Fronius	Instructions on how to connect your Fronius Inverter to Home Assistant.	Energy Sensor	fronius.png	Local Polling	0.96

The fronius sensor will poll a Fronius solar inverter, battery system or smart meter and present the values as sensors (or attributes of sensors) in Home Assistant.

Configuration

To enable this sensor, add the following lines to your configuration.yaml file:

sensor:
  - platform: fronius
    resource: FRONIUS_URL
    monitored_conditions:
    - sensor_type: inverter

{% configuration %} resource: description: "The IP address of the Fronius device" required: true type: string monitored_conditions: description: "Conditions to display in the frontend" required: true type: list keys: type: description: "The kind of device, can be one of "inverter", "storage", "meter", or "power_flow"" required: true type: string scope: description: "The device type for storage and inverter, can be either "device" or "system"" required: false type: string default: "device" device: description: "The id of the device to poll" required: false default: ""1" for inverters and "0" for other devices such as storages in compliance with Fronius Specs" {% endconfiguration %}

Examples

When including more of the components that one Fronius device offers, a list of sensors that are to be integrated can be given like below.

sensor:
  - platform: fronius
    resource: FRONIUS_IP_ADDRESS
    monitored_conditions:
    - sensor_type: inverter
      device: 1
    - sensor_type: meter
      scope: system
    - sensor_type: meter
      device: 3
    - sensor_type: storage
      device: 0
    - sensor_type: power_flow

Sensors configuration

To extract more detailed values from the state of each integrated sensor and to circumvent undefined values, it is recommended to use template sensors as an interface:

{% raw %}

- platform: template
  sensors:
    electricity_inverter1_power_netto:
      unit_of_measurement: 'W'
      value_template: >-
        {% if states.sensor.fronius_1921684247_inverter_1.attributes.power_ac is defined -%}
          {{ states_attr('sensor.fronius_1921684247_inverter_1', 'power_ac') | float | round(2) }}
        {%- else -%}
          0
        {%- endif %}
    electricity_autonomy:
      unit_of_measurement: '%'
      value_template: >-
        {% if states.sensor.fronius_1921684247_power_flow.attributes.relative_autonomy is defined -%}
          {{ states_attr('sensor.fronius_1921684247_power_flow', 'relative_autonomy') | float | round(2) }}
        {%- else -%}
          0
        {%- endif %}

{% endraw %}
