Editing a switch node base value from the dashboard

[zsoni96]

Hello everyone,

I have a question : Can you somehow edit the base value of a switch node in dashboard?

In my case the switch node sends a payload when the value is bigger than 3000 but can i somehow edit that value from the dashboard instead of opening it from the node itself?? eg.: instead of 3000 to be 200?

Instead of a fixed value in the switch node use a global variable.

Also if the value to be compared against is in the message then you can compare against msg.some_attribute

Can you please send me an example flow? I have no idea how to do it.
I would really appreciate it

I have no idea how to do it.

Have a careful read of the node red docs page Working with Messages, then tell us what in particular you don't know how to do, if you still don't.

So i set up a switch to compare it to msg.topic (base value of it comes from an inject and the value is 10)
And then i pass a number there as an msg.payload which is bigger and one which is smaller than 10 but nothing happens

Same happens if i use a global varaible

[{"id":"79ee503e.0c074","type":"function","z":"2cf862d7.502fee","name":"","func":"var a= global.get(\"temp\");\nmsg.payload= a;\nreturn msg;","outputs":1,"noerr":0,"x":790,"y":540,"wires":[[]]}]

Try this (note, as well as trying to use values from multiple messages at once you had misspelt payload in the switch node
