Piekpiloot, a Dutch controller for home batteries
Piekpiloot is a plug-in controller for a Marstek Venus home battery, using dynamic electricity prices, solar forecasts and household consumption to plan charging.
- For
- Marstek Venus owners with dynamic electricity contracts
- Worth noticing
- It accounts for roughly one-sixth energy loss in battery cycling and stays on Auto when price spreads cannot cover it.
Field notes
The described controller uses a local network connection to a Marstek Venus battery and a P1 meter, while retrieving prices and solar forecasts online. Its screen shows energy flows, quarter-hour prices, forecasts and planned battery behavior; the same information is said to be available on a web page within the home network. The page labels its savings figures as examples and explains that flat-price days may produce no worthwhile grid-charging opportunity.
