Using the new WU API
Posted: Tue 26 Mar 2019 7:25 pm
I have been using the old WU API to give me a current conditions on my webpage using my WU station's https://api.wunderground.com/weathersta ... format=XML. This included my station's data as well as some airport data such as visibility.
I had found some code on the forum and was able to incorporate in my page http://www.komokaweather.com/weather but today the data is not being shown.
Today it looks like the old API has come to an end for me.
I have been modifying the script for using my new WU API but have not been successful. I am obviously doing something wrong or missing something as the data from the json output is not showing.
My previous working script was
and this provided
I don't have a sample of the previous json file but the current json output is
My modified script with the new json data is:
Since the new API does not appear to include any external data such as visibility I may just abandon the script. However I wanted to give it a try as that may be helpful if I wanted to use any of the other information that is available with the new API.
Any pointers appreciated,
Paul

I, like the prolific group of WU contributors and users, have been excluded by the new owners of WU, IBM. They offered a token api replacement to PWS contributors that regurgitates the data that we have provided to them and a truncated forecast and no current observations from which we have received the icons to dress up our sites. There is a substantial discussion on the WU API forum. Anyway I notice that Mark has resorted to the Met Office for his forecast and current observations. Really nice display. Unfortunately the Met Office does not offer data outside of the UK. After looking around I've decided on NOAA's weather API. I've been trying to adapt the WU api call and cache but it's been a struggle, that's why I came to the forum today to see if anyone else has been successful. NOAA is using a JSON format called JSON-LD. Another promising provider is BlackSky. My 2¢!
