wtf is goodwe-solarapp?

This project lets you monitor a GoodWe solar inverter right from your own home network, without relying on the manufacturer's cloud portal or slow mobile app. If you have solar panels and want to see detailed, real-time stats and historical data locally, this tool gives you a personalized dashboard for your energy production. Instead of depending on an internet connection to view your solar data, this setup polls your inverter directly on your local network every minute and stores the results. It bundles several tools together: a small app that talks to the inverter and shows current status, a database component that collects metrics over time, and a visualization tool called Grafana that displays everything in premade charts and graphs. You get a web page showing live inverter stats and richer dashboards for browsing historical trends. The primary audience is a homeowner with a compatible GoodWe inverter who enjoys tinkering and wants more control over their energy data than the official apps provide. For example, if your internet goes down but you still want to check how much power your panels generated today, or if you want custom charts that the manufacturer's portal doesn't offer, this gives you that independence. The author notes it was built for a specific inverter model, so someone with a different model would need to adapt the code. A few tradeoffs are worth noting. The author acknowledges that some calculations, like daily generation totals, may not be perfectly accurate compared to the official portal. Polling frequency is also limited to once per minute, since querying the inverter more frequently can overwhelm it and cause it to stop responding. The project is provided as-is and assumes you are comfortable running containers and editing a configuration file to point the app at your inverter's local IP address.
