With the Google Home app you can’t assign scenes to rooms. For my puprose I have a room called “Roomless” in my Google Home app to organize the scenes. I noticed that new scense weren’t being assigned to a room after you sync. This didn’t bother me until I realized my wife couldn’t access scenes from her Google Home app for routines etc unless they were in a room. I couldn’t find much recenet information regarding this or my Google-Fu was failing me.
It’s crap solution but I did find that if you unlink and then re-link SmartThings to Google Home it will allow you to assign the scenes to rooms. It’s a drag with 65 “devices” but it’s a solution that works.
Had anyone found a better way to do this?
