Yes, it can be used to access WU.
That’s strange, on the website it is $19.99…?
Did you try enabling PWS on our weather station chooser? If you haven’t, there could be a lot of closer stations.
We also support Netatmo out of the box with pwsweather.com (our current provider)
Once our new software platform is released this year, we want to grow our PWS footprint
Hope this helps, let us know if you have any other questions. Thanks and have a great day.
