How to configure Harmony to control Nest

Each Harmony Activity can trigger a different temperature setting, as well as adjust your heat, cool, heat-cool or off thermostat modes. For example, when starting Watch TV you can warm your home up a little bit, while selecting Listen to Music turns off your A/C, or does nothing at all.

To configure your temperature settings to an Activity:

  1. Open the Nest control panel from the Activity home screen.
  2. Scroll down and select Program.
  3. Choose the Activity for which you'd like to associate a temperature setting.
  4. Adjust your Nest mode and temperature values and then click Set.
Activity Program

Now, the next time you launch this Activity from either your remote or the Harmony smartphone app, your Nest thermostat will automatically adjust your home temperature.

If you'd like to clear any pre-defined temperature and Activity settings, follow the same steps and select Clear instead of Set on the final screen.

Why can't I control Nest from my Harmony App?

Nest is currently exclusive to the Harmony Ultimate remote and does not work with other Harmony products. If you've configured a Harmony Activity to automatically change your temperature, then launching an Activity from either the remote or the app will trigger Nest to change your thermostat. Harmony App does not permit direct temperature control.

Does Harmony Ultimate support multiple Nest Learning Thermostats?

Yes. Harmony will pair as many Nest Learning Thermostats as you have in your Nest account. Each thermostat will appear as a different button on your Activity home screen, and each one may be controlled or associated with an Activity independent of the others. If you have the end auto-away feature enabled on your Harmony, then all thermostats in your home will be notified when you're using your remote..

If you have multiple home locations with one or more thermostat in each building, Harmony will prompt you to select a single home when you are pairing with Nest..

What security information does Harmony store?

Neither your Harmony remote and hub, nor our Harmony servers store any Nest username or password credentials. During authentication you are taken to a Nest webpage that allows you to enter your Nest credentials; however Harmony never sees this information.

Harmony does not track when you are home or away, nor do we track any temperature changes you make. Logitech Harmony respects your privacy. Read more about our privacy and security statement.

My remote displays an authentication error and can no longer control Nest.

If you've factory reset your Harmony Hub, or if you've de-authorized Logitech Harmony from the Nest website or app, then you must re-pair Harmony Ultimate and Nest.

Using the Harmony smartphone app:

  1. Select Menu > Settings > Edit devices and Activities > Devices.
  2. Select the Home Control tab, select Nest and press the Refresh button.
  3. This will open a Nest authentication window allowing you to re-enter your password.

You may also enter your new Nest credentials using the MyHarmony desktop software.

  1. Plug your Harmony Ultimate remote into your computer using the supplied USB cable.
  2. Sign in to the MyHarmony desktop software.
  3. Select your remote from the remote gallery.
  4. Select the Devices tab on the left, then the Home Control tab on the top.
  5. Select your Nest Thermostat and press the Refresh/ Re-login button.

How do I remove my Nest Learning Thermostat from my Harmony account?

Using the Harmony smartphone app:

  1. Select Menu > Settings > Edit devices and Activities > Devices.
  2. Select the Home Control tab, select Nest and press the Remove button.

You may also remove Nest using the MyHarmony desktop software.

  1. Plug your Harmony Ultimate remote into your computer using the supplied USB cable.
  2. Sign in to the MyHarmony desktop software.
  3. Select your remote from the remote gallery.
  4. Select the Devices tab on the left, then the Home Control tab on the top.
  5. Select your Nest Thermostat and press the Delete button.

Can Harmony control a Nest that has been locked?

Nest Learning Thermostats allow you to set a 4 digit pin so that it can only be adjusted within a certain temperature range. Learn more. Harmony also respects this range and will not allow someone in your home to change the thermostat too warm or too cool if that lock has been set.

Changing your temperature outside of the lock limits from your Harmony Ultimate remote will update the temperature on the remote, but not on your thermostat causing your remote to become out of sync with Nest. To correct this, change the temperature from either your thermostat or from the Nest app, or select the Refresh button from the Nest control panel on your Harmony remote.

How does Harmony Ultimate help extend the auto-away sensor in my Nest?

Is your Nest thermostat in an area of your house that may not detect your presence if you're watching TV for a long time? Every time you pick up your remote, Harmony will notify Nest that someone's home to prevent your thermostat from entering auto-away mode. Harmony will first prompt you to confirm End Auto-Away or not before notifying Nest.

To disable this feature:

  1. Using your Harmony remote, select the Nest button from your Activity home screen.
  2. Scroll down and select Turn Off Away.
  3. Select either Enabled or Disabled and press the  < (back) button to exit.
Nest Auto-Away

My remote displays a "trouble communication error" when I try to control Nest.

This dialogue may appear if your Harmony Hub is unable to reach the Nest Home cloud.

  1. Check your Wi-Fi and internet connections.
  2. Try powering off all of your Harmony Activities, then disconnect and reconnect the power to your Harmony Hub. It will take 30 seconds to power on again.
  3. Try rebooting your Harmony remote by holding the Off button for 15 seconds.

Temperature changes made on Harmony are not appearing on Nest.

Nest prevents devices such as Harmony from updating your thermostat temperature more than 10 times an hour. If you exceed this limit then Nest will reject any additional temperature changes and Harmony will display the previous temperature setting after several seconds. Waiting an hour will automatically reset this limit.

If you Harmony is still unable to control Nest, then we recommend re-authenticating Harmony and Nest. Learn more.

Can I re-order the Nest button on my home screen?

The Nest button is fixed to the bottom of your Activity home screen and cannot be re-ordered.
