FAQs

Adding a second Nest Thermostat or Protect?

If you're adding a second Nest product then you must re-log in to Nest in order to grant additional permissions for Harmony to interact with the new device.

Does Harmony support multiple Nest Thermostats?

Yes. Harmony will communicate with as many Nest Thermostats as you have in your Nest account. Each thermostat will appear as a different device 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 the Harmony hub nor our Harmony servers store 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. After signing in, Harmony will save a unique permission key that allows us to continue communicating with your Nest device.

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.

Harmony displays an authentication error and can no longer control Nest.

How does Harmony help extend Nest's auto-away sensing capabilities?

Is your Nest Thermostat are in areas of your home that may not detect presence if you're watching TV for a long time? Every time you pick up your Ultimate or Ultimate Home remote, Harmony will notify Nest that someone's present to prevent it from entering auto-away mode. If Nest is already away, Harmony will prompt you to confirm End Auto-Away.

To disable Harmony from notifying Nest of your presence:

  1. Using your Harmony remote, navigate to your Nest control panel.
  2. Scroll down and select Turn Off Away.
  3. Select either ENABLED or DISABLED and press the  < (back) button to exit.

Harmony 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 Ultimate Home remote lists each of your Nest Thermostats within the DEVICE MENU. You may re-order any of these devices by selecting MENU, then EDIT and then dragging the device to a new order position.

Harmony Ultimate places the Nest Thermostat control panel at the bottom of the Activity home screen and does not allow for it to be re-positioned.

How Harmony controls Nest

All Harmony hub based products

Harmony communicates with the Nest Home cloud using your Wi-Fi network. Nest and Harmony require a constant internet connection in order for them to communicate with one another.

All other Harmony products

As Nest Thermostat does not accept infrared (IR) commands, Harmony remotes that do not come with a Wi-Fi enabled Harmony hub will be unable to control it.
