I am using a RP2040 (pico w) to pull data from the weatherflow API and display the weather on an LED Matrix. The /observations/station/id api works well, however I would like to be able to use the current\_conditions from the /better\_forcast api. However, when I pull that API the json it returns for forcasts is HUGE. Are there any parameters to pull just the current\_conditions and / or just the forcast: Daily data from the api?

Example: (Scroll down to better\_forcast data)

Note: The data returned for this api is 4722 lines long (pretty formatted).

perhaps you wanted to use [https://swd.weatherflow.com/swd/rest/observations/device/xxxxxx](https://swd.weatherflow.com/swd/rest/observations/device/xxxxxx)  
where xxxxxx is your device id.

I am aware of the observations/station api, it just does not have the fields I am looking to display.  
For example:

```auto
current_conditions: {
    "conditions":xx,
    "icon": xx,
    wind_direction_cardinal: WNW,
    }

```

Granted the wind direction I could calculate, but conditions / condition icon are what I want out of the better\_forecast that is not available in the observations api.

I asked the same question not to long ago. There was a proposed solution at the bottom of the thread, but I have not yet had a chance to try it out. If you do, please reply back.

You wont be able to parse the entire json response into memory ever, but what you can do is if you know the structure, use a streaming json parser, and have it pull out the data you care about when you need it.

This is very interesting, now I just need to find something that is micropython / circuitpython compatible.

Thanks, this was really helpful!

Runs with either, I am currently using circuitpython.
