 To use the display on LMS, add repository https://raw.githubusercontent.com/sle118/squeezelite-esp32/master/plugin/repo.xml. You will then be able to tweak how the vu-meter and spectrum analyzer are displayed, as well as size of artwork. You can also install the excellent plugin "Music Information Screen" which is super useful to tweak the layout.
