Because the problem is only happening at your house it is mostly likely something using your GPS. Do you have moto assist turned on for when your at home? If you do I would suggest turning it off and seeing if the battery is still being drained. If that isn't the cause try turning off your location services and see if that fixes it. If that fixes it you can look at which apps use the location service through the Google settings app - > location. It also tells you their effect on battery. Finally if none of the above work then disable Google now by going into the Google now->settings-> slide the Google now option and disable location history. You could also try another launcher like nova launcher: https://play.google.com/store/apps/details?id=com.teslacoilsw.launcher
