the question was, how do you KNOW that music is playing? what code tells u?

I would expect the spotify playing module to do a sendNotification(“spotify_Playing”,something);

so that other modules might know… it does not do that (looking at the code)…

you could fork the existing code and add the 2 lines (one playing, one not) of code and submit an enhancement (pull) request to the module owner…

Wow!! Thank you very much for that two tricks! Working just perfectly. I think this monitor is now the perfect one for my mirror. Although this will take some time… :)
