Feature request: listen to other things than payload

[dirkjanfaber]

Thanks for the nice node.

What I am currently missing and would like to have is that the input object is configurable. So that the node can listen to msg.blink instead of msg.payload. This would save me a change node in my flow.

It's no big deal. I have implemented this for myself and put it into operation.
Unfortunately, I can only use javascript, not TS.
You can find an example at https://github.com/das399igste/node-red-contrib-ui-led or via Forks
