Successful, easy charge. I used my ChargePoint RFID card, but it appears it’s equally simple to initiate using this app. I uploaded a pic that’s marked up to indicate which 2-plug charger set is free, and which is .20/kwh—because they appear identical and there doesn’t seem to be any noticeable external identifier (eg., easily-discernible unit ID #) apart from pricing menu on charger screen.
