''flow_grouprempty: <group id>''

Allows you to empty a group within the show flow directly from code - as opposed to the data being manually entered via a remote interface. 
  * **group id** is the group id of the group to be emptied- you would normally use a variable reference to ''zone.groupid'' here.

**Please use this command with care - it is irreversible short of a [[commands:backup_restore_commands|full flow restore]].**
