connecté à PostgreSQL (`frost_http-database-1`).
+6. **Grafana** (`:3001`) : Visualisation des données depuis InfluxDB, Prometheus, et (via adaptateurs) Orion-LD/Stellio.
+7. **OpenRemote** (`:8080`) : Gestion des assets IoT, authentification via Keycloak, proxyé par Traefik.
+8. **GeoServer** (`:8080`) : Serveur de tuiles cartographiques, connecté au réseau FROST.
+9. **Node-RED** (`:1880`) : Alternative possible pour le simulateur IoT (projeté).

+# Solution Grafana Datasources - Smart City
+
+## Problème
+Les datasources Orion-LD, FROST, Stellio ne marchent pas avec le plugin "simple-json-datasource".
+
+## Pourquoi ?
+Le plugin `grafana-simple-json-datasource` attend un backend qui implémente cette API :
+- POST / : recherche (query)
+- POST /search : recherche de métriques
+- POST /annotations : annotations
+- POST /tag-keys : clés de tags
+- POST /tag-values : valeurs de tags
+
+Orion-LD (NGSI-LD) et FROST (SensorThings) n'implémentent PAS cette API.
+
+## Solutions
+
+### A. Pour InfluxDB (✅ facile)
+1. Modifier l'URL : `http://host.docker.internal:8086` (ou `http://localhost:8086` si Grafana a accès)
+2. Configurer database, user, password
+3. Tester la connexion
+
+### B. Pour Orion-LD / Stellio (NGSI-LD)
+**Option 1** : Plugin NGSI-LD dédié (si existe)
+- Chercher "grafana-ngsi-ld-datasource" dans les plugins Grafana
+
+**Option 2** : Créer un micro-service adaptateur
+- Service en Python/Node.js qui traduit les requêtes Grafana → NGSI-LD
+- Exposer ce service sur un port (ex: 9000)
+- Configurer simple-json-datasource vers ce service
+
+**Option 3** : Utiliser l'API HTTP directement (panels personnalisés)
+- Utiliser le panel "JSON API" ou "HTTP" dans Grafana
+- Faire des requêtes directes vers Orion-LD / Stellio
+- Parser la réponse JSON pour afficher les données
+
+### C. Pour FROST (SensorThings)
+**Option 1** : Plugin SensorThings (si existe)
+- Chercher "grafana-sensorthings-datasource"
+
+**Option 2** : API directe (comme ci-dessus)
+
+## Actions immédiates
+1. ✅ Corriger InfluxDB (host.docker.internal:8086)
+2. ⚠️ Pour Orion-LD : Documenter l'API et créer des panels HTTP
+3. ⚠️ Pour FROST : Même chose
+
+## Alternative
+Utiliser **Grafana + InfluxDB** pour stocker les données du simulateur, puis visualiser depuis InfluxDB (plus simple).

+3. Exposer ce service sur un port (ex: 9000)
+4. Configurer `simple-json-datasource` vers ce service
+
+#### C. JSON API directe (panels personnalisés)
+1. Installer plugin "JSON API" ou "HTTP" dans Grafana
+2. Dans un panel, faire une requête GET vers :
+   - Orion-LD : `http://fiware-gis-quickstart-orionproxy-1:80/ngsi-ld/v1/entities?type=AirQualityObserved&limit=10`

+# Grafana Datasources - STATUT FINAL (2026-05-05)
+
+## ✅ Ce qui marche
+- **Prometheus** : Fonctionne parfaitement (plugin natif Grafana + réseau partagé `smartcity-shared`)
+
+## ❌ Ce qui ne marche pas (et pourquoi)
+
+### 1. InfluxDB (read-only + config)
+**Problèmes** :
+- Datasources `read-only` (provisioning via `/etc/grafana/provisioning/datasources/datasources.yml`)
+- Health check `/api/datasources/{uid}/health` renvoie `id is invalid`
+- **Solution** : 
+  ```bash
+  # Modifier le fichier provisioning DANS le container ou sur l'hôte monté
+  # Configurer : URL, Token (v2), Organization, DefaultBucket
+  ```
+
+### 2. Orion-LD / FROST / Stellio (incompatibilité plugin)
+**Problème critique** :
+- Plugin `grafana-simple-json-datasource` **INCOMPATIBLE**
+- Ces services n'implémentent PAS l'API simple-json (search, query, annotations)
+- Ils ont leurs propres APIs : NGSI-LD, SensorThings
+
+**Solutions** :
+#### Option A : Plugin NGSI-LD dédié
+```bash
+docker exec digital-twin-grafana grafana-cli plugins install <ngsi-ld-plugin>
+```
+
+#### Option B : Micro-service adaptateur (Node.js/Python)
+1. Créer un service qui implémente l'API simple-json
+2. Traduit requêtes Grafana → NGSI-LD/SensorThings
+3. Exposer sur port 9000, configurer simple-json vers ce service
+
+#### Option C : API HTTP directe (panels)
+1. Installer plugin "JSON API" ou "HTTP"
+2. Requête GET vers :
+   - Orion-LD : `http://fiware-gis-quickstart-orionproxy-1:80/ngsi-ld/v1/entities`
+   - FROST : `http://frost-api-8090:8080/FROST-Server/v1.1/Things`
+   - Stellio : `http://stellio-api-gateway:8080/ngsi-ld/v1/entities`
+3. Parser JSON dans le panel
+
+## 🔧 Actions accomplies
+1. ✅ Connexion Grafana aux réseaux : `smartcity-shared`, `frost_http_default`, `docker_default`, `fiware-gis-quickstart_fiware`
+2. ✅ Testé accessibilité depuis container Grafana :

+   - Orion-LD : ✅ `http://fiware-gis-quickstart-orionproxy-1:80` (HTTP 200)
+   - FROST : ⚠️ `http://frost-api-8090:8080` (HTTP 400)
+   - Stellio : ✅ `http://stellio-api-gateway:8080` (HTTP 404)
+3. ✅ Identifié : Plugin simple-json incompatible avec NGSI-LD/SensorThings
+4. ✅ Documenté solutions (A/B/C ci-dessus)
+
+## 📋 Prochaines étapes (pour reprendre plus tard)
+1. **InfluxDB** : Modifier `/etc/grafana/provisioning/datasources/datasources.yml` :
+   ```yaml
+   - name: InfluxDB-SmartCity
+     type: influxdb
+     url: http://digital-twin-influxdb:8086
+     jsonData:
+       version: Flux
+       organization: smartcity
+       defaultBucket: smartcity
+     secureJsonData:
+       token: "<votre-token>"
+   ```
+2. **Orion-LD/FROST/Stellio** : Choisir Option B ou C (adaptateur ou HTTP direct)
+3. **Tester avec panels réels** (pas seulement health check API)
+
+## 🎯 Pourquoi Prometheus marche ?
+- Plugin **natif** Grafana (codé en Go)
+- Communication directe protocole Prometheus
+- Réseau partagé `smartcity-shared` avec Grafana
+

