[SOLVED] How to split a string in a rule

Hi. I’m new to openhab. I have configured an MQTT feed from my emonpi to openhab and got it working OK. What my item is returned, is a string of values like “2307,28,0,2253,241.22,300,300,300,300,300,300,1”. I want to be able to pick out one of the values and display just that value (eg. 2253). I was trying to do that in a rule with a string array and toString.split(",") - that seems to work OK but when I reference one of the array variables (array[0]) it says it is NULL. Can anyone tell me …

I had a look at that. But I dont know how to use MQTT. I’m new to openhab.

Is there another way?

You don’t have to use MQTT, pay attention to JS transform mentioned there.
Another example (mine) is here.
