There are three WindGuru related plugins available here:
Getting the windguru forecast codes.
The plugin system will only work if you have registered with windguru and have created favourite forecasts in your windguru account.
- Register with Windguru: If you are not already registered with Windguru go to https://www.windguru.cz/int/novy.php
- Login to your account.
- Go to Settings > Forecasts for your Websites.
- You are able to add up to 10 spots – either click on Add Another Spot or select one from those you have previously created.
- In the forecast preview you will see the forecast followed by some code. You want the two numbers located inside the php code.
- Place these numbers inside the plugin call as explained for each plugin.
I owe a huge thanks to Vaclav Hornik for his support and letting me publish these plugins
