Error calculating costs with Tibber provider

[JonasF1]

Hi, Have used this excellent app with my Teslamate installation. But now it does not work anymore. Stopped working 3-4 weeks ago. Get following error on my docker instants when using the Tibber provider.

Hi, I'm seeing the same thing on my end for any call to Tibber's API for all requests right now so I am guessing either they've changed the API without documenting it or they're having some issues right now. I'd recommend contacting their support for more information. You can tell them that the Data.Viewer.Homes[0].CurrentSubscription is null in their GraphQL API response which may help them.

Hi, Did as you suggested. Contacted the Tibber support. They seems to have fixed the issue now! Now I get price info on my charges. :) Thanks for excellent application.
