How many Nest Thermostats?

There is no limit in Alarm.com 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 Alarm.com account? To do so:

  1. Log into the Alarm.com 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.
