About this app
Discover the clever way to use solar power or dynamic electricity tariffs to reduce your energy costs!
Free PV Forecast
Use our AI-powered forecast function to display your remaining solar power production daily for free. This allows you to optimally plan your consumption and use your energy more efficiently.
Storage Control
Optimize the use of your battery storage with selected manufacturers: Charge it at particularly favorable times or stop discharging while your car is charging. In combination with the PV forecast, we control your storage system to achieve maximum savings.
Automation based on dynamic electricity prices
Benefit from our price-signal-enabled control system to benefit from dynamic electricity exchange prices and reduce your energy costs by automatically controlling consumers during low-cost hours.
Maximize Your Self-Consumption
With our application, you can easily use the solar power generated by your photovoltaic system efficiently. Increase your self-consumption instead of feeding the surplus into the public grid.
Optimize your electric car charging
Use the app to intelligently charge your electric car using surplus solar power or dynamic electricity prices, saving money and contributing to sustainable mobility.
No investment required
