Hi all,

I have a node-red flow running on a touch screen. And I want to run the flow when a finger is touched on anywhere on touch screen, can't find any node doing this. Would someone help?

What OS is running the touch screen and what software are you running that can pick up touch events? Are you running a browser for example or do you have full control of the touch device?
