I had the same issue… although I don’t remember quite well, I think I solved it with installing this addon. It is also available in HACS, if you use it and don’t like manual installation.
It has something to do with changed API key checking process, I believe, that’s why native WUnderground integration returns errors
Well, if you installed the addon from my link, than you must also change the platform in configuration.yaml - for this addon it is “wundergroundpws”, while the default (which you have) is “wunderground”…
here’s my layout now in the config I got no errors in logs but still not showing up on h a
also do I need to add this sensor.wupws_weather_1d_metric_2 where it says sensor
thanks Oliver
For all these lines the sensors are automatically created, for example the line
“- humidity”
creates
“sensor.wupws_humidity”
and so on. You don’t need to create any additional sensors.
I did this To Install, copy the custom_components directory into your .homeassistant directory and the www directory into your .homeassistant directory.
