[SOLVED] Rule startup issue - The method toDateMidnight() from the type DateTime is deprecated

I have a rule that brings up an error message when system is started. any idea what goes wrong…seems to work but would love to have as little errors in my log files as possible. Thanks to the experts for a quick check.

rule "Update TempOutside Min&Max"
when
Item MyTemp_Outside received update
then
    var Number Xtemp
    if (MyTemp_Outside.state instanceof DecimalType) {
            Xtemp = (MyTemp_Outside.minimumSince(now.toDateMidnight, "rrd4j").state as DecimalType)
            Xtemp = (Math::round(Xtemp.floatValue*10.0)/10.0)
            postUpdate(MyTempOutMIN, Xtemp)

            Xtemp = MyTemp_Outside.maximumSince(now.toDateMidnight, "rrd4j").state as DecimalType
            Xtemp = (Math::round(Xtemp.floatValue*10.0)/10.0)
            postUpdate(MyTempOutMAX, Xtemp)
    }
end

Simple rule to get average temp. return postUpdate(org.eclipse.smarthome.core.items.Item,java.lang.Number) on instance: null

Hope that is a typo in the posting. It should be everyMinute. toDateMidnight is deprecated. You should use now.withTimeAtStartOfDay. But that isn’t an error. But there is an error. maximumSince and minimumSince return a HistoricItem, meaning you get an actual Item object, not just a State. So you need to call .state: var Number tempA = UnitaEsternaTemperatura.maximumSince(now.toDateMidnight).state var Number tempB = UnitaEsternaTemperatura.minimumSince(now.toDateMidnight).st…

thanks a lot…

That fixed it -> You should use now.withTimeAtStartOfDay
