filter or routing variables to UI

[PCu1]

Hello,

I think it is a basic question but I can't find a solution.

I read 4 variables, 2 fan RPM and 2 temperatures.

I route the two RPM to a gauge, and I would like the temperature to a char (only the temperature). Because the scale is very different.

Gauge is working, I can filter.

I don't know what to insert between "processing" and "chart" to remove the RPM variables to the chart:

Thank you,

Pierre

Hello Pierre

There are 2 options :

• Create 2 groups of variables, one for the gauge and one for the chart. You will have 2 processing nodes, and one can be connected to the gauge, the other to the chart.
• Add some filtering nodes on the output of myVariables processing node. The "switch" node in the palette will do the job, filter on the property msg.payload.variablename and set == myVariable

The switch node configuration : (Copy this code, go to menu "import" and paste the code. then replace "myVariable" by your variable name)

[
    {
        "id": "2ca79e6f.a68e72",
        "type": "switch",
        "z": "8bf74b4c.0fa5f8",
        "name": "filter variable",
        "property": "payload.variablename",
        "propertyType": "msg",
        "rules": [
            {
                "t": "eq",
                "v": "myVariable",
                "vt": "str"
            }
        ],
        "checkall": "true",
        "repair": false,
        "outputs": 1,
        "x": 630,
        "y": 220,
        "wires": [
            [
                "b9d7ae86.0da72"
            ]
        ]
    }
]

Hi Stéphane,

Thank you for the answer.

For the first solution I had tried before but without success. I will try again.

For the second solution It works. But it seems that I need to add a filter for each variable. A single filter with multiple variables does not work.