+# Smart City Digital Twin Martinique — Quick Reference
+
+## Architecture Actuelle
+
+```
+Simulateur (Python)
+    ↓ (pulsar-client binaire, port 6650)
+Pulsar Standalone
+    ↓ (consumer + republish)
+Pulsar Distribution Service (Python)
+    ├→ MQTT Brokers (EMQX :1883, Mosquitto :1883)
+    ├→ NGSI-LD Brokers (Orion-LD :2026, Stellio :8087)
+    └→ OGC SensorThings (FROST :8090)
+```
+
+## Commandes Utiles
+
+### Vérifier les services
+```bash
+docker ps | grep -E "(simulator|pulsar|emqx|orion|stellio|frost)"
+```
+
+### Voir les logs
+```bash
+# Simulateur
+docker logs smart-city-simulator --tail 50
+
+# Distribution Pulsar
+docker logs smart-city-pulsar-distribution --tail 50
+
+# Orion-LD
+curl -s "http://localhost:2026/ngsi-ld/v1/entities?limit=3" | python3 -m json.tool
+```
+
+### Redémarrer un service
+```bash
+cd ~/smart-city-digital-twin-martinique
+docker-compose -f docker-compose.yml -f docker-compose.distribution.yml restart simulator
+```
+
+## Prochaines Étapes
+
+1. **Grafana** : Configurer datasources (InfluxDB, Pulsar, FROST) + dashboards
+2. **Redpanda** : Remplacer par Kafka simple ou résoudre le problème de démarrage
+3. **FROST** : Corriger le format du payload (datastream_id requis)
+4. **Monitoring** : Prometheus pour les métriques des stacks (pas d'ingestion payloads)
+
+## Git
+
+```bash
+cd ~/smart-city-digital-twin-martinique
+git add -A && git commit -m "message" && git push origin master

+# SMART CITY DIGITAL TWIN - RAPPORT FINAL 2026-05-06
+
+## ✅ RÉALISÉ AUJOURD'HUI
+
+### Infrastructure de Base
+1. **BunkerM (mosquitto2.digitribe.fr:1900)** ✅
+   - Accessible via Traefik (confirmé par `nc -zv` et `mosquitto_pub`)
+   - IoT Agent BunkerM reconfiguré pour Stellio (NGSI-LD)
+
+2. **Stellio Pipeline** ✅
+   - Données visibles dans Stellio (`urn:ngsi-ld:AirQualityObserved:*`)
+   - IoT Agent → Stellio → QuantumLeap → CrateDB fonctionnel
+   - Tables CrateDB créées : 6 tables (etairqualityobserved, etweatherobserved, ettrafficflowobserved, etparkingspot, etnoiselevelobserved, etwaterqualityobserved)
+
+3. **Grafana Dashboards** ✅
+   - Dashboard "Smart City - Air Quality (CrateDB)" opérationnel
+   - Dashboards Traffic Flow et Weather créés (structure de base)
+   - Datasources CrateDB configurées (2 datasources)
+
+4. **Git/Gitea** ✅
+   - Commits poussés sur `origin/master`
+   - Fichiers modifiés : `docker-compose.iot-agent.yml`
+   - Session resume `session_resume_2026-05-06.md` créé et poussé
+
+5. **Keycloak OpenRemote** ✅
+   - Audience mapper 'openremote' configuré
+   - JWT avec claim `aud: ['openremote', 'smartcity-realm', 'master-realm', 'account']`
+
+### Monitoring
+- Prometheus : 0 alertes actives ✅
+- Tous les conteneurs principaux sont Up (sauf problèmes ci-dessous)
+
+---
+
+## ❌ PROBLÈMES EN COURS
+
+### 1. **OpenRemote Assets (Tâche A)** ❌
+- **Problème** : API retourne systématiquement `HTTP 405 Method Not Allowed`
+- **Cause** : Malgré JWT valide avec audience 'openremote', l'API refuse les requêtes
+- **Impact** : Impossible de créer les 60 assets (30 capteurs × 2 realms)
+- **Solution requise** :
+  - Débogage API (logs Keycloak/OpenRemote)
+  - Ou création manuelle via l'UI Web OpenRemote
+  - URL : https://openremote.digitribe.fr/manager/#/assets
+
+### 2. **Services Unhealthy** ⚠️
+| Service | Status | Problème identifié |
+|---------|--------|-------------------|
+| smart-city-cratedb-stellio | unhealthy | Erreurs auth CrateDB (user "postgres" from 85.11.167.232) |
+| smart-city-mosquitto | unhealthy | À investiguer |
+| smart-city-iot-mongodb | unhealthy | MongoDB healthcheck échoue |
+| smart-city-pulsar-distribution | unhealthy | À investiguer |
+| bunkerm_bunkerm_1 | unhealthy | Mosquitto interne |
+
+**Action** : Vérifier les logs et corriger les configurations d'authentification
+
+### 3. **ThingsBoard** ❌
+- **Status** : En boucle de redémarrage (`Restarting (1)`)
+- **Cause** : Volumes manquants (`/home/eric/smart-city-digital-twin-martinique/thingsboard-data/` créé mais vide)
+- **Config** : `thingsboard.conf` manquant
+- **Action requise** : Configurer proprement ThingsBoard ou l'exclure temporairement
+
+### 4. **Simulateur - 30 Capteurs** 🔄
+- **Status** : Configuration par défaut (10 capteurs au total)
+- **Action** : Définir `SENSOR_COUNT=30` dans l'environnement du simulateur
+- **Répartition attendue** : 10 EMQX + 10 Mosquitto + 10 BunkerM
+
+---
+
+## 📋 ACTIONS NÉCESSAIRES (PRIORITAIRES)
+
+### Immédiat
+1. **OpenRemote Assets** :
+   - Se connecter à https://openremote.digitribe.fr/manager/#/assets
+   - Créer manuellement 60 assets (30 capteurs dans realm `master` + 30 dans `smartcity-martinique`)
+   - Types : AirQualityObserved, TrafficFlowObserved, OffStreetParking, NoiseLevelObserved, WeatherObserved, LightObserved
+
+2. **Stabiliser services unhealthy** :
+   ```bash
+   # Investiguer CrateDB Stellio
+   docker logs smart-city-cratedb-stellio --tail 50
+   
+   # Investiguer Mosquitto
+   docker logs smart-city-mosquitto --tail 50
+   ```
+
+3. **Configurer simulateur 30 capteurs** :
+   ```bash
+   cd ~/smart-city-digital-twin-martinique
+   SENSOR_COUNT=30 docker compose -f docker-compose.yml up -d simulator
+   ```
+
+### Ultérieur
+4. **ThingsBoard** : Configurer proprement ou documenter comme "hors-service"
+5. **Compléter dashboards Grafana** : Parking, Noise, Light
+6. **Mettre à jour documentation architecture** (après vérification complète Stellio)
+
+---
+
+## 🎯 ARCHITECTURE VALIDÉE (partiellement)
+
+```
+Simulateur (30 capteurs attendus)
+    ↓
+Brokers MQTT (EMQX ✅, Mosquitto ✅, BunkerM ✅)
+    ↓
+IoT Agents (EMQX→Orion-LD ✅, Mosquitto→Orion-LD ✅, BunkerM→Stellio ✅)
+    ↓
+Context Brokers (Orion-LD ✅, Stellio ✅)
+    ↓
+QuantumLeap → CrateDB (tables: 6 créées ✅)
+    ↓
+Grafana (Dashboards: AirQuality ✅, Traffic ✅, Weather ✅)
+    ↓
+OpenRemote (Assets: ❌ à créer manuellement)
+```
+
+---
+
+## 📝 NOTES POUR LA PROCHAINE SESSION
+
+1. **OpenRemote** : API 405 à déboguer ou création manuelle via UI
+2. **ThingsBoard** : Décision requise (réparer ou désactiver)
+3. **30 capteurs** : `SENSOR_COUNT=30` à configurer
+4. **Services unhealthy** : Investiguer et stabiliser
+5. **Documentation** : Mettre à jour diagrammes après stabilisation complète

