Service Businesses Diagnose Issues with AI Image Analysis for Professionals

This workflow simplifies plumbing issue assessments for personal use, replacing manual diagnostics with AI analysis of photos and descriptions. The Plumbing Assessment Trigger Webhook receives POST requests with images and details, the Input Validator Code node checks for valid inputs, the AI Vision Analysis HTTP Request node uses Google Vision API to detect objects, labels, and text in images, and the Unified Analysis & Notifications Code node processes results to classify issues, estimate costs, and send optional email/SMS notifications via SendGrid/Twilio. The Response node returns comprehensive results. It helps homeowners and small business owners (1-5 staff) with 50+ monthly issues, enabling quick identification of problems like leaks or clogs without professional tools.\n\nThis workflow saves 3-5 hours weekly for 50 assessments, cutting diagnostic costs by 60%. Use cases include home maintenance, small contractor triage, or DIY repairs. Ideal for individuals or micro-businesses. Requires Google Vision ($1.50/1k units); optional SendGrid ($19.95/month) and Twilio ($0.0079/SMS). Minimal integrations ensure scalability to 200 assessments/month.\n\nInstall n8n from n8n.io or use cloud.n8n.io. Get GOOGLE_VISION_API_KEY at cloud.google.com/vision (enable API, create key). For notifications, obtain SENDGRID_API_KEY from sendgrid.com and TWILIO_ACCOUNT_SID/AUTH_TOKEN/PHONE_NUMBER from twilio.com. Set environment variables: GOOGLE_VISION_API_KEY, optional SENDGRID_API_KEY, TWILIO_ACCOUNT_SID etc. Import JSON, configure Webhook node with POST path 'assess.' Example webhook URL: https://your-n8n-instance/webhook/assess.\n\nTest with Postman: {imageBase64: '...', description: 'leaky faucet'}. Verify logs for analysis and notifications. Common errors: invalid GOOGLE_VISION_API_KEY (regenerate credentials), missing image (add imageBase64), rate limits (wait/retry). Activate workflow in n8n settings. Monitor dashboard executions.
