Thanks Gene, now is iltle bit clear.
If I use Sensor.Temperature the widget work fine, widget display correct value, icon and unit of mesure.
but in my case the with the ADC I tray to mesure voltage, current , etc.
if I use Sensor.Tensione still not work.
I found one istruction like case 'Sensor.Temperature': in the widget's javascript but there isn't
I'm confused where is te contol? can I use one generic name for parameters with name starting with "Sensor."?
thank you a lot
