I don't know home coach. This is the only help I can provide.

Thank you very much for your help. But i need a Node or something to get the Datas from Netatmo into the Node-Red. And actually there is no working Node to get the Datas ☹

I have said it before - oauth2 is horrible. Would be nice if it could be integrated into the http request node (somehow), especially with so many applications using it today and it requires a browser for interaction with the api provider to provide scoped access.

> What I used with the old node and still miss in the new node is the ability to read public data from other Netatmo installations, which I used to get rain information in my area.

I had the same issue. Instead I installed the [node-red-oauth2](https://flows.nodered.org/node/node-red-contrib-oauth2) node, which made this relatively easy, as it provides an interface to setup the access.

Example flow (still requires one-time fiddling)

In the authorization code node provide the

clientid  
client secret

Click the key button, it will open a window to netatmo, ok for access, window will close  
now the code has been filled in, done  
deploy  
press the inject button

Access token and refresh token are saved as a global object

Now you can access the public data url (make sure to modify the url inside the function node)  
Adjust the credentials function node to refresh the token automatically every 55 mins.

Hi bakman2

thx for additional help. i will try it soon.  
Actually i am unable to install the node. I receive everytime the Failure:

Looks like it installed succesfully. Would recommend to use the node-red palette to install plugins.  
If you don't see the node, you may need to restart node-red

@bakman2

It works!!  
I had problems with generating the key (I did not realize, that the code is already filled in)  
and also in the Refresh token line the oauth2 node shows a status "`ERR_BAD_REQUEST`" when pressing inject and DBG2 says: `oauth2Response.error: invalid_client`

Another point: according to

the parameter to get only rain sensors should be `required_data=rain`  
but in your code you use `&required=${type}`!?

But I get the data I need and now I only have to integrate the new flow in my existing flow.

I had to move `msg.payload.body` to `msg.payload`, so that my existing flows continues to work.

I defined an array of types:

```auto
...
const types = ["rain", "wind"]
...
types.forEach(type=>{
    url = `${url}&required=${type}`
    node.send({headers,url})
})

```

So it makes 2 requests, one for rain and another for wind.  
Change it to:

```auto
const types = ["rain"]

```

and you will only get rain.

you will need to provide the credentials in the "credentials" function node (client\_id,client\_secret) .

I saw the code and understood it 😄

But your `&required=` should be a `&required_data=`

I thought, they can be used from the first line, but obviously they cannot be extracted out of the oauth2 node. It works now, but is there any chance to hide the client secret in the function code, maybe by filling the second oauth2 node with client\_id and client\_secret instead of "Set by msg.oauth2Request"?

Nevertheless, thank you very much for helping me / us with the oauth2 thing.

You are correct, my mistake.

Which node-red version and node js version do you use ?

Hi Guys,

thanks a lot for all the help.  
My Problem was a old version of Node Red to install the Oauth2 Node.

Now i am able to receive the right Array, but i am stil not able to work with them 😢

So my debug node shows this:  
 ![Bildschirmfoto 2023-08-09 um 19.21.12](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/5/e/5e1caf2baf3edc16ea153d4ea28e284c9e6ef0ca.png)

My function is:

```auto
var msg1 = {};

msg1.payload = msg.payload.body.devices[0].station_name;

return msg1;

```

and it doesn't work. do you see any mistake? I add this Function instead of the "debug383" in your sample.

thx

The `function` node has two outputs but only one of the outputs has a `debug` attached. Put another `debug` node on the other output.
