Hi, i have the following problem: I want to compare a value/variable inside a rule to many numbers. If the value is the same like one of the numbers, then the rule should do something. Is this possible with only a variable - without a number-item? With items i know the command “if xxx = member of …

Well, you’ve used findFirst to get hold of two Items (if the search worked) and you’ve chosen to call those Items authorized and unauthorized.

[image] halloween: I have a rfid-reader and many rfid-chips. Now i want to do something inside a rule, when a known rfid-chip is recognized. How would you solve this? Should i put all known rfid-numbers into number-items? I actually wrote a DP for this exact use case. See Approach 3 in Desig…

Thanks! Works great in my first test.

@rlkoshak Another small question to your DP: I know this: item.state shows the state of the item item.name shows the name of the item How can i get the description of the item? String item-name "description of the item" I want to make an output of the description in a logInfo inside my rule.

item.label I think that’s one of those undocumented-but-works features

Here is the part of my rule: What is the right syntax for using item.label in my variable-declaration? I get the number of my rfid-chip. My rfid-chips are stored as items like this String RFID_12345 "rfid chip yellow" And this is inside my rule: val itemName = "RFID_"+receivedCommand val item…

Your Item is named RFID_12345. So you’d access it’s label as RFID_12345.label What your trying to do is indirection. You can’t just have a string “rhubarb” and attempt say “rhubarb”.state, expecting it to act like an Item. There’s a least two ways to get hold of an actual Item object if you ha…

I already do this like rlkoshaks design pattern method #3 This works great, here is my whole rule: rule "RFID Haustuer triggered" when Item RFID_uid_haustuer received command then val itemName = "RFID_"+receivedCommand //val itemLabel = itemName.label // Thi…

Thanks! With authorized.label it works. I didn´t try this, because my test with itemName.label failed…
