Thanks for posting here in the Google Nest Community.
I know how it feels when something isn’t working as it should, let’s get this resolved. A few thing: could you tell us more about what's happening on your Nest speaker? Is it not responding to your command or not powering on?
Keep me posted.
We haven’t heard back from you, I'll be locking this thread in 24 hours. Feel free to create a new one if you have more questions or have other concerns in the future.
