It’s silly we have to do these things isn’t it? Unless someone can point me to a setting, I’m unaware of a way to lower ( I don’t mean do not disturb mode) the volume on Google Home by schedule. So I have my Echo sitting next to my GH mini telling it to lower and raise the volume on a schedule. 
And if you want to see a wired workflow (that works brilliantly by the way), to force Google, Amazon, and Samsung to work together for Hubitat’s benefit, look no further
