Hi,

Your problem is normal. Because it need you to implement this all functions. And this you can read the blog written by Nordic or ask the forum AI to get the answer.

Hi Amanda,

You read the document very carefully. I followed your steps and successfully generated the code and compiled it.

Thanks for your help!

Hi,

The issue is that you copied the .zcl file. The zap-gui script generates a new .zcl file:

Probably your copy of the zcl.json is invalid. Please suggest they remove the zcl.json and call west zap-gui -j src/default_zap/zcl.json --clusters src/default_zap/WaterValveData.xml once again. It should work (at least it works for me).

Also, please ensure to run west update to have a proper sdk-connectedhomeip revision.

Regards,
Amanda H.
