Extract Prometheus metrics from mid-2020's SMA Sunny Boy inverters with webconnect API method.
Python-only, with no significant dependencies. Pulls data from SMA Sunny Boy inverters, using SMA webconnect API method and presents them as either stdout, file, or local socket "127.0.0.1:/metrics" output for Prometheus scraping.
Older SMA devices use different protocol (speedwire - UDP) - see https://github.com/johnhtodd/sunnyboy-promscraper for that scraper.
