I just migrated over my nest doorbell and thermostat to google home app and had to set up a different gmail account to do that and now have 2 accounts on my home app. Wondering how I can get it all under one account as my nest mesh wifi is under the other account and shows up as local devices on the new account. I was on hold for hours to get the migration over and not sure I have it in me to wait for that service to figure this out.

I understand the hesitation to reset the devices and set them up once more. Unfortunately resetting them (factory reset) would be the only way to fully get them transferred over to the single account. But since settings are saved on the Home app, you'll only need to run setup on the devices, not the entire network. If you have any issues setting things up, please let me know.
