Create Weather Warning ⛈

Create weather warning alerts and maybe use it to drive some of the modes like the lockdown mode in #35

Using feedparser to get weather warning via RSS from the met office 927017c

There are 2 UI methods I use to both using custom integrations / front end from HACS.

First method using Mushroom to show a chip:

type: custom:mushroom-chips-card
chips:
  - type: conditional
    conditions:
      - entity: sensor.met_office_rss_weather_warnings
        state_not: '0'
    chip:
      type: weather
      entity: weather.openweathermap
      show_conditions: true
      show_temperature: true

When there is 1 or more entries in the RSS for my area, it will show a chip with the OpenWeatherMap.

The other method is to use auto-entities to show when there is 1 or more events in the RSS:

type: custom:auto-entities
card:
  type: custom:mushroom-template-card
  primary: >-
    {{ state_attr('sensor.met_office_rss_weather_warnings', 'entries')[0].title
    }}
  secondary: ''
  icon: mdi:weather-cloudy-alert
  fill_container: false
  icon_color: yellow
filter:
  include:
    - entity_id: sensor.met_office_rss_weather_warnings
      state: '> 0'
show_empty: false
sort:
  method: state
  ignore_case: true

It uses Mushroom template card to show the RSS warning message. The Mushroom template card gives more control so I have used a yellow background to highlight the weather warning message.
