This is driver for Weather Underground only
You need to own a pws and push data to WU to be able to get the correct (new) api key.
(Although this driver does not connect directly to your PWS.)
For apixu, you need @bangali’s driver from this thread.
Apixu.com worldwide weather data with outside lux. No PWS or server setup
When I said it was basic, I meant it does not connect directly to the PWS.
My other driver connects to a PWS via ‘weewx’ and suppliments the forecast data with data from WU.
