A HUB75 Football Scoreboard That Only Needs WiFi
Yesterday's scoreboard needed Home Assistant, a HACS integration, and a blueprint. A day later there's a version where you flash the M-1 from a browser, join it to WiFi, tap your team on the device's own page, and that's the whole setup. The ESP32 talks to ESPN itself. This is what it took, including the bug that made every button on my fancy new page silently do nothing.
