Hi, I'm new to Node Red, and have a question.

How do i filter the msg.payload output from a Tesla Node. So that I have only the output "battery\_level" value that I can send with a Mqtt node to a Domoticz Device with IDX 1

msg.payload : Object  
object  
battery\_heater\_on: false  
battery\_level: 84  
battery\_range: 249.64  
charge\_current\_request: 6  
charge\_current\_request\_max: 6  
charge\_enable\_request: true  
charge\_energy\_added: 10.29  
charge\_limit\_soc: 80  
charge\_limit\_soc\_max: 100  
charge\_limit\_soc\_min: 50  
charge\_limit\_soc\_std: 90  
charge\_miles\_added\_ideal: 42

Regards Robin

Hi Robin and welcome to the forum.

On this particular question (getting values from a message) - there’s a great page in the docs that will explain how to use the debug panel to find the right path to any data item.

[https://nodered.org/docs/user-guide/messages](https://nodered.org/docs/user-guide/messages)

To answer your immediate question, i would use a `change` node to `set` `msg.payload` to `msg.payload.battery_level` then connect the `change` node to an `MQTT out` node (with appropriate topic set).

As you are new to node-red - I highly recommend watching this playlist: [Node-RED Essentials](https://www.youtube.com/playlist?list=PLyNBB9VCLmo1hyO-4fIZ08gqFcXBkHy-6). It is by the developers of node-red. They're nice & short and to the point. You will understand a whole lot more in less than an hour. A small investment for a lot of gain.

Hi, thanks for info.

A node red flow example would be welcome

Thanks Robin

Hi again,

Its covered in that first link i posted under the heading [changing-message-properties](https://nodered.org/docs/user-guide/messages#changing-message-properties)

And it really is as simple as I said: Attach a `change` node to your `MQTT in`, set `msg.payload` to `msg.payload.battery_level` link that to an `MQTT out` node

TBH, this is one of the most basic and fundamentals of node-red. You would do yourself a great favour watching that playlist (and perhaps work your way through the [cookbook](https://cookbook.nodered.org/))
