Home Assistant + NodeRED logic when several devices have different values

Unless you provide a debug output of the nodes, nor can anyone else.

BTW, what you are asing is very very base knowledge. I'll post some info and links below to help you to help yourself

1 this will bring you on leaps and bounds

I recommend watching this playlist: Node-RED Essentials. 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.

2 getting data and property paths

There’s a great page in the docs (Working with messages : Node-RED) 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.
