I have a chromecast that is powerfed from the tv, so when the TV turns off, it goes offline.
I don’t want the media-control to display when it’s offline as it just shows a red card.
I’ve tried using conditional and filter, but they both refer to states, and it doesn’t have a state when it’s offline.
So how do I do that?
Try the mini-media-card - it won’t give you a red screen
Is it this one GitHub - kalkih/mini-media-player: Minimalistic media card for Home Assistant Lovelace UI
?
The mini card looks quite nice. Though I can’t seem to get all the settings to work yet, and danish isn’t supported in the tts part 
ThankyoU!
Yes but the benefit is if the entity does not exist you don’t get that nice red box error.
