It isn't bluetooth, but wifi-direct remote. Any universal remote with roku listed will control your roku premiere plus, because it also accepts IR remotes. Roku doesn't sell universal remotes, it has wifi remote with tv controls, and only roku wifi remotes have tv controls, regular IR roku remote do not. Look for the Roku Voice remote for $19.99 here:

I see its on backorder, you can get the same remote at walmart or best buy. Its $19.88 at walmart, where its $29.99 at best buy.
