KeyError: 'site_name' - Can't configure component when site has no name specified

Version of the custom_component

1.1.0

Configuration

Describe the bug

When attempting to configure the integration it fails with this (and yes I put the correct token in the window):

I only have a solar system (no car), I think it’s related to this: https://github.com/alandtse/tesla/pull/58. Maybe @giachello knows what’s going on?

It works perfectly, thanks!

Just wanted to add a comment:

1. This bug is encountered even if you have vehicles, if you have a Solar system
2. Definitely because the default name of your home is “My Home”, and it must be returning NULL instead of “My Home”
3. Tapping on the name “My Home” in the Tesla app will allow you to change the name (while viewing your Solar)

Once the name is changed, this error disappears in the integration.
