Mutiple paths in single payload

[stu1811]

I'm trying to trigger on a event from my Inovelli LZW30-SN (light switch). I only want to do something when payload.event.label == "Scene 003" and payload.event.value == "KeyPressed". What is the best way to do multiple conditions on the same payload with different paths? If possible I'd like to use a flow since I'm just starting my node red adventure.

Edit: I figured out how to use the function block and check for both paths then edit the msg payload. It's very clunky. I assume there is a better way..

Edit 2: I'm using now red in home assistant. Not sure if that matters.

if (msg.payload.event.label == "Scene 003" &&
msg.payload.event.value == "KeyPressed")
{
var yay_msg = msg;
yay_msg.payload.event_type = "yay";
return yay_msg;
}
else
{
var del_msg = msg;
del_msg.payload.event_type="none"
return del_msg;
}

Gday stu.. welcome to the forum

Pretty sure, if I read this right you could of achieved the same with a switch node with 2 outputs

You could consider creating an actual flow that builds the logic, easier to debug;

2 examples (flow and function node):

Thanks for the flow. I was able to modify your flow to work. The relabeling at the end really helped.
