Hello  
I have a output from a energy meter. I can send it to a mqtt broker. But how do i switch the object info from the meter node to diffrent messageses.

I'm intrested inn the values from:

react\_pow\_neg:  
curr\_L1:  
curr\_L2:  
curr\_L3:  
volt\_L1:  
volt\_L2:  
volt\_L3:

```auto

I'm not sure what this `Kamstrup` node is or does.

Where are you seeing/getting the output you posted? (Which node)  
[![](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/0/3/03896615dc92e3ea3034577f3a45db523303b42e.png) ](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/0/3/03896615dc92e3ea3034577f3a45db523303b42e.png)

Let's start there.

I'm guessing the next step will be the `split` node to split the message.  
Then, we can start rearranging things to suit needs.

Hello.  
the kamstrup node is a mbus/HAN port converter to get energy values from the energy meters in Norway. node-red-contrib-ams-decoder

I found out that I can use a debug output and use 'msg.payload.curr\_L2' then I get the rigth value.  
So the next is to get it to send values to the influx database I have.  
I get errors

I have setup the node red influxdb with the same adresses and passwords as I use with InfluxDB Studio

But the logg gives me error  
Apr 10 03:15:13 piUNFI Node-RED[22342]: 10 Apr 03:15:13 - [error] [influxdb in:20e9f519.e400c2] Error: Request timed out  
could it be somting with IP4 vs IP6?

sorry, but any/all database programs are way WAY out of my scope of knowledge.

And I have no knowledge of this _mbux/HAN_ thing.

Sorry. I'm still learning. (Or trying to)

I'm trying to learn to 🙂  
Thank you for taking the time to replay. I will post more as I get things working, Maby more people can learn from it

Instead of "switching", use a change node to "extract" the info you are interested in.

Note that most output-nodes can read the values directly in the same manner.  
In the debug node you could also use payload.curr\_L1 and see the output for example.