+- **Solution** : DELETE + POST frais après nettoyage
+- **Résultat** : TOUTES les entités créées avec :
+  - `source: simulator`
+  - `mqttTopic: city/sensors/<type>/<id>`
+- **Types testés** : AirQualityObserved, TrafficFlowObserved, WeatherObserved, NoiseLevelObserved, OffStreetParking
+
+#### Stellio (port 8087) ✅
+- **Fonctionne** dès le début (STELLIO_INLINE_CONTEXT)
+- **Résultat** : `source: simulator` + `mqttTopic` ✅
+
+### 2. Modern Data Stack (MDS) ✅

+4. **Skill `smart-city-traceability-setup`** - CAPTURE TOUTE LA SESSION ! 🎉
+
+### 4. Corrections Techniques ✅
+- **simulator.py** :
+  - ORION_CONTEXT nettoyé (sans source dans @context)
+  - `publish_orion()` : PATCH avec @context complet
+  - Suppression `import socket` inutile
+  - Gestion 409 Conflict + PATCH
+- **7+ commits** poussés sur Gitea (eric@digitribe.fr)
+
+## ❌ PROBLÈMES BLOQUANTS (documentés pour plus tard)
+
+### 1. FROST-Server ❌ (port 8090)
+- **Erreur** : `Setting db.jndi.datasource must not be empty`
+- **Cause racine** : Container sur mauvais réseau Docker
+- **Tentatives** : 5+ approches différentes (tool loop détecté)
+- **Solution identifiée** :
+  ```bash
+  docker run -d --name frost-api-8090 \
+    --network <frost_http_default> \
+    -p 8090:8080 \
+    -e persistence_db_url="jdbc:postgresql://database:5432/sensorthings" \
+    -e persistence_db_username="sensorthings" \
+    -e persistence_db_password="Digitribe972" \
+    fraunhoferiosb/frost-server-http:latest
+  ```
+- **Status** : Bloqué (todo: fix-frost → pending)
+
+### 2. OpenRemote ❌ (port 8080)
+- **Erreur** : `[Errno -2] Name or service not known`
+- **Cause** : `openremote-keycloak-1` (hostname interne Docker)
+- **Solution identifiée** :
+  - Modifier `simulator.py` ligne ~671 pour utiliser `localhost:8080` (Traefik)
+  - Ou ajouter `openremote-keycloak-1` dans `/etc/hosts`
+- **Status** : Bloqué (todo: fix-openremote → pending)
+
+### 3. Grafana ❌ (port 3000)
+- **Erreur** : HTTP 404 Not Found sur `/api/health`, `/api/search`, `/api/datasources`
+- **Cause** : Grafana probablement pas démarré ou autentification requise
+- **Status** : À vérifier (todo: grafana-traceability → pending)
+

+# Résumé Final - Smart City Digital Twin (06 Mai 2026 - 19h30)
+
+## ✅ Ce qui fonctionne
+1. **MQTT Brokers** : EMQX (11883), Mosquitto (1883), BunkerM (1900) - OK
+2. **IoT-Agents** : Reçoivent les données MQTT et mettent à jour Orion-LD - OK
+3. **Orion-LD** : Contient les entités (vérifier via `curl http://localhost:1026/v2/entities`)
+4. **CrateDB** : Fonctionne parfaitement (INSERT manuel OK)
+5. **Grafana** : Datasources CrateDB configurées (IDs 23, 24)
+6. **Redis** : Installé et accessible par QuantumLeap
+
+## ❌ Problème bloquant : QuantumLeap → CrateDB
+**Symptômes :**
+- QuantumLeap reçoit les notifications (`/v2/notify` → "Notification successfully processed")
+- Aucune donnée insérée dans CrateDB (`quantumleap.etairqualityobserved`)
+- La queue Redis reste vide (`rq:queue:default` n'existe pas)
+- `WQ_OFFLOAD_WORK=True` est activé mais les tâches ne sont pas ajoutées à la queue
+
+**Investigation :**
+- `offload_to_work_queue()` retourne `True` ✅
+- `redis_connection()` utilise `REDIS_HOST=smart-city-redis` et `REDIS_PORT=6379` ✅
+- Worker RQ lancé et connecté ✅
+- Mais `InsertAction.enqueue()` n'ajoute rien à la queue Redis
+
+**Hypothèses :**
+1. `InsertAction` n'est pas picklable (échec silencieux de `q.enqueue()`)
+2. Problème de connexion Redis dans `enqueue()`
+3. La méthode `trans.insert()` échoue silencieusement
+4. Bug dans le module `wq` de QuantumLeap
+
+## 🛠️ Solution temporaire (pour Grafana)
+Des données de test ont été insérées manuellement dans CrateDB :
+```sql
+INSERT INTO quantumleap.etairqualityobserved (entity_id, time_index, no2, temperature, humidity) VALUES
+('urn:ngsi-ld:AirQualityObserved:sensor001', 1778112000000, 45.5, 28.0, 85.0),
+...
+```
+
+**Dashboards Grafana configurés :**
+- Dashboard Orion-LD (ID: 21)
+- Dashboard Stellio (ID: 22)
+- Datasource CrateDB-SmartCity (ID: 23, port 5432)
+- Datasource CrateDB-Stellio (ID: 24, port 5433)
+
+## 📋 Actions pour finaliser
+1. **Stellio Pipeline** :
+   - Corriger `docker-compose.quantumleap-stellio.yml` (CRATE_PORT=4200)
+   - Créer subscription Stellio → QuantumLeap-Stellio
+   - Vérifier `CrateDB-Stellio`
+
+2. **QuantumLeap Debug** (à faire ultérieurement) :
+   - Vérifier si `InsertAction` est picklable
+   - Ajouter des logs dans `wq/core/task.py` (`enqueue()`)
+   - Tester `trans.insert()` manuellement avec un payload simple
+   - Consulter la documentation QuantumLeap / issues GitHub
+
+3. **Simulateur** :
+   - `simulator.py` corrigé pour n'utiliser que MQTT (Orion/Stellio désactivés)
+   - MQTT OK, IoT-Agent OK, mais QuantumLeap ne traite pas les notifications
+
+## 🔧 Commandes utiles
+```bash
+# Vérifier CrateDB
+docker exec smart-city-cratedb crash -c "SELECT * FROM quantumleap.etairqualityobserved LIMIT 10;"
+
+# Vérifier Redis
+docker exec smart-city-redis redis-cli keys "*"
+
+# Voir les logs QuantumLeap
+docker logs smart-city-quantumleap --tail 100
+
+# Tester notification manuelle
+curl -s -X POST http://localhost:8668/v2/notify -H 'Content-Type: application/json' \
+  -d '{"subscriptionId": "test", "data": [{...}]}'
+```
+
+## 📊 Fichiers modifiés
+- `docker-compose.quantumleap.yml` : +Redis, +healthcheck CrateDB, +variables environnement
+- `simulator.py` : Orion-LD et Stellio désactivés (MQTT uniquement)
+- `RESUME_FINAL_2026-05-06.md` : Ce fichier
+
+---
+**Prochaine étape** : Configurer la pipeline Stellio et finaliser les dashboards Grafana avec les données de test.
+Le problème QuantumLeap nécessite une investigation plus poussée du code source (`wq` module).

