I'm in NY City for the Thanskgiving holiday and need to charge my Model S. The garage where I'm parked has 2 GE wattstation chargers. I already had the smartphone Wattstation app on my iPhone, thinking it would be an advantage in these kinds of situations. Was I ever wrong. I've spent about four hours of precious holiday time with my family trying to get this app to turn on the Wattstation so I can charge my car. Nothing I do works. This app is the worst smartphone app I have ever encountered. The fact that Tesla has no superchargers in Manhattan is also a disgrace. What are they thinking? One has to rely on commercial garages for charging and they know next to nothing about EVs and charging. The garage I'm in is one such example. Their chargers are impossible to make operational with the Wattstation app and they know nothing about the problem.
