We should have voluptuous schemas for data. That way any vulnerability in hassio won't be exposed. There was a problem hiding this comment. Choose a reason for hiding this commentThe reason will be displayed to describe this comment to others. Learn more. I think we make only a passthrought. HassIO will give a error back to frontend if a option will not support it. |
