How Do I Add a Google Nest Thermostat to My Alarm.com Account?

You can add a Google Nest Thermostat to your Alarm.com account by providing your Google account information to Alarm.com. The integration allows for limited thermostat functionality through Alarm.com, including temperature control, mode control (Heat, Cool), and scene thermostat control.

Many users choose Google Nest Thermostats for their ability to integrate with the Alarm.com platform. While using a Z-Wave Thermostat, such as the Alarm.com ADC-T3000, is usually our recommended option, the Google Nest integration is still a nice way to achieve temperature and mode control through Alarm.com. The integration has been supported by Alarm.com for quite some time. However, the integration was made unavailable for an extended period of time, starting in August of 2019. But in January of 2020, the integration returned, and it once again became possible to integrate a Google Nest Thermostat in with an Alarm.com account. If you have an Alarm.com Security System and a Google Nest Thermostat, then completing this integration process is something you will likely want to do.

Before getting started, there are a couple of things to keep in mind. First, you must have the Nest Integration add-on applied to your Alarm.com account. This can only be done by your alarm monitoring company. You should contact your monitoring company and ask them to apply the integration to your account. If you are an Alarm Grid monitored customer, then you can contact us by emailing support@alarmgrid.com. Second, if you have a Nest Thermostat that was previously integrated with your Alarm.com account, and you are now trying to re-integrate it, then you may need to first access your Nest account and remove the existing ADC integration. You will then be able to move your Nest account to Google. If you fail to remove the integration, you may encounter an error stating that you have a "Works with Nest" option assigned to your Nest device. Only once your Nest Thermostat is integrated with your Google account will you be able to integrate the device with Alarm.com. Make sure you have integrated your Nest Thermostat with your Google account first.

Remember, the Alarm.com integration for Nest Thermostats is rather limited. You will still need to use the Nest platform for any thermostat scheduling. The Alarm.com integration just offers a quick way to adjust the temperature, set the desired mode (Heat, Cool), and perform basic scene thermostat control for temperature and mode adjustments. It is also important to note that Alarm.com will display a Nest Thermostat as OFF when the device is in its Eco mode. You can exit Eco mode for a Nest Thermostat from Alarm.com by setting the thermostat's mode to Heat, Cool, or Auto. Alarm.com allows for Nest Thermostat control from both the Alarm.com website and mobile app.

For this FAQ, we will assume that you have already successfully integrated your Nest Thermostat with your Google account and that the Nest Integration add-on has been applied to your Alarm.com account by your monitoring company. Complete the following steps to add your Google Nest Thermostat to your Alarm.com account:

1. Login to ADC website. The process of integrating a Nest Thermostat with Alarm.com must be completed from the Alarm.com website. It cannot be completed using the Alarm.com Mobile App. Open Alarm.com in a web browser, and provide your credentials (username & password) to login to your Alarm.com account.

2. Add a Nest Thermostat. Click on Settings on the left side of the screen. Then choose Add Device. This option will only appear if you have at least one compatible integration add-on applied to your Alarm.com account.

Next, select Thermostat, followed by Google Nest Learning Thermostat. Then choose Begin Installation on the following screen.

3. Provide Google account information. You must provide the account information for the Google account associated with your Nest Thermostat to complete the integration. You will need to provide your Google username and password. This will provide authorization for Alarm.com to access your Google account, which is necessary for controlling your Nest Thermostat through Alarm.com. Please note that it may take a few minutes for the authorization process to complete so that you can begin controlling your thermostat through Alarm.com.
