PortaSplit Tracker is a Java application that monitors the stock availability of the Midea PortaSplit air conditioner across several German hardware and retail stores, including OBI, toom, Bauhaus, Hornbach, and Globus, as well as Amazon, Lidl, and the classifieds site kleinanzeigen.de. When the product goes from out of stock to available at any of these sources, the app sends a notification through Telegram. The app runs as a Spring Boot web application with a built-in dashboard. The dashboard shows live availability status from each store, a history chart, a change log, and a technical log. A location filter lets you narrow results by postal code and radius, so stores outside your area can be excluded while online shops always count. Each store is handled by a separate worker running independently. The app also integrates with CloakBrowser, a tool that helps avoid bot-detection measures on the retailer websites. The Telegram notification setup requires creating a bot through Telegram's BotFather service and entering the bot token and chat ID into the configuration file. There is an optional alpha feature that can attempt to automatically add the product to a cart and begin the checkout process when stock appears at a supported retailer, with the user confirming the purchase via Telegram. This feature requires encrypted credential storage using an AES key. Installation is done with Docker (the recommended method, which bundles CloakBrowser) or locally using Maven and JDK 21. The README is written in German. This is a hobby project built for personal use. The author states it should not be used to scalp or hoard items, and users are responsible for checking each website's terms of service.
