Some time ago I found this https://github.com/paprins/omnik-data-logger/ at github. A python based project to read out the statistics from https://www.omnikportal.com/. I own an inverter of Omnik (Omniksol-3.0-TL) and was installed october 2012. Pascal Prins, the author implemented a plugin based logger with a working example for pvoutput.org.
Pascals code had some issues, and I decided to report them. In de mean wile I went on with a clone copy of the project, fixed some issues and optimized the code.
AppDaemon and Home Assistant integration with MQTT
I wrote an additional plugin (mqtt) to enable an easy integration with Home Assistant or any other MQTT based home automation solution.
The AppDaemon integration further enables updating the config without the need to restart.
New version at github
After integration with AppDaemon I ended up with an alternative that can be configured with AppDaemon through apps.yaml. The logging was adapted so it supports the AppDaemon logging system. When using the command line native logging is used.
I submitted the new code to github and did a pull request.
Using MQTT Auto discovery logging now can be easily integrated with Home Assistant.
