+# Plan: E-Mail-basierte EDA-Kommunikation
+
+## Ziel
+
+Ersetze die aktuelle vollständige EDA-Simulation durch eine reale E-Mail-basierte Kommunikation mit dem EDA-Netzwerk (Netzbetreiber). Simulator bleibt als `@Profile("!prod")`-Fallback. Architektur erlaubt später einfachen Wechsel zu Messenger-API.
+
+---
+
+## Aktueller Stand
+
+### Was existiert
+
+- `EdaConsentService` (Interface) + `SimulatedEdaConsentService` (immer aktiv, kein @Profile)
+- `EdaTopologyService` (Interface) + `SimulatedEdaTopologyService` (immer aktiv)
+- `MailService` (Interface) für User-Verifizierung, nicht für EDA
+- `spring-boot-starter-restclient` im pom.xml (nicht verwendet)
+- `DataSource`-Enum hat `EMAIL_XLSX` aber kein automatisches E-Mail-Polling
+- Kommentar in `EdaCommunicationEventListener:66`: "entweder via Webhook oder Mailbox"
+
+### Was fehlt
+
+- Keine reale EDA-Kommunikation (kein HTTP, kein E-Mail-Versand an EDA)
+- Keine automatische Verbrauchsdaten-Ingestion via E-Mail
+- Simulator hat kein `@Profile` - immer aktiv, auch in prod
+
+---
+
+## Architektur-Entscheidung: Strategy Pattern
+
+```
+                        ┌─────────────────────────┐
+                        │   EdaConsentService      │  (Interface - bleibt unverändert)
+                        │   EdaTopologyService     │
+                        └─────────┬───────────────┘
+                                  │
+              ┌───────────────────┼───────────────────┐
+              │                   │                   │
+    ┌─────────▼──────────┐ ┌─────▼───────────┐ ┌────▼──────────────┐
+    │ SimulatedEda*      │ │ EmailEda*       │ │ MessengerEda*     │
+    │ @Profile("!prod")  │ │ @Profile("prod")│ │ (später)          │
+    └────────────────────┘ └─────────────────┘ └───────────────────┘
+```
+
+---
+
+## Umsetzungs-Schritte
+
+### Schritt 1: Simulator mit @Profile versehen
+
+**Dateien:**
+- `eeg_backend/.../mako/service/impl/SimulatedEdaConsentService.java`
+- `eeg_backend/.../mako/service/impl/SimulatedEdaTopologyService.java`
+
+**Änderung:**
+```java
+// Vorher:
+@Service
+public class SimulatedEdaConsentService implements EdaConsentService {
+
+// Nachher:
+@Profile("!prod")
+@Service
+public class SimulatedEdaConsentService implements EdaConsentService {
+```
+
+**Hinweis:** `@Profile("!prod")` statt `@Profile("dev")` - so sind die Simulatoren auch ohne Profil (z.B. in Tests) verfügbar. Die `EdaCommunicationEventListener` hat kein Profil und braucht immer einen `EdaConsentService` + `EdaTopologyService`.
+
+---
+
+### Schritt 2: EDA E-Mail-Konfiguration
+
+**application-prod.yml (ergänzen):**
+
+```yaml
+eda:
+  email:
+    gateway-address: ${EDA_GATEWAY_EMAIL:eda-gateway@example.com}
+    poll-interval-ms: ${EDA_POLL_INTERVAL_MS:900000}
+    imap:
+      host: ${EDA_IMAP_HOST:}
+      port: ${EDA_IMAP_PORT:993}
+      username: ${EDA_IMAP_USERNAME:}
+      password: ${EDA_IMAP_PASSWORD:}
+      folder: INBOX
+      protocol: imaps
+    smtp:
+      host: ${EDA_SMTP_HOST:}
+      port: ${EDA_SMTP_PORT:587}
+      username: ${EDA_SMTP_USERNAME:}
+      password: ${EDA_SMTP_PASSWORD:}
+```
+
+**application-dev.yml (ergänzen):**
+
+```yaml
+eda:
+  email:
+    gateway-address: test-eda@example.com
+    poll-interval-ms: 900000
+```
+
+---
+
+### Schritt 3: E-Mail-basierte Consent-Implementierung
+
+#### EDA-E-Mail-Format (Hinweis)
+
+Das EDA-Netzwerk (Elektrizitäts-Daten-Austausch) in Österreich nutzt für E-Mail-Kommunikation typischerweise:
+
+- **Betreff:** Strukturiert mit AT-Nummer + Nachrichtentyp (z.B. `CMRequest|AT...` für Consent)
+- **Body:** XML oder strukturiertes Textformat mit AT-Nummer, Entscheidung, Referenz-ID
+- **Attachments:** XLSX/CSV für Verbrauchsdaten
+- **Zentraler Empfänger:** EDA-Gateway leitet an Netzbetreiber weiter (wie beim Messenger)
+
+Die genaue Spezifikation muss vom EDA-Gateway-Anbieter bestätigt werden. Die Architektur ist flexibel gehalten.
+
+#### Neue Dateien
+
+**EmailEdaConsentService.java** - Prod Consent via SMTP:
+- `@Profile("prod")`
+- Implementiert `EdaConsentService`
+- `sendConsentRequest()`:
+  1. Baut Consent-E-Mail auf (AT-Nummer, Typ, Portal-Referenz-ID)
+  2. Versendet an `eda.email.gateway-address` via SMTP
+  3. Speichert Request-Metadaten für Zuordnung der Antwort
+  4. Logging
+
+**EdaMailSender.java** - E-Mail-Versand:
+- Hilfsklasse zum Aufbau und Versand von EDA-E-Mails
+- Consent-Request-E-Mail Vorlage (XML-Format)
+- `@Async` für nicht-blockierenden Versand
+
+**EdaMailParser.java** - E-Mail-Parsing:
+- Hilfsklasse zum Parsen von EDA-E-Mails
+- Erkennt E-Mail-Typ (Consent-Antwort vs. Verbrauchsdaten)
+- Extrahiert AT-Nummer, Entscheidung, Referenz-ID
+- Flexibel: E-Mail-Format-Konfiguration via Properties
+
+**EdaMailPoller.java** - IMAP-Polling:
+- `@Profile("prod")`
+- `@Scheduled(fixedDelayString = "${eda.email.poll-interval-ms:900000}")` - alle 15 Minuten
+- Verbindet sich via IMAP zum EDA-Postfach
+- Parst eingehende E-Mails:
+  - **Consent-Antwort:** Erkennt AT-Nummer + Entscheidung (approved/rejected)
+  - **Verbrauchsdaten-Attachment:** Erkennt XLSX/CSV
+- Für Consent-Antworten:
+  - Veröffentlicht `MakoConsentApprovedEvent` / `MakoConsentRejectedEvent` / `MakoConsentTechnicalFailedEvent`
+- Für Verbrauchsdaten:
+  - Nutzt bestehenden `XlsxMeteringDataParser` für XLSX
+  - Speichert via `MeteringDataService`
+  - Erstellt `MeteringDataUpload`-Audit-Eintrag
+
+---
+
+### Schritt 4: Verbrauchsdaten-Ingestion via E-Mail
+
+**Integration in EdaMailPoller:**
+
+Der Poller erkennt eingehende E-Mails mit Verbrauchsdaten-Attachments:
+
+1. **Mail-Scan:** Durchsucht Postfach nach neuen E-Mails mit Attachments
+2. **Attachment-Erkennung:** XLSX, CSV (je nach EDA-Standard)
+3. **Parsing:** Nutzt `XlsxMeteringDataParser` (bestehend)
+4. **Speicherung:** Ruft `MeteringDataService.uploadMeteringData()` auf
+5. **Audit:** Erstellt `MeteringDataUpload` mit `DataSource.EMAIL_AUTO`
+
+**DataSource erweitern:**
+- `DataSource.java` - `EMAIL_AUTO` hinzugefügt
+
+---
+
+### Schritt 5: Tests
+
+**Neue/angepasste Dateien:**
+- `EmailEdaConsentServiceTest.java` - Mock SMTP, verify E-Mail-Inhalt
+- `EdaMailParserTest.java` - Test verschiedener E-Mail-Formate
+- `EdaMailPollerTest.java` - Unit-Test für Polling-Logik
+- `SimulatorProfileTest.java` - Verifiziere @Profile("!prod")
+
+---

