+The master instance connects to the Websocket APIs of the secondary instances (already enabled out of box), the connection options are specified via the `host`, `port`, and `secure` configuration parameters. If the secondary instance requires an access token to connect (created on the Profile page), it can be set via the `access_token` parameter. To ignore SSL warnings in secure mode, set the `verify_ssl` parameter to false.
 
 After the connection is completed, the remote states get populated into the master instance.
 The entity ids can optionally be prefixed via the `entity_prefix` parameter.
