Our Nest Hubs often perform a reboot around 3 or 4 am, because that's when Google Nest's servers push out updates. I don't know if it happens every night. A couple of times I've seen the reboot occur; on ours, the display remains very dim, and I don't hear anything.

Hi everyone,

Thanks for sharing that information, MpIsCustomer.

Mersafe, let’s further look into this. When did you first notice this behavior? Were there any recent changes you made in the Google Home app or your Google Nest Audio device’s settings prior to this behavior? Are you using private or shared Wi-Fi? Have you tried to reboot or factory reset your Google Nest Audio device?

Regards,
Alex
