How to get multiple sensors for 1 rest call?

[michel72 (Michel - espthings.io)]

Hi,

I’m stying to get multiple sensors from 1 rest call as the API of my device does not seem to like multiple calls to it’s API

Right now I have configured this:

The rest call http://192.168.207.98/getParameters replies with:

{"type":"parameters","list":[{"vehicleState":2,"evseState":false,"maxCurrent":20,"actualCurrent":18,"actualPower":0,"duration":0,"alwaysActive":false,"lastActionUser":"","lastActionUID":"","energy":0,"mileage":0,"meterReading":0,"currentP1":0,"currentP2":0,"currentP3":0}]}

sensor:
  - platform: rest
    name: EVSE Vehicle state
    resource: http://192.168.207.98/getParameters
    value_template: "{{ value_json.list[0].vehicleState }}"
    method: GET
    timeout: 30
    force_update: true

  - platform: rest
    name: EVSE state
    resource: http://192.168.207.98/getParameters
    value_template: "{{ value_json.list[0].evseState }}"
    method: GET
    timeout: 30
    force_update: true

  - platform: rest
    name: EVSE Actual current
    resource: http://192.168.207.98/getParameters
    value_template: "{{ value_json.list[0].actualCurrent }}"
    unit_of_measurement: "A"
    method: GET
    timeout: 30
    force_update: true

How could I combine those 3 (or preferably all parameters) into one call?

You can use json_attributes to add other values to attributes in one sensor and then use template sensors for them.

Thanks, I found this in another topic, and tried to get it to work for my specific use case, but sofar no luck. Do you have an example for my sensors maybe?

sensor:
- platform: rest
    name: csensor
    resource: http://10.161.0.130:2001/sensors
    json_attributes:
    - temperature
    - humidity
    - battery
    - timestamp
- platform: template
    sensors:
    temperature:
        value_template: '{{state.sensor.csensor.bedroom1.attributes["temperature"]}}'

Specify a json attributes path.

sensor:
- platform: rest
    name: csensor
    resource: http://10.161.0.130:2001/sensors
    json_attributes_path: $.list[0]
    json_attributes:
    - currentP1
    - currentP2
    - currentP3
    - etc...

Thank you. That was it:

sensor:
  - platform: rest
    resource: http://192.168.207.98/getParameters
    name: evse
    value_template: 'OK'
    json_attributes_path: $.list[0]
    json_attributes:
      - vehicleState
      - evseState
      - maxCurrent
      - actualCurrent
      - actualPower
      - duration
      - alwaysActive
      - lastActionUser
      - lastActionUID
      - energy
      - mileage
      - meterReading
      - currentP1
      - currentP2
      - currentP3
  - platform: template
    sensors:
      evse_vehiclestate:
        value_template: "{{ state_attr('sensor.evse', 'vehicleState') }}"

Hello,

I am trying to read multiple sensors for 1 rest call. It works when I do one rest call to get one sensor via value_json.list[28]. How could I make more sensors it they only differ by number in [ ]?

Thank you for your help

[tom_l]

Use the new rest integration.

rest:
  - authentication: basic
    username: "admin"
    password: "password"
    scan_interval: 60
    resource: http://192.168.1.12/status.xml
    sensor:
      - name: "Sensor 1"
        value_template: "{{ value_json.list[28] }}"
      - name: "Sensor 2"
        value_template: "{{ value_json.list[29] }}"
      - name: "Sensor 3"
        value_template: "{{ value_json.list[30] }}"
      etc...

RESTful

For anyone looking here’s my setup for the following json response:

{
    "bedroom_shades": {
        "state": 0,
        "position": 0,
        "tilt_position": 0
    },
    "kitchen_door_blinds": {
        "state": 0,
        "position": 100,
        "tilt_position": 0.0
    },
    "bedroom_blinds": {
        "state": 0,
        "position": 0,
        "tilt_position": 100.0
    },
    "living_room_door_blinds": {
        "state": 0,
        "position": 0,
        "tilt_position": 64.44444
    }
}

The sensor configuration is as follows:

rest:
  - resource: http://192.168.0.123/getState
    scan_interval: 30
    method: GET
    verify_ssl: false
    headers:
      accept: "application/json"
      content-type: "application/json"
    payload: '{ "type": "get" }'
    sensor:
      - name: "bedroom_blinds"
        value_template: "OK"
        json_attributes_path: "$.['bedroom_blinds']"
        json_attributes:
          - position
          - state
          - tilt_position
      - name: "bedroom_shades"
        value_template: "OK"
        json_attributes_path: "$.['bedroom_shades']"
        json_attributes:
          - position
          - state
          - tilt_position
      - name: "kitchen_door_blinds"
        value_template: "OK"
        json_attributes_path: "$.['kitchen_door_blinds']"
        json_attributes:
          - position
          - state
          - tilt_position
      - name: "living_room_door_blinds"
        value_template: "OK"
        json_attributes_path: "$.['living_room_door_blinds']"
        json_attributes:
          - position
          - state
          - tilt_position

And I can see correct data in Developer tools

You should use the value_template for the state, rather than just printing the text “OK” no matter wat at.
