Great to finally get Alexa integration, but so far all the commands it supports seem to be rather clunky, and occasionally don't work. I have realised since having it the only command I really want is "Alexa Transfer to Sonos everywhere". This would enable me to take the thing that is playing locally and push it to every one of the rooms in my house. Naming rooms is fine when you are looking at them, but is it "Basement", "Office" or "downstairs"?
Added bonus would be to name groups of speakers. Actually the core app could do with this. Otherwise, just need to get the reliability up in the hand over.
The functions should also accept what is playing on my phone's music collection. So "Alexa, play on " should allow you to hear what you have selected on the phone's collection. Not sure if a phone's music collection can be queried in reverse, but it would be nice.
Otherwise keep up the good work! Perhaps you can come up with a command I never knew I needed ;-)!
