Maybe I’ll give it a try. Although I can see a lot of mysql queries to get the last updated item. Might not be a big problem, but I only have 16 rollershutters and I guess they will never change. So I’ll see which way to go.
Currently I have still the problem that the rule gets triggered twice, same like in this post from me Rule triggered twice with knx binding
I still have to play around to get what I want…