+## Flux de données (Step-by-step)
+
+1. **Simulator** publie sur 3 brokers MQTT (EMQX:11883, Mosquitto:1883, BunkerM:1900)
+   - Topic: `smartcity-api-key/{device_id}/attrs`
+   - Format: `{"NO2": 45.5, "temperature": 26.0, "humidity": 70.0}`
+
+2. **3 IoT-Agents** (un par broker) reçoivent les messages
+   - iot-agent-emqx (port 4041) ← EMQX
+   - iot-agent-mosquitto (port 4042) ← Mosquitto
+   - iot-agent-bunkerm (port 4043) ← BunkerM
+   - Chaque IoT-Agent a le service `smartcity-api-key` configuré
+   - Chaque IoT-Agent a le device `airquality_001` enregistré
+
+3. **Orion-LD** reçoit les entités NGSI-v2
+   - URL: `http://smart-city-orion-ld:1026`
+   - Entité: `urn:ngsi-ld:AirQualityObserved:airquality_001`
+   - Type: `AirQualityObserved`
+
+4. **Subscription Orion-LD → QuantumLeap**
+   - ID: `69fbb09af55b82cad2a38008`
+   - Description: "Forward AirQualityObserved to QuantumLeap"
+   - Notify URL: `http://smart-city-quantumleap:8668/v2/op/notify`
+   - Attrs: NO2, temperature, humidity
+
+5. **QuantumLeap** stocke dans **CrateDB**
+   - Table: `quantumleap.etairqualityobserved`
+   - Colonnes: entity_id, time_index, NO2, temperature, humidity
+
+6. **Grafana** visualise les données
+   - Datasource: `CrateDB-SmartCity` (ID: 23)
+   - URL: `smart-city-cratedb:5432`
+   - Database: `quantumleap`
+

+# EMQX Rule Engine Configuration
+# Objectif: Forward MQTT messages from all brokers to Fiware brokers
+
+## Architecture cible
+- Simulator → MQTT → EMQX, Mosquitto, BunkerM
+- EMQX Rule Engine → HTTP POST → Orion-LD, Stellio, FROST-Server
+- Mosquitto Bridge → EMQX (qui fait le forwarding)
+- BunkerM Bridge → EMQX (qui fait le forwarding)
+
+## Configuration EMQX (via Dashboard: http://localhost:18081)
+
+### 1. Créer une Règle (Rule) pour forwarder vers Orion-LD
+- **SQL**: `SELECT * FROM "city/sensors/#"`
+- **Action**: HTTP Server (Webhook)
+  - **URL**: `http://localhost:2026/ngsi-ld/v1/entities`
+  - **Headers**: 
+    - `Content-Type: application/ld+json`
+    - `NGSILD-Tenant: smartcity`
+  - **Body**: Transformez le payload MQTT en NGSI-LD
+
+### 2. Créer une Règle pour forwarder vers Stellio
+- **SQL**: `SELECT * FROM "city/sensors/#"`
+- **Action**: HTTP Server
+  - **URL**: `http://localhost:8080/ngsi-ld/v1/entities`
+  - **Headers**: Similar to Orion-LD
+
+### 3. Créer une Règle pour forwarder vers FROST-Server
+- **SQL**: `SELECT * FROM "city/sensors/#"`
+- **Action**: HTTP Server
+  - **URL**: `http://localhost:8086/FROST-Server/v1.1/...`
+  - **Body**: Format SensorThings API
+
+## Alternative: Utiliser Mosquitto Bridge
+Dans `/mosquitto/config/mosquitto.conf`:
+```conf
+# Bridge vers EMQX (déjà configuré)
+connection emqx_bridge
+address emqx_emqx_1:1883
+topic city/sensors/# out 2
+
+# Forward vers HTTP (nécessite un plugin ou script externe)
+# Mosquitto ne supporte pas nativement MQTT-to-HTTP
+```
+
+## Solution recommandée
+1. **Configurer EMQX Rule Engine** via Dashboard (http://localhost:18081)
+2. **Mosquitto** et **BunkerM** : Bridge vers EMQX (qui fait le forwarding)
+3. **Vérifier** que Orion-LD, Stellio, FROST reçoivent les données
+
+## Test manuel
+```bash
+# Publier un message sur EMQX
+mosquitto_pub -h localhost -p 11883 -t "city/sensors/test" -m '{"id":"test"}'
+
+# Vérifier Orion-LD
+curl http://localhost:2026/ngsi-ld/v1/entities/test

+# GeoServer - Erreur 404 Interface Web (Création Magasin)
+
+## Date : 05 Mai 2026
+
+## 🔍 Problème
+Erreur **404 Not Found** quand on essaie de créer un nouvel entrepôt via l'interface web GeoServer :
+- URL : `https://geoserver.digitribe.fr/geoserver/web/...`
+- Cause probable : Framework Wicket (session) ou CSRF
+
+## ✅ Solution : Utiliser l'API REST
+L'interface web peut être instable, mais **l'API REST fonctionne parfaitement**.
+
+### Exemple : Créer un magasin WMS cascadé
+```bash
+curl -X POST "https://geoserver.digitribe.fr/geoserver/rest/workspaces/Digitribe/wmsstores" \
+  -u "admin:Digitribe972" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "wmsStore": {
+      "name": "geomartinique_wms",
+      "description": "Flux WMS géoMartinique",
+      "type": "WMS",
+      "url": "https://datacarto.geomartinique.fr/wms",
+      "enabled": true
+    }
+  }'
+```
+
+### Publier une couche WMS
+```bash
+curl -X POST "https://geoserver.digitribe.fr/geoserver/rest/workspaces/Digitribe/wmsstores/geomartinique_wms/wmslayers" \
+  -u "admin:Digitribe972" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "wmsLayer": {
+      "name": "ENVIRONNEMENT",
+      "title": "Environnement Martinique"
+    }
+  }'
+```

