I have nine Sonos speakers in my home and I would dearly love to be able to create the equivalent of Philips Hues lighting “scenes” as presets for different listening situations. Saturday morning crank it up? Hit one preset and all the speakers move to pre-assigned volume levels per speaker for that situation. Sunday afternoon background jazz while I’m reading? Hit another group pre-set. TV watching? Another. And so on. I can’t tell you what a difference this would make. I’m constantly re-setting volume levels all over the place depending on needs and variances in input normalizations. Thanks for considering this.
