I’m uncertain what to put where.
been playing with this lately.
you have under appearance selected the text only display so you will not get any benefit from listing senors where you have them shown.
but if you were to select say pie-chart or bar-chart under appearance, then the sensors you have shown will be represented by a graph.
if you were to then take those sensors and move them down into the text-only box you get the same results you do now (no graphing).
not sure what the total box does if you put all three sensors in there.
