If you have a Samsung Tizen Smart TV with a model after 2015 there's a put.io app for it! You can search for "put.io" in the Tizen app store and start using it. 

When you first load it, it will ask you to visit https://put.io/link and enter the code shown on the TV. After doing that it will be able to access your content at put.io.

You can also use the same interface from other smart TV's by visiting https://tv.put.io from the TV's browser. 
​
​P.S. Good news! We are working on a new Samsung TV app and with this we aim to make the streaming experience better for you guys!
