In the red card, it mentions state. Does this imply that the entity weather.darksky_weather (or weather.dark_sky for that matter) are not defined? If so is there a way i can see what states might be defined?
weather:
- platform: darksky
api_key: !secret darksky_apikey
update_interval: '00:10:00'
name: Weather `<-- This name must match`
monitored_conditions:
- summary
- icon
...
views:
- title: Weather
icon: mdi:cloud-question
cards:
- type: weather-forecast
entity: weather.weather `<-- This part after the dot and also be lower case`
