title: Trigger Google Home listening with pysical button maybe via network from a Raspberry Pi/Ardruino/etc
body: <p>I need to trigger the google asistant on my google home (mini) by using a physical button.
  I was thinking it may would work by using a Pi or something like that and then pingin it via some api or by creating a addon for the assistan ( i forgot what they are called right now).
  Someone got any ideas how i could get this to work?</p>
