I have Google home but the concept is the same. I have 4 Chromecast audios in the rack. Named inside, outside, master bath, and garage. Then in programing of the matrix amp you can trigger when audio is present to turn a desired zone on and off. It works great, biggest downfall of using a Chromecast or echo is no metadata compared to using a Sonos connect or port. But a vast improvement over native music for voice control at the moment.
