maybe try with with node's debounce time set to 0 ?
I have already tried with the node's debounce time set to 0. It doesn't catch my short pulses.
OK - You could try the gpiod nodes instead https://www.npmjs.com/package/node-red-node-pi-gpiod - they use a native C service - which may cope better. (But I've not tested it in your situation)
Thanks for pointing out this node! It helped me eliminate a pythonshell node and corresponding script it called in a garage door controller I'm working on.
