Accessing remote HA with miflora sensor using REST

Third party integrations
1

Hello, I’m a newbie using MiFlora bluetooth sensors that have limited reach and my HA doesn’t pick them up. I installed a RPI zero W in the same room as the sensors using the HA image and connected the sensors to that. So far so good.

On my primary HA, I’m now trying to setup a remote sensor using a REST sensor in such a way that the primary PI only has to do one REST call to pull all the values, but I’m struggling to get it to work. Whatever I try, the sensors show up as unavailable. Here’s the structure that the api/states call returns:

[
  {...},
  {...},

  {...},
  {...},
  {...},
  {...},
  {...},
  {...},
  {...},
  {...},
  {...},

  {...}
],

Here's the config on my primary HA:
 - platform: rest
    resource: http://192.168.1.111:8123/api/states
    headers:
      Authorization: !secret pizero_api_token
    name: pizero
    value_template: '{{ value_json }}'
    json_attributes: '{{ value_json }}'

  - platform: template
    sensors:
      miflora2_moisture:
        value_template: '{{ states.sensor.pizero[3].state }}'
        friendly_name: "Lemon Moisture"
        unit_of_measurement: '%'
      miflora2_light_intensity:
        value_template: '{{ states.sensor.pizero.attributes[4].state }}'
        friendly_name: "Lemon Light intensity"
        unit_of_measurement: 'lx'

I’m probably going the wrong way about this, so if I should use a completely different way to achieve my goal, please let me know. Thanks!
