Patent attributes
Systems for identifying and categorizing distributed devices, e.g., lighting fixtures and thermostats, is disclosed. In an embodiment, a user (200) sends a low power discovery message to devices (201) using a portable programming tool (100). The devices (201) within range respond with identification information. The portable programming tool (100) organizes the responses by proximity and sends a “flash” message to the device with the closest perceived proximity. That device responds with a visual or audible signal (202), allowing the user (200) to determine whether that device is the one intended for selection. If so, the user initiates a store routine in which identification information, including category information, is stored in one or more locations, such as, the selected device (201), the portable programming tool (100), and/or a central or local controller (1100). The identification and categorization can, for example, be used to automate load shedding and to reduce energy consumption.
