Fronius Energy Consumption

Access PV live logs using the Fronius Solar API V1 and sends the values to an influx db.

Description

Java programm which reads the current power production of the fronius symo inverter. It sends the values to an influx db (the influx API v2 is used, which is compatible with Influxdb2 and Influxdb 1.x).

Features

Via Environment Variable (SHELLY.PLUGS.MANAGING) you can activate the management of shelly relays, to switch on or off e.g. the Shelly PLUG-S component. If the flag is active and the production is over the POWER.THRESHOLD value, it switches on the relay - if it goes down under the threshold, it switches the component off.

Shelly Plug-S

Docker Image

You can find the Docker image on Docker Hub

If you want to run a container, you can use the command docker run pendl2/fronius-reader

There are different tags available for common processor architectures:

  • latest
  • the project-version itself

Configuration

Docker Environment Variable Default Description
FRONIUS.HOST fronius The host where, the Fronius API is running
SHELLY.PLUGS shelly-plug-s-1 The Shelly PlugS host address
SHELLY.PLUGS.MANAGING false Flag to activate or deactive the shelly plugs
POWER.THRESHOLD 3500 Long value in Watt. If threshold is reached, it activates the Shelly Plug-S component
LOG.LEVEL INFO Log Level, can be switched to debug, for detailed information
INFLUXDB.HOST localhost The host where the influx service is running
INFLUXDB.PORT 8086 The port where the service is running
INFLUXDB.BUCKET home The bucket
INFLUXDB.ORG pendulum The organisation which is sent to the InfluxDB
INFLUXDB.USER.TOKEN If this environment is set, the token will be added to the request, if not, no authentication is used

Example: setting the host 0.0.0.0 via environment: sudo docker run -e FRONIUS.HOST=0.0.0.0 pendl2/fronius-reader

Multi-Container Configuration

I created a multi-container configuration, which contains:

  • InfluxDb
  • Grafana
  • Fronius Energy Consumption (this project)

You can find the details in the following repo: Multi Container Project

You can easily define dashboards with grafana, here is an example of my dashboard:

Open Points:

  • Integrate the Shelly 3em energy meter
