My son gave me a Google Home Mini for Father's Day. I have just written a very simple Hubitat Driver that is able to issue custom broadcasts to the google assistant relay node js server.
It supports both the Speech Synthesis and Notification capabilities.
This should allow standard Hubitat apps to send google home broadcast messages to your devices. I know webCoRE can do this as well, but I am trying to keep my Hubitat hub as simple as possible. So, I am using Rule Machine for most of my automations.
Details are in this new post
