Add sensor domain as an allowed entity for use with card.

[jazzyisj]

The forecast entity is going to be deprecated soon in weather templates. The solution to this is to create a separate template entity with a forecast attribute using the weather.get_forecasts service. Using a sensor like this with this card works perfectly except the following error appears in the home assistant log.

ERROR (MainThread) [homeassistant.components.websocket_api.http.connection] [281471474635328] Error handling message: Entity ID 'sensor.hourly_weather2' does not belong to domain 'weather' for dictionary value @ data['entity_id'].

This is my sensor template..

template:
  - trigger:
      - platform: homeassistant
        event: start
      - platform: event
        event_type: event_template_reloaded

      - platform: state
        entity_id: &forecasts
          - weather.windsor
          - weather.pirateweather
          - weather.forecast_home
        from:
          - unknown
          - unavailable
    action:
      - service: weather.get_forecasts

    sensor:
      - name: "Hourly Weather2"
        unique_id: hourly_weather2
        state: "{{ now() }}"
        attributes:
          forecast: >
            {% if hourly is defined %}
              {% if hourly['weather.pirateweather'] is defined
                  and hourly['weather.pirateweather']['forecast'] is defined %}
                {{ hourly['weather.pirateweather']['forecast'] }}
              {% elif hourly['weather.forecast_home'] is defined
                  and hourly['weather.forecast_home']['forecast'] is defined %}
                {{ hourly['weather.forecast_home']['forecast'] }}
              {% elif hourly['weather.windsor'] is defined
                  and hourly['weather.windsor']['forecast'] is defined %}
                {{ hourly['weather.windsor']['forecast'] }}
              {% endif %}
            {% endif %}
