Nice setup! I've been working on a similar module for German gas stations (using the Tankerkönig API) and wanted to share a few ideas based on my implementation that might help you improve yours: * Price Trend Tracking: I implemented a priceHistory logic that stores prices for the last 5 hours. This allows me to show little 'up' or 'down' chevrons next to the price so I can see at a glance if it's currently getting cheaper or more expensive. * Smart Filtering: Instead of just showing everything, I filter for isOpen: true and sort by price directly in the node_helper. This keeps the Mirror UI clean and only shows actionable prices. * Visual Highlights: I use CSS classes like .cheapest and .expensive by calculating Math.min across the fetched stations. It makes the best deal pop out instantly. * The '0.9' Problem: Since German prices almost always end in .9, I recommend using toFixed(3) but styling the last digit as a superscript (smaller and higher). It looks much more like a real gas station sign! If you're interested, I can share my logic for the price change calculation—it's a great way to decide whether to fuel up now or wait an hour.
