FroniusSolarApi-Toolkit

Tools and libraries to help you retrieve/consume and store data from the Fronius solar API.

Getting Started

These instructions will get your clone of FroniusSolarApi-Toolkit up and running on your local machine for development.

• Download and install .NET 6.0
• cd /FroniusSolarApi-Toolkit/
• dotnet restore
• dotnet build && dotnet run --project FroniusSolarApi.Poller/FroniusSolarApi.Poller.csproj help

Components Overview

FroniusSolarApi.Poller

Usage

poller.exe fetchRealtime -c CumulationInverterData -s Console

Configuration

The FroniusSolarClient and FroniusSolarApi.Repository configuration values are stored in appsettings.json

	Description
SolarAPI_URL	The url of your Solar inverter

Example:

{
  "SolarAPI_URL": "192.168.1.102",
  "CsvConfiguration": {
    "FileLocation": "C:\\Temp",
    "FileName": "poller"
  }
}

Each data store repository has it's own configuration section see FroniusSolarApi.Repository for more details

Options

Options are case insensitive

Flag	Description	Example
-c, --collections	Required. Data collections to retrieve.	CumulationInverterData
-s, --store	Required. Where to save the data	Console
-p, --scope	(Default: Device) Query specific device(s) or whole system.	Device
-d, --device	(Default: 1) The device id to query.	1
-v, --verbose	Set output to verbose messages.	--verbose
--help	Display this help screen.	--help
--version	Display version information.	--version

You can view the poller options by running poller.exe fetchRealtime help

Scheduling

You can setup a cron schedule to automate the retrieval and storage of inverter data on Linux. For Microsoft Windows you can use Task Scheduler

CIFS/Samba file share on linux

If you would like to save the Csv file onto a CIFS/Samba share run:

• sudo apt update
• sudo apt install samba samba-common-bin smbclient cifs-utils
• sudo mount.cifs //<ip>/<share>/ /home/pi/<local> --verbose -o user=<user>,uid=1000,gid=1000

Replace uid and gid with your user id, you can find this info by running cat /etc/passwd

For more info see the Raspberry Pi documentation

Logging

By default poller logs will be saved to logs/pollerlog_{date}.txt

FroniusSolarApi.Repository

Handles storing of the inverter data returned from the FroniusSolarClient fetched using the FroniusSolarApi.Poller

Current supported data sources are listed below.

• Console - outputs the response to the console
• Csv - saves the response to a csv file
• Mssql - saves the response to a Microsoft SQL database
• Custom - you can implement your own custom data store or create an issue and i can look at adding support for the given data store in FroniusSolarApi.Repository.

Console

Prints the response to the console output. poller.exe fetchRealtime -c CommonInverterData -s Console

{
  "DAY_ENERGY": {
    "Unit": "Wh",
    "Value": 10349.0
  },
  "YEAR_ENERGY": {
    "Unit": "Wh",
    "Value": 195414.41
  },
  "TOTAL_ENERGY": {
    "Unit": "Wh",
    "Value": 195414.01999999999
  },
  "DeviceStatus": {
    "StatusCode": 2,
    "MgmtTimerRemainingTime": -1,
    "ErrorCode": 522,
    "LEDColor": 3,
    "LEDState": 0,
    "StateToReset": true
  }
}

Csv

Saves the response to a csv file. You can configure the csv settings under the CsvConfiguration section in appsettings.json

	Description
FileLocation	The location to save the csv file
FileName	This will trail the name of the csv file after the collection name for example CumulationInverterData_poller.csv

  "CsvConfiguration": {
    "FileLocation": "C:\\Temp",
    "FileName": "poller"
  }

For more information see Configuration

Mssql

Saves the response to a csv file. You can configure the mssql settings under the MssqlConfiguration section in appsettings.json

For more information see Configuration

Custom

FroniusSolarClient

The FroniusSolarClient is a .NET Client wrapper for the Fronius Solar API. Used to connect and invoke REST calls on the inverter.
