Ability to add sensor for grid consumption

[ianpiface]

Hi,

I'm trying to use the Energy dashboard to plot the near realtime grid consumption. I can see that there is a diagnostic sensor for it but unfortunately it's not listed in the sensors dropdown when trying to add to the Energy dashboard.

There is a sensor showing for the ever increasing daily consumption but thats not what I'd like to view.

Is there a way it could be added please?

Thanks
