Hello Guys,
9 devices get at the same time the command to tell the IP adress, than they get another Command to tell the Devie name.
I get 9 answers, all with the own device topic, nice. But now i would like to join them in a single output.
The clue: The same toppic should merge. At the moment i get a joint output only on differant topics.
I was thinking thame topic and join the right massage to the right topic is easy... nope not for me 
Please give me a hint.
here is my flow:
