Nightly Competitor Price Monitoring with EnConvert & n8n Data Tables

Nightly competitor price monitoring that alerts only when it truly changes

This n8n workflow runs every night at 02:00 to scrape competitor pricing pages with EnConvert, compares the readable page content against a stored SHA-256 snapshot in n8n Data Tables, and logs an alert only when the content actually changes (or when a page is blocked/unreadable).

What this workflow does

• Scheduled execution: Triggers nightly at 02:00.
• Loads watch list & snapshots: Reads the current “Pages to watch” URL list and fetches existing snapshots from Data Tables.
• Scrapes with EnConvert: Uses EnConvert to extract the main page content as markdown.
• Skips unreadable pages: Checks EnConvert’s render_quality and blocked/error flags; if a page can’t be read properly, it logs a skipped_blocked event.
• Detects real changes: Hashes the readable markdown with SHA-256 and compares it to the last stored hash for the same URL.
• Logs only meaningful updates:
  • If the hash differs, logs a changed event to enconvert_alerts and upserts the new hash + timestamp to enconvert_snapshots.
  • If the hash matches, updates the snapshot’s checked_at and content_hash record.

Use cases

• Monitor competitor pricing pages to detect cost changes without noisy alerts.
• Track multiple pricing URLs and maintain historical checks in n8n Data Tables.
• Operational visibility when competitor pages block scraping or degrade in render quality.

Technical details

• EnConvert credential added in n8n.
• Data Tables:
  • enconvert_snapshots (url, content_hash, checked_at, render_quality)
  • enconvert_alerts (url, event, detail, render_quality)
• Nodes/tools referenced in the workflow: if, set, crypto, split out, data table, and a sticky note.
• Optional notifications: You can replace Data Table alert logging with Slack or email nodes for push updates.
