Search a Node for route the payload

General
1

Hi,

i'm searching for a node to route the payload switched from an externel signal.
for example:
send a payload "1" to the "route node" an all incoming payloads routed to OUT "1" / send a payload "2" to the "route node" an all incoming payloads routed to OUT "2"

so like a switch node with an external control input

thankx in advance

Hi @Flixm

You can achieve this with the core nodes, using a context value as the property the Switch node checks against.

  1. Configure the Switch node to check the value of flow.myRoute - add as many outputs as you need.
  2. Use a Change node to set the value of flow.myRoute to whatever value you want the Switch node to route for.

Okay maybe i need need to explain it more detailed.

I have a payload which does not change but i want to route it to another target node.

So actually i use two gate nodes which working opposite to route the Payloads to another target.

hope that's better to understand

@knolleary's suggestion should do what you want. Alternatively look at node-red-contrib-msg-router (node) - Node-RED which has not been updated for several years, but is maintained by a regular contributer here (@BartButenaers) so I am sure it is well supported.

Okay, i'll try it. I never worked with flows ... So I need a bit more experience.

I'll check your suggestions.

Thx

That's what i need!

i was a bit confused about the two not wired Nodes. After i connected them to the Main Switch it works like i need it.

Thanks for the quick answers.
