with higher values it seems to work (BTW: I'm on 2.13 ...)
Right, the "old state" in setup I had removed - because for my understanding the setup will be called only once - after that the setter / getter.
And yes, this maybe bad for the "flapping" - but it does not help

Thanks for the hint about the delay value in loop!
