If you have deck hardware (like the streamdeck) or are using another deck app (check out https://obsproject.com/forum/resources/ for other options), but you still want to use some UP Deck features then you can use the UP Deck desktop app with your deck of choice...

First read Assigning_actions_to_buttons - then set up a deck and buttons to perform the required actions.  You can then remotely push the buttons by calling the 'xdeck' url - just program your deck app or hardware to access a web page.

Example - press button 10 in the deck named 'streamdeck'. (You can test by entering the url into your browser)

http://127.0.0.1:10314/xdeck/streamdeck/10

Note : your deck software / hardware must be running on the same machine as the UP Deck desktop app.
