SP Weather does not work for me in Joomla. I get the following error message: "Please make sure that, your allow_url_fopen or cURL is enabled. Also, make sure your API key and location is correct. Verify your location from here https://openweathermap.org/find", but these settings are enabled and the API key is also correct. A separate direct call to Openweather works without any problems.
