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

[Bhavya Mathukiya]

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,

I saw you created a new ticket here:  Support Needed for Adding Custom Attribute of Struct data type in standard cluster .

Do you wish to continue in the new ticket or this one?

I have replied in the other ticket already, so I will copy my response here:

Can you try changing the type to array and adding RoomSizeCfgStruct as entryType instead? Like this:

<attribute name="RoomSize" side="server" code="0xfff11000" define="ROOM_SIZE" type="array" entryType="RoomSizeCfgStruct" writable="false" optional="false" storage="external">

Here is the full XML with this change:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<configurator>
  <struct apiMaturity="stable" name="RoomSizeCfgStruct">
    <cluster code="0x0406"/> <!-- Occupancy Sensing Cluster -->
    <item name="minMeters" fieldId="1" type="int16u" optional="false"/>
    <item name="maxMeters" fieldId="2" type="int16u" optional="false"/>    
  </struct>
  <clusterExtension code="0x0406">
    <attribute side="server" code="0xfff11004" define="ZONE_OCCUPANCY" type="int16u" writable="true" optional="false" default="0" name="ZoneOccupancy">
      <description>ZoneOccupancy</description>
    </attribute>
    <attribute name="RoomSize" side="server" code="0xfff11000" define="ROOM_SIZE" type="array" entryType="RoomSizeCfgStruct" writable="false" optional="false" storage="external">
      <description>RoomSize</description>      
    </attribute>
  </clusterExtension>
</configurator>

Best regards,
