I'm using a SmartShunt in my RV, and have both android phones and tablets. I really wish there was an option in SmartConnect to disable the Android screen saver (much like Google Maps uses when you're driving), as if the screen sleeps, SmartConnect loses all history from the SmartShunt, and I want to be able to track the charging cycle overnight while I tune and adjust stuff. yes, I will ensure my Android device is plugged in if I enable this. in fact, I'd love to be able to mount an older 'spare' android tablet in the trailer as a full time SmartConnect monitor, hard wired to a usb charger).
I'm adding at least a MPPT 100/30 soon, and maybe some other Victron devices, so this likely will become even more of an issue (although I have yet to see how the SmartSolar MPPT interacts with the SmartShunt if I interconnect their DE ports).
