### Board XIAO ESP32-C6 ### Device Description Raw board, disconnected from everything ### Hardware Configuration Raw board, disconnected from everything ### Version latest stable Release (if not listed below) ### IDE Name VSCode + Platformio ### Operating System NA ### Flash frequency NA ### PSRAM enabled yes ### Upload speed 115200 ### Description When I initialize a Zigbee color dimmable light in code to have a color value of RGB(4, 255, 0), I get an error message when the ZigbeeColorDimmableLight code tries to set the color: ``` Bus 1: Light change - State: OFF, RGB: (4,255,0), Level: 99 [ 6303][E][ZigbeeColorDimmableLight.cpp:180] setLight(): Failed to set light saturation: 0x87: Invalid value ``` Doing some digging, what it appears is happening is that the function to [convert RGB color to HSV color](https://github.com/espressif/arduino-esp32/blob/21640ac82a1bb5efa8cf0b3841be1ac80add6785/cores/esp32/ColorFormat.c#L92-L119) is called as part of `setLight`, and the results are then passed - unadjusted - to `esp_zb_zcl_set_attribute_val`. The issue is that `espRgbColorToHsvColor` can return a saturation value from 0-255, but the valid range for Zigbee is 0-254. ### Sketch ```cpp Although I have not tested this as I don't have the Arduino IDE, I believe this example should cause the error due to the addition of Line 118 to the stock example: https://gist.github.com/thorrak/c3e957ed79313b80655e2ab666d662c5 Line 118 is the only line that differs from the stock example. ``` ### Debug Message ```plain [ 6303][E][ZigbeeColorDimmableLight.cpp:180] setLight(): Failed to set light saturation: 0x87: Invalid value ``` ### Other Steps to Reproduce _No response_ ### I have checked existing issues, online documentation and the Troubleshooting Guide - [x] I confirm I have checked existing issues, online documentation and Troubleshooting guide.
