Hi, I plan to move to a smaller new condo and plan to setup a charging there. Basically the condo will have one flat parking and probably 8 mechanical parkings, with one car temporary space for charging (this space wasn't designed as a charging spot but I'm trying to convince the developer to). I think I can use the flat parking so there will be two charging spots there, so I would like to have one 2-port charger like WattZilla Duo. The question is, if I have one or two more EV owners to charge, how should I split the electricity cost? Seems WattZilla doesn't have a electricity meter function at all. Would it be better to have two WattZilla Uno and two meters? What do you do to split the cost in condos?
