// Onboard RGB LED demo — WS2812/SK6812 driven directly off the RMT peripheral.
// No USE_LIGHT, no GPIO template, no NeoPixelBus: just rgbLed(gpio, 0xRRGGBB).
//
// Most ESP32-C3/C6/S3 dev boards wire the addressable RGB LED to GPIO8. If that
// pin is assigned to something else in your Tasmota template (e.g. a relay),
// free it first (Backlog GPIO8 0; Restart 1) or pass a different gpio.

    if (step == 1) { rgbLed(pin, 0x002000); }   // dim green
    if (step == 2) { rgbLed(pin, 0x000020); }   // dim blue
