Simple http plug setup - guide needed

Hi All, I have setup openHab 2 on rasp pi and I’m a total newbie in openHab.

I’ve a http plug that I can turn it on / off with simple browser command such as the below. I want this plug to appear as as switch / plug in the Pepper UI, is that possible? Should I use http binding? Which file (and location) that I need to edit manually (the Gui way of setup seems not working / broken), a sample setup of the file will be very much appreciated.

I also read the http binding doc but as a newbie I’m lost, forgive me :wink:

To turn on:
http:///on
or to turn off:
http:///off

A good idea to start is with https://docs.openhab.org/v2.1/tutorials/demo.html

Yes, you need the HTTP-binding https://docs.openhab.org/addons/bindings/http1/readme.html
and write your item-definition in a items-file. https://docs.openhab.org/tutorials/beginner/

There are many tutorials at YouTube like this https://www.youtube.com/watch?v=MV2a5qwtmRE
