Javascript, use value of the main knx object and display a icon

[equalizer]

Another approach is to use image element, attach object listeners in Custom JS and change img src depending on the value.

Is that using a .lp file and creating a canvas to display the icon?  I started digging into that aproach and it started to get a little complex even with the image url paths hard coded :-)  I may have another look at that though as I didnt know about the object listener aproch I was also trying to make a custom basic client server via url parmiters data link happen...
