+The master instance connects to the Websocket APIs of the slaves, the connection options are specified via the `host`, `port`, and `secure` configuration parameters. An API password can also be set via `api_password`. 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.
