This will be a no-brainer for 99% of people but I am lost at the moment. Simple task.

Via MQTT I get messages from a program (p4d). I receive them and have them converted to JSON. All messages have properties:

{"id":"UD:0x01","type":"UD","name":"Heizungsstatus","unit":"zst","state":"off","value":19,"action":"CHANGE"}

I want to store this in Influx with the measurement being "name" (Heizungsstatus) and the value being the value (19). I believe the msg.property I have to feed to influx out is

{"Heizungsstatus","19"}

How do I manipulate the msg properly? And of course I would need this to be dynamic and work with all combinations for name/value. I would love to filter these then later on to only allow certain names/measurements only...

I guess you mean you want to use the payload `name` as a key and the `value` property as its value?

In a function node:

```auto
msg.payload = {
   [msg.payload.name]: msg.payload.value
}
return msg

```

Possible via change node too with and without JSONata

Sometimes things are so simple. Thanks so much!
