Zigbee Color Dimmable Light Example: wrong RGB values

[wf2020]

Board

ESP32-C6

Device Description

Development Board

Hardware Configuration

GPIO15 connected to LED

Version

latest master (checkout manually)

IDE Name

Arduino IDE

Operating System

Windows 11

Flash frequency

80 MHz

PSRAM enabled

no

Upload speed

921600

Description

Tried the Zigbee Color Dimmable Light Example.
When setting colors with Zigbee2Mqtt (Home Assistant) the RGB values set in the example don't match the values sent:

Setting red to 255 sets red only to 69.
Setting green to 255 sets green only to 34.
Setting blue to 255 sets blue only to 128.

Sketch

ZigbeeColorDimmableLight zbColorLight = ZigbeeColorDimmableLight(ZIGBEE_RGB_LIGHT_ENDPOINT);

/********************* RGB LED functions **************************/
void setRGBLight(bool state, uint8_t red, uint8_t green, uint8_t blue, uint8_t level) {
  if (!state) {
    rgbLedWrite(led, 0, 0, 0);
    return;
  }
  float brightness = (float)level / 255;
  rgbLedWrite(led, red * brightness, green * brightness, blue * brightness);

/*** Output RGB values ***/
  Serial.print("R: ");
  Serial.print(red,DEC);
  Serial.print(" G: ");
  Serial.print(green,DEC);
  Serial.print(" B: ");
  Serial.println(blue,DEC);
}

Debug Message

R: 69 G: 0 B: 0
R: 0 G: 34 B: 0
R: 0 G: 0 B: 128

Hi @wf2020, can you post some more logs from the ESP? Please select in the Arduino IDE Tools menu -> Zigbee mode -> End Device - DEBUG and also set Core Debug Level -> Verbose and post whole log here :)

Also If anyone using Z2M can test this and confirm, I will appreciate the help.

This is the output on color changes:
