Honestly they are placeholders, just to show what you could do with the card.
However, different weather integrations will hook you up with sensors for wind speed.
As for the sun, what I personally did is make some template sensors to get the azimuth and elevation from the default sun entity in Home Assistant. Here is the yaml to put in your configuration.yaml
for that:
sensor:
- platform: template
sensors:
solar_angle:
friendly_name: "Elevation"
unit_of_measurement: '°'
icon_template: "mdi:axis-y-rotate-clockwise"
value_template: "{{ state_attr('sun.sun', 'elevation') }}"
solar_azimuth:
friendly_name: "Azimuth"
unit_of_measurement: '°'
icon_template: "mdi:axis-z-rotate-clockwise"
value_template: "{{ state_attr('sun.sun', 'azimuth') }}"
Then you can use sensor.solar_elevation
and sensor.solar_azimuth
in your card.
Extra note, the sun entity only gives valid values for your location when you set the correct location in the Configuration->General
settings.
