Create a single page with 3 Lines of Voltage L1,L2,L3 between 0 and 300 V

Dashboard
1

Hi to everyone,

I have got a flow for the SMA Sunny Home Manager 2 which gives me all the data into the designed layout boxes on the dashboard on 2 pages as groups.

I added another group which should finally show a continuesly courve for the 3 phase in Voltage per second.
First step:
I tried it via the graph-node for creating this courve, but it shows the name of the phase with the value in V. for eg. Phase 1 240,56 V in the designed layout box. No courve shows up for that single phase.
How can I create this phase courve?
Which nodes do I have to use? function-node?

Seconed step:
The page should show all the voltages of the three phase on one sheet.

Reason:
There are big variations (more than the +-15% limit allowed) of the voltage in my grid from iberdrola. The sheet will be needed to record and show them the problem to get any solution.

Thanks in advance
John

Perhaps you can show us a picture of this?

An export of your flow and a sample of the data would help too. Please don't post these as pictures or we won't be able to work with them.

In order to make code readable and usable it is necessary to surround your code with three backticks (also known as a left quote or backquote ```)

```

```

See this post for more details - How to share code or flow json

There’s a great page in the docs (Working with messages : Node-RED) that will explain how to use the debug panel to copy 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.
