I live in a city and will be installing my Wall Connector outside in a publicly-accessible space. Is there some sort of locking feature on the Wall Connector cable that would prevent others from surreptitiously using my charger "for free" while I'm away? If not, it looks like I'd be looking at installing a ChargePoint Home charger, which would let me turn on/off the charger on a schedule (or from a phone app), so it would only be supplying volts while I'm at home and occupying the parking space. But that seems like overkill for the task -- can anyone suggest an alternate (cheaper?) charger which has an external "load management" interface that would let me easily enable/disable the charger when I'm away from home?
