Extract Prometheus metrics from older Sunny Boy inverters via UDP
Python-only, with no significant dependencies. Pulls data from SMA Sunny Boy inverters, using UDP Speedwire format, and presents them as either stdout, file, or local socket "127.0.0.1:/metrics" output for Prometheus scraping.
Newer devices use different protocol via port 443. See https://github.com/johnhtodd/sunnyboy-promscraper-webconnect for that scraper.
