This my second day learning node-red and I have no coding experience other than Basic (25 years ago). Here is the question: Is there a better way to change default payload output of Big Timer than adding 2 “change” nodes in parallel? [image]

Well spotted - it does indeed say that ... though it doesn't actually specify string or number - the implication is that it's a number. I have just tested and it does work with both strings and numbers (and booleans as well) ... so yes I'll clarify the docs. You may want to retry in your flow - or…

A solution using only one change node: [not]

Thanks, Definetly better than 2 nodes. Is there a tutorial on preinstalled nodes covering all possible options?

Controlling gpio pins on rpi to activate relays. Since initial state of gpio pin is high(1) I couldn’t use default output2 ( 1 for on, 0 for off) of big timer to control it

I don't know, but have you checked whether GPIO Out works with strings "0" and "1"?

Not 100% sure but I think it’s only 0,1 I could have a change node in front of each pin and have different types of payloads to work with, but at this moment I don’t see any reasons why would I want to use something besides 0 and 1. It is a relay and it’s ether on or off. Also, ones I’m done with …
