PowerSignal App:

The Energy-Charts.info PowerSignal is designed to make it easier to adjust consumption to current generation.
The share of renewable energies in the electrical load is used as the basis for this.
Alternatively, the day-ahead exchange electricity price can also be used as the data basis.
In addition to the app, widgets are also offered to provide all the necessary information at a glance.

For Android we also offer a direct download of the APK file:
