Home Assistant Home Assistant

Somfy

The Somfy integration will allow users to integrate their Somfy devices into Home Assistant using the official API, unlike the Tahoma integration.

Installation

Somfy is leveraging the new account linking service. This means that to set up Somfy, you only need to go to the integrations page and click on add new integration.

Installation with own developer account

It is possible to create your own developer account and configure Somfy via that.

Setting up developer account

  1. Visit https://developer.somfy.com.
  2. Log in using your Somfy credentials.
  3. Open the My Apps menu.
  4. Add a new App:
  • App Name: Home Assistant
  • Callback URL: <YOUR_HOME_ASSISTANT_URL>/auth/external/callback
  • Description: Home Assistant instance
  • Product: Somfy Open API

Pre-configuration

# Example configuration.yaml entry
somfy:
  client_id: CONSUMER_KEY
  client_secret: CONSUMER_SECRET

Configuration Variables

client_id string Required

Your Somfy consumer key.

client_secret string Required

Your Somfy consumer secret.

optimistic boolean (Optional, default: false)

Set optimistic mode.

optimistic mode should only be used when the integration is not able to gain information on whether a cover is open or closed (e.g., RTS devices). It will attempt to track the status within Home Assistant. This mode should only be used if Home Assistant is the only way you operate the blind. If you also use the physical remote control or the Somfy app, Home Assistant will become out of sync.

Configuration

Adding Somfy to your Home Assistant instance can be done via the user interface, by using this My button:

Somfy can be auto-discovered by Home Assistant. If an instance was found, it will be shown as “Discovered”, which you can select to set it up right away.

Manual configuration steps

Potential duplicate with the Tahoma integration

If you use the Tahoma integration, you will have to exclude the covers added by this one. Otherwise, they will be added twice.

# Example configuration.yaml entry
tahoma:
  username: YOUR_USERNAME
  password: YOUR_PASSWORD
  exclude:
