Here is the result with the following items and sitemap:

Number:Temperature CurrentTemp "Current Temp [%.1f °C]" <temperature> (GTest) [ "Measurement", "Temperature" ]
Number:Temperature SetpointTemp "Setpoint Temp [%.1f °C]" <temperature> (GTest) [ "Setpoint", "Temperature" ]
Number CurrentPressure "Pressure [%.0f hPa]" <"oh:classic:pressure">
String TestString "Test string [%s]"

sitemap test label="Tests"
{
        Frame {
                Default item=CurrentTemp icon="temperature" iconcolor=["pink"]
                Default item=CurrentPressure icon="if:wi:day-light-wind" iconcolor=[<=1010="red","orange"]
                Default item=SetpointTemp icon="iconify:wi:day-sunny-overcast" iconcolor=[<=15="blue","green"]
                Selection item=TestString icon="material:favorite" iconcolor=[=="test"="pink","yellow"]
        }
}
