Detect Item state type

So the rule needs to know if the state received is a Number in order to map it to the respective string with a transform.

Why go through this extra step? Why but just set the Item with the Stein in the first place?

As far as I understand I can not create functions inside the rules.

There is. They are called lambdas. But if you stay to head down that path you usually end up with long brittle code that doesn’t work that well.

Major Edit: Rewrote with the cleaner OH 2.3 syntax. The example lambda on the OH 1 wiki is overly complex and as written will not work in OH 2. This quick example will show a super simple lambda example with copious notes. Here is the code without comments. It takes in an Item, logs it’s state and returns a slightly modified version of the String logged. val log= [ GenericItem s | logInfo("lambda", s.state.toString) s.state.toString + " logged" ] rule "Call Lambda" when // some t…

What you are trying to do is actually written up as a design pattern. Design Pattern: Separation of Behaviors

An alternative approach to what @vzorglub recommends (note the typo, it’s missing the second.= In the if statement) is

if(receivedCommand instance of DecimalType) //do number stuff
