Do you plan on updating this module? Wundeground Weather now charges for their API keys.
I apologize about that and I wish I could have updated that project sooner. At the moment, we’re adding more content to the “Learn ESP32 with Arduino IDE” course.
Next, we’ll be updating the “Home Automation using ESP8266” eBook and I’ll update that example with a free API (using OpenWeatherMap.org), but that update will take a least 1… 2 months to be released.
Thanks for your interest!
