Hi Folks.
Complete HA Noob here so please forgive me if what I’m asking is really obvious! 
I am looking to control my Hitachi air-con (with air cloud) via Home Assistant when certain other conditions monitored by Home Assistant are met. I can’t find a direct integration but the Hitachi is supposedly able to be controlled by Google Home/Amazon Echo. From what I can tell, the Google Assistant SDK will allow me to send txt commands to a Google Home device to tell it to do things like turn the aircon on.
I can’t see any equivalent for the Amazon universe. I can find tools for controlling your HA by voice from Google/Amazon but I’m trying to go the other way.
Is there an Amazon equivalent that I haven’t spotted yet or should I just head down the Google path?
Many Thanks
