The Nest Community is now Google Home & Nest!
We have moved to a new home. Please visit the Google Home & Nest Community to connect with other users, ask questions, and explore the new space.
No need to create a new home. In the Google Home app, go to settings,
then go to “Rooms and Groups”. From this list you can select the group
with the disconnected device, find it and delete.
