Melissa climate integration problem

After inserting this text to configuration.yaml

  password: YOUR_PASSWORD

Nothing changed,when i try to add integration, i receive the same error
This device cannot be added from the UI
You can add this device by adding it to your ‘configuration.yaml’. See the documentation for more information.
What do i miss?

For yaml configured integrations you need to restart home assistant.

When you do, the integration will either show up as a climate entity, which you can see in developer-tools/states, or it will generate errors in your logs.
