Thanks for link. I went for this https://forum.logicmachine.net/showthrea...08#pid2108
Script as it checks setp and temp in room with class fu ction. I get this to workon text and change text color.
In case I add an icon it doesnt work. Is it possible to change a white picture or a blank picture(to make a room box?)
