How to create multiple sensors from my json return data

Configuration
1

I’ve created a RESTful sensor:

rest:
  - scan_interval: 60
    resource: http://192.168.1.114:8080/
    sensor:
      - name: "Heatmaster Boiler"
        json_attributes_path: "$.Heatmaster"
        json_attributes:
          - "status"
          - "temp"
          - "O2"
          - "Top_Air"
          - "Bottom_Air"

I get the data into HA I can see them in the developers->states listing. I can see them in the Heatmaster sensor as attributes.

What I really want is a separate sensore for each attribute. From reading it sounds like I need to use a template to do this? I’ve no idea how.

Any suggestions, pointers on how to create multiple sensors?

thanks

Like this:

rest:
  - scan_interval: 60
    resource: http://192.168.1.114:8080/
    sensor:
      - name: "Heatmaster Boiler Status"
        state: "{{ value_json.Heatmaster.status }}"
      - name: "Heatmaster Temperature"
        state: "{{ value_json.Heatmaster.temp }}"
      - name: "Heatmaster O2"
        state: "{{ value_json.Heatmaster.O2 }}"
      - name: "Heatmaster Top Air"
        state: "{{ value_json.Heatmaster.Top_Air }}"
      - name: "Heatmaster Bottom Air"
        state: "{{ value_json.Heatmaster.Bottom_Air }}"

You can add unit of measurement or device classes to any that require it. Also if there are any binary sensors (on/off) put them under binary_sensor: rather than sensor: and adjust the template to return true or false.

Well I screwed something up:

Invalid config for [rest]: [state] is an invalid option for [rest]. Check: rest->rest->0->sensor->0->state. (See /config/configuration.yaml, line 83).

The only thing on line 83 is: rest:

I just had to change state: to value_template: and it works!

rest:
  - scan_interval: 60
    resource: http://192.168.1.114:8080/
    sensor:
      - name: "Heatmaster Boiler Status"
        value_template: "{{ value_json.Heatmaster.status }}"
      - name: "Heatmaster Temperature"
        value_template: "{{ value_json.Heatmaster.temp }}"
        device_class: temperature
        unit_of_measurement: '°F'      
      - name: "Heatmaster O2"
        value_template: "{{ value_json.Heatmaster.O2 }}"
      - name: "Heatmaster Top Air"
        value_template: "{{ value_json.Heatmaster.Top_Air }}"
      - name: "Heatmaster Bottom Air"
        value_template: "{{ value_json.Heatmaster.Bottom_Air }}"

Opps. Sorry, should have looked it up in the docs instead of doing it from memory. state: is for the new template sensor format, not the new rest sensor integration.
