SEE or Websocket to access local and/or remote instance?

I’m having a hellof a time getting anything but the normal rest call to work. I’m using OH2 and I’m trying to get updates from the server but nothing seems to be working. I’m assuming I don’t have to install anything extra? Do the same commands work for or only on the actualy openhab server?

I also don’t see anything in the logs, do I have to enable a certain package logging?
