Knob widget decimal precision issue

Hello all,

I am trying to use a knob widget to show a progression / readout of energy used during the day.

My problem is that the knob widget does not use the number format in my item description and keeps all the decimals (all 8 of them) so the display of the widget is messed up because of the length of the value. Here is my item description:

Number	daily_heating_hotwater_kwh	"Cite Verte Energy [%.0f KWh]"		<hvac>	(gUtilities,gEnergy)

Any idea how I can make this more display-friendly ?

Set the step to 0.1 in the widget settings.
