Describe the issue

When setting up the REHAU Nea Smart 2.0 integration in Home Assistant, a KeyError occurs due to the absence of the "defaultInstall" key in the user object. This prevents the integration from completing its configuration and functioning properly.

Reproduction steps

1.  Add the REHAU Nea Smart 2.0 integration in Home Assistant.
2.  Enter the login credentials.
3.  The configuration fails, and the error is raised.

I've update the file MqttClient.py at line 145 in this:

def set_install_id(self):
        """Set the installation ID based on the user's default installation."""
        default_install = self.user.get("defaultInstall")
        if not default_install:
            raise ValueError("The user does not have a default installation configured.")

        installs = self.user.get("installs")
        if not installs:
            raise ValueError("No installations found for the user.")

        for install in installs:
            if install["unique"] == default_install:
                self.current_installation = {
                    "id": install["_id"],
                    "unique": install["unique"],
                    "hash": install.get("hash"),  # Safe access to 'hash'
                }
                return

        raise ValueError("The default installation was not found among the user's installations.")

Now the error is changed in this:

    raise ValueError("The user does not have a default installation configured.")
ValueError: The user does not have a default installation configured.

hope this help to figuring out, 'cause I do not have any idea about what defaultInstallation is or if I have to do something on my side.

The integration is currently unable to handle cases where the Rehau API doesn't provide a defaultInstall property in the user data.

As a temporary workaround, you can set a default installation in your Rehau app:

Open the Rehau app.
Go to the settings for one of your installations.
Check the box that says "Always use this installation on startup".

This should allow the integration to connect successfully.

I'm aware of this issue and will consider it for a future update.
