+# 📅 Session Smart City Digital Twin — 04 Mai 2026 (Final)
+**Projet :** ~/smart-city-digital-twin-martinique  
+**Reprise de la session :** 03 Mai 2026 (commit 8bb0381fff4cadc213db481795c36d2c03c2deff)
+
+---
+
+## ✅ Réalisations de cette session (04 Mai)
+
+### 1. OpenRemote Authentication Fix
+- Modifié `simulator.py` : `_get_or_token()` utilise maintenant `password grant` avec `client_secret`
+- `client_credentials` testé avec succès (HTTP 200) mais échoue sur API PUT (403 Forbidden)
+- Problème 403 persistait → Nécessite configuration manuelle Keycloak (Service Account Roles)
+
+### 2. Container Networking Fixed
+```bash
+docker network connect openremote_default smart-city-simulator
+docker network connect traefik smart-city-simulator
+docker network connect frost_http_default smart-city-simulator
+```
+
+### 3. Grafana Dashboard Created ✅
+- Datasource InfluxDB ajoutée : `http://digital-twin-influxdb:8086`, database `smartcity`
+- Dashboard importé : UID `smartcity-martinique-2026`
+- **URL** : http://localhost:3001/d/smartcity-martinique-2026/smart-city-digital-twin-martinique
+
+### 4. Skill Updated ✅
+- Skill `smart-city-simulator` mise à jour avec les changements de cette session
+- Section "Session 2026-05-04 Updates" ajoutée
+
+---
+
+## ❌ Blocages restants
+
+1. **OpenRemote 403 Forbidden** : Le client `openremote` (realm `smartcity`) n'a pas les permissions d'écriture sur les assets.
+   - **Solution** : Via Keycloak UI → Realm `smartcity` → Clients → `openremote` → Service Account Roles → Assigner `realm-management` → `manage-clients`
+
+2. **password grant échoue (401)** : L'utilisateur `admin` n'existe pas dans le realm `smartcity`.
+   - **Solution alternative** : Utiliser `client_credentials` mais configurer les permissions du Service Account.
+
+---
+
+## 📋 Commandes utiles (Copier-Coller)
+
+### Vérifier l'état des containers
+```bash
+cd ~/smart-city-digital-twin-martinique
+docker ps --format "table {{.Names}}\t{{.Status}}\t{{.Ports}}" | grep -E "smart-city|openremote|frost|orion|stellio|grafana"
+```
+
+### Accéder au Dashboard Grafana
+```bash
+# Ouvrir dans le navigateur
+xdg-open http://localhost:3001/d/smartcity-martinique-2026/smart-city-digital-twin-martinique
+# Login: admin / Digitribe972
+```
+
+### Corriger OpenRemote 403 (Manuel Keycloak)
+```bash
+# 1. Aller sur https://openremote.digitribe.fr/auth/admin/
+# 2. Login: admin / Digitribe972
+# 3. Sélectionner realm "smartcity"
+# 4. Clients → "openremote" → Tab "Service Account Roles"
+# 5. Add "realm-management" → "manage-clients", "view-clients"
+```
+
+### Rebuild simulator (après correction OpenRemote)
+```bash
+cd ~/smart-city-digital-twin-martinique
+docker build -t smart-city-simulator:latest .
+docker stop smart-city-simulator && docker rm smart-city-simulator
+docker run -d --name smart-city-simulator --network emqx_default \
+  -e SENSOR_COUNT_traffic=3 -e SENSOR_COUNT_airquality=2 \
+  -e SENSOR_COUNT_parking=2 -e SENSOR_COUNT_noise=1 \
+  -e SENSOR_COUNT_weather=1 -e SENSOR_COUNT_light=1 \
+  -e PUBLISH_INTERVAL_SEC=10 -e ENABLE_ORION=1 \
+  -e ENABLE_STELLIO=1 -e ENABLE_FROST=1 -e ENABLE_OPENREMOTE=1 \
+  -e OR_CLIENT_ID=openremote -e OR_CLIENT_SECRET=QVTnyObwXdpQ0Vuc60kFSonidK49FiXb \
+  -e OR_REALM=smartcity -e OR_ADMIN_USER=admin -e OR_ADMIN_PASS=Digitribe972 \
+  smart-city-simulator:latest python -c "import simulator; simulator.main()"
+docker network connect openremote_default smart-city-simulator
+docker network connect traefik smart-city-simulator
+docker network connect frost_http_default smart-city-simulator
+```
+
+### Vérifier les données Grafana (InfluxDB)
+```bash
+docker exec digital-twin-influxdb influx query 'from(bucket:"iot_data") |> range(start:-1h) |> last()'
+```
+
+---
+
+## 📦 Prochaines étapes (Session suivante)
+
+1. **Corriger OpenRemote 403** (via Keycloak UI ou API)
+2. **Valider la remontée des données** dans l'UI OpenRemote Manager (https://openremote.digitribe.fr/manager/ → Realm: Smart City)
+3. **Ajouter des panneaux** au dashboard Grafana (température, humidité, trafic, etc.)
+4. **Pousser les changements sur Gitea** :
+   ```bash
+   cd ~/smart-city-digital-twin-martinique
+   git add simulator.py grafana_dashboard_smartcity.json session_resume_2026-05-04.md
+   git commit -m "Fix OpenRemote auth, add Grafana dashboard, update skill"
+   git push origin master
+   ```
