 ## 📝 Notes 2026-05-26
-- **Grafana** : Dashboard smartcity-martinique-complete v3 — données confirmées (PM2.5, temp, traffic, etc.)
+- **Grafana** : Dashboard smartcity-martinique-complete v4 — données confirmées ✅
 - **Pipeline** : Simulateur → EMQX/Mosquitto → Telegraf → InfluxDB → Grafana ✅
 - **InfluxDB** : bucket `smartcity`, measurement `mqtt_consumer`, tag `topic` pour le type
 - **OpenRemote** : Abandon pour l'instant, l'utilisateur va recloner le répertoire
 - **Keycloak** : Recréé manuellement (ancien supprimé par docker-compose up échoué)
+- **Grafana provisioning** : smart-city-dashboards.json déplacé en .bak pour éviter écrasement

+# Snapshot 2026-05-26 — Smart City Digital Twin Martinique
+
+## État des services
+
+### Pipeline de données ✅ FONCTIONNEL
+```
+Simulateur (60 capteurs) → EMQX + Mosquitto → Telegraf → InfluxDB → Grafana
+```
+
+### Containers UP
+| Container | Status | Notes |
+|-----------|--------|-------|
+| smart-city-simulator | ✅ Up 2j | 60 capteurs, MQTT OK |
+| smart-city-telegraf | ✅ Up | Connecté EMQX + Mosquitto |
+| smart-city-influxdb | ✅ Up healthy | Bucket `smartcity` with data |
+| smart-city-grafana | ✅ Up | Dashboard v3, datasource corrigé |
+| openremote-postgresql | ✅ Up healthy | timescaledb-ha:pg15 |
+| openremote-keycloak | ✅ Up | Recréé manuellement |
+| openremote-manager | ❌ Crash loop | Flyway corrigé mais PG recréé |
+| contexus-app | ⚠️ Unhealthy | Postgres/Redis OK |
+| contexus-postgres | ✅ Up healthy | |
+| contexus-redis | ✅ Up healthy | |
+
+### Containers DOWN (intentionnel pour CPU)
+- ThingsBoard, Pulsar, Redpanda, FROST, Stellio, Orion-LD
+
+## Données InfluxDB confirmées
+- Bucket: `smartcity`
+- Measurement: `mqtt_consumer`
+- Tag `topic`: `smartcity/{type}/{id}` (ex: `smartcity/airquality/1`)
+- Types: airquality(20), parking(20), traffic(10), weather(10), light(5), noise(5)
+
+## Grafana Dashboard
+- UID: `smartcity-martinique-complete`
+- URL: https://grafana.digitribe.fr/d/smartcity-martinique-complete/smart-city-digital-twin-martinique-complet
+- Version: 3 (15 panels, requêtes Flux corrigées)
+- Datasource: InfluxDB-SmartCity-Correct (uid: dd1bfc24-...)
+
+## Fichiers modifiés cette session
+- `grafana-datasources.yml`
+- `grafana-dashboard-smartcity.json`
+- `grafana/provisioning/dashboards/smart-city-dashboards.json`
+- `grafana/provisioning/datasources/datasources.yml`
+- `openremote/docker-compose.yml` (OR_SETUP_TYPE: "default")
+- `TODO.md` (home + projet)
+- `session_resume_2026-05-26.md` (nouveau)
+
+## Commit
+- `5bbd5a6` — "fix: Grafana dashboard 'no data' — datasource + Flux queries"
+- Push Gitea: ❌ (502 Bad Gateway)
+
+## Prochaines étapes
+1. Recloner le répertoire (décision utilisateur)
+2. Relancer OpenRemote après reclonage
+3. Push Gitea quand le serveur sera accessible
+4. Configurer les 60 devices Contexus
+5. Activer BunkerM dans Telegraf
