Help walk me through my first automation

I installed the Samsung TV add-on. OH2 found the TV and put it in my Inbox. I then created an item to control volume and power. When I go to the Control panel, I can successfully control the volume but the power switch doesn’t do anything. What should I check? Thanks

Sorry to report, power may not be supported. Review the Channels section of the following binding page.

Thanks @Toneus. It must be my model doesn’t support that.

Mine doesn’t either, which is the reason I knew about that comment.
