JSON parsing samples

I am looking for some samples of how to parse a JSON string that I get from openweathermap.

Example JSON from here:

https://api.openweathermap.org/data/2.5/onecall?lat=-32.134014&lon=115.805813&units=metric&exclude=hourly&appid=(your app id here)

I was using XML but the 7 day weather reply is in JSON format only.

are you looking for 7 day of for 1 day ?

Actual State
https://api.openweathermap.org/data/2.5/weather?q=Perth,au&units=metric&appid=

next 5 day (for each 3 hours) on XML
https://api.openweathermap.org/data/2.5/forecast?q=Perth,au&mode=xml&appid=

turning to xml
&mode=xml
adding metric
&units=metric

Thanks for those links. I didn’t spot the XML 7 day format. I had the 1st one working and then wanted to add a 5 day forecast but only saw the JSON format. (4.3" limits me to 7 for readability)

@Dave_McLaughlin - I used openweathermap.org in my digital portal project. If you take a look at the WeatherProvider.cs class in the project below it uses JSON to process the “one call API”.

In case your interested I also built a WeatherIconProvider.cs that maps the icon code from openweathermap.org to the wi-regular.ttf font (Weather Icons - 222 font icons inspired by Font Awesome and designed for Bootstrap)). This way you can display an icon based on the open weather icon code.

Thanks Tom. I’ll be uploading my project to github when it is complete. I’ll be sure to make sure any source used has the original name included.

I have a dual 4.3" LCD SITcore for this project with one display showing time and the other the weather include 2 sensors via MQTT at my house. They communicate with each other over CAN. 2 Fez Portals could be used to run the software on but I only have wifi on one board.