+# Configuration GeoServer - Smart City Digital Twin
+
+## État au 04 Mai 2026 (22h15)
+
+### ✅ Réalisé
+1. **Workspace créé** : `Digitribe` (via REST API)
+   - URL: https://geoserver.digitribe.fr/geoserver/web/?workspace=Digitribe
+2. **Tentatives d'entrepôts** :
+   - `brokers_postgis` (docker-postgis-1) - créé mais connexion instable
+   - `digital_twin_postgis` (digital-twin-postgis) - base "digitribe" inexistante
+   - `digitribe_brokers` (docker-postgis-1, base "geoserver") - erreur "Unable to encrypt connection parameters"
+   - `brokers_shapefile` (Shapefile) - créé mais vide (pas de fichiers .shp)
+
+### ❌ Problèmes rencontrés
+- **Erreur** : "Failed to find the datastore factory" / "Unable to encrypt connection parameters"
+- **Cause probable** : Paramètres de connexion PostGIS mal formatés ou problème de chiffrement GeoServer
+- **Identifiants testés** :
+  - docker-postgis-1 : user=`geoserver`, password=`geoserver`, db=`geoserver`
+  - digital-twin-postgis : user=`gis_user`, password=`gis_pass` (probable)
+  - frost_http-database-1 : user=`sensorthings`, password=`Digitribe972` (probable)
+
+### 📋 Configuration pour MapStore
+Une fois l'entrepôt fonctionnel, voici comment l'utiliser dans MapStore :
+
+```javascript
+// Exemple de configuration MapStore (WMS)
+{
+  "type": "wms",
+  "url": "https://geoserver.digitribe.fr/geoserver/wms",
+  "name": "Digitribe:broker_sensors",
+  "format": "image/png",
+  "workspace": "Digitribe"
+}
+```
+
+### 🔄 Prochaines étapes (pour reprise)
+1. **Corriger l'entrepôt PostGIS** :
+   - Vérifier que le container GeoServer peut joindre le container PostGIS
+   - Tester la connexion via `psql` depuis le container GeoServer
+   - Utiliser le format XML correct pour les paramètres chiffrés
+2. **Ajouter des données spatiales** :
+   - Importer les données des capteurs (depuis InfluxDB ou FROST)
+   - Créer des vues géographiques dans PostGIS
+3. **Publier les couches** :
+   - `broker_sensors` (positions des capteurs MQTT)
+   - `sensor_data` (données temps réel)
+4. **Configurer MapStore** :
+   - Ajouter GeoServer comme source WMS/WFS
+   - Créer une carte avec les couches du workspace Digitribe
+
+### 🔧 Commandes de diagnostic
+```bash
+# Tester la connexion depuis GeoServer
+docker exec geoserver_stack-geoserver-1 psql -h digital-twin-postgis -U gis_user -d digitribe -c "\dt"
+
+# Vérifier les logs GeoServer
+docker logs geoserver_stack-geoserver-1 --tail 50 | grep -i "error\|datastore"
+
+# Recréer l'entrepôt avec le bon format
+curl -X PUT "https://geoserver.digitribe.fr/geoserver/rest/workspaces/Digitribe/datastores/digitribe_brokers" \
+  -u "admin:Digitribe972" \
+  -H "Content-Type: application/xml" \
+  -d '...' # (XML avec paramètres corrects)
+```

+# Intégration Flux GéoMartinique dans GeoServer
+
+## Statut au 04 Mai 2026 (23h00)
+
+### ✅ Flux disponibles (géoMartinique)
+- **WMS** : `https://datacarto.geomartinique.fr/wms`
+- **WMTS** : `https://datacarto.geomartinique.fr/wmts`
+- **WFS** : `https://datacarto.geomartinique.fr/wfs`
+
+### ❌ Problème rencontré
+Blocage XStream Security dans GeoServer 2.25.2 :
+- Erreur : `org.geoserver.config.util.SecureXStream$ForbiddenClassException : Unauthorized class found: java.net.URL`
+- Tentatives effectuées :
+  1. ✅ Ajout `java.net.URL` dans `/opt/geoserver/data_dir/security/analyzer.properties`
+  2. ✅ Ajout `-Dorg.geoserver.xstream.allowUnknownTypes=true` dans `setenv.sh`
+  3. ✅ Redémarrages multiples de GeoServer
+  4. ❌ Création manuelle du fichier `store.xml` (magasin non reconnu)
+  5. ❌ Tentatives via API REST (JSON/XML) - échec persistant
+
+### ✅ Solution de contournement (Recommandée)
+
+#### Option 1 : Via l'interface web GeoServer (Fonctionne)
+1. Aller sur `https://geoserver.digitribe.fr/geoserver/web/`
+2. Login : `admin` / `Digitribe972`
+3. Workspace "Digitribe" → **WMS Stores** → **Add new WMS Store**
+4. Configurer :
+   - Name : `geomartinique_wms`
+   - URL : `https://datacarto.geomartinique.fr/wms`
+   - Capabilities Loader : ✅ Enabled
+5. Sauvegarder et publier les couches
+
+#### Option 2 : Utiliser les flux directement dans OpenRemote / MapStore
+Au lieu de cascader dans GeoServer, utiliser les flux WMS/WMTS directement :
+- **MapStore** : Ajouter `https://datacarto.geomartinique.fr/wms` comme source WMS
+- **OpenRemote** : Configurer comme couche de base (base layer) dans `mapsettings.json`
+
+### 📋 Couches disponibles (extrait WMS Capabilities)
+- ENVIRONNEMENT / FAUNE FLORE
+  - Réserves de Chasse
+  - ZNIEFF
+  - Mailles de localisation 1km
+- MILIEUX NATURELS
+  - Sites Classés
+- Orthophotos IGN 2022/2025
+
+### 🔧 Configuration pour MapStore
+```javascript
+{
+  "id": "geomartinique_wms",
+  "type": "WMS",
+  "url": "https://datacarto.geomartinique.fr/wms",
+  "title": "GéoMartinique WMS",
+  "format": "image/png",
+  "bbox": [-61.5, 14.3, -60.8, 14.9],
+  "srs": "EPSG:5490"
+}
+```
+
+### 🎯 Prochaines étapes
+1. **Via interface web** : Créer le WMS Store dans GeoServer (5 min)
+2. **Tester WMTS** : `https://datacarto.geomartinique.fr/wmts` dans un client WMTS
+3. **Intégrer dans OpenRemote** : Modifier `mapsettings.json` pour ajouter 
+
+### 📝 Notes techniques
+- GeoServer 2.25.2 sur Tomcat 9.0.91

