The `fronius` integration polls a [Fronius](https://www.fronius.com/) solar inverter or datalogger to allow you to get details from your Fronius SolarNet setup and integrate it in your Home Assistant installation.

The Fronius integration polls a [Fronius](https://www.fronius.com/) solar inverter or datalogger for details of a Fronius SolarNet setup and integrate it in your Home Assistant installation.

|

## Prerequisites
|
||||
|
||||
You will need to either set a static IP on the Fronius device or assign a static DHCP lease for it, or alternatively access it through the local DNS name if your network is properly configured for this.
|
||||
For Gen24 devices (delivered with Firmware >= 1.14.1) make sure to activate the "Solar API" in the inverters web interface.

Note that some data (like photovoltaic production) is only provided by the Fronius device when non-zero.
|
||||
The corresponding sensors are added to Home Assistant as entities as soon as they are available.
|
||||
This means for example that when Home Assistant 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.
|
||||
When a device is not responding correctly the update interval will increase to 10 minutes (3 minutes for power flow) until valid data is received again.
|
||||
When the integration is added at night, there might be no sensors added providing photovoltaic related data. Entities will be added on sunrise, when the Fronius devices begin to provide more data.
|
||||
|
||||
When an endpoint is not responding correctly the update interval will increase to 10 minutes (3 minutes for power flow) until valid data is received again. This reduces the amount of requests to Fronius devices using night mode (shutdown when no PV power is produced).

## Energy dashboard
|
||||
|
||||
- For `Solar production`:
|
||||
- For _"Solar production"_:
|
||||
- If no battery is connected to an inverter: Add each inverters `Energy total` entity.
|
||||
- If a battery is connected to an inverter: Use [Riemann sum](/integrations/integration/) over `Power photovoltaics` entity (from power_flow endpoint found in your `SolarNet` device)
|
||||
- `Battery systems` aren't supported directly. Use [Template](/integrations/template) to split and invert negative values of `Power battery` entity (from power_flow) for charging power (W) and positive values for discharging power (W). Then use [Riemann sum](/integrations/integration/) to integrate each into energy values (kWh).
|
||||
- For `Devices` use the Ohmpilots `Energy consumed` entity.
|
||||
- If a battery is connected to an inverter: Use [Riemann sum](/integrations/integration/) over `Power photovoltaics` entity (from your `SolarNet` device).
|
||||
- _"Battery systems"_ aren't supported directly. Use [Template](/integrations/template) to split and invert negative values of `Power battery` entity (from `SolarNet` device) for charging power (W) and positive values for discharging power (W). Then use [Riemann sum](/integrations/integration/) to integrate each into energy values (kWh).
|
||||
- For _"Devices"_ use the Ohmpilots `Energy consumed` entity.
|
||||
|
||||
The energy meter integrated with Fronius devices can be installed (and configured) in two different installation positions: _"feed in path"_ (`meter_location` = 0) or _"consumption path"_ (`meter_location` = 1). In the first case, the meter provides all data you need but, in the second case, it doesn't so you need to calculate some of them by using helpers.
|
||||
The energy meter integrated with Fronius devices can be installed (and configured) in two different installation positions: _"feed in path"_ (`Meter location` = 0) or _"consumption path"_ (`Meter location` = 1).
|
||||
|
||||
### Feed in path meter
|
||||
|
||||
Recommended energy dashboard configuration for meter location in feed in path:
|
||||
|
||||
- For `Grid consumption` use the meters `Energy real consumed` entity.
|
||||
- For `Return to grid` use the meters `Energy real produced` entity.
|
||||
- For _"Grid consumption"_ use the meters `Energy real consumed` entity.
|
||||
- For _"Return to grid"_ use the meters `Energy real produced` entity.
|
||||
|
||||
### Consumption path meter
|
||||
|
||||
Recommended energy dashboard configuration for meter location in consumption path:
|
||||
|
||||
- The "Power Grid" entity provided by the Fronius API is positive on import and negative on export. Split it up into import- and export-power entities by using helpers with templates `max(states(sensor.power_grid) | float, 0)` and `max(0 - states(sensor.power_grid) | float, 0)`.
|
||||
- The `Power grid` entity provided by the Fronius API is positive on import and negative on export. Split it up into import- and export-power entities by using helpers with templates `max(states(sensor.solarnet_power_grid) | float, 0)` and `max(0 - states(sensor.solarnet_power_grid) | float, 0)`.
|
||||
- Then use [Riemann sum](/integrations/integration/) to integrate these import-/export-power entities into energy values (kWh).
|
||||
- Use these energy entities for `Grid consumption` and `Return to grid` in the energy dashboard configuration.
