I just picked up a Google Nest Mini, and was hoping to connect it to Smartthings to control the lights in my Media Room. When I try to connect the 2, I keep getting this message.
You should be able to integrate Google Home through the mobile application. In the new app. Press the + sign in the top right corner and click on Voice Assistant, the it should bring you to the right page.
I got it sorted out. I had 2 emails linked to Smartthings, one was a Yahoo, and the other Gmail. When I logged into Smartthings with the Gmail account, then it linked.
