You can refer to ZCL specification to read window covering cluster/CurrentPosition – Lift /Tilt attributes to know the position. However, those two attributes are optional and might not be implemented by manufacturer.

Do you try to refer to ZCL specification to read window covering cluster/CurrentPosition – Lift /Tilt attributes to know the position?

Hi Praveen,

The first three bytes are the header: 0x08 is frame control, 0x41 is transmission sequence number, 0x0A is the command ID which is ZCL_CMD_REPORT indicating an incoming report. According to the ZCL Specification that YK keeps referring to, next is the Attribute identifier (0x0008 or ATTRID_WINDOW_COVERING_CURRENT_POSITION_LIFT_PERCENTAGE), data type (0x20 or ZCL_DATATYPE_UINT8), and the data (0x00 the first time and 0x0A the second. Two attributes must be reported, what follows is the second: attribute identifier 0xF000, data type 0x30, and data 0x00 or 0x01.

Regards,
Ryan
