Please help. HomeAssistant control voice

Hello guys, sorry for my English.
I installed HomeAssistant on raspberry pi 3 and configured my broadlink rm pro.
I need to know how to start commands using my voice through the smartphone even when I’m out of the house.
For example: I’m out of the house and I want to turn on the air conditioner: “ok google active air conditioning”
it’s possible to do it?
what do I have to do?

sorry, I’m a beginner.

(I know homebridge for homekit apple, but my wife has android)

thank you all

You want the Google Assistant component. This allows you to use Google Assistant on your phone, or Google Home devices, to control your Home Assistant system.
