Not sure if this was previously discussed, but I just stumbled onto something pretty cool for those with Echo Show devices. If you use the Roon Web Controller extension (mine is installed on Dietpi), you can bookmark the Amazon Silk and/or Firefox browsers on your Echo Show devices and it will show what’s playing, including play/pause/skip, etc. commands. Just say “Alexa, open Silk” or “Alexa, open Firefox” and it will show what’s playing on Roon (assuming the IP is already defined in the browser). Sometimes I have to click on the bookmark if not still loaded (there are browser config options on the Echo Show). It’s a nice additional way to get a display for Roon and control it too.
I also created bookmarks on my LG smart TV web browsers to do the same thing as another way to show what’s playing on Roon (instead of having to rely on a Chromecast). Just bring up the WebOS menu and click on the browser and it shows it (otherwise click on saved bookmark to load it).
Doesn’t work quite as well on Fire HD tablets that can also be used as an Echo Show device (YMMV). For that it’s best to stick with the official Roon or Sonos apps.
