InfluxdB Out Node in Node Red

1

Does anybody know how to pass a payload, topic or flow variable into the InfluxdB Out node, as the measurement name/field?

Usually {{payload}} or {{msg.topic}} works in order to insert the payload/topic into another node. But clearly that doesn’t work for an ‘influx out node’ in node-red.

Hi @edaustin

Here is what my InfluxDB Out node settings look like:

and here is the function node that formats the data just before this node, where I am feeding two fields & field values (temperature and millivolts), each with the tag “Meastype” and tag value “actual”. In another flow, I am grabbing the setpoint value and defining that as the tag value, so that in InfluxDB I can compare actual vs setpoint.

msg.payload = [
    [{
        temperature: msg.payload.temperature
    },
    {
        MeasType: "actual"
    }],
    [{
        millivolts: msg.payload.millivolts
    },
    {
        MeasType: "actual"
    }]
];
return msg;
