 ---
 ## 🚀 Schritt-für-Schritt Anleitung
 ### Schritt 1: Bot starten
 #### Option A: QR-Code scannen (empfohlen für Smartphone)
 <p align="center">
  <img src="../public/telegram-bot-qr.png" width="300" alt="Telegram Bot QR Code">
 </p>
 1. Öffne die Kamera-App auf deinem Smartphone
 2. Scanne den QR-Code
 3. Telegram öffnet sich automatisch
 4. Klicke auf **"Start"** oder sende `/start`
 #### Option B: Link öffnen
 1. Klicke auf: **[https://t.me/MeinTracking_bot](https://t.me/MeinTracking_bot)**
 2. Telegram öffnet sich automatisch
 3. Klicke auf **"Start"** oder sende `/start`
 ✅ Du solltest eine Willkommensnachricht vom Bot erhalten
 ---
 ### Schritt 2: Chat ID herausfinden
 #### Option A: Mit @myidbot (empfohlen)
 1. Suche in Telegram nach: **@myidbot**
 2. Sende: `/getid`
 3. Der Bot antwortet sofort mit deiner Chat ID:
   ```
   Your user ID: 123456789
   ```
 4. **Kopiere die Nummer** (z.B. `123456789`)
 #### Option B: Mit @userinfobot
 1. Suche in Telegram nach: **@userinfobot**
 2. Sende: `/start`
 3. Der Bot antwortet mit deinen Informationen:
   ```
   Id: 123456789
   First name: Dein Name
   ...
   ```
 4. **Kopiere die Nummer** bei "Id:" (z.B. `123456789`)
 ---
 ### Schritt 3: Chat ID im Dashboard eintragen
 1. Melde dich im Location Tracker an
 2. Gehe zu: **Einstellungen** → **Benachrichtigungen**
 3. Aktiviere: ☑️ **Telegram Benachrichtigungen**
 4. Trage deine **Chat ID** ein (die Nummer aus Schritt 2)
 5. Klicke auf **"Speichern"**
 ---
 ### Schritt 4: Verbindung testen
 1. Klicke auf den Button **"Telegram Test"**
 2. Du solltest sofort eine Test-Nachricht in Telegram erhalten:
   ```
   ✅ Telegram Connection Test
   Die Verbindung funktioniert!
   ```
 ✅ **Fertig!** Ab jetzt erhältst du alle Geofence-Benachrichtigungen auch per Telegram.
 ---
 ## 📨 Beispiel-Benachrichtigung
 So sieht eine Geofence-Benachrichtigung aus:
 ```
 🟢 Geofence BETRETEN
 📱 Device: Mein iPhone
 📍 Geofence: Zuhause
 🕐 Zeit: 04.12.25, 14:30
 📊 Ereignis: Hat Zuhause betreten
 ```
 **+ Standort-Pin auf der Karte**
 **+ Buttons:**
 - 🗺️ Auf Karte zeigen
 - 📊 Dashboard öffnen
 ---
 ## ❓ Häufige Fragen
 ### Kann ich sowohl Email als auch Telegram aktivieren?
 Ja! Du kannst beide Kanäle gleichzeitig nutzen:
 - ☑️ E-Mail Benachrichtigungen
 - ☑️ Telegram Benachrichtigungen
 ### Sehen andere User meine Benachrichtigungen?
 **Nein!** Jede Chat ID ist ein privater 1-zu-1 Chat. Andere User können deine Nachrichten nicht sehen, auch wenn sie den gleichen Bot nutzen.
 ### Was ist, wenn die Chat ID falsch ist?
 Dann erhältst du keine Benachrichtigungen. Nutze den "Telegram Test" Button, um die Verbindung zu prüfen.
 ### Kann ich Benachrichtigungen pausieren?
 Ja! Deaktiviere einfach "Telegram Benachrichtigungen" in den Einstellungen. Deine Chat ID bleibt gespeichert.
 ### Wo finde ich meine Chat ID nochmal?
 Sende `/getid` an **@myidbot** oder `/start` an **@userinfobot** in Telegram.
 ---
 ## 🛠️ Troubleshooting
 ### "No Telegram chat ID configured"
 → Du hast noch keine Chat ID eingetragen. Folge Schritt 2 und 3.
 ### "Failed to send test message"
 Mögliche Ursachen:
 1. **Chat ID falsch** → Überprüfe die Nummer bei @userinfobot
 2. **Bot nicht gestartet** → Sende `/start` an @MeinTracking_bot
 3. **Bot blockiert** → Entsperre den Bot in Telegram
 ### Test-Nachricht kommt nicht an
 1. Überprüfe, ob du den Bot gestartet hast (`/start` an @MeinTracking_bot)
 2. Prüfe, ob die Chat ID korrekt ist (keine Leerzeichen, keine Buchstaben)
   - Hole sie neu mit `/getid` an @myidbot
 3. Stelle sicher, dass du den Bot nicht blockiert hast

 ## 📞 Support
 Bei Problemen wende dich an den Administrator oder überprüfe die Logs im System.