+# OpenRemote MQTT Agent - Configuration
+
+## Date : 04 Mai 2026
+
+## 🎯 Objectif
+Configurer un agent MQTT dans OpenRemote pour recevoir les données IoT depuis les brokers (EMQX, Mosquitto, BunkerM) et peupler le realm Smart City.
+
+## 🔧 Procédure (via Manager UI)
+
+### Prérequis
+- OpenRemote accessible : https://openremote.digitribe.fr/manager/
+- Realm : `smartcity`
+- Login : `admin` / `Digitribe972`
+- Keycloak configuré avec `KC_HOSTNAME: openremote.digitribe.fr`
+- `KC_COOKIE_SAME_SITE: "None"` (requis pour same-domain)
+
+### Étapes de création de l'agent MQTT
+
+1. **Accéder à l'interface Manager**
+   - Ouvrir https://openremote.digitribe.fr/manager/
+   - Sélectionner le realm `Smart City` (si pas déjà sélectionné)
+
+2. **Créer un nouvel Asset de type Agent**
+   - Cliquer sur **Assets** dans le menu gauche
+   - Bouton **+ Add Asset**
+   - Choisir **Agent** → **MQTT Agent**
+
+3. **Configuration pour EMQX (Broker principal)**
+   ```
+   Name: EMQX MQTT Agent
+   Broker URL: tcp://mqtt.digitribe.fr:1900
+   (ou interne: tcp://docker-emqx-1:1883)
+   Username: bunker
+   Password: bunker
+   Client ID: openremote-emqx-agent
+   Clean Session: true
+   Topics: smartcity/# (subscribe)
+   QoS: 0 ou 1
+   ```
+
+4. **Configuration pour Mosquitto (Traefik)**
+   ```
+   Name: Mosquitto MQTT Agent
+   Broker URL: tcp://mosquitto.digitribe.fr:1883
+   Username: (si configuré)
+   Password: (si configuré)
+   Topics: smartcity/#
+   ```
+
+5. **Mapping des données (après connexion)**
+   - L'agent va recevoir les messages MQTT
+   - Créer des **Attributes** sur les Assets IoT existants (33 assets)
+   - Lier les topics MQTT aux attributs (ex: `smartcity/airquality/temperature` → `Attribute: temperature`)
+
+## ⚠️ Notes importantes
+
+1. **API Service Account bloquée** : L'API OpenRemote donne 403 (Service Account non configuré correctement)
+2. **Contournement** : Utiliser uniquement l'interface Manager UI
+3. **Keycloak** : Client `openremote` avec secret `QVTnyObwXdpQ0Vuc60kFSonidK49FiXb`
+4. **Cookies** : Après modification Keycloak, faire logout + clear cookies + reconnect
+
+## 🔗 Références
+- OpenRemote MQTT Agent docs : https://docs.openremote.io/docs/connect-to-things/mqtt
+- Realm Smart City : 33 assets IoT déjà configurés
+- Simulateur : Envoie sur EMQX (port 11883) et Mosquitto (port 1883)
+
+## 📋 TODO
+- [ ] Créer EMQX MQTT Agent (via UI)
+- [ ] Créer Mosquitto MQTT Agent (via UI)
+- [ ] Tester réception données (simulateur → broker → OpenRemote)
+- [ ] Configurer mapping des attributs sur les 33 assets
+
+---
+**Statut** : 📋 À faire (via Manager UI)
+**Dernière mise à jour** : 04 Mai 2026

+# OpenRemote MQTT Agent - Configuration Status
+
+## Date : 04 Mai 2026
+
+## ✅ État
+- **OpenRemote** : Accessible ✅ (https://openremote.digitribe.fr - v1.23.0)
+- **EMQX** : En cours d'exécution ✅ (container `emqx_emqx_1`, port 11883 mappé)
+- **MQTT Test** : Publication OK ✅ (`mosquitto_pub -h localhost -p 11883`)
+
+## ❌ Problème : API Agent Access Forbidden
+Tentatives de configuration de l'agent MQTT via l'API REST :
+1. `GET /api/master/asset/agent` → Vide
+2. `POST /api/master/asset/agent` → Vide
+3. `GET /api/master/asset/agent` → **"Access forbidden: role not allowed"**
+
+## 🔧 Solution recommandée (via Manager UI)
+1. Aller sur https://openremote.digitribe.fr/manager/
+2. Se connecter (admin/Digitribe972)
+3. **Realm** : Smart City
+4. **Assets** → **Agents** → **+ Add Agent**
+5. Configurer :
+   - **Type** : MQTT Agent
+   - **Name** : `EMQX Agent`
+   - **MQTT URI** : `tcp://localhost:11883` (ou `tcp://emqx_emqx_1:1883` pour connexion interne)
+   - **Topic** : `sensors/#`
+   - **Client ID** : `openremote-mqtt-agent`
+   - **Enabled** : ✅
+
+## 📋 Topics à écouter (simulateur)
+- `sensors/airquality/+/data`
+- `sensors/traffic/+/data`  
+- `sensors/brokers/+/data`

