The wundergroundpws platform uses Weather Underground as a source for current weather information.
Free API keys are only issued to registered and active Weather Underground personal weather station users.
To use this sensor, you need to enter your personal weather station API key and Station ID in configuration.yaml.
To get a free API key:
-
You must have a personal weather station registered and uploading data to Weather Underground
a) Join weather Underground
b) Sign In
c) My Profile -> My Weather Stations
d) Add a New PWS
-
get API key at https://www.wunderground.com/member/api-keys
Please consider this when using the following information.
To Install, copy the custom_components directory into your .homeassistant directory and the www directory into your .homeassistant directory.
or
copy the contents of the custom_components into an existing custom_components directory in your .homeassistant directory and the contents of the www directory into an existing www directory in your .homeassistant directory.
Current conditions are generated from the wundergroundpws configured pws_id.
Forecast is generated from the HA configured latitude/longitude.
To add Wunderground to your installation, add the following to your configuration.yaml file:

Note that the Weather Underground sensor is added to the entity_registry, so second and subsequent Personal Weather Station ID (pws_id) will have their monitored conditions suffixed with an index number e.g.
- sensor.wupws_weather_1d_metric_2Additional details about the API are available here.
