Hi, most problably a simple question, but I could not get the correct syntax yet. I have a entity “monat” which contains the current month as a string. I just want to evaluate in Node Red if the state is within a list of Months. Say month is in “Oktober, November,…”, see node below.
Any help? TX - JJ
