The following rule completely halts the loading & execution of all the other rules. I read couple comments about double parsing but even after 20 minutes, this rule is still hanging the whole openhab. Any suggestions?
rule "Humidex Calculation"
when Item DewPoint changed
var temp = (GardenTemperature.state as Number).doubleValue
var dewPoint = (DewPoint.state as Number).doubleValue
var humidex = temp + 0.5555 * (6.11 * Math.exp((5417.753 * ((1/273.16) - (1/(273.15 + dewPoint))))) - 10)
logInfo("humidex", "Current Temp:" + temp + " Dew:" + dewPoint + " Humidex:" + humidex)
