I've been using it for sometime as I signed up for the beta testing...as you say the only problems start if the WiFi drops out...just have to check that everything is set up right on the day....using it in the early hours with octopus go at 5p a kW is a really big savingI used it the first time last night and worked a dream. I had to disable the hack I had made to PP Solo so that it would enable it to be controlled by the PodPoint sever. The only issue I can see is that interrupted WiFi or loss of Internet connection will turn on the charge whereas my old hack has an internal timer.
