It's been almost four months since my PW installation and I'm still having to "customize" it every day for time-of-use shifting. I've had several software updates both to the app and the PW itself, but I still have no TOU. How hard can it be for Tesla to provide a simple scheduler, such as the one in the NEST app? I just want to adjust the percent available for backup twice a day. Despite several "promises," innumerable emails, and even telephone calls I've had no luck. Apparently nobody at Tesla has a clue as to when it will be available for Arizona and APS.
