I need a small, reliable tool that watches a few specific product URLs on the Hermes Luxembourg site and lets me know the moment the button changes from “View more” to “Add to cart.” Everything I want to track is public and this type of monitoring is fully permitted, so no concerns on that front. My ideal workflow is simple: • I enter or update the list of product links I care about. • The script pings those pages at a reasonable interval, detects the switch in stock status, and immediately triggers a push notification to my smartphone. A lightweight web-scraper with a clear, maintainable rule for that button-text change should be enough. If you prefer to use Python with requests/BeautifulSoup —or Playwright, Puppeteer, or another headless approach—feel free; the key is fast, accurate detection and rock-solid alerts. Please include brief setup instructions so I can run it on my own machine or a small VPS and add or remove SKUs whenever I need. Deliverables 1. Source code with clear comments. 2. Configuration file or simple UI for adding product URLs. 3. Push notification integration (Firebase, Pushover, or similar) tested on smartphone. 4. Quick start guide covering install, usage, and how to change check intervals. If this sounds straightforward to you, let’s get it running so I never miss an in-stock drop again.
