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](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.
