[APP][Pro] Alfen - Optimal Charging, Smarter Homes: Powering Efficiency for You and the Grid

You can’t start and stop charging. This is either not implemented by Alfen or nobody found the capability yet in the Alfen API. As the API is not publicly documented and all current features are reverse engineered it is not possible to implement this. You can achieve the same by setting max power very low or switch to full sun mode (if you don’t have any solar panels). This often gives not enough power to charge the car, hence, stopping the car from charging.
