Chat with @BotFather on Telegram\n2. Type `/newbot` \n3. Follow instructions, save the TOKEN\n4. In n8n: Settings → Credentials → Add → Telegram\n5. Enter Bot Token\n\n### 🌤️ Setup BMKG API (Optional)\n- BMKG API is usually free without API key\n- If key required, register at portal.bmkg.go.id\n\n---\n\n## 📥 STEP 3: IMPORT WORKFLOW\n\n### Method 1: Import JSON\n1. Copy entire workflow JSON \n2. In n8n: Menu → Import from File\n3. Paste JSON → Import\n\n### Method 2: Via File Upload\n1. Save JSON as .json file\n2. Drag & drop to n8n workspace\n3. Click Import\n\n---\n\n## ⚙️ STEP 4: WORKFLOW CONFIGURATION\n\n### 🏠 Edit \"Config\" Node\n```\nlocationName: \"Main Pond\" (change according to your pond)\nlat: \"-6.2000\" (latitude coordinates of location)\nlon: \"106.8166\" (longitude coordinates of location)\nadm4: \"31.71.03.1001\" (BMKG area code)\nthresholdProb: \"60\" (rain threshold %, default 60%)\nreducePercent: \"-20\" (feed reduction %, default -20%)\n```\n\n### 📱 Setup Telegram Node\n1. Click \"Telegram: Send Report\" node\n2. Select the credential you created\n3. Fill Chat ID:\n   - Forward message to @userinfobot\n   - Copy the Chat ID that appears\n\n### 🔗 Setup ESP8266 Webhook\n1. Edit esp8266WebhookUrl in Config node\n2. Format: `http://ESP8266_IP/webhook` \n3. Example: `http://192.168.1.100/webhook`\n\n---\n\n## 📡 STEP 5: ESP8266 CONFIGURATION\n\n### Arduino Code Setup\n```cpp\n// Add to ESP8266 Arduino code\n#include <ESP8266WebServer.h>\nESP8266WebServer server(80);\n\nvoid setup() {\n  // Setup WiFi connection\n  // Setup servo, LCD, sensors\n  // Setup webhook endpoint\n  server.on(\"/webhook\", HTTP_POST, handleWebhook);\n  server.begin();\n}\n\nvoid handleWebhook() {\n  String command = server.arg(\"command\");\n  if(command == \"FEED_NORMAL\") {\n    // Normal feed 100%\n    feedFish(100);\n  }\n  else if(command == \"FEED_REDUCE_20\") {\n    // Feed reduced by 20%\n    feedFish(80);  \n  }\n  server.send(200, \"application/json\", \"{\\\"status\\\":\\\"ok\\\"}\");\n}\n```\n\nOr check here: https://github.com/TegarDev9/fish-feed-esp8266.git\n\n---\n\n## ⏰ STEP 6: SET AUTOMATIC SCHEDULE\n\n### Configure Cron Node\n1. Click \"Cron: 05:30 & 16:30 WIB\" node\n2. Set timezone: \"Asia/Jakarta\"\n3. Set time: 05:30 and 16:30 (or as desired)\n\n---\n\n## ✅ STEP 7: TESTING & ACTIVATION\n\n### 🧪 Manual Test\n1. Click first node (Cron)\n2. Select \"Execute Node\" \n3. View results in each node\n4. Make sure there are no red errors\n\n### 🔍 Check Connections\n- ✅ BMKG API response OK\n- ✅ ESP8266 webhook response 200\n- ✅ Telegram message sent\n\n### 🚀 Activate Workflow\n1. Click \"Active\" toggle at top right\n2. Workflow will run automatically on schedule\n\n---\n\n## 🛠️ COMMON TROUBLESHOOTING\n\n### ❌ Error \"Node not found\"\n**Solution:** Update n8n to latest version\n```bash\nnpm update -g n8n\n```\n\n### ❌ Telegram error \"Unauthorized\"\n**Solution:** \n- Check Bot Token is correct\n- Ensure Chat ID is valid\n- Bot already started with /start\n\n### ❌ ESP8266 not responding\n**Solution:**\n- Check ESP8266 IP address\n- Ensure ESP8266 and n8n are on same network  \n- Manual test: `curl -X POST http://IP/webhook`\n\n### ❌ BMKG API timeout\n**Solution:**\n- Check internet connection\n- Change timeout from 30000 to 60000ms\n- Use valid ADM4\n\n---\n\n## 📊 MONITORING & LOGS\n\n### 📈 View Execution History\n1. Menu → Executions\n2. View status of each run\n3. Click for error details\n\n### 📱 Telegram Notifications  \nAutomatic message format:\n```\n🐟 Main Pond - Automatic Feed Schedule\n📅 Time: 17/09/2025 17:30:00\n🌤️ BMKG Weather Analysis:\n• Rain prob. 12 hours: 45%\n🎯 Feed Decision:\n• Feed ratio: 100%\n• ESP8266 Status: ✅ Sent\n```\n\n---\n\n## 🔄 UPDATE & MAINTENANCE\n\n### Update Workflow\n1. Export old workflow (backup)\n2. Import new workflow \n3. Copy old credentials\n4. Test before activation\n\n### Backup Credentials\n1. Settings → Export\n2. Save backup file\n3. Include credentials: YES\n\n---\n\n## 📞 TECHNICAL SUPPORT\n\n### Log Error Checking\n```bash\n# Check n8n logs\ndocker logs n8n\n\n# Or if installed via npm\n~/.n8n/logs/n8n.log\n```\n\n### Performance Tips\n- Use Docker for stability\n- Set sufficient memory limit\n- Monitor disk space for logs"
