Please tell me if this is already possible, but I think it would make sense in this example situation:
Some company made a smart light for $5 but they don’t work with HA at the moment, but they work with Google Assistant. So you can do an automation in HA that uses the Google Assistant API, so when you press a button in lovelace for example, it will tell Google Assistant to “turn on the light”
You could literally make HA do anything Google assistant can do.
Here’s another example automation:
- alias: 'Leave Home notification'
message: 'Paulus left the house'
I’m not a programmer, but I have seen many other projects of people doing things like making DIY google speakers
