Hi, I’m quite new to Openhab and I can’t get my first rules to trigger. Maybe someone can help me.
The first rule should set the Gang_Soll item to 20 by startup but when i reboot the System this Item does not have any Value. The Second Rule should trigger when one of the items change in value via a setpoint in the Sitemap but even if I remove the if comparison it does noch set the HeizungGang Item to ON
Cool you are nearly there.
System started
then
Thread::sleep(30000)
if blah foo bar
Next Rule you don’t need the or after Gand_Soll
Items always have some state, but you might need to find out what exactly.
if (Gang_Soll.state == Uninitialized) ...
You’re following a very old tutorial, I suspect.
In openHAB-1, newly born Items at system startup time have a state of Uninitialized.
In openHAB-2, they have state NULL
You can use logInfo() and a little thought to help diagnose issues like this, and see the output in your openhab.log
if (Gang_Soll.state == Uninitialized) {
// do stuff
} else {
logInfo("test", "Unexpected state " + Gang_Soll.state.toString)
}
Thank you! Now it works 
I had several Problems. It worked when changing the Gang_Soll.state == NULL. Also I was trying to convert a temperature Value to a Double via as DecimalType , it worked when using as QuantityType.
