The Netatmo CO² shows in the widget correct 1020 ppm, but in the chart it is 0,001.
Is there a way to show the values also the same as the widget instead of 0,001 or 0,002 and so on?
I see this as a minor deficiency in the UI charting.
Desirable behaviour -
If an Item has a default unit given in Item’s pattern metadata, use it for charting.
But it may not.
If an Item has an actual unit given in Item’s state - that is after all, a requirement for a Quantity type - use that for charting.
I suspect the reality is more about use of historical data from persistence, which relies on metadata to reconstruct units.
