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.

A method for identifying an individual electrical device among a plurality of spatially-distributed electrical devices, each of the devices having associated therewith its own RF transceiver and its own microprocessor and associated memory for storing (i) an identification number and (ii) category information, where category information is: (a) information other than the device's identification number by which the device can be selectively communicated with, and(b) information that can be changed from time-to-time, the method comprising: (A) broadcasting, from a portable device, an RF discovery request to the spatially-distributed electrical devices requesting RF transmissions from the devices of identification information, the identification information comprising at least an identification number;(B) receiving, at the portable device, RF transmissions comprising identification numbers returned by devices as a result of step (A) and determining a perceived proximity for each received RF transmission;(C) ordering the identification numbers received in step (B) by perceived proximity;(D) selecting an identification number from the ordered identification numbers of step (C), the selected identification number corresponding to the device having the closest perceived proximity, and then, as selected by an operator, performing at least one of: (i) transmitting an RF signal to the device associated with the selected identification number so as to cause the device to produce a visual or audible signal;(ii) transmitting an RF signal to the device associated with the selected identification number so as to cause the device to store category information for the device;(iii) storing category information for the device associated with the selected identification number in a memory associated with the portable device and/or in a memory associated with a remote controller; and(E) as selected by an operator, repeating step (D) with at least one other identification number corresponding to a device having a perceived proximity greater than the closest perceived proximity;wherein the perceived proximity for each received RF transmission is determined from time of flight, received signal strength, or both time of flight and received signal strength. 2. The method of claim 1 wherein in step (E), the at least one other identification number is the identification number corresponding to the device with the next-closest perceived proximity. 3. The method of claim 1 wherein: (a) step D(ii) is performed for at least one device; and(b) the method further comprises: (i) changing category information of one or more devices using a category signal which comprises a message and, so as to determine which of the devices is to have its category information changed, at least one of: (1) the category information of step D(ii),(2) the category information of step D(ii) which has been changed one or more times,(3) one or more identification numbers, and/or(ii) controlling one or more devices using a control signal which comprises a message and, so as to determine which of the devices is to execute the control signal, at least one of: (1) the category information of step D(ii),(2) the category information of step D(ii) which has been changed one or more times,(3) one or more identification numbers. 4. The method of claim 3 wherein step (b) is performed from a portable device and/or a central controller. 5.

The method of claim 1 wherein the RF transmissions comprising identification numbers are returned by devices after a random delay. 10. The method of claim 1 wherein in step (A), the RF discovery request broadcasted from the portable device includes a signal strength threshold value which is used by devices to determine if an RF transmission comprising an identification number should be made. 11. The method of claim 1 wherein at least one of the plurality of spatially-distributed electrical devices controls another device. 12. The method of claim 1 wherein the plurality of spatially-distributed electrical devices perform generally the same function. 13. A system comprising: (A) a plurality of spatially-distributed electrical devices, each of the devices having associated therewith its own RF transceiver and its own microprocessor and associated memory for storing (i) an identification number and (ii) category information, where category information is: (a) information other than the device's identification number by which the device can be selectively communicated with, and(b) information that can be changed from time-to-time, the microprocessor being programmed to perform at least the following operations:(i) receive an RF discovery request from a portable programming tool; and(ii) transmit an RF signal comprising an identification number in response to the RF discovery request;(B) a portable programming tool comprising an RF transceiver and a microprocessor system programmed to perform at least the following operations: (i) broadcasting an RF discovery signal which requests spatially-distributed electrical devices to return at least an identification number;(ii) receiving RF signals from spatially-distributed electrical devices, the RF signals comprising identification numbers, and determining a perceived proximity for each received RF signal;(iii) ordering the identification numbers by perceived proximity;(iv) selecting an identification number from the ordered identification numbers, the selected identification number corresponding to the device having the closest perceived proximity,(v) receiving an operator input and based on that input, performing at least one of: (a) transmitting an RF signal to the device associated with the selected identification number so as to cause the device to produce a visual or audible signal;(b) transmitting an RF signal to the device associated with the selected identification number so as to cause the device to store category information for the device;(c) storing category information for the device associated with the selected identification number in a memory associated with the portable device and/or in a memory associated with a remote controller; and(vi) receiving an operator input and based on that input, repeating (v) with at least one other identification number corresponding to a device having a perceived proximity greater than the closest perceived proximity;wherein the perceived proximity for each received RF signal is determined from time of flight, received signal strength, or both time of flight and received signal strength. 14.
