Anyone using KDE ?

I want to put my "energy consumption" in watts as a widget or a taskbar icon or something.

I tried to put it in system monitor new page but there isn't any sensor named as such. But energy monitor does say 6 or 10 watts depending on load so the data is being given from somewhere

I checked power>battery but that too did not have any such option.

I believe it shows up if you hover over the battery icon in the panel.

Seems I was mistaken, but it looks like you can still derive the power by looking in /sys/class/power_supply/BAT0/ and whether ../AC/online is 0.

I have the Power Monitor widget and it does derive from BAT0, according to the source code for the widget.

On my laptop BAT0 a bit slow to update, with an update rate of about 0.2Hz.

I've also noted my desktop's UPS reports different power draw values on its status display and the UPS' USB interface, by about 10% or so.
