Hi there, I have a KNX water leakage sensor that sends nothing to the group address when there is no water detected. When there's a leakage it begins sending alternating zeroes and ones to the group address. In Node-RED I want to convert this to a simple flag that indicates if there's an alarm (1)…

[image] mathias-ewald: I might have configured the Trigger node wrong Sorry, I should have said to set 'Extend delay if new message arrives'. That stops it sending the false message until no input is received for 5 seconds.
