HI,
@CCOSTAN
i can’t seem to find the error in my automation, could you please have a look?
i have edited https://github.com/CCOSTAN/Home-AssistantConfig/blob/a2485d167bdd0892617797fa8a0a87ce2a5eb9f2/automation/System/device_status.yaml
a bit and tailored it to my situation, apparently incorrectly …
the fact that the appletv_library is off is correct, which i hoped it would notify me of 
error:
