Change attribute in visu following a knx object

[Erwin van der Zwart]

Your example works fine for me. Use browser dev tools (F12) to check if the element has a specific class.

I think he did not also add the class el-disabled to the additonal classes so the CSS does not apply to the element because of the class dis_da_totale is used, so intthis case the additional class needs to hold both dis_da_totale el-disabled or am i wrong?
