Sunday
I created a very simple automation to turn one light on a specific color and brightness. I can turn this automation on through the app, and I have the setting chosen to start the automation when I say a key phrase to Google, but when I say these phrases to the speaker, it doesn't know what I'm talking about. I'm hoping to make this work soon as I have a baby coming and the automation is for late night diaper changes and feedings. It would just be helpful.

Have you reconnected the manufacturer's app to the Google Home app? Settings > Works with Google.
