When using node-red with raspberry pi 3 GPIO, node-red will send a message, every time the state changes (= rising and falling trigger). Is it possible to only send messages on rising trigger?
Using a script afterwards is not the solution.
The short answer is: no.
Workaround: feed output from your GPIO input node into a switch node with only 1 rule:
msg.payload > previous value
