-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. 
+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.
 
 ## 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.
 
-## Configuration
+{% include integrations/config_flow.md %}
-
-To enable this sensor, add the following lines to your `configuration.yaml` file:
-
-```yaml
-sensor:
-  - platform: fronius
-    resource: FRONIUS_URL_OR_IP
-    monitored_conditions:
-    - sensor_type: logger_info

-## 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:
-`http://FRONIUS_IP/solar_api/GetAPIVersion.cgi`

-## 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.
-
-```yaml
-sensor:
-  - platform: fronius
-    resource: FRONIUS_URL
