Example: My daughter have a speaker upstairs.(Play 1) If she wants some music upstairs in her room, controlled from an iphone downstairs. How Do You know what volume level to play with? Do i really need to walk to every room, to hear each volume level???
My home has levelmeters showed on:
Philips Hue lights have % Light volume
Apple products have volume bars and battery %
Samsung TV's with number volume
...and I can see how fast my car are going:)

...Can You control that little dot in sonos app. with your much larger finger?:) How can You control the music volume in the bathroom, when You have guests, without going into the room???

QUESTION:
Would You like to have the next Sonos App. Updated with volume levelmeter? Bars/Numbers

Kind regards
