Others have tackled this problem and created products you could download and use like this or this or this (for the HomeSeer system).

Hopefully, in this post we’ll simplify the approach and present a better way to attack the problem (not in the order we did). It took endless hours of trying this and that. Well, with this as our goal, we set out to figure how to talk to our Sonos. The Sonos system is great, but the album artwork situation is lacking. If this does not work for you, or you see steps missing, please comment below.We’ve had the Sonos system for a while now and we decided that it would be “fun” to create a web application that would talk to the Sonos, get information about what’s playing, and most importantly, match additional album art imagery from a place like to what’s playing. Then click the 'Apply' button for good measure. Choose 'Sonos' under 'Apply predefined player profile'. In the bottom chunk of settings, there should be a drop-down menu defaulting to ''. Click the 'Generate' button, wait 30 secs, reload page and go back to Plugins | UPnP/DLNA bridge settings. Uncheck the 'Running' box and click apply

Click the 'UPnP/DLNA bridge' 'settings' (far right) Upon reloading the Plugins page, you may get a notification that the 'UPnP/DLNA bridge' can be updated. Under Settings | Plugins, ensure that 'Tidal (v2.0)' and 'UPnP/DLNA bridge' are enabled (checkbox). connect LMS8 to (unless already connected) under Settings |. make sure your Sonos device is on, and on the same network as your LMS8 server. add fresh Tidal credentials by clicking 'Log in' under 'Add Another account'. remove Tidal credentials by clicking the 'no-entry' symbol log on to add Tidal App unless already in place It works now, so I wanted to share what works for me. Now that the new Tidal account credentials have been sorted out, I had to wrestle a bit with the bridge config. Not sure if posting there is better or worse than a new thread. The main UPnP bridge thread is pushing 300 pages.
