Hi everyone, I have recently started programming with node red.

I should filter in this list of values, only the given temperature of the new state. excluding all the others.

There’s a great page in the docs that will explain how to use the debug panel to find the right path to any data item.

Pay particular attention to the part about the buttons that appear under your mouse pointer when you over hover a debug message property in the sidebar.

Once you have the path you can either use it or move it to payload using a change node.

Ps, this is a basic fundamental of node-red so forgive me for saying you might need to do some training?

I recommend watching this playlist: [Node-RED Essentials](https://www.youtube.com/playlist?list=PLyNBB9VCLmo1hyO-4fIZ08gqFcXBkHy-6). The videos are done by the developers of node-red. They're nice & short and to the point. You will understand a whole lot more in about 1 hour. A small investment for a lot of gain.
