Number smaler then -100

[arohleder (Achim Rohleder)]

Hello,
does somebody knows a way to check if a number is bigger or smaler then -100 in a rule?
Thank you for Help!!!

Err… If you are talking about DSL Rules:

if(myNumber < -100)
    do a
else 
    do b

Thats easy. Thanks!!

Or use blockly

which shows you how to do that in ECMAScript:

var myNum;

myNum = -101;
if (myNum < -100) {
  console.log('do this if value is less than -100');
} else {
  concole.log('do that');
}

Thank you for replay. Many roads lead to Rome.
I have solved it now:

rule “Zuviel_Strom”

when
Item Zaeler_Momentan changed
then

if (Zaeler_Momentan.state < 0 && Zuviel_Strom_Schalter.state == ON)
{}
else
{
if (Zaeler_Momentan.state < -100)
{ Zuviel_Strom_Schalter.sendCommand(ON)
}

else
{ Zuviel_Strom_Schalter.sendCommand(OFF)
}
}
end

more straight forward:

rule “zu viel Strom”
when
    Item Zaeler_Momentan changed
then
    if(!(Zaeler_Momentan.state < 0 && Zuviel_Strom_Schalter.state == ON)) 
        if(Zaeler_Momentan.state < -100) {
            Zuviel_Strom_Schalter.sendCommand(ON)
        } else {
            Zuviel_Strom_Schalter.sendCommand(OFF)
        }
    }
end

Is Zuviel_Strom_Schalter a real hardware? if not (i.e. it’s a proxy item or an unbound item), better use .postUpdate() instead of .sendCommand()
