A system, comprising: a portable handheld device; and a plurality of wireless actuator assemblies (12,14,16), each of the plurality of wireless actuator assemblies including: an actuated component; an actuator configured to move the actuated component between a first position and a second position; a short range wireless communication module having a nominal communication range of less than 18,288 meters / 50 feet; an actuator controller operably coupled to the actuator and the short range wireless communication module, the actuator controller configured to receive one or more actuator commands from the portable handheld device via the short range wireless communication module and to send information to the portable handheld device via the short range wireless communication module; characterized in that, the portable handheld device is configured to determine an indication of a location of a particular wireless actuator assembly (12,14,16) that is installed behind a wall, a ceiling or other physical structure and hidden from view of the user of the portable handheld device relative to the portable handheld device as the user moves the portable handheld device around relative to the plurality of wireless actuator assemblies and monitoring a relative difference in signal strength of one or more wireless signals received from the short range wireless communication module of each of the plurality of wireless actuator assemblies including the particular wireless actuator assembly, wherein the portable handheld device is configured to display the relative difference in signal strength on a display of the portable handheld device to provide an indication of a relative distance of the particular wireless actuator assembly to the user of the portable handheld device, and once the indication of the location of the particular wireless actuator assembly has been identified, the user of the portable handheld device can select the particular wireless actuator assembly using the portable handheld device and display a screen on the portable handheld device that enables a user to test and/or troubleshoot the particular wireless actuator assembly by sending one or more actuator commands from the portable handheld device to the actuator controller of the particular wireless actuator assembly. a portable handheld device;
