I have created a new applet in IFTTT. In short, it is triggered by a webhook and then it plays a favourite track on my Sonos system. It works great as long as I choose 'include all rooms' and my favorite starts playing. But when I choose 'this room only' nothing happens.
I would like to play the song on an Ikea Symfonisk, but the result is same when I try on my Sonos One or my beam
