Hello,

We want to define a custom attribute for cluster QAPI_ZB_CL_CLUSTER_ID_COLOR_CONTROL.

we have performed following steps:

1)  Defined custom attribute in zcl_colorcontrol_demo.h file
#define QAPI_ZB_CL_COLORCONTROL_ATTR_ID_CUSTOM_XYZ 0xFFFE

2) Added this attribute list with capabilities to attribute list as below

static const qapi_ZB_CL_Attribute_t ColorControlDemoCustomAttrList[] =
{
{ QAPI_ZB_CL_COLORCONTROL_ATTR_ID_CURRENT_HUE, QAPI_ZB_CL_ATTRIBUTE_FLAG_REPORTABLE | QAPI_ZB_CL_ATTRIBUTE_FLAG_CUSTOM_READ_WRITE, QAPI_ZB_CL_DATA_TYPE_UNSIGNED_8BIT_INTEGER_E, sizeof(uint8_t), 0, 0, 0, 0xFE },
{ QAPI_ZB_CL_COLORCONTROL_ATTR_ID_CURRENT_SATURATION, QAPI_ZB_CL_ATTRIBUTE_FLAG_REPORTABLE | QAPI_ZB_CL_ATTRIBUTE_FLAG_CUSTOM_READ_WRITE, QAPI_ZB_CL_DATA_TYPE_UNSIGNED_8BIT_INTEGER_E, sizeof(uint8_t), 0, 0, 0, 0xFE },
{ QAPI_ZB_CL_COLORCONTROL_ATTR_ID_ENHANCED_CURRENT_HUE, QAPI_ZB_CL_ATTRIBUTE_FLAG_REPORTABLE | QAPI_ZB_CL_ATTRIBUTE_FLAG_CUSTOM_READ_WRITE, QAPI_ZB_CL_DATA_TYPE_UNSIGNED_16BIT_INTEGER_E, sizeof(uint16_t), 0, 0, 0, 0xFFFF },
{ QAPI_ZB_CL_COLORCONTROL_ATTR_ID_CURRENT_X, QAPI_ZB_CL_ATTRIBUTE_FLAG_REPORTABLE | QAPI_ZB_CL_ATTRIBUTE_FLAG_CUSTOM_READ_WRITE, QAPI_ZB_CL_DATA_TYPE_UNSIGNED_16BIT_INTEGER_E, sizeof(uint16_t), 0, 0, 0, 0xFEFF },
{ QAPI_ZB_CL_COLORCONTROL_ATTR_ID_CURRENT_Y, QAPI_ZB_CL_ATTRIBUTE_FLAG_REPORTABLE | QAPI_ZB_CL_ATTRIBUTE_FLAG_CUSTOM_READ_WRITE, QAPI_ZB_CL_DATA_TYPE_UNSIGNED_16BIT_INTEGER_E, sizeof(uint16_t), 0, 0, 0, 0xFEFF },
{ QAPI_ZB_CL_COLORCONTROL_ATTR_ID_COLOR_TEMP_MIREDS, QAPI_ZB_CL_ATTRIBUTE_FLAG_REPORTABLE | QAPI_ZB_CL_ATTRIBUTE_FLAG_CUSTOM_READ_WRITE, QAPI_ZB_CL_DATA_TYPE_UNSIGNED_16BIT_INTEGER_E, sizeof(uint16_t), 0, 0, 0, 0xFEFF },
{ QAPI_ZB_CL_COLORCONTROL_ATTR_ID_CUSTOM_XYZ , QAPI_ZB_CL_ATTRIBUTE_FLAG_REPORTABLE | QAPI_ZB_CL_ATTRIBUTE_FLAG_CUSTOM_READ_WRITE, QAPI_ZB_CL_DATA_TYPE_UNSIGNED_8BIT_INTEGER_E, sizeof(uint8_t), 0, 0, 0, 0xFE }};
 
 
 
 
Now the problem we are facing is if we send command to change hue and sat its working. 
If we send command 0xFB for QAPI_ZB_CL_COLORCONTROL_ATTR_ID_CUSTOM_XYZ attribute it shows unsupported cluster on sniffer as default response. and no callback is hit for color control.
 
What additional step i need to perform to make it work?
 
Thank you,
