Missing Unit of Measurement

There is a missing UoM: Calory. As some brands of scales deliver this sort of data, it would be nice to implement this unit.

Open a Github issue. But calories are Joule so not missing.
Wanna home automate your nutrition ?

1 cal = 4.184 J
As I have a scale which does the measurement, I want to see it in openHAB :slight_smile:
