A deviceId is now available in the JSON information sent to the Lambda function. This allows you to have separate defaults for each Echo device for the Room and Music Service. Basically you can associate an Echo device with a specific Sonos device and not have to say "in the " after the first time. So an Echo in the kitchen can always control the Kitchen Sonos (unless you change it again), and an Echo in the Den will alway control the Den Sonos, etc..
