Matter: How to add custom attributes and commands into the standard cluster (ex: occupancy cluster server)

Dear Team,

I would like to know if it is possible to add custom attributes and commands to standard clusters, such as the Occupancy cluster. I have reviewed the "Adding a Custom Cluster" guide provided by Nordic, but I am unsure how to proceed with modifying standard clusters.

Could you please advise if this is feasible and, if so, provide some guidance on how to implement it?

Best regards,
Bhavya

  • Hi Bhavya, 

    I will investigate if it is allowed by the Matter specification to add attributes/commands which are not included in the cluster definition. I suggest that you also check this if you are able to. 

    I assume you are using the latest nRF Connect SDK release (v3.0.2)? This is important to refer to the correct version of the Matter specification(s). If you are using nRF Connect SDK, the Matter v1.4 specification is the correct version. 

    Best regards,
