Honeywell Lyric

The Honeywell Lyric integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] integrates the Lyric thermostat platform into Home Assistant.

Setup

To set up this integration, you first must set up a developer account with Honeywell using the same email address as your Resideo account:

  1. Go to the developer site and register with an account.
  2. Next, create a new app via the My Apps section.
    1. App Name: You can use any name here, but it must not contain special characters.
    2. Callback URL: https://my.home-assistant.io/redirect/oauth
    3. The app will be approved automatically. To view the Consumer Key and Consumer Secret values, select the name of the app. Copy the values, you will need them later.
I have manually disabled My Home Assistant

If you don’t have My Home Assistant on your installation, you can use <HOME_ASSISTANT_URL>/auth/external/callback as the redirect URI instead.

The <HOME_ASSISTANT_URL> must be the same as used during the configuration/ authentication process.

Internal examples: http://192.168.0.2:8123/auth/external/callback, http://homeassistant.local:8123/auth/external/callback.”

You can then add the integration in Home Assistant.

Configuration

To add the Honeywell Lyric hub to your Home Assistant instance, use this My button:

Honeywell Lyric can be auto-discovered by Home Assistant. If an instance was found, it will be shown as Discovered. You can then set it up right away.

Manual configuration steps

If it wasn’t discovered automatically, don’t worry! You can set up a manual integration entry:

  • Browse to your Home Assistant instance.

  • Go to Settings > Devices & services.

  • In the bottom right corner, select the Add Integration button.

  • From the list, select Honeywell Lyric.

  • Follow the instructions on screen to complete the setup.

The integration setup will ask for the Client ID and Client Secret. These correspond to the Consumer Key and Consumer Secret values from the app you created on the Honeywell developer site. See Application Credentials for more details.

Important

During setup, you will be redirected to Honeywell to sign in. Use your regular Resideo/Honeywell Home account here, not the developer account you created on the developer site. These are two separate accounts, even if they share the same email address.
