+2. Open this URL in your browser (replace `YOUR_BOT_TOKEN` with your actual bot token):
+   ```
+   https://api.telegram.org/botYOUR_BOT_TOKEN/getUpdates
+   ```
+3. Look for the `"chat":{"id":` field in the response
+4. The number after `"id":` is your **Chat ID**
+
+#### Method 3: For Group Chats
+1. Add your bot to the group
+2. Send a message in the group
+3. Use the same API URL as Method 2
+4. Look for the chat object with `"type":"group"` or `"type":"supergroup"`
+5. The `"id"` field will be your **Group Chat ID** (usually negative number)
+
+### 3. Get Your Topic ID (For Supergroups with Topics)
+
+If you're using a supergroup with topics enabled:
+
+1. Create or open the topic where you want notifications
+2. Send a message in that specific topic
+3. Use the API URL from Method 2 above
+4. Look for `"message_thread_id"` in the response
+5. This number is your **Topic ID**
+
+#### Alternative Method for Topic ID:
+1. Right-click on a message in the topic
+2. Select "Copy Message Link"
+3. The URL will look like: `https://t.me/c/XXXXXXXXX/YYYY/ZZZZ`
+4. The `YYYY` number is your **Topic ID**
+
+## 🔧 Configuration
+
+Once you have your IDs, add them to your `.env` file:
+
+```env
+# Bot Configuration
+TELEGRAM_BOT_TOKEN=your_bot_token_here
+
+# Chat Configuration
+TELEGRAM_CHAT_ID=your_chat_id_here
+
+# Topic Configuration (optional - only for supergroups with topics)
+TELEGRAM_TOPIC_ID=your_topic_id_here
+```
+
+## ✅ Testing Your Configuration
+
+You can test if your configuration works by running:
+
+```bash
+node scripts/test-startup-notification.js
+```
+
+This will send a test message to verify your Chat ID and Topic ID are correct.
+
+## 🔍 Troubleshooting
+
+### Common Issues:
+
+**Bot can't send messages to group:**
+- Make sure the bot is added to the group
+- Ensure the bot has permission to send messages
+- For channels, make sure the bot is an admin
+
+**Wrong Chat ID:**
+- Group Chat IDs are usually negative numbers
+- Private chat IDs are usually positive numbers
+- Double-check you're using the correct ID format
+
+**Topic ID not working:**
+- Make sure topics are enabled in your supergroup
+- Verify you're getting the Topic ID from the correct topic
+- Topic IDs are only needed for supergroups with topics
+
+**API returns empty:**
+- Send a fresh message to your bot/group
+- Make sure your bot token is correct
+- Check that the bot has received recent messages
+
+## 📝 Notes
+
+- Chat IDs remain constant, so you only need to find them once
+- Topic IDs also remain constant unless the topic is deleted and recreated
+- Keep your bot token secure and never share it publicly
+- For production use, consider using environment variables instead of hardcoding IDs
+
+## 🆘 Need Help?
