Fronius

The fronius sensor polls a Fronius solar inverter, battery system or smart meter and present the values as sensors in Open Peer Power.

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

Monitored data

Each sensor type chosen as monitored condition adds a set of sensors to Open Peer Power.

  • power_flow

    Cumulative data such as the energy produced in the current day or year and overall produced energy. Also, live values such as:

    • Power fed to the grid (if positive) or taken from the grid (if negative).
    • Power load as a generator (if positive) or consumer (if negative).
    • Battery charging power (if positive) or discharging power (if negative) and information about backup or standby mode.
    • Photovoltaic production.
    • Current relative self-consumption of produced energy.
    • Current relative autonomy.

  • inverter

    Cumulative data such as the energy produced in the current day or year and overall produced energy. Also, live values about AC/DC power, current, voltage and frequency. The data is only shown when choosing device scope.

  • meter

    Detailed information about power, current and voltage, if supported split among the phases. The data is only shown when choosing device scope.

  • storage

    Detailed information about current, voltage, state, cycle count, capacity and more about installed batteries.

Note that some data (like photovoltaic production) is only provided by the Fronius device when non-zero. The corresponding sensors are added to Open Peer Power as entities as soon as they are available. This means for example that when Open Peer Power is started at night, there might be no sensor providing photovoltaic related data. This does not need to be problematic as the values will be added on sunrise, when the Fronius devices begins providing the needed data.
