Sending a state to an item, after splitting the state item

I would like to NOT use val or vars.

That just makes it difficult for you to manage and debug. They do not cost you anything.

@DivineJimmi

Okay, that is a string

@DivineJimmi

triggeringItemName.split('_').get(1)).sendCommand(

Strings do not have a .sendCommand() method.

There is a sendCommand("someItem", "someCommand") Action, you would need to give that two strings as arguments.

@DivineJimmi

("TemperatureWhenWindowOpen_" + triggeringItemName.split('_').get(1))

That’s a string as well.

@DivineJimmi

("TemperatureWhenWindowOpen_" + triggeringItemName.split('_').get(1)).state

Strings do not have a .state method.

Not so easy to work around this time, you need the technique to get hold of an Item object from its itemname string

[Rules DSL] Get item from string name!

For a couple years now, I’ve been wanting/looking for a way to construct an item from its name as a string. There are other ways to do this, and the most popular requires the item to be in a group, which can have it’s challenges. I’ll keep this short and SWEET… I finally figured it out, and it is extremely simple! For OH 2.x, you’ll need this import… import org.eclipse.smarthome.model.script.ScriptServiceUtil For OH 3.x, this import instead… import org.openhab.core.model.script.ScriptService…