+
+If you're still having trouble:
+1. Check the bot logs for error messages
+2. Verify your bot token is valid
+3. Ensure the bot has proper permissions in your chat/group
+4. Try sending a test message manually to confirm the setup

+## 🚨 Troubleshooting
+
+### Problem: Not Receiving Startup Notification
+
+**Possible Causes & Solutions:**
+
+1. **Wrong Chat ID**
+   ```bash
+   # Check console logs for your actual Chat ID
+   # Look for: [ACTIVITY] User 123456789: text_message
+   ADMIN_CHAT_IDS=123456789  # Use the number from logs
+   ```
+
+2. **Bot Not Added to Group**
+   - Add bot to your group
+   - Make bot an admin
+   - Use the group's Chat ID (negative number)
+
+3. **Invalid Environment Variable**
+   ```bash
+   # Make sure no spaces around the equals sign
+   ADMIN_CHAT_IDS=123456789  # ✅ Correct
+   ADMIN_CHAT_IDS = 123456789  # ❌ Wrong
+   ```
+
+### Problem: Topic Messages Not Working
+
+**Solutions:**
+1. **Check Topic ID**
+   ```bash
+   # Make sure topic exists and ID is correct
+   MONITORING_TOPIC_ID=5
+   ```
+
+2. **Bot Permissions**
+   - Bot must be admin in the group
+   - Bot must have permission to send messages in topics
+
+3. **Remove Topic Configuration**
+   ```bash
+   # Comment out or remove this line to send to main chat
+   # MONITORING_TOPIC_ID=5
+   ```
+
+### Problem: Too Many/Too Few Health Checks
+
+**Solutions:**
+```bash
+# For less frequent monitoring (every 30 minutes)
+HEALTH_CHECK_INTERVAL_MINUTES=30
+
+# For more frequent monitoring (every 5 minutes)
+HEALTH_CHECK_INTERVAL_MINUTES=5
+
+# For testing (every 1 minute)
+HEALTH_CHECK_INTERVAL_MINUTES=1
+```
+
+### Problem: Memory Usage Shows NaN
+
+**This is automatically fixed in the current version.** If you still see this:
+1. Restart your bot
+2. The system now properly calculates memory usage
+3. You should see actual MB values like "245MB"
+
+### Problem: Bot Permissions Error
+
+**Error Messages & Solutions:**
+
+- `chat not found` → Bot removed from group, re-add it
+- `bot was blocked` → User blocked the bot, use different admin
+- `not enough rights` → Make bot admin in group
+- `topic closed` → Open the topic or remove MONITORING_TOPIC_ID
+
+## 📞 Getting Help
+
+### Quick Diagnostics
+1. **Check Console Logs**: Look for `[MONITOR]` messages
+2. **Test Configuration**: Restart bot and look for startup notification
+3. **Verify Chat ID**: Send message to bot and check console for your ID
+4. **Test Commands**: Try `/system_status` command
+
+### Common Log Messages
+- `✅ Test message sent successfully` → Configuration working
+- `❌ Test message failed` → Check Chat ID and bot permissions
+- `✅ Message sent successfully to -1001234567890 (topic 5)` → Topic working
+- `⚠️ Topic 5 not found` → Check topic ID or remove it
+

+# 🚀 Smart Startup Notification System
+
+## 🎯 Problem Solved
+
+Previously, the bot sent startup notifications every time it restarted during development (with `npm run dev` or nodemon), which was annoying and not useful. Now it only sends startup notifications when it's actually needed.
+
+## ✅ How It Works
+
+### 🧠 **Smart Detection**
+The bot now tracks its state and only sends startup notifications when:
+
+1. **First Run** - Bot starts for the first time (no state file exists)
+2. **After Shutdown** - Bot was properly shut down and is starting again
+3. **After Crash** - Bot crashed and is recovering
+4. **After Long Downtime** - Bot was down for more than 5 minutes (likely a real outage)
+
+### 🚫 **When It WON'T Send Notifications**
+- Development restarts (nodemon, `npm run dev`)
+- Quick restarts within 5 minutes
+- Code changes during development
+
+## 🔧 **New Commands**
+
+### `/bot_state` (Admin Only)
+Check the current bot state and startup history:
+
+```
+🤖 Bot State Information
+
+📊 Current Status: running
+🚀 Last Startup: 05/01/2026, 16:30:25
+🛑 Last Shutdown: 05/01/2026, 16:25:10
+📝 Shutdown Reason: SIGINT (Ctrl+C)
+🔢 Process ID: 12345
+
+💡 Note: Startup notifications are only sent after proper shutdowns or crashes.
+```
+
+## 📁 **State Tracking**
+
+The bot creates a `.bot-state.json` file to track:
+- Current status (running/shutdown/crashed)
+- Last startup time
+- Last shutdown time and reason
+- Last crash time and reason
+- Process ID
+
+This file is automatically managed and added to `.gitignore`.
