Wrong wind speed value in meteoblue add-on (unit confusion)

Add-ons Bindings
1

It seems that I get wrong wind speed values in the meteoblue add-on. Meteoblue is delivering them in m/s but the add-on is interpreting the value as km/h. Consequently the value is much to low and should be the actual value times 3.6. If I query the API directly (see below), the unit information is in there - is it just not considered in the addon, which is assuming km/h?

"units": 
{
	"time": "YYYY-MM-DD hh:mm", 
	"predictability": "percent", 
	"precipitation_probability": "percent", 
	"pressure": "hPa", 
	"relativehumidity": "percent", 
	"co": "ug/m3", 
	"temperature": "C", 
	"winddirection": "degree", 
	"precipitation": "mm", 
	"windspeed": "ms-1"
}

The documentation says the default units depend on your locale.

No that is not the point. E.g.

Number:Speed        WeatherInformationForecastTomorrowMaxWindSpeed               "Maximum wind speed [%.0f %unit%]"               {channel="meteoblue:weather:62281c1e:forecastTomorrow#maxWindSpeed"}

is delivering a value of 7.7 km/h, however it should be 7.7 m/s or 27.72 km/h

See as well what I get from the meteoblue API:

Yes, that’s a defect you should log.

As a workaround, you can probably get the output to show 7.7 m/s with this change:

"Maximum wind speed [%.0f] m/s"