+## Datei-Übersicht
+
+| Aktion | Datei |
+|--------|-------|
+| Ändern | `SimulatedEdaConsentService.java` - @Profile("!prod") |
+| Ändern | `SimulatedEdaTopologyService.java` - @Profile("!prod") |
+| Ändern | `application-prod.yml` - EDA E-Mail-Konfiguration |
+| Ändern | `application-dev.yml` - EDA Dev-Konfiguration |
+| Ändern | `DataSource.java` - EMAIL_AUTO hinzufügen |
+| Neu | `EmailEdaConsentService.java` - Prod Consent via SMTP |
+| Neu | `EdaMailSender.java` - E-Mail-Versand |
+| Neu | `EdaMailParser.java` - E-Mail-Parsing |
+| Neu | `EdaMailPoller.java` - IMAP-Polling (15 Min) für Antworten + Verbrauchsdaten |
+| Neu | Tests |
+
+---
+
+## Verifizierung
+
+1. **Dev-Modus:** `@Profile("!prod")` aktiv → Simulator wird geladen, kein EDA-Mail-Poller
+2. **Prod-Modus:** `@Profile("prod")` aktiv → `EmailEdaConsentService` + `EdaMailPoller` werden geladen
+3. **Unit-Tests:** `mvn test -pl eeg_backend` - alle Tests grün (232 Tests)
+4. **Integrationstest:**
+   - Dev: Konsistenter Flow mit Simulator (AT-Nummer endet mit REJECT/ERROR)
+   - Prod: Echte SMTP/IMAP-Verbindung testen (kann mit Test-Server)
+5. **Manuell prüfen:**
+   - Consent-Flow: User registrieren → Admin genehmigen → MeteringPoint wechselt zu WAITING_FOR_CONSENT
+   - Simulator: AT-Nummer "AT0010001234567890123456789012345" → Consent Approved nach Delay
+   - E-Mail: Echte E-Mail wird an Gateway gesendet
+
+---
+
+## Offene Fragen
+
+1. **EDA-Spezifikation:** Die genaue E-Mail-Format-Spezifikation muss vom EDA-Gateway-Anbieter bezogen werden. Die Architektur ist flexibel gehalten (Konfiguration via Properties).
+2. **Polling-Intervall:** **Entschieden: alle 15 Minuten** (Standardwert in Konfiguration, konfigurierbar).
+3. **Fehlerbehandlung:** Was passiert bei nicht zuordenbaren E-Mails? (Log + Flag) - Muss noch definiert werden.
+4. **Verbrauchsdaten-Format:** XLSX oder CSV? (XLSX-Parsing existiert bereits) - Muss mit EDA-Gateway-Anbieter abgestimmt werden.
+

+

+
+**Status: ABGESCHLOSSEN**
