Expected Behavior

rule "Teufel_Amp_ON"
when Item harmony_activity changed
then logInfo("TEST", "prev" + Media_Aktion.previousState(true, "rrd4j").state)
}
end

I want to get the last not similar to the actual state out of the rrd4j database

Current Behavior

Yours is probably answered in this thread.

Hey Chris,

I came from the Community Forum, where Rich Koshak suggested to file an issue on GitHub in this case, see Topic:
https://community.openhab.org/t/rrd4j-only-stores-one-datapoint/84639/18
Your recomended post did not solve my Problem with rrd4j.
I am now using mapdb which works, but I think this is an issue with rrd4j which Maybe should be solved.
