telegraf-kostal-modbus

Read data from Kostals Plenticore hybrid inverter and make it available as a Grafana dashboard.

Running

To run the project as is, you will need to have a running Docker-setup available. If you do not already have one, please check www.docker.com on how to get started.

Once you have Docker, starting this project is as simple as docker-compose up.

cherry-picking

If you don't want to run this project and only want to cherry-pick configurations:

Telegraf + Modbus for Kostal

Please see the folder telegraf-kostal-plenticore for the:

• Dockerfile on how to create a running telegraf with Modbus-TCP
• telegraf.conf on how to configure telegraf with Modbus-TCP for Kostal Plenticore

Grafana-Dashboard for Kostal

Please see the folder grafana/dashboards for a JSON-file containing a dashboard for the above telegraf configuration. Naming of fields with the telegraf plugin for Modbus is a little special, so the dashboard will be of no use to any other setup, i suppose.

Configuration

If you choose to run the project as-is, you can do all of the configuration in docker-compose.yaml.

• Please edit the line - "plenticore.local:10.7.77.10" so the IP matches the IP of your Plenticore.
• Please edit the two lines with - INFLUXDB_ADMIN_PASSWORD=secret to change the admin-password for influxdb

Configuring the dashboard

Once Grafana is up and running, you can reach it at Port 3000 on the IP of your Docker node (When running with Docker Toolbox on Windows, thats http://192.168.99.100:3000).

After accessing Grafana, you can also edit the contained Dashboard ("Kostal Plenticore"). To do so, please log into Grafana with the user "admin" and the password from the docker-compose.yaml line "GF_SECURITY_ADMIN_PASSWORD=secret".

• The dashboard contains variables for the price of consumption and feed in. You may want to change these
• The dashboard contains a gauge-diagram for "Erzeugung" which is by default set to "9900 Wp". Please feel free to edit this
• The dashboard is provisioned into the docker image and may not be saved. Please use "Save as" instead once to create a copy of your own

Where's the data stored?

By default, this project stores the data in so-called docker volumes. There are different ways on how to backup and restore that data.

Another useful approach is to not use volumes, but to mount directories from the host into the containers. Please see the Docker-documentation on how to do this.
