Hi There,

I need help to connect homey to my thermostat.  
So I have to communicate through web requests…should be easy…but I’m facing misunderstand regarding the way to use it with homey cards.  
So my request is the folowing :  
[http://192.168.x.x/conditions.cgi?token=abcdefgh](http://192.168.x.x/conditions.cgi?token=abcdefgh)  
This returns a very simple json with temperature and humidity =\> here is the complete feedback  
{  
“temperature”:23.7521,  
“humidity”:49.6349  
}

My question is : how to extract those 2 values and put them into logic variables.

I also tryed the Http Request app without any chance.

Is there someone to help me ?

Thanks in advance

That’s the app you need to use, though. What exactly did you try?

I try to do this but not sure I’m in the right way.  
So when I click on the variable I didn’t reach anything.

I also tryed to type this in http request app but the variable list still left empty… not completely sure for the path.

{“method”:“get”,“protocol”:“http:”,“hostname”:“192.168.x.x”,“path”:"/conditions.cgi",“headers”:{“token”:“tokenid”}}

The card you’re using requires the [Better Logic](https://homey.app/fr-fr/app/net.i-dev.betterlogic/Better-Logic/) app. In that app, you need to create a variable (called “variable” in your example).

Alternatively, there’s a “GET JSONpath trigger value” action (“THEN”) card available:

With that card, you can use the same URL and JSONpath expression, and let it execute a trigger (which you can name yourself, let’s say `my_trigger`).

Then in another flow, you can act on that trigger using the trigger (“WHEN”) card “JSONpath value”:

For that card, you enter the trigger name that you used in the previous step (`my_trigger`).

The card has a tag for the received value.
