It seems like the picture cards can't use an image entity in the 'state_image' section of the configuration, the cards only use URLs.
Frigate provides snapshots of my dog as image entities (image.livingroom_camera_dog, image.office_camera_dog) and I'd like to use them in a picture card using 'state_image' to select which image to show based on the frigate sensor that tracks which camera last saw my dog. It seems like image entities are not valid for that configuration. Is there a way to use the image entity directly without taking a snapshot of it or finding a way to store the snapshot locally? Can I use an image stored in the MQTT server? Is there a card for showing image entities?
Thanks.