 # 🚀 Telegram Integration - Setup Guide
 ## ✅ Was wurde implementiert
 ### Dateien erstellt:
 1. **Backend Services:**
   - `lib/telegram-service.ts` - Telegram API Integration
   - `lib/notification-settings-db.ts` - Datenbank-Layer für Settings
   - `lib/geofence-notifications.ts` - Erweitert für Multi-Channel (Email + Telegram)
 2. **Database:**
   - `scripts/init-notification-settings.js` - DB Init Script
   - Tabelle: `UserNotificationSettings` erstellt
 3. **API Endpoints:**
   - `GET/PATCH /api/users/[id]/notification-settings` - Settings verwalten
   - `POST /api/users/[id]/notification-settings/test` - Test-Nachricht
 4. **Admin UI:**
   - `app/admin/settings/notifications/page.tsx` - Settings Page mit QR Code
 5. **Dokumentation:**
   - `docs/telegram-anleitung.md` - User-Anleitung
   - `docs/telegram-setup.md` - Dieses Dokument
   - `public/telegram-bot-qr.png` - QR Code für Bot
 ---
 ## 🔧 Installation & Setup
 ### 1. Dependencies installiert
 ```bash
 ✅ npm install axios
 ✅ npm install qrcode
 ```
 ### 2. Datenbank initialisiert
 ```bash
 ✅ node scripts/init-notification-settings.js
 ```
 Die Tabelle `UserNotificationSettings` wurde erstellt mit:
 - `user_id` (PK, FK → User.id)
 - `email_enabled` (0/1)
 - `telegram_enabled` (0/1)
 - `telegram_chat_id` (TEXT)
 - `created_at`, `updated_at`
 ---
 ## 📱 Bot Setup
 ### Telegram Bot erstellen (für Admin):
 1. Öffne Telegram und suche: **@BotFather**
 2. Sende: `/newbot`
 3. Folge den Anweisungen:
   - Bot Name: `MeinTracking Bot` (oder anders)
   - Bot Username: `MeinTracking_bot` (muss auf `_bot` enden)
 4. BotFather gibt dir einen Token: `1234567890:ABCdefGHIjklMNOpqrsTUVwxyz`
 5. **Wichtig:** Token NIEMALS committen!
 ### .env konfigurieren:
 ```bash
 # .env oder .env.local
 TELEGRAM_BOT_TOKEN=1234567890:ABCdefGHIjklMNOpqrsTUVwxyz
 ```
 ---
 ## 🎯 Für User: Bot aktivieren
 **Schritt-für-Schritt siehe:** `docs/telegram-anleitung.md`
 **Kurzversion:**
 1. Bot starten: [https://t.me/MeinTracking_bot](https://t.me/MeinTracking_bot) oder QR scannen
 2. Chat ID holen: `@myidbot` → `/getid` (oder `@userinfobot` → `/start`)
 3. Im Dashboard: Settings → Notifications → Chat ID eintragen
 4. Test Button drücken
 ---
 ## 🧪 Testing
 ### 1. QR Code generieren
 ```bash
 npm run telegram:qr
 ```
 Erstellt: `public/telegram-bot-qr.png`
 ### 2. Datenbank neu initialisieren
 ```bash
 npm run db:init:notifications
 ```
 Oder alles zusammen:
 ```bash
 npm run db:init
 ```
 ### 3. Test-Nachricht senden
 **Option A: Über Admin UI**
 - Navigiere zu: `/admin/settings/notifications`
 - Telegram aktivieren
 - Chat ID eintragen
 - Button "Telegram Test" klicken
 **Option B: Direkt via Script**
 Erstelle `scripts/test-telegram.js`:
 ```javascript
 const { telegramService } = require('../lib/telegram-service');
 const CHAT_ID = '123456789'; // Deine Chat ID
 async function test() {
  await telegramService.testConnection(CHAT_ID);
 }
 test();
 ```
 ```bash
 TELEGRAM_BOT_TOKEN=dein_token node scripts/test-telegram.js
 ```
 ---
 ## 🔐 Sicherheit & Privacy
 ### Wie funktioniert die Privacy?
 - **1 Bot für alle User** (in `.env`)
 - **Jeder User hat eigene Chat ID** (in DB)
 - **Bot sendet nur an spezifische Chat ID** → Privater 1-zu-1 Chat
 - **User A sieht NIEMALS Nachrichten von User B**
 ### Telegram API Garantie:
 ```typescript
 telegram.sendMessage(chatId: "123456789", text: "...")
