Node-Red EM24 Gridmeter: "Power" missing

Hi Community!

After an update of Venus from 2.94 to 3.13. I cannot find "Power" anylonger in the list of measurements for my gridmeter.

Due to the update I have to reselect/migrate all devices, like the Gridmeter

Before reselecting/migrating:

After:

There are the power values for L1 o L3 but not the total.

Any idea what I can do?

You can definitely use the custom input node to retrieve the value, but I'll check where that went. I may have mistakenly removed that path on one of the updates. If that is the case, I'll add it again.

Thanks @Dirk-Jan Faber (Victron Energy)

I customized a node like

[
    {
        "id": "18ab871be15c79f3",
        "type": "victron-input-gridmeter",
        "z": "92033abe5dd40cdd",
        "service": "com.victronenergy.grid/40",
        "path": "/Ac/Power",
        "serviceObj": {
            "service": "com.victronenergy.grid/40",
            "name": "GridMeter"
        },
        "pathObj": {
            "path": "/Ac/Power",
            "type": "float",
            "name": "Power (W)"
        },
        "name": "",
        "onlyChanges": false,
        "x": 690,
        "y": 200,
        "wires": [
            []
        ]
    }
]

and this works

I hope I did it corretly.

That works, but I meant using the custom input node. And then selecting the grid meter + path.

I got it (now), thanks!

Was not aware about this type of node.

Hi @Dirk-Jan Faber (Victron Energy) ,

I updated today to newest FW-version (v3.14) but Power (W) still not available for GridMeter.
Any news on this? Thanks!

It has been added to the node-red-contrib-victron node from version 1.5.5, but as 3.14 does not carry the latest node-red-contrib-victron, running the latest stable release won't show it.

The options are to either switch to the latest candidate firmware release (the current one running version 1.5.9) or wait a bit longer until 3.20 is released.
