[SOLVED]How to calculate temperature real feel (feels like, heat index)

Setup, Configuration and Use Scripts & Rules
10

I use lambda, OH 3.3:

val heatIndex = [ Number TT, Number H |	
    val Number T = TT * 9/5 + 32
    var Number HI = 0.0

    if (T <= 40.0) {
        HI = T
    } else {
        HI = -42.379 + 2.04901523*T + 10.14333127*H - 0.22475541*T*H - 0.00683783*T*T - 0.05481717*H*H + 0.00122874*T*T*H + 0.00085282*T*H*H - 0.00000199*T*T*H*H

        if (H < 13 && T >= 80 && T <= 112) {
            HI = HI - ((13-H)/4)  * Math.sqrt(17-Math.abs(T.doubleValue-95)/17)
        } else if (H > 85 && T >= 80 && T <= 87) {
            HI = HI + ((H-85)/10) * ((87-T)/5)
        } else if (T < 80){
            HI = 0.5 * (T + 61.0 + ((T-68.0)*1.2) + (H*0.094))
        }
    }
    Math.round(((HI - 32) * 5/9).floatValue*10.0)/10.0
]

rule "SENS ROOM FeelsLike"
when
    Item roomSens_InWallTemp_R changed
then
        roomSens_FeelsLikeTemp.postUpdate(heatIndex.apply(roomSens_InWallTemp_R.state as Number, roomSens_InWallHum.state as Number)) 


end
