I read your topic 2 times. Does this means output will be generated only when all the inputs received. Means I will add button and send string pass from button then only joint node will pass value. Is my understanding correct?

Feed the set data message and the button into the Join node. Make sure they have different topics.
Set the Join node to 2 message parts and After Every Subsequent Message.
Look at the debug messages you get out.
Then add a Switch node set to only pass messages with the button topic.
If you need to post a flow here then just export the important nodes, we don't need to see all the stuff before the set data node, and paste it here using the `` button at the top of the forum text input window when pasting it in.

I don't understand. You can set the topic in a function node.
Is the right value coming out of the setdata node?
Are you getting the right data out of the set data node? If so feed it into a debug node and show me.

Use a Change node to Move the property you want to the payload.

Best to start a new thread if you have a new question.
