Sensor from JSON, attribute with EPOCH time

Configuration
1

Hi,

New user so forgive my ignorance.

I have a sensor like this:

image1075×83 3.83 KB 

sensor:
      - name: "Uno-X Fossen"
        json_attributes_path: "$..[?(@.name=='Uno-X Fossen')].stationDetails..[?(@.type=='95')]"
        value_template: "{{ state_attr('sensor.uno_x_fossen', 'price') }}"
        force_update: true
        json_attributes:
          - "price"
          - "lastUpdated"

Now I’m trying to use the attribute lastUpdated in a card. But I don’t know how to convert this into a local time and use it in cards. Any pointers?
