You can use a template sensor that references the attribute of your weather component to achieve that. You’ll want to confirm the entity_id of your weather component and that the temperature attribute is named temperature.
Here’s an example of what I would need based on my weather component:
sensor:
- platform: template
sensors:
weather_temperature:
friendly_name: "Weather Temperature"
unit_of_measurement: 'degrees'
value_template: "{{ state_attr('weather.local_weather', 'temperature') }}"
