Get the state of an entity using get request (RESTful API)

Configuration
1

Greetings,

I am trying to access the state instead of an attribute of an entity. In my case it is a light. I want to curl and send a get request to grab the information of the state and store it as a JSON file. I have tried to the get request for the light correct, but I get a error 404. Again not sure if my resource link is messed up or etc .I have the api enabled and I am trying to use REST api. Below is config.yaml excerpt and a screenshot of the listed entity.

sensor:
  - platform: template
    sensors:
        light.big_room:
        friendly_name: 'Big Room'
        entity_id: 
            - light.big_room
        value_template: "{{ is.state('sensor.light.big_room.state', 'on')}}"
  - platform: rest
    sensors:
        light.big_room:
        resource: /api/states/sensor/light.big_room
        name: Big Room
        value_template: "{{ state.state('light.big_room') }}"

How about telling us what problem you are actually trying to solve, rather than your chosen solution. Because what you appear to be doing makes no sense me.

As Tom says. Why are you trying to read the state of the light using the HA Rest API from inside HA

I would like to export the state of entity into a JSON file. In this case it is the entity of the light in the big room.

Export for what purpose? To be processed by what?