+
+## 🎯 **Scenarios**
+
+### ✅ **Will Send Startup Notification**
+- You stop the bot with Ctrl+C → Start it again
+- Bot crashes due to error → Restarts automatically
+- Server restarts → Bot starts up
+- Backend API goes down for a while → Comes back online
+
+### ❌ **Won't Send Startup Notification**
+- You save a file during development (nodemon restart)
+- You run `npm run dev` multiple times quickly
+- Quick code changes and restarts
+
+## 🛠️ **Technical Details**
+
+### State File Location
+```
+.bot-state.json (in project root)
+```
+
+### State Tracking Logic
+1. **On Startup**: Check if state file exists and last startup time
+2. **On Shutdown**: Mark state as "shutdown" with reason
+3. **On Crash**: Mark state as "crashed" with error details
+4. **Time Check**: If >5 minutes since last startup, assume it's a real restart
+
+### Graceful Shutdown Handling
+- `Ctrl+C` (SIGINT)
+- `kill` command (SIGTERM)
+- Admin `/shutdown_bot` command
+- Process exit events
+
+## 💡 **Benefits**
+
+1. **Clean Development** - No spam notifications during coding
+2. **Real Alerts** - Only get notified when it matters
+3. **Better Monitoring** - Track actual uptime and downtime
+4. **Debug Info** - `/bot_state` command helps troubleshoot issues
+
+## 🧪 **Testing**
+
+To test the system:
+
+1. **Development Restart** (should NOT notify):
+   ```bash
+   npm run dev
+   # Make a code change (nodemon restarts)
+   # No notification sent
+   ```
+
+2. **Proper Shutdown/Startup** (should notify):
+   ```bash
+   npm run dev
+   # Press Ctrl+C to stop
+   npm run dev
+   # Startup notification sent!
+   ```
+
+3. **Check State**:
+   ```
+   /bot_state
+   # Shows current state and history
+   ```
+
+## 🎉 **Result**
+
+Your monitoring topic will now only receive startup notifications when the bot actually starts up after being down, not during every development restart. This makes the monitoring much cleaner and more useful!
+
+The system is smart enough to distinguish between:
+- 🔄 **Development restarts** (ignored)
+- 🚀 **Real startups** (notified)
+- 💥 **Crash recovery** (notified)
+- 🛑 **Planned shutdowns** (tracked properly)

+# 🔗 Webhook Integration Guide
+
+## 📋 **Current Status: Optimized Mode (No Backend Required)**
+
+Your bot currently uses **optimized polling mode** which works perfectly without any backend integration. It checks for new listings every 6 hours and sends notifications to users.
+
+## 🚀 **Future Webhook Integration (When Backend is Ready)**
+
+### **Step 1: Enable Webhook Mode**
+```env
+# Change in .env file
+NOTIFICATION_MODE=full  # Instead of 'optimized'
+WEBHOOK_PORT=3001
+WEBHOOK_HOST=your-domain.com
+```
+
+### **Step 2: Backend Integration Required**
+
+Your backend will need to send HTTP POST requests to the bot when:
+
+#### **New Listing Created:**
+```javascript
+// Backend code example
+const notifyBot = async (listing) => {
+  try {
+    await fetch('http://your-bot-server:3001/webhook/new-listing', {
+      method: 'POST',
+      headers: { 'Content-Type': 'application/json' },
+      body: JSON.stringify({
+        id: listing.id,
+        title: listing.title,
+        type: listing.type,        // "RENT" or "SALE"
+        price: listing.price,      // Number
+        subcity: listing.subcity,  // "Bole", "Kirkos", etc.
+        houseType: listing.houseType, // "Apartment", "Villa", etc.
+        status: listing.status,    // "ACTIVE", "DRAFT"
+        createdAt: listing.createdAt
+      })
+    });
+    console.log('Bot notified of new listing');
+  } catch (error) {
+    console.error('Failed to notify bot:', error);
+  }
+};
+
+// Call this after creating a listing
+const newListing = await createListing(data);
+await notifyBot(newListing);
+```
+
+#### **Listing Updated:**
+```javascript
+// When listing is updated (price change, status change, etc.)
