Beginner Question HTTP GET

Hello, I am running openHAB 3.4.2 on a Windows 10 machine and I am trying to trigger a “lights off” command with Cinemavision (Kodi) using this approach:

I have my light switch set up as an item and can turn it on and off from the items screen in openHAB but I can’t seem to figure out how to get it to turn on as an HTTP request like in the above example.

I am very new to openHAB so I am sure that I am missing something pretty obvious here. Can anyone point me in the right direction, perhaps to a tutorial that might help me get this going? I know Cinemavision is pretty outdated, but my setup still works perfectly except for executing this action. Any help is greatly appreciated!

openhab does not officially support http/get to trigger items, only htp/post.
In case you cannot use http/post I suggest the following options:

  1. official way
    use this binding
    this binding is not released. You have to install it yourself. I am also using it and it just works great

  2. inofficial way
    use this http/get request:


You have to install BasicUI and be aware that this hack may be dropped any time without any prior notice as it is an unsupported feature are a feature used for something elase but to trigger items from 3rd party devices.
