This is the subject of a few forums and many suggestions, but I haven’t been able to find a solution (including from Sonos Customer Support).
In short, I have a network of Sonos One units for which I want to control individual unit volumes using percentage settings from Alexa. Standard Alexa only allows 10 volume increments, so using the Sonos skill does not work. The Sonos devices have a wide and very good range of volume and adjusting them effectively by 10% at a time is hopeless.
For years I used Yonomi via Alexa, which used the Sonos API and that worked perfectly. Unfortunately, they went under.
So I then subscribed to IFTTT, which also worked well … and then Alexa withdrew its support of IFTT.
There are several solutions set up to use the Sonos API, but all the ones I have found require the setting up of a hub. I don’t want to have to have a PC or Raspberry PI device just to control my music system volumes!
Is anyone aware of a hubless Alexa option? (Preferably free, but perhaps that’s a forlorn hope!)
