How to set the correct attributes path in these Rest en Command_line sensors

[Mariusthvdb (Marius)]

failing to see the correct structure, please help me out here:

sensor:
  - platform: rest
    name: Iungo firmware
    resource: !secret iungo_url
    method: POST
    payload: '{"seq":1, "method":"fw_get_remote_info"}'
    value_template: >
      {{value_json.rv.fw.version}}
    json_attributes_path: > #also tried {{value_json.rv.fw}}
      $.[3].fw
    json_attributes:
      - date
      - status
      - build
      - version
    scan_interval: 86400

  - platform: command_line
    name: Iungo firmware cmd
    command: >
      curl -X POST -d '{"seq":1,"method":"fw_get_remote_info"}' http://192.168.1.27/iungo/api_request
    value_template: >
      {{value_json.rv.fw.version}}
    json_attributes:
      - date
      - status
      - build
      - version
    scan_interval: 86400

both result in the correct value_template, but both fail to set the attributes.
this is the output of the curl command:

curl -X POST -d '{"seq":1,"method":"fw_get_remote_info"}' http://192.168.1.27/iungo/api_request
{"ok":true,
 "type":"response",
 "time":0.61230495500058,
 "rv":{"fw":{"date":"Fri Aug 21 16:01:24 CEST 2020","status":"","version":"1.5","build":"3638"}},
 "systime":1605363708,
 "seq":1,
 "error":false}

thanks for having a look!

using $.rv.fw is supposed to bring me to the correct path,

but doesnt work either, it simply doesnt return any attribute

[petro]

Your path is $.rv.fw. You’re most likely running into some other issue.

yeah thanks
Any thoughts on an issue? I’ve set error level to debug

homeassistant.components.rest.sensor: debug

and nothing is returned.

also, how could I get to the attributes using the command_line sensor? where does that pickup from, since there is no way to set a path ?

update:

Changing to a single line for the attributes_path did the trick:

sensor:
  - platform: rest
    name: Iungo firmware
    resource: !secret iungo_url
    method: POST
    payload: >
      {"seq":1, "method":"fw_get_remote_info"}
    value_template: >
      {{value_json.rv.fw.version}}
    json_attributes_path: $.rv.fw
    json_attributes:
      - date
      - status
      - build
      - version
    scan_interval: 86400

returns nicely:

now how to get that in the command_line sensor…
