Units of Measurement (UoM) missing: g/m² and Wh/m² (for solar panels monitoring) #4143

Open lavirott opened 5 months ago

lavirott commented 5 months ago

Hi openHAB developers,

This feature request is related to a OH Community discussion.

I have a sensor returning values in g/m² (for a snow load on photovoltaic panels). The unit is therefore a unit of surface mass, which should be in ArealDensity. Unfortunately, there’s only the DU unit (which I don’t know how to convert into g/m²).

This sensor also provides information in W/m² (Quantity: Intensity, Unit Irradiance), so no problem for this one, but also energy in Wh/m². I can’t find this type of unit either.

So, is it possible to add these units in OH 4 ?

@lavirott the astro binding does provide data with dimension Intensity (W/m²) so i think rhis should be allready be there.

I know that W/m² is existing, but I'm looking for Wh/m² (not power but energy by m²)
