Hi all, it will be my first post, so ... GREETINGS !
I need to know how to read values from msg.payload in nodes' configuration. There is my simple flow
In function node I have very, simple code
```auto
msg.payload = {
"test": "32",
"blabla": "15"
};
return msg;
```
And question is. How use msg.payload.blabla in this below configuration field

You haven’t told us what contrib-node you are using.
But next to
Data there is `đź”»{}` does clicking here give you any other options?

Unfortunately your description doesn’t help track it down.
You installed something, most probably called node-red-contrib-XXXXX
If you look on [flows.nodered.org](http://flows.nodered.org) there are 4 with home assistant in the title.

I think it depends on if the author has written his node to pass `msg` through to the configuration node internals and specifically processes `msg` for that `data` property
In other words, it might not be possible.
In the JSONata expression, you could try....
- Accessing `payload` without `msg.`
- Accessing flow or global context vars (set before call to node)

Did A quick search for that node and I think I found the right one.
The source code shows there is help info built in to the config node (open the config node and view the info side bar).
The info says
```auto
payload.dataJSON | string
Overrides or sets the data/params property of the config.
```
So it would seem if you send ...
```auto
msg.payload = {
"data": {
"test": 33
}
};
return msg;
```
You won't need to put anything into the config node `data` field at all (it should pick up the `data` object in `payload` automatically.
Also, reading the source, it is my suspicion the JSONata expression doesn't require `msg.` part to access `payload`.

You have got right. I modified function node to that and its works
```auto
msg.payload = {
data: {
"temperature":"22"
}
};
return msg;
```

Hi,
Is it possible to pass multiple entities?
msg.payload = {
"data":{
"temperature": 22,
"entity\_id": (
"climate.danfoss\_z\_thermostat\_014g0013\_heating\_1\_8",
"climate.danfoss\_z\_thermostat\_014g0013\_heating\_1\_4"
)
}
}
return msg;

Yes, It is possible

Just in case you wanted an array and not one long string for entity\_id
```auto
msg.payload = {
"data":{
"temperature": 10,
"entity_id":[
"climate.danfoss_z_thermostat_014g0013_heating_1_8","climate.danfoss_z_thermostat_014g0013_heating_1_4"
]
}
};
return msg;
```
