Is there a way how i can go sure that i don't get double entries in my CSV.  
I take data from a sensor every 30 sec, but if nothing changed, I want get a new entry in my CSV.  
Just if something changed (I get 5 different values).

Is this the same question that you have asked [here](https://discourse.nodered.org/t/node-red-csv-datatype/43081/6). If so then please don't do that. You just waste peoples time by doing that.
