Hi Guys, im new to Node Red and hooked up my Smartmeter. Now i want to isolate this Value on the button. But how can i do it over the function node. Sorry i have non coding skills and this is my last problem to solve
You can move or copy the value to msg.payload using a change node.
Also, in case you are not aware, 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.
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.
