Trying to grok state_filters for picture-entity.
Wanting to be able to display some indication that a still image from a camera has not updated in over a minute.
The cameras are remote and sometimes the link goes down temporarily. So it would be great to be able to tell at a glance that the image is stale: Different colored 'name" text, or “Idle” changing to “Stale” or anything else.
Any ideas?
Thanks!