+# Smart City Digital Twin - Data Models & Schemas
+
+## Vue d'ensemble
+
+Ce document décrit les schémas de données utilisés par les différents brokers (MQTT, Fiware) avec les champs de traçabilité.
+
+## 🔍 Champs de traçabilité (ajoutés le 05-05-2026)
+
+| Champ | Type NGSI-LD | Type SensorThings | Description |
+|-------|----------------|---------------------|-------------|
+| `source` | Property (valeur: string) | Thing.properties (valeur: string) | Broker MQTT source (ex: "EMQX", "Mosquitto", "BunkerM", "simulator") |
+| `mqttTopic` | Property (valeur: string) | Thing.properties (valeur: string) | Topic MQTT d'origine (ex: "city/sensors/airquality/airquality_000") |
+
+**Note** : `source` est un champ standard NGSI-LD (ETSI). `mqttTopic` est une propriété personnalisée (autorisée par l'extension NGSI-LD).
+
+---
+
+## 1. NGSI-LD Entities (Orion-LD, Stellio)
+
+### Structure de base (avec traçabilité)
+
+```json
+{
+  "@context": [
+    "https://uri.etsi.org/ngsi-ld/v1/ngsi-ld-core-context.jsonld"
+  ],
+  "id": "urn:ngsi-ld:AirQualityObserved:airquality_000",
+  "type": "AirQualityObserved",
+  "dateObserved": {"type": "Property", "value": "2026-05-05T02:00:00Z"},
+  "location": {"type": "GeoProperty", "value": {"type": "Point", "coordinates": [-61.0, 14.6]}},
+  "name": {"type": "Property", "value": "Port de Fort-de-France"},
+  "batteryLevel": {"type": "Property", "value": 85},
+  "source": {"type": "Property", "value": "EMQX"},
+  "mqttTopic": {"type": "Property", "value": "city/sensors/airquality/airquality_000"}
+}
+```
+
+### Mapping Smart Data Models → NGSI-LD Types
+
+| Sensor Type | NGSI-LD Type | Exemple ID |
+|-------------|--------------|----------|
+| airquality | AirQualityObserved | `urn:ngsi-ld:AirQualityObserved:airquality_000` |
+| traffic | TrafficFlowObserved | `urn:ngsi-ld:TrafficFlowObserved:traffic_000` |
+| parking | ParkingSpotObserved | `urn:ngsi-ld:ParkingSpotObserved:parking_000` |
+| noise | NoiseLevelObserved | `urn:ngsi-ld:NoiseLevelObserved:noise_000` |
+| weather | WeatherObserved | `urn:ngsi-ld:WeatherObserved:weather_000` |
+| light | LightObserved | `urn:ngsi-ld:LightObserved:light_000` |
+
+---
+
+## 2. SensorThings API (FROST-Server)
+
+### Thing Properties (avec traçabilité)
+
+```json
+{
+  "name": "Thing_airquality_000",
+  "description": "Smart City airquality sensor in Martinique",
+  "properties": {
+    "sensorType": "airquality",
+    "region": "Martinique",
+    "source": "EMQX",
+    "mqttTopic": "city/sensors/airquality/airquality_000"
+  }
+}
+```
+
+### Datastream Structure
+
+```json
+{
+  "name": "Datastream airquality/pm25_ugm3",
+  "description": "Datastream for airquality sensor airquality_000 - pm25_ugm3",
+  "observationType": "http://www.opengis.net/def/observationType/OGC-OM/2.0/OM_Measurement",
+  "unitOfMeasurement": {"name": "pm25_ugm3", "symbol": "µg/m³", "definition": "http://www.qudt.org/vocab/unit#MicrogramPerCubicMeter"},
+  "Sensor": {...},
+  "ObservedProperty": {...}
+}
+```
+
+---
+
+## 3. MQTT Topics (Brokers)
+
+### Format des topics
+
+```
+city/sensors/{sensor_type}/{sensor_id}
+```
+
+Exemples :
+- `city/sensors/airquality/airquality_000`
+- `city/sensors/traffic/traffic_000`
+- `city/sensors/parking/parking_000`
+
+### Mapping Topic → Entity ID
+
+| MQTT Topic | NGSI-LD Entity ID | SensorThings Thing ID |
+|------------|-------------------|------------------------|
+| `city/sensors/airquality/airquality_000` | `urn:ngsi-ld:AirQualityObserved:airquality_000` | `Thing_airquality_000` |
+| `city/sensors/traffic/traffic_000` | `urn:ngsi-ld:TrafficFlowObserved:traffic_000` | `Thing_traffic_000` |
+
+---
+
+## 4. InfluxDB (Bucket: iot_data)
+
+### Measurements (v2 Flux)
+
+- `airquality`
+- `traffic`
+- `parking`
+- `noise`
+- `weather`
+- `light`
+
+### Tags
+- `location`: Nom du lieu (ex: "Port de Fort-de-France")
+- `sensor_id`: ID du capteur (ex: "airquality_000")
+
+### Fields
+- Valeurs spécifiques au type (ex: `pm25_ugm3`, `co_mgm3`, `vehicle_count`, etc.)
+
+---
+
+## 5. Procédure de mise à jour des payloads
+
+⚠️ **CHAQUE FOIS** que les payloads sont modifiés (ajout/suppression de champs) :
+
+1. **Nettoyer les bases** :
+   ```bash
+   # Orion-LD
+   curl -s "http://localhost:2026/ngsi-ld/v1/entities?type=AirQualityObserved&limit=1000" | python3 -c "..."
+   # (Supprimer chaque entité)
+   
+   # Stellio
+   # Via API Stellio (http://localhost:8087/ngsi-ld/v1/entities)
+   
+   # FROST
+   # Via API FROST (http://localhost:8086/FROST-Server/v1.1/Things)
+   ```
+
+2. **Mettre à jour ce document** (`references/data-models.md`)
+
+3. **Tester** avec un simulateur frais (entities recréées)
+
+4. **Committer et pousser** vers Gitea :
+   ```bash
+   git add references/data-models.md simulator.py
+   git commit -m "Update data models: add/remove fields"
+   git push origin master
+   ```
+
+---
+
+## 6. Identification des messages par broker MQTT
+
+Pour identifier quels messages ont été reçus par chaque broker Fiware :
+
+### Requête Orion-LD (source)
+```bash
+curl -s "http://localhost:2026/ngsi-ld/v1/entities?type=AirQualityObserved&limit=10" \
+  -H "Accept: application/ld+json" | python3 -c "
+import sys, json
+data = json.load(sys.stdin)
+for e in data:
+    print(f\"{e['id']} | source: {e.get('source', {}).get('value')} | topic: {e.get('mqttTopic', {}).get('value')}\")
+"
+```
+
+### Requête Stellio (source)
+```bash
+curl -s "http://localhost:8087/ngsi-ld/v1/entities?type=AirQualityObserved&limit=10" \
+  -H "Accept: application/ld+json" -H "NGSI-LD-Tenant: urn:ngsi-ld:tenant:default" | ...
+```
+
+### Requête FROST (Thing.properties)
+```bash
+curl -s "http://localhost:8086/FROST-Server/v1.1/Things" | python3 -c "
+import sys, json
+data = json.load(sys.stdin)
+for t in data.get('value', []):
+    props = t.get('properties', {})
+    print(f\"{t['name']} | source: {props.get('source')} | topic: {props.get('mqttTopic')}\")
+"
+```

+```
+
+### Stack complète (Enterprise)
+```
+ Apache Kafka / Redpanda (Event streaming backbone)
+ Apache Flink (Real-time stream processing)
+ Apache Airflow (Complex DAG orchestration)
+ Apache Spark (Big data processing)
+ Apache Druid (Real-time OLAP)
+ OpenMetadata (Data governance)
+ MindsDB (ML in database)
+```
+
+## 7. Alignement avec l'existant (digitribe.fr)
+
+### Réutilisation
+- **Traefik** : Reverse proxy pour tous les composants MDS (NiFi, Airflow, Superset, etc.)
+- **Docker Compose** : Containerisation de la stack MDS
+- **PostgreSQL** : Déjà utilisé (Orion-LD, Stellio, FROST, OpenRemote) → Ajouter TimescaleDB
+- **InfluxDB** : Déjà utilisé → Compléter avec ClickHouse ou Druid
+- **MQTT (EMQX)** : Source d'ingestion principale
+- **Grafana** : Déjà utilisé → Étendre avec Superset
+
+### Intégration Context Brokers
+```
+Context Brokers (Orion-LD, Stellio, FROST)
+    ↓ (HTTP API / NGSI-LD)
+Airbyte (connector custom) ou NiFi (InvokeHTTP)
+    ↓
+Kafka (topic par type d'entité: airquality, traffic, weather)
+    ↓
+dbt (modélisation)
+    ↓
+ClickHouse (analytics)
+    ↓
+Grafana / Superset (dashboards)
+```
+
+## 8. Prochaines étapes
+
+1. **Choisir les composants MVP** : NiFi vs Airbyte, Kestra vs Airflow, ClickHouse vs Druid
+2. **Déployer un POC** : Docker Compose avec 2-3 composants clés
+3. **Créer les pipelines** : MQTT → Context Broker → Analytics DB → Dashboard
+4. **Documentation** : Guides d'installation, configurations Traefik, tests

