I created a module that visualizes produced, stored and consumed energy in your house in a minimalistic way.

It is meant to be used when you have a solar plant and an energy storage system (optional) installed.

How it works

The module relies on other modules that provide data for it. It gets data updates via notifications from these “data source” modules.

Depending in which direction the power flows, the arrows change and current values are updated.

I developed MMM-VartaESS for Varta Energy Storage Systems and MMM-Fronius2 for Fronius power converters as companion modules for this to provide the necessary data.

The README in the GitHub repo explains, how to send data updates.

Hey guys, I have good news for you:

Commit 8c5e69f in the GitHub repo implements the one direction feature feature via the directionStationId variable. You just enter the next station on your line for the direction you want the departures to be shown.

Some words about that:

After some tests, the data delivery of this feature seems not to be as reliable as the normal version. Also, please make sure you actually have the right stationId for the direction station.
Additionally, more request results take more time for the request. So please make sure to keep your maxUnreachableDepartures and maxReachabledepartures low when using this feature.

If you encounter any issues with that, please open an issue on GitHub.

I also mentioned this in the readme. Thanks again to @derhuerst for implementing the feature in his service!
