Hi, Long time lurker and few poster. Like everyone else I am getting ready for my Model 3. I have no garage in my house, just a driveway and a side yard with a manual gate. My plug-in hybrid stays on the driveway and I just leave my charger (110v) plugged inside the gate and the car plug outside of the gate. This has worked fine and I never find a strange car plugged in my driveway when I get home. I figure even if someone charged their car on my dime, it is not a huge loss. With Model 3 coming, I aim to upgrade the outside outlet to a NEMA14-50 but I am not so sure about the practice of leaving the plug outside. I also don't want the hassle of opening the manual gate every night to retrieve the charger or drive into the side yard. I never know what the kids leave in the side yard and would probably end up ruining many plastic toys in the dark. Is there an outside charging option with security that I can install fairly inexpensively? I would love to have something that 1) would recognize my car as "ok to charge", 2) would recognize me as "ok to use this plug" through biometrics (fingerprint swiping), or 3) would recognize me through a password. Any ideas?