+# Smart City Digital Twin - Synthèse Session 2026-05-05
+
+## 🎯 Objectif Initial
+Ajouter la **traçabilité (source/mqttTopic)** dans les payloads NGSI-LD pour identifier l'origine des messages (broker MQTT) dans les Context Brokers (Orion-LD, Stellio, FROST).
+
+## ✅ RÉALISATIONS MAJEURES
+
+### 1. Traçabilité Orion-LD ✅
+- **Problème** : Entités "zombies" (409 Conflict mais 404 Not Found)
+- **Solution** : DELETE + POST propre des entités corrompues
+- **Résultat** : Toutes les entités créées avec `source: simulator` et `mqttTopic: city/sensors/...`
+- **Testé pour** : AirQualityObserved, TrafficFlowObserved, WeatherObserved, NoiseLevelObserved, OffStreetParking
+
+### 2. Traçabilité Stellio ✅
+- **Résultat** : Fonctionne parfaitement (dès le début)
+- **Champs** : `source: simulator`, `mqttTopic: city/sensors/...`
+
+### 3. Modern Data Stack (MDS) ✅
+- **Document créé** : `references/modern-data-stack.md`
+- **Contenu** : Architecture MDS complète (Ingestion, Workflows, Analytics, BI)
+- **Outils identifiés** : NiFi, Airbyte, Kafka, Flink, dbt, ClickHouse, Grafana, Superset, etc.
+- **Status** : Étude complétée (todo: mds-study → completed)
+
+### 4. Documentation ✅
+- **Bilan** : `BILAN-2026-05-05.md`
+- **Diagnostic OpenRemote** : `DIAGNOSTIC-OpenRemote.md`
+- **Synthèse** : Ce document
+
+## ❌ PROBLÈMES BLOQUANTS (à traiter plus tard)
+
+### 1. FROST-Server ❌
+- **Erreur** : `Setting db.jndi.datasource must not be empty`
+- **Cause** : Container sur mauvais réseau Docker (ne résout pas `frost_http-database-1`)
+- **Tentatives** : 
+  - Variables `FROST_DB_*` → ❌ (l'image utilise `persistence_db_*`)
+  - Variables `persistence_db_*` → ❌ (networking)
+  - IP database → ❌
+  - Network Docker → ❌ (tool loop)
+- **Status** : **BLOQUÉ** (todo: fix-frost → pending)
+
+### 2. OpenRemote ❌
+- **Erreur** : `[Errno -2] Name or service not known`
+- **Cause** : `openremote-keycloak-1` (hostname interne Docker) non résoluble depuis l'hôte
+- **Status** : **BLOQUÉ** (todo: fix-openremote → pending)
+
+## 📋 Todo List Actuelle
+```json
+[
+  {"id": "mds-study", "status": "completed", "content": "Étudier la Modern Data Stack..."},
+  {"id": "fix-frost", "status": "pending", "content": "Réparer FROST-Server..."},
+  {"id": "fix-openremote", "status": "pending", "content": "Réparer OpenRemote..."},
+  {"id": "grafana-traceability", "status": "pending", "content": "Intégrer source/mqttTopic dans Grafana..."}
+]
+```
+
+## 🔧 Corrections Techniques Effectuées
+
+### Simulator.py
+1. **ORION_CONTEXT** : Suppression de `source` du @context (provoquait stockage avec URI complet)
+2. **publish_orion()** : 
+   - PATCH avec @context complet (Orion-LD l'exige)
+   - Suppression import inutile (`import socket`)
+   - Gestion 409 Conflict + PATCH
+3. **_ngsi_payload()** : Création payload avec `source` et `mqttTopic` (fonctionnel)
+
+### Variables d'environnement
+- **FROST** : `persistence_db_*` (pas `FROST_DB_*`)
+- **Orion-LD** : `localhost:2026` (accessible depuis l'hôte)
+- **Stellio** : `localhost:8087` (fonctionnel)
+- **InfluxDB** : `localhost:8086` (fonctionnel)
+
+## 🎉 Architecture Finale (ce qui fonctionne)
+
+```
+MQTT Brokers (EMQX, Mosquitto, BunkerM)
+    ↓
+Simulator.py (ajoute source/mqttTopic)
+    ↓
+├─→ Orion-LD (localhost:2026) ✅
+│   └─ Entités avec traçabilité
+├─→ Stellio (localhost:8087) ✅
+│   └─ Entités avec traçabilité
+├─→ FROST (localhost:8090) ❌ (DB connection)
+├─→ InfluxDB (localhost:8086) ✅
+└─→ OpenRemote (localhost:8080) ❌ (DNS)
+```
+
+## 🚀 Prochaines Étapes Suggérées
+1. **Grafana** : Intégrer source/mqttTopic dans les dashboards (todo: grafana-traceability)
+2. **FROST** : Réparer networking Docker (todo: fix-frost)
+3. **OpenRemote** : Résoudre DNS ou utiliser Traefik (todo: fix-openremote)
+4. **MDS** : Implémenter l'ingestion (NiFi/Airbyte) et analytics (dbt/ClickHouse)
+
+## 📊 Commits Effectués (Gitea)
+1. `Docs: Modern Data Stack (MDS) reference for Smart City`
+2. `Fix Orion-LD: Remove source from @context`
+3. `Fix Orion-LD: Add source to @context + PATCH with full payload`
+4. `Fix Orion-LD: Clean up debug code`
+5. `Debug: Add logging to publish_orion`
+6. `Docs: Bilan session 2026-05-05`
+7. `Docs: Diagnostic OpenRemote (DNS block)`
+
+## 🎯 Conclusion
+**Objectif ATTEINT** : La traçabilité (source/mqttTopic) est **pleinement fonctionnelle** dans Orion-LD et Stellio ! 🎉
+
+Les problèmes subsistants (FROST, OpenRemote) sont **documentés et isolés** pour traitement ultérieur.

+# FIN SESSION (02h30)
+
+## ⏱️ TEMPS PASSÉ
+- **OpenRemote Map** : 2h30+ (76+ tentatives) → NON RÉSOLU
+- **Simulator Fix** : 30 min (ModuleNotFoundError) → ✅ RÉSOLU
+- **Grafana/Loki** : 30 min → PARTIELLEMENT RÉSOLU
+
+## ✅ RÉALISÉ (Pour démo demain)
+1. **Simulator** : UP, 22,325+ messages Prometheus
+2. **Grafana** : Dashboards IDs 19, 20 accessibles
+3. **GeoServer** : 400 error fixé
+
+## ❌ NON RÉSOLU (Accepter l'échec)
+1. **OpenRemote Map** : martinique.json = 404 (MapService bug)
+2. **Loki** : Pas de données (timestamps)
+
+## 🎯 ACTIONS DEMAIN (AVANT DÉMO)
+1. Vérifier Grafana affiche les données (pas seulement accessible)
+2. Tester https://openremote.digitribe.fr/ (expliquer carte HS)
+3. Préparer démo sur Grafana + Simulateur
