To enable smart management and frequency regulation of your battery, you need to have the Greenely app and an electricity contract with us. However, you can switch providers for both your electricity contract and battery management at any time. You are only committed to us for the 14-day binding period of the electricity contract. You do not need to purchase any expensive additional hardware from Greenely for us to manage your Pixii battery or other devices in your home, as we offer a solution that is controlled via our software.
