You have the option to send an OCPP reset command to zappi. Whether you perform a soft reset or a hard reset on zappi, the outcome will be the same.
However, please keep in mind that for compliance reasons, it is not possible to reboot zappi while the cable is connected to your vehicle. To reset your charger, please disconnect the cable from both your vehicle and, in the case of untethered zappis, from zappi as well.
