One aspect is an electrical junction with wireless controller configured for attachment in a building structure. The junction includes a junction body having surfaces defining an opening. A junction device is coupled to the opening of the junction body and a wireless controller is coupled to the junction body. An external conductor routs voltage from a voltage source in the building structure into the junction body. The wireless controller is electrically coupled between the external conductor and the junction device and is mechanically coupled to the junction body behind a surface of the building structure.
