Hello everyone. i'm new to node red. Whenever I get a string via udp it overwrites my table row.
How can I create a new row every time I get new data?
Welcome to the forum @simonecrevatin
It is important to remember when you ask a question that we know absolutely nothing about your system.
So the first question is what table? A table in a database? A table in the dashboard?
If it is on the dashboard then add a debug node to see what you are sending to the table.
[Edit] Sorry, I have just noticed that you have asked this on the dashboard category so that answers the first question. Have a look and see what you are sending to the table.
hi colin and thanks for replying. what comes to the table is right. the problem is that every time the data arrives it does not add a line below but always overwrites the same one.

can you make a small example flow (without any 'contrib' nodes) demonstraiting the issue?
that will make it much easier for someone else to help ou out.
Thanks everyone I solved.
Great! Could you provide your solution for anyone else that might have the same problem in the future?
