Semantic Model Location Card - Humidity badge averages non % numbers

[ghostface]

I have a Room with items for both relative (in %) and absolute humidity in (g/m³).

The location card generated from the semantic model shows an incorrect humidity value badge by showing the average value of relative humidity+absolute humidity.

Expected Behavior

Absolute humidity is a Number:Density Item with g/m³ as unit so adding it to the relative humidity percentage doesn't make a lot of sense. Just ignoring non percentage units is what I would expect.

Current Behavior

It shows the average of rel humidity % and absolute humidity (g/m³) in %

So the following:

• temperature of 21.6°C
• rel. Humidity of 58.48%
• abs. Humidity of 11.09 g/m³

Will show up as 35% humidity on the location card badge.

Possible Solution

Ignore units which can't be converted to % ?

Steps to Reproduce (for Bugs)

semantic model

        Group   gSemanticRoom      "Room"            <niveau>                    ["Room"]
            Group gSemanticSensorEquipment         "Sensor"  <heating>          (gSemanticRoom)             ["Sensor"]

things

  Type number        : sensorHumidty           "rel. Humidity    [ ga="9.007:<5/0/1" ]
  Type number        : sensorTemperature           "Temperatur"    [ ga="9.001:<5/0/0" ]

items

  Number:Dimensionless  sensor_relHumidity   "rel. Humidity  [%.1f %]"                <humidity>       (gSemanticSensorEquipment,G_Humidity)      ["Measurement","Humidity"]      { channel="knx:device:bridge:generic:sensorHumidity", unit="%" , stateDescription=""[ pattern="%.2f %unit%" ] }

rule

import org.openhab.core.model.script.ScriptServiceUtil 

rule "humidityMonitoringAbsoluteConversion"
when
    Member of G_Humidity changed or
    Member of G_Temperature changed
then
    val ir = ScriptServiceUtil.getItemRegistry
    var base_name = triggeringItem.name.split("_").get(0)
    try {
        var rel_humidity = ir.getItem(base_name + "_relHumidity").state as QuantityType// as DecimalType
        var temperature = ir.getItem(base_name + "_Temperature").state as QuantityType// as DecimalType
        var Number c1 = ((17.67*temperature.floatValue)/(temperature.floatValue+243.5))
        val abs_humidity = (Math::pow(Math::E,c1.doubleValue)*6.112*2.1674*rel_humidity.floatValue) /(273.15+temperature.floatValue)
        var abs_humidity_item = ir.getItem(base_name + "_absHumidity")// as DecimalType
        abs_humidity_item.postUpdate(abs_humidity)
    } catch(org.openhab.core.items.ItemLookupException e) {
        //oops not found
    }
end

Context

I do calculate the absolute humidity via a rule from the temperature and relative humidity. But I don't think that's totally relevant.
