+For environments where there are multiple sites setup on the controller, or the default site is not being used you can use the `site_id` parameter to specify which site you would like to target.
+
+Please note that the value that is to be specificed here is not the name of the site as you would see it in controller interface, but a site ID value assigned from the software itself.
+
+To obtain this value for your configuration file, you can take it from the URL of your browser when on the controller webpage.
+
+For example, this is what would be seen in the URL bar when inside the dashboard page of a site:
+
+* https://127.0.0.1:8443/manage/s/ceb1m27d/dashboard
+
+And your `site_id` value would be ceb1m27d.
