I get stuck trying to read the temperature sensors connected to ngenic.  
I’ve found the token and room and sensor uuid and get a CURL GET to work on my MAC in terminal.

But I don’t get it how to translate that to a HTTP GET in Homey…  
Any suggestions??

curl command  
curl -X GET  
-H “Authorization: Bearer abcd1234PRIVATETOKENabcd1234”  
“[https://app.ngenic.se/api/v3/tunes/{f3e2e629-8eb9-ec11-997e-e42aac6e0f30}/measurements/{0687242c-75cc-ec11-997e-e42aac6e0f30}/latest?type=temperature\_C](https://app.ngenic.se/api/v3/tunes/%7Bf3e2e629-8eb9-ec11-997e-e42aac6e0f30%7D/measurements/%7B0687242c-75cc-ec11-997e-e42aac6e0f30%7D/latest?type=temperature_C)”

response:  
{“hasValue”:true,“time”:“2022-09-20T16:25:28 Europe/Stockholm”,“value”:21.5625}%

were “value” is the current temperature.

The problem is it isn’t a proper json file. The quotation marks should be " and not “. A slight problem but that’s the reason it doesn’t work. The json file should be like this:

 ![2022-09-22](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/3/c/3c146e46cb7a37451ed595eae812044dac618692.png)

if you have the option to download a proper json file it will work otherwise you have to adjust the file.

Maybe you have a method to adjust this file on your computer, otherwise it is maybe possible to adjust the file wirh homeyscript

I believe there is still a problem with the GET function…  
Since I don’t get a reply in Homey only error… There is something with the syntax of the GET command I think…

That’s what the `</>` button is for 😉

```auto
{
    "hasValue":true,
    "time":"2022-09-20T16:25:28 Europe/Stockholm",
    "value":21.5625
}

```

@Roger_Levenrot  
But not showing what you already have as “get” flow cards is kinda difficult to say what is wrong.

You have to use the [“HTTP request flow cards” app](https://homey.app/a/com.internet/), which allows you to extract values from a JSON response (just don’t ask me how to use it 😅).

Haven’t used the http app in a while, the build in logic send http card had seperate inputs for URL, body and headers, when I’m at home I can give you an example.

You can’t extract content from the responses with the built-in Logic card.

As long as the response is JSON, yes you can, with Homey advance flows it is really easy.

</div>

this should do it:

 ![numver value JSON](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/3/d3837aa051b188d155cfae9f0e34967a38fb7e28.jpeg)

```

Header:

```auto
{ "authorization":"Bearer XYXYMYTOKENXYXY", "content-type":"application/json" }

```

Edit:  
if you want to be safe (if their service is offline for example, kinda forgot to add it into the example flow), you can add another “AND” card between the request and reading the JSON, and see if the “status code” (number) is `200`  
 ![status 200](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/3/a/3a951d400357544c9ea99350d7568bf72aa91c14.jpeg)

The issue is that the example is showing the headers in JSON format, while they should be in plain text (with line breaks in between the different headers).
