I currently have 6 Nest devices assigned to an account "email" that was hacked. Can i remove the gmail account from the 6 devices and add a new account? what are my options ?
If you don't have access to the account that set them up, you won't be able to control them using the Google Home app so no, unfortunately. The best thing to do is factory reset them using the physical button on the device and set them up again using a new Gmail account.
