The `fronius` sensor polls a [Fronius](https://www.fronius.com/) solar inverter, battery system or smart meter and presents the values as sensors in Home Assistant. Data is gathered directly from a Fronius device connected to your local network, this integration doesn't access the cloud.
## 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.

## Finding out devices IDs
To find out the device ID of the inverter visit the URL:
`http://FRONIUS_IP/solar_api/v1/GetPowerFlowRealtimeData.fcgi`
In the returned JSON, under the key Body > Data > Inverters you should see your inverters listed with IDs starting from 1.
To find out the device ID of the meter visit the URL:
`http://FRONIUS_IP/solar_api/v1/GetMeterRealtimeData.cgi?Scope=System`
In the returned JSON, under the key Body > Data you should see your meters listed with IDs starting from 0.
To find out which API version your system runs, visit the URL:
