I wanted to give something back to the community as I absolutely love all the cool projects you share on here.
This is probably my most impressive card.
Here’s how I tell the phases of the moon. If it’s full, an eye grabbing image of a werewolf displays to let me know… be extra careful this evening taking out the bins.
Also, I wanted to make sure this didn’t exist in HA yet so I did a quick search for werewolf and werewolves. Nothing came back.
You’ll need the moon integration below in your config.yaml configuration file.
here’s the card code I use…

--------------------- ATTENTION: WEREWOLVES ARE OUT

show_name: true
show_state: false
this is normally what it looks like…
but if there’s werewolves out it looks like this…
keep your eyes open 
and stay safe.
