Hi, Remy,
wow, what a great work. the installation routine worked perfect... and just found the solution for the wrong time problem.
unfortunatly there is no indication for title and so on if i stream from spotify to moode directl.
Any hint?

Hi Matthias. As for now you can't display the data when using spotify or airplay. Volumio can display those data without a problem. Have a look at this thread

Hi, Remy,
but moode sounds better and has no trouble while spotify is streaming. Volumio has... thats why i changed to moode!!
so... its not a problem...

Yes, I also think moOde is much better than volumio, especially the interface. And since i don't use spotify and only rarely use airplay, it is not a problem for me.

Hello. I've finally just updated my player from the beta version (lol) and installed this awesome LCD script. I am using a parallel interface with a 20x4 LCD. The only thing is, I used to have a backlight control and I don't see this implemented anywhere in your script. Is there any way to do this? For me it was, backlight on when playing or paused, and off when stopped..
I guess this might be a bit more complicated with the Weather and other options you have.
Here is the code I was using before:
