Solved NODE-RED Join push variable

Hi there!

I would like to ask, how to integrate a variable into a join push message, so that the join push node only sends a variable?

Using the % in the node's 'message" doesn't seem to work.

Thank you!

 

Sorrily, it does not help

If I make a function node, populating it with the following

msg.text = '%AirCondOn';
msg.devices = "Galaxy Note9";
return msg;

Where %AirCondOn is a global variable within nodered, it just sends %AirCondOn, not the value.

 

Tried that too, nodered gives me this error:

"ReferenceError: AirCondOn is not defined (line 1, col 12)"

 

Yes I overlooked something, and just found out thats not how I access that variable...

I use a function node:

var ObtainedData = global.get("AirCondOn")
msg.payload = ObtainedData;
return msg;

and then another function node

msg.text = msg.payload;
msg.devices = "Galaxy Note9";
return msg;

this way, it works.

Thanks anyways

 

I can't believe what's happening. Literally

I made this mentioned flow as a test flow, with a simple inject at the start.

var ObtainedData = global.get("AirCondOn")
msg.payload = ObtainedData;
return msg;

and then another function node

msg.text = msg.payload;
msg.devices = "Galaxy Note9";
return msg;

It worked by itself.

When I copied it into the desired place, it now gives me another error:
msg : string[20]
"text needs to be set"

What the hekk is going on?

 

Yea tried that too, gives the same error, and doesn't send anything.

What I don't get is how is it even possible, that it worked (I didn't only looked at the flow, I checked my phone, where the flow sent the variable, and it did send the variable value), I copied, and suddenly it doesn't work.

Tried rewriting the every node, tried restarting node-red itself, no success...
Maybe tomorroww by itself, it will work again.

 

Works again, using () - which I don't even understand...

msg.devices = "Galaxy Note9";
msg.text = (msg.payload);
return msg;
