Wall mounting a tablet for control panel

I want to plug-in my tablet to a Smart Things power outlet. I’m thinking to create a tasker rule to wake up the screen when device is plugged in. So when motion is detected by a nearby motion sensor then webcore piston can turn on the ST outlet. But i want to also create something when battery of the device drops to 30% to turn the ST outlet on but not sure how can you have tablet status trigger a ST action?
