Yeah, it's entirely local! The servers run on the Raspberry Pi and serve PNG images over HTTP on the local network β no cloud, no external API, no latency. The Braiins Deck just polls http://192.168.1.x:8080/energy/image directly. Solar data comes live from Home Assistant β the Pi polls the watt value every 30 seconds and calculates kWh itself. The Bitaxe miners have a built-in REST API, so the Pi fetches hashrate, temperature and power consumption directly via HTTP. The Avalon Q uses the cgminer protocol over a raw TCP socket. I don't have much solar unfortunately, mining isn't profitable, but it's a hobby.π