+const notifyBotUpdate = async (listing) => {
+  await fetch('http://your-bot-server:3001/webhook/update-listing', {
+    method: 'POST',
+    headers: { 'Content-Type': 'application/json' },
+    body: JSON.stringify(listing)
+  });
+};
+```
+
+### **Step 3: Benefits After Integration**
+
+| Feature | Current (Optimized) | With Webhook |
+|---------|-------------------|--------------|
+| **Notification Speed** | Up to 6 hours | 2-5 seconds |
+| **User Experience** | Good | Excellent |
+| **Server Load** | Low | Very Low |
+| **Setup Complexity** | Simple | Requires backend |
+
+## 🛠️ **Backend Requirements**
+
+### **When to Send Webhooks:**
+1. ✅ New listing created with status "ACTIVE"
+2. ✅ Listing updated (price, location, type changes)
+3. ✅ Listing status changed to "ACTIVE"
+4. ❌ Don't send for "DRAFT" listings
+5. ❌ Don't send for deleted listings
+
+### **Webhook Payload Format:**
+```json
+{
+  "id": "listing-uuid",
+  "title": "2BR Apartment in Bole",
+  "type": "RENT",
+  "price": 50000,
+  "subcity": "Bole", 
+  "houseType": "Apartment",
+  "status": "ACTIVE",
+  "createdAt": "2026-01-08T10:00:00Z",
+  "updatedAt": "2026-01-08T10:00:00Z"
+}
+```
+
+### **Error Handling:**
+```javascript
+const notifyBotWithRetry = async (listing, maxRetries = 3) => {
+  for (let i = 0; i < maxRetries; i++) {
+    try {
+      const response = await fetch('http://bot:3001/webhook/new-listing', {
+        method: 'POST',
+        headers: { 'Content-Type': 'application/json' },
+        body: JSON.stringify(listing),
+        timeout: 5000
+      });
+      
+      if (response.ok) {
+        console.log('Bot notified successfully');
+        return;
+      }
+    } catch (error) {
+      console.log(`Webhook attempt ${i + 1} failed:`, error.message);
+      if (i < maxRetries - 1) {
+        await new Promise(resolve => setTimeout(resolve, 1000 * (i + 1))); // Exponential backoff
+      }
+    }
+  }
+  console.error('Failed to notify bot after all retries');
+};
+```
+
+## 🔄 **Migration Plan (Future)**

+
+### **Health Check:**
+```bash
+curl http://your-bot:3001/webhook/health
+```
+
+### **Status Check:**
+```bash
+curl http://your-bot:3001/status
+```
+
+## 🔒 **Security Considerations (Future)**
+
+### **Authentication:**
+```javascript
+// Add API key authentication
+const WEBHOOK_API_KEY = process.env.WEBHOOK_API_KEY;
+
+app.use('/webhook', (req, res, next) => {
+  const apiKey = req.headers['x-api-key'];
+  if (apiKey !== WEBHOOK_API_KEY) {
+    return res.status(401).json({ error: 'Unauthorized' });
+  }
+  next();
+});
+```
+
+### **IP Whitelisting:**
+```javascript
+const ALLOWED_IPS = ['your.backend.ip', '127.0.0.1'];
+
+app.use('/webhook', (req, res, next) => {
+  const clientIP = req.ip;
+  if (!ALLOWED_IPS.includes(clientIP)) {
+    return res.status(403).json({ error: 'Forbidden' });
+  }
+  next();
+});
+```
+
+## 💡 **Summary**
+
+**Current Setup**: Perfect for now! Your bot works great with optimized polling.
+
+**Future Integration**: When your backend is ready, simply:
+1. Add webhook calls to backend
+2. Change `NOTIFICATION_MODE=full`
+3. Restart bot
+4. Enjoy real-time notifications!
+
+The webhook infrastructure is already built and ready - you just need to flip the switch when your backend supports it! 🚀