 → Geht NUR an Chat ID 123456789
 → Andere Chat IDs können dies NICHT sehen
 ```
 ### Vergleich:
 Wie Email: 1 SMTP-Server (Bot) sendet an verschiedene Adressen (Chat IDs)
 ---
 ## 📊 Wie es funktioniert
 ### Notification Flow:
 ```
 1. Device triggers Geofence
   ↓
 2. geofence-engine.ts erkennt Event
   ↓
 3. GeofenceEvent in DB erstellt
   ↓
 4. geofence-notifications.ts aufgerufen
   ↓
 5. getUserNotificationSettings(owner_id)
   ↓
 6. Parallel execution:
   ├─→ Email (if enabled)
   └─→ Telegram (if enabled)
       ↓
       ├─→ Text mit Emoji, Device, Geofence, Zeit
       ├─→ Inline Buttons (Karte, Dashboard)
       └─→ Location Pin
 ```
 ### Multi-Channel Strategy:
 - **Promise.allSettled()** → Beide parallel
 - **Mind. 1 erfolgreich** → Event als "sent" markiert
 - **Beide fehlgeschlagen** → Event als "failed" markiert
 - **Robust:** Email-Fehler betrifft nicht Telegram (und umgekehrt)

 ## 🛠️ NPM Scripts
 ```bash
 # Datenbank initialisieren
 npm run db:init                    # Alles (inkl. Notifications)
 npm run db:init:notifications      # Nur Notifications Tabelle
 # QR Code generieren
 npm run telegram:qr                # Erstellt public/telegram-bot-qr.png
 # Testing
 npm run test:geofence              # Geofence Event simulieren
 npm run test:geofence:email        # Email Notification testen
 ```
 ---
 ## 📝 Telegram Message Format
 ### Enter Event:
 ```
 🟢 Geofence BETRETEN
 📱 Device: Mein iPhone
 📍 Geofence: Zuhause
 🕐 Zeit: 04.12.25, 14:30
 📊 Ereignis: Hat Zuhause betreten
 ```
 **+ Location Pin** (Karte mit exakter Position)
 **+ Buttons:**
 - 🗺️ Auf Karte zeigen → `/map?lat=...&lon=...`
 - 📊 Dashboard öffnen → `/admin/geofences/events`
 ### Exit Event:
 ```
 🔴 Geofence VERLASSEN
 📱 Device: Mein iPhone
 📍 Geofence: Zuhause
 🕐 Zeit: 04.12.25, 18:45
 📊 Ereignis: Hat Zuhause verlassen
 ```
 ---
 ## 🚨 Troubleshooting
 ### "Cannot find module telegram-service"
 → TypeScript nicht kompiliert. Lösung:
 ```bash
 npm run build
 ```
 Oder für Development:
 ```bash
 npm run dev
 ```
 ### "Telegram bot token not configured"
 → `.env` fehlt `TELEGRAM_BOT_TOKEN`
 ### "Failed to send test message"
 **Mögliche Ursachen:**
 1. Bot nicht gestartet (`/start` an @MeinTracking_bot)
 2. Chat ID falsch
 3. Bot blockiert
 4. Token falsch/abgelaufen
 **Debug:**
 ```bash
 # Check .env
 cat .env | grep TELEGRAM
 # Check DB
 sqlite3 data/database.sqlite "SELECT * FROM UserNotificationSettings;"
 # Test Telegram API direkt
 curl https://api.telegram.org/bot<TOKEN>/getMe
 ```
 ### QR Code wird nicht angezeigt
 → Prüfen ob Datei existiert:
 ```bash
 ls -la public/telegram-bot-qr.png
 ```
 Falls nicht:
 ```bash
 npm run telegram:qr
 ```
 ---
 ## 📚 Environment Variables
 ```bash
 # Required für Telegram
 TELEGRAM_BOT_TOKEN=<dein_bot_token>
 # Optional (für Map/Dashboard Links)
 NEXTAUTH_URL=https://deine-domain.de
 ```
 ---
 ## 🎯 Nächste Schritte
 **Für Produktion:**
 1. ✅ `.env.production` mit echtem Bot-Token erstellen
 2. ✅ Datenbank migrieren: `npm run db:init`
 3. ✅ QR Code generieren: `npm run telegram:qr`
 4. ✅ User-Anleitung teilen: `docs/telegram-anleitung.md`
 5. ✅ Test durchführen mit echtem Device
 **Optional:**
 - Push Notifications hinzufügen
 - SMS Integration
 - Webhook Support
 - Notification History UI
 - Per-Geofence Settings (nicht global)
