How many Nest Thermostats?

How many Nest thermostats can the app support?. I have 4 of them but only 2 show in my app

There is no limit in for Nest Thermostats but there is a hard limit of 20 per google account.

Currently I am only seeing two tied to your account. Have you gone through the necessary steps to pair the other two with your account? To do so:

  1. Log into the Website.
  2. Click Settings .
  3. Click Add Device.
  4. Click Thermostat.
  5. Click Google Nest Learning Thermostat.
  6. Click Begin Installation .
  7. Enter the primary Google account login information.

Yes, that is exactly what I have done and then I get an error. See below

You can only associate one Google account with your account. Are all 4 devices associated with the same Google Account ?

I can view them all in the nest app

When did you add those two additional thermostats to the Nest app?

I’ve tried running an equipment check but no additional devices are reported by Nest.

Are the ones not showing up older or newer than the two there now?

can you delete all of the thermostats and i will start over?

No problem. They’ve all been deleted.

Thanks, I deleted them from my nest account too. 3 of 4 show up in the app now. The 4th one is having an issue so its not being used at the moment but I will try to add it back soon

I have the 4th thermostat connected again and linked to my nest account.

Can you please delete again as I’m not able to see or add any of them?

It looks like there was indeed an error with the ADC-Nest sync here. Your account was reporting on the back-end as though no account sync was in place.

You should be able to go into now and re-add your Nest account. Success?

Thank you. Yes, all 4 now show up in the Alarm app.

Excellent! I can confirm that all four are reporting on the back end as well.
