Group Address value in SVG icon

[Thomas]

Working solution:

Code:

$(function(){
  $('.rotate').each(function(i, el) {
        var $el = $(el), addr = $el.data('object'); // or 'status-object'
      grp.listen(addr, function(obj) {
        $el.children(".icon").css('transform', 'rotate(' + (180-(obj.value*0.9)) + 'deg)');
    });
     });
});
