The Groups cluster (0x0004) is a Matter cluster that Enables devices to be organized into groups for coordinated control, allowing a single command to affect multiple devices simultaneously.. It defines 10 commands and 1 attribute and is mandatory for 25 device types.

Code	Name	Direction	Parameters
0x00	AddGroup The AddGroup command allows a client to add group membership in a particular group for the server endpoint.	client→server	`GroupID`: group_id, `GroupName`: char_string
0x00	AddGroupResponse The AddGroupResponse is sent by the Groups cluster server in response to an AddGroup command.	server→client	`Status`: enum8, `GroupID`: group_id
0x01	ViewGroup The ViewGroup command allows a client to request that the server responds with a ViewGroupResponse command containing the name string for a particular group.	client→server	`GroupID`: group_id
0x01	ViewGroupResponse The ViewGroupResponse command is sent by the Groups cluster server in response to a ViewGroup command.	server→client	`Status`: enum8, `GroupID`: group_id, `GroupName`: char_string
0x02	GetGroupMembership The GetGroupMembership command allows a client to inquire about the group membership of the server endpoint, in a number of ways.	client→server	`GroupList`: group_id
0x02	GetGroupMembershipResponse The GetGroupMembershipResponse command is sent by the Groups cluster server in response to a GetGroupMembership command.	server→client	`Capacity`: int8u, `GroupList`: group_id
0x03	RemoveGroup The RemoveGroup command allows a client to request that the server removes the membership for the server endpoint, if any, in a particular group.	client→server	`GroupID`: group_id
0x03	RemoveGroupResponse The RemoveGroupResponse command is generated by the server in response to the receipt of a RemoveGroup command.	server→client	`Status`: enum8, `GroupID`: group_id
0x04	RemoveAllGroups The RemoveAllGroups command allows a client to direct the server to remove all group associations for the server endpoint.	client→server	None
0x05	AddGroupIfIdentifying The AddGroupIfIdentifying command allows a client to add group membership in a particular group for the server endpoint, on condition that the endpoint is identifying itself.	client→server	`GroupID`: group_id, `GroupName`: char_string
