Wireless bridge 550-00640

[Pitsaer]

Hello,

I just purchased the 550-00640 wireless bridge to read port P1 on my electricity meter, to which my digital gas and water meters are connected wirelessly.

I can see my three meters in the NHC2 software and my various consumption data in the Niko Home app.

Is it possible to retrieve all the information on H.A.?
Thank you.

See #247

I saw this topic, but I don't understand how to implement it 🫤

I tried this:

sensor:

  - platform: rest
    name: “Niko Gas Volume”
    resource: “http://192.168.x.xx/api/v1/measurements”
    method: GET
    headers:
      authorization: “Bearer MY_TOKEN”
    value_template: “{{ value_json.GasVolume }}”
    unit_of_measurement: “m³”

  - platform: rest
    name: “Niko Water Volume”
    resource: “http://192.168.x.xx/api/v1/measurements”
    method: GET
    headers:
      authorization: “Bearer MY_TOKEN”
    value_template: “{{ value_json.WaterVolume }}”
    unit_of_measurement: “m³”

But the sensors appear with an unknown status, so it doesn't work.

You are surely not calling the right endpoints.
I strongly suggest you first check the Postman collection and use that to see what data is present.

@Pitsaer This should work:

sensor:
  - platform: rest
    name: Gas Volume
    resource: https://NIKO<4 last characters of MAC>.local/measurements/v1/devices/<uuid of energyhome>
    method: GET
    verify_ssl: false
    headers:
      Authorization: "Bearer <your hobby API token>"
    value_template: >-
      {% set gas = value_json.Properties
          | selectattr('Property','eq','GasVolume')
          | map(attribute='Values')
          | list %}
      {% if gas and gas[0] and gas[0][0] is defined %}
        {{ gas[0][0].Value }}
      {% else %}
        unknown
      {% endif %}
    unit_of_measurement: "m³"
    device_class: gas
    state_class: total_increasing
    scan_interval: 300
    
  - platform: rest
    name: "Water Volume"
    resource: https://NIKO<4 last characters of MAC>.local/measurements/v1/devices/<uuid of energyhome>
    method: GET
    verify_ssl: false
    headers:
      Authorization: "Bearer <your hobby API token>"
    value_template: >-
      {% set water = value_json.Properties
          | selectattr('Property','eq','WaterVolume')
          | map(attribute='Values')
          | list %}
      {% if water and water[0] and water[0][0] is defined %}
        {{ water[0][0].Value }}
      {% else %}
        unknown
      {% endif %}
    unit_of_measurement: "m³"
    device_class: water
    state_class: total_increasing
    scan_interval: 300

Replace all text between <> with your own system values.

It also should be possible to do this with one API call but I haven't had the time for changing that.

Probably #263 is relevant. Or should be updated if this is implemented.
